In May, the maximum temperature during the day in the Beiku area has risen to more than ten degrees, but the minimum temperature at night is still about minus five degrees, and the temperature difference between day and night is very large.

When Li Zhan piloted the No. 02 SU-27SK heavy fighter to land at Nankuchang Station, Niu Yaoyang and Miao Yu's maintenance team were already waiting on the tarmac. Under the roar of the AL-31F engine, the empty Nankuchang Station finally ushered in a glimmer of life.

Shi Zezhong of Nankuchang Station is also looking forward to it on the tarmac.

The North Reservoir Station has been reorganized and upgraded to a combat training base, and most of the cadres have been promoted on the spot, and this temptation is really difficult for Shi Zezhong to resist. In any case, the Nankuchang Station is also one of the stations of the 101st Brigade, and it should be treated equally. It became more and more important to have a good relationship with Li Zhan, who had a very high prestige and great influence in the 101st Brigade.

Today is May Day, the third day that the southwest modified J-10A detachment of the Eagle Falcon Brigade withdrew to Beiku, and the 101st Brigade received an order from the duty room of the Air Force of the Military Region, requesting that a fighter plane be dispatched to support the local area in carrying out a special task -- to assist the farm in spraying pesticides on the cotton fields.

That day, after Xue Xiangdong consulted his superiors, the air division issued an order in the afternoon of the same day, ordering all the trained pilots of the Eagle Falcon Brigade of the 101st Brigade to return to the Beiku Combat Training Base to resume normal training. As for whether the J-10A will still be modified, there is no clear result for the air division.

However, everyone knows that when they came back this time, the Eagle Falcon Brigade basically had no chance with the J-10, so that everyone sighed that the J-10 was really the captain's unicorn, and something would happen as soon as it was combined, and it was a big deal.

The main reason why Li Zhan strongly recommended that he take the initiative to return to Beiku was that he was keenly aware of some positive changes in the general environment. One of his most powerful judgments is that it is very likely that the Air Division will replace all the second-generation aircraft of the 101st Brigade with the J-11B. His basis is very simple - the senior brother who flew the fourth-generation aircraft in Chengluoma told him that Shen Hoyi had solved the problem of the domestic TH engine.

As far as Li Zhan knew, because of the unexpected lag in the development progress of the engine, Shen Huoyi had a large backlog of airframes that only lacked engines. In other words, as long as the engines are in place, Shen Hoy can deliver dozens of fighters to the army in a very short time.

No one knows better than Li Zhan what kind of aircraft the Eagle Falcon Brigade and even the 101st Brigade need most, although he personally likes the J-10 villain A small curled lip B, but it must be admitted that a heavy twin-engine long-range fighter like the J-11 is the best choice for the 101st Brigade with a vast jurisdiction.

Therefore, he clearly expressed his attitude and suggestions to Xue Xiangdong from two angles at that time.

The third factor is the intervention of the Water Capital Eagle Division, and the impact is on the table and does not need to be analyzed.

Based on this, it is more in line with the future development of the 101st Brigade to take the initiative to request withdrawal than to stay at the good station to entangle.

After returning to the Beiku combat training base, Li Zhan immediately engaged in a day's ideological education to restore the low morale, and the training of the Eagle Falcon Brigade quickly resumed, but May Day was a legal holiday, and the Eagle Falcon Brigade was also rested.

In order to let the soldiers have a good rest, Li Zhan decided to personally fly the plane to carry out the task of assisting the local pesticide spraying. He's not really paying for that little pull-up fee.

"Stationmaster Shi, the disaster is so serious that you need troops to send out support?" As soon as he got off the plane, Li Zhan saluted first, and then asked Shi Zezhong directly.

Shi Zezhong returned the salute and said, "It's very serious, Team Li, let's talk while walking." ”

Li Zhan motioned for him to wait, walked over and talked to Niu Yaoyang and Miao Yu, "This is Chief of Staff Yang Jinshan's landline, you guys should be better." ”

His No. 01 SU-27SK fighter was gone, and he had to drive someone else's to carry out the mission. The body does not have much life, but it is better than the situation of the previous No. 01 SU-27SK.

Miao Yu said, "Captain, as long as you drive leisurely, it's definitely no problem." ”

"How else can I open pesticides. This fighter jet spraying pesticides can be regarded as a test of kung fu. Li Zhan shook his head helplessly and said.

Niu Yaoyang said, "No problem, when the local sprayer is sent over, I can do it in two or three hours, and Su Erqi's low-altitude performance is completely competent." ”

"It's still too fast, and this kind of live luck is the most suitable for these small propeller planes." Li Zhan said.

Miao Yu said, "The local agricultural planes are running at full capacity, otherwise they would not have asked the troops for help." I heard that the Army Aviation Brigade is also going to pull out planes to help. The cotton fields in the North Reservoir area are too big. ”

"Be serious."

Li Zhan waved his hand to explain a few words, walked over and got into the commuter car with Shi Zezhong and went to the infield.

In the car, Shi Zezhong said solemnly, "The North Reservoir area is an important cotton planting area, this year's planting area of 10 million mu, equivalent to half of the capital city area, mainly concentrated in the south of our South Reservoir Station, the south of the basin, that is, the south of Ulun Lake, most of them are farms, and a small part is planted by the people. May and June are important times for pest control, and how well insect control work is done directly affects the harvest in September and October. Therefore, the local government attaches more importance to it up and down. ”

"But this year, the situation was very sudden, and the insect infestation broke out almost overnight, and then spread at a very fast speed, which caught everyone off guard. Last night, the Army Aviation Brigade dispatched 12 helicopters to assist in spraying pesticides, but it was a drop in the bucket. ”

Li Zhan interrupted Shi Zezhong's words, "Wait, Stationmaster Shi, the twelve helicopters of the Army Aviation Brigade have gone up to return the vehicles, what is the use of a fighter jet in my mere mela?" ”

"Fighter jets are fast, and they have to race against time, and the shorter they spill pesticides, the less damage they will lose." Shi Zezhong said.

Li Zhan shook his head wordlessly, "That's not how it is calculated. There is a speed requirement for spraying pesticides, and the speed is fast and the pesticides will volatilize before they reach the ground, so what's the use of being fast? ”

He doesn't know how to spray pesticides, but he knows that the use of any mounted weapon requires flight altitude and speed, and it is not something you can do when you hit it. For example, the YJ-91 air-to-surface missile, if you want the missile to hit the farthest, you must launch it at the specified high speed, such as 12,000 kilometers, and it cannot be higher or lower.

There are strict operational requirements.

You launch an air-to-air missile with ten overloads, and even if you lock on to the enemy aircraft, the missile will not be able to hit the enemy aircraft, because the missile will either not hit or will disintegrate in the air not long after it is hit, because the overload on the missile exceeds the design value!

"This ...... After a while, you talk to local agricultural experts, and I don't know much about it. Shi Zezhong said, "The situation reported by the local government is very serious and critical, and if this war with pests is not won, the cotton output of the entire Beiku region this year will be devastated." ”

In fact, the leaders of the 101st Brigade did not know much about the situation, and they received orders from their superiors to send excellent pilots to fly the SU-27SK to the South Reservoir Station to assist the local authorities in completing the pesticide spraying task, and there was nothing else.

The Nankuchang Station is only a few dozen kilometers away from the millions of acres of cotton planting area in the south, and local agricultural experts have already arrived here, waiting for Li Zhan's arrival.

On the second floor of the station's only building, a section chief and three agricultural professionals from the local authorities are already waiting anxiously. The range of pests is constantly expanding, and for them, time is measured in hours, and it is a forest fire battle for agricultural pest control, which is very urgent.

"The pilot has arrived, this is our best pilot, Captain Li Zhan Li." As soon as he entered the conference room, Shi Zezhong introduced.

Li Zhan saluted them, "Knowing that the situation is urgent, what should I do?" ”

The section chief, who was preparing to greet him, was not very suitable for the style of the troops, and he was embarrassed there. However, the oldest agricultural expert, who had white hair, simply said, "Captain Li, I want to open up an insect-proof belt in the shortest possible time, and the time is very urgent." ”

Maps are already laid out on the conference table.

Li Zhan didn't even put down the flying helmet, directly clamped it under his ribs, put the white labor protection hand suit he took off into his pocket, and walked over.

Pointing to a straight line drawn on the map from east to west, the agricultural expert said, "From Dongli to the south of the Shuihe River, we must urgently open up a barrier about two kilometers wide, cut out all the cotton fields that have not been infested, and isolate the parts that have been infested." ”

"Like a firebreak?" Li Zhan suddenly understood the reason for letting him fly the fighter jet.

The entire isolation zone is a cutting line from Kudongli in the north of the capital to the south of the water river, and the whole field is about 700 kilometers. The whole journey requires a low-altitude flight, except for the SU-27SK, no fighter can fly two round-trips, and it is even more impossible for agricultural planes, and helicopters of the army aviation brigade cannot do it.

"That's right." The agricultural expert said solemnly, "The separation zone about two kilometers wide, saturated spraying at an altitude of 144 meters, has to fly two round-trips." ”

The maximum range of the SU-27SK will not exceed 1,700 kilometers, which means that it will be enough, leaving a redundancy of about 200 kilometers. Flying two round-trips is 2,800 kilometers, which means that Li Zhan needs to land and refuel once.

No wonder the superiors designated to drive the SU-27SK over, except for this long leg, none of the fighters in service can complete such a special spraying task with only one landing and refueling.

In addition, the minimum allowable speed of the SU-27SK at low altitude is 200 km/h, which is also an advantage of spraying pesticides. Even non-professionals know that it is almost impossible for agricultural planes and helicopters to spray pesticides at speeds greater than 200 kilometers per hour. Estimates of the performance of the aircraft have already been submitted to agricultural specialists, indicating that the SU-27SK is competent, otherwise such a scheme would not have been worked out.

Li Zhan carefully looked at the special map of the agricultural department, most of which were marked with agricultural planting areas, which were different from ordinary maps and military maps.

He frowned and asked, "Has the insect infestation spread from the water river to Beikudongli?" ”

This is definitely a big event, and I can't take it too seriously.

However, the agricultural expert shook his head and said, "No, just this one south of Lake Ulun." But in order to be sure, the higher authorities demanded to expand the scope of the defense, urgently spraying the entire cotton-growing area of the North Reservoir region. The purpose of the barrier is to control the extent of the pest infestation first, and then further spray the pest area. Captain Li, in addition to you, we also asked the helicopter unit to help us carry out the second targeted spraying of the isolation zone, and on the ground, we mobilized tens of thousands of people to start from the isolation zone and go south to carry out carpet spraying, and resolutely win this cotton defense battle! ”

Li Zhan was shocked, isn't this a saturation rescue?

He had already noticed at this time that the insect infestation area was all marked red, and from the map, it was only a small area south of Lake Ulun, so there was no need to be so excited!

Perhaps seeing Li Zhan's doubts, the agricultural expert explained, "This pest outbreak was very sudden, and this situation has not occurred in previous years." The most important thing is that it spreads quickly and is extremely damaging to cotton. Our experts are working the analysis, but one thing is for sure, our drugs are effective against these pests. The instructions from the higher authorities demanded that the scope of the pest be controlled at all costs, that the threat of pest infestation be eliminated in the shortest possible time, and that the property losses of the masses of the people should be reduced to the greatest extent. ”

Li Zhan couldn't help but glance at the agricultural expert a few more times, and spoke like an official more than a technical expert.

The section chief coughed and said, "Stationmaster Shi, Captain Li, this is Deputy Director Zhong of the Research Institute of our Regional Agricultural Bureau. ”

Deputy Director Zhong looked ashamed, "Our work is not in place, and this sudden pest infestation really makes it impossible for us to deal with it in time, so we ask the comrades of the army for help." ”

"Director Zhong, the theoretical minimum speed of my plane can reach 200 kilometers per hour, but that is already close to the envelope, if the speed is higher, will it affect the effect of spraying?" Li Zhan is more concerned about how to complete the task well.

"As long as it does not exceed 250 kilometers per hour, it will not have a great impact on the spraying effect, and we have considered redundancy when formulating the route plan." However, the flight path must be as accurate as possible, which is related to the spread of insect infestations. ”

"Understood, just give me the navigation point. In addition, the weather factor is taken into account, the wind direction and wind force will affect the spraying area. Li Zhan said.

Deputy Director Zhong said, "It has been included in the calculation, the provincial meteorological observatory has given very accurate data, we have coordinated the civil aviation department to send several teams of personnel have been stationed at several points, which can guide the aircraft in sections and confirm the direction, and at the same time there are weather vehicles to follow the real-time field collection of weather data." ”

Generous.

It's amazing enough to coordinate so many departments and mobilize so many resources.

Li Zhan said, "I have no other problems, and I can leave at any time." ”

He appreciates this saturation approach, especially in the face of emergencies, where the investment of excess rescue resources and forces can minimize the loss and control the scope of the impact as quickly as possible.

In just one month, China mobilized more than 300,000 officers and men of the People's Liberation Army (PLA) and the People's Armed Police Force to fight the flood and rescue the flood.

In the 308 earthquake, we mobilized more than 100,000 troops from five military regions and more than 20 arms to participate in the rescue work within three days, and during those three days, the country's fire fighting system, health system, railway system, and communication system were invested in disaster relief at any cost.

The number of rescue and disaster relief personnel even exceeds the number of people affected by the disaster in Wenchuan!

One in 1998 and one in 2008.

Now in 2011, Li Zhan firmly believes that the pests in the cotton planting area in the southern part of Beiku will be eliminated by saturated resources in a short time.
