Behind the embankment. It is a high-yield field of just one acre in the first phase. Bird's Nest and Mo Nanhai! Daolu and the others will discuss. It was decided to construct and transform farmland with early harvest and high and stable yield, which must meet the following standards: drought resistance to achieve a bumper harvest without rain on a fierce day; The drainage has reached the standard of the century of the old year, and the daily rainstorm does not become a disaster; The riverbank flood control levee reaches the flood level of one in the public year plus level 8, and the wind does not collapse or overflow; Flat land to soil to achieve paddy field living soil layer depth inch, dry land, feet. The ability to retain water and fertilizer has been greatly improved.

Fields are squared. The square area should be large to facilitate the operation of agricultural machinery. Drainage and irrigation sub-channels. Ditches, canals, roads, and forests. In particular, it is necessary to gradually build farmland windbreaks to reduce the impact of typhoons in summer and autumn every year. The field roads should be at a level that can drive mechanized vehicles

After the discussion was settled, the bird's nest began to work on the survey and design. Wu Nanhai and Fa Shilu began to mobilize peasants and workers on a large scale to make preparations, and to prepare sufficient base fertilizer for each biogas digester and compost pond. A steady stream of materials for water conservancy construction was brought to the construction site: plant ash and lime were used for soil modification. bricks, stones, cement, timber, and bamboo bars for pouring concrete for the construction of embankment channels; The machinery factory is responsible for manufacturing various valves and pipes used in water conservancy facilities. At the same time, the manufacture of pumping machines, supporting boilers and steam engines began.

The work was first carried out by a large number of laborers sent by Gao De, who carried tools such as axes, saws, and sickles. A comprehensive clean-up of vegetation in the entire development area was carried out, where the vegetation was mainly small shrubs and weeds and small shrubs used as firewood, and after the weeds were harvested and the dead grass and fallen leaves were piled up in several temporary compost ponds in Wunanhai, the biogas mud from the biogas digester was used as a primer to mix it. The outside is covered with soil and watered regularly, and in the summer sun, the plants will soon be broken down into organic fertilizer.

If they are buried directly in the soil, some of the branches and leaves of plants and trees with heavy fibrous texture will not decompose even after many years, and will not play a role in fertilizing the field.

After clearing the vegetation, four bulldozers led by Bai Yu, the commander of the armored corps, came, and the Dongfanghong tractor with a bulldozer shovel was installed. White Feather poked his head out of the cab. Yan Quezhi and the others were already waiting for him in the headquarters, and the construction route had been marked on the map.

The first step was to carry out a comprehensive leveling project on the developed area with a bulldozer. Removal of residual vegetation from the surface. Remove large stones, the latter should be especially careful. lest you damage the bulldozer blade and tracks. Each bulldozer is accompanied by a squad of Army soldiers, who search in front of the bulldozer in a scattered formation.

"It's kind of like a step-by-step synergy." Yan Quezhi climbed on the cab and said to Bai Yu.

"If the oil and cool parts of the bulldozer can be used openly, I won't go to Beijing immediately, and why bother to open up wasteland and build roads here." Bai Yu stared ahead. Constantly pushing and pulling the joystick in his hand. From time to time, he also yelled a few times on the walkie-talkie. To other tractors "pay attention to the distance between each vehicle and maintain coordination."

"Tractor Armored Division?" Immediately in front of her eyes, such a scene appeared: smoke and dust billowed on the dirt road. The tracks of the Dongfanghong tractor, which was in sight, were crushing the earth, and the tractor was full of riflemen known as "tractor grenadiers", wearing bearskin hats and holding mini bugs.

It feels so weird! Bird's head snapped.

"Nothing impossible." Bai Yu was full of confidence, "Small! Roads and water networks are not good, but they are definitely a weapon on the Great Plain of North China. Look at this," he said, gesturing to a few protruding pieces of hardware outside the cab, which seemed to have been installed later, not the original parts of the tractor.

What is Glance? "Bird's Nest Banner bowed loudly

"Fixtures for hanging armor plates." Bai Yu was very proud, this was designed and manufactured by him himself, "When needed." The key parts of this tractor can be fully armed and invulnerable in half an hour. The bulletproof specification is strong enough to resist the direct hit of a solid bullet like a meter away from the cannon, right? ”

"Such a big iron ball hit directly, and the people in the cab were not shocked to the point of bleeding from their mouths and noses

"The enemy can only be hit well," Bai Yu didn't seem to be too worried about this, "Besides, we don't sit and get beaten. You look at the top. ”

At the top of the tractor, there is a new sunroof that resembles a car sunroof, surrounded by something like a slide rail. The sunroof is open, bringing some cool breeze to the hot cab.

"I got a modification kit that can add a rotating turret directly to the roof part above the sunroof, and even if there is no machine gun, you can beat the enemy with a half-drop, and if necessary, you can use grenades and grenadiers to be invincible."

"Really creative"

"What is this, I studied weapons design and engineering design." The former armored officer was very proud, "There's also a Spitfire tractor conversion kit." It's a pity that there is not enough oil

He then went on to talk about several weapons he had designed, basically around tractors, cars, motorcycles and even bicycles. The latest design is to install a four-barreled "hand-held shotgun" on the weighted agricultural bicycle commonly known as Feida, which uses the rapid mobility of the bicycle to launch close and disturb the opponent's formation. Another modification is to install a fixed carriage for rifle shooting on the bicycle, which allows the rider to shoot at the same time as the bicycle, and by the way, this carriage also supports a pulley crossbow.

Generally speaking, the things designed by Bai Yu are relatively "modern", and he scoffs at the things of the "retro school" weapon designers led by Lin Shenhe.

After the clean-up, the waste soil excavated during the construction of the construction tide was brought from various construction sites. Yan Quezhi is going to raise the United States and Taiwan as high as possible, even if it is one or twenty centimeters. In this way, a large amount of waste soil generated by construction work in various places is also disposed of.

All land leveling was completed quickly. Then the tractor is attached to a heavy plough for deep ploughing and ploughing. A large amount of quicklime brought in from Bopu was applied to improve the soil. The amount of lime used has halved the supply of quicklime on all construction sites. In addition to working overtime at the quarries, all the personnel of the army and navy who were not on duty were mobilized to go to the coast to mine the dry houses to replenish the raw materials for burning lime.

Construction of the dam has also begun. Due to cost constraints, the dam is a simple gravity earth dam reinforced with rows of wooden piles. The perimeter of the earthen dam is covered with stones. The dam is more than 100 meters away from the Wenlan River's highest water mark during the rainy season, and serves as a flood channel during floods. When the water level is low, watermelons and peanuts are grown by taking advantage of the sandy soil on the riverbank.

Irrigation gates and drainage gates are now set up on the water to accommodate the arrangement of channels where irrigation and drainage are separated. The gates are opened and closed in a mechanized way. The power of opening and closing is to use the power of the steam pumping station on the embankment.

Connecting the two gates are two main channels, both constructed of bamboo-reinforced concrete, with sufficient margin for design flow standards to meet the needs of irrigation and drainage in extreme environments. Other irrigation and drainage canals in the field are connected to the two main canals, and the mouth of the canal is equipped with a sluice gate that is opened and closed by manpower.

For the large amount of spring water flowing from the hilly terrain, it is easiest to simply intercept it with a drainage channel and discharge it into the Wenlan River. But she thinks it's a waste of water. From the perspective of early prevention, he decided to use the natural terrain to build ponds and dams in hilly areas to store water. The dam project was built in this way, and the dam collected the spring water to irrigate the farmland during the dry season of the Wenlan River, reducing the amount of water used by the river, after all, the river is now the lifeblood of the entire crossing group, and the amount of industrial and domestic water is not used

The pond dam reservoir built by taking advantage of the natural terrain of the hills can not only regulate the storage of water and beautify the environment. Fish can be raised in the sugar dam and used to generate electricity. It's a lot of money. Wang Luobin has a lot of experience in building such a small water conservancy project, so he will be the general contractor of this part of the project.

In addition to building the dam, Wang Luobin also selected a number of economic tree species adapted to the local climate in the farm's nursery to green the hills around the dam, and built a small hydropower station on a larger dam. It's just that the power generation power is too much and can only generate electricity in stages, which is of little use, and is purely of a research nature.

The basic construction of farmland water conservancy is being carried out vigorously.

Wu Nanhai went to the executive committee to find Ma Qianzhu. I asked him to help solve the problem of fertilizer.

Because the long-term internal filling of the United States and Taiwan Ocean causes the soil fertility to be very strong, the application of lime can only neutralize the acidity, and cannot improve the fertility and trace element content of the soil.

Fa Shilu said: "The United States and Taiwan should add a large amount of nitrogen, phosphate and potassium fertilizers. Especially phosphate fertilizers. The lack of phosphorus is very serious, and you can't grow leguminous green manure if you want to, so add farmhouse fertilizer as the base fertilizer after the trace elements are adjusted. ”

Farm manure and green manure alone seem to be abundant, but in terms of improving fertility, it is far less effective than the fertilizer that has changed the trend of modern petty bourgeoisie. However, the nitric acid they brought with them became the explosives of the Military Commission under the guidance of "Songun Politics".

"Nitrogen fertilizer is easy, let the executive committee think of brown butterflies or peat for us. Phosphate fertilizer, potassium fertilizer, where can I find it? Wu Nanhai muttered, "There isn't so much bone meal." ”

"Both lignite and peat are good." Fa Shilu said, "Natural compound fertilizers, nitrogen, phosphorus, potassium are available, and the efficiency is much higher." However, the amount is not enough for soil improvement. It is best to have specialized phosphate and potassium fertilizers. ”

Potash fertilizers can be met by the bitter brine industry of refined salt plants to produce potassium chloride by-products. Coupled with the bell element contained in peat lignite, it is roughly enough. If you want to know what will happen next, please log in to the state.
