It rained for several days in a radius of 100 miles that covered the saline-alkali land.

It's not a downpour, it's a rainy season with normal rainfall, but not a short duration.

The most gratifying thing is the team of saline-alkali land treatment and transformation.

Jiagu and others were naturally happy, the rain was drenched with salt, not to mention the large amount of money saved, and the progress of the project was significantly accelerated. Although the problem of groundwater still exists, can't it be slowly treated?

The agricultural labor team is also happy that their rewards are not increased by delaying the construction time, but are awarded according to the progress of the construction. As for the need to carry out surveys and adjustments such as drainage in the rain from time to time, Jiagu logistics are doing a good job anyway, and there are subsidies, so it is not a matter of hard work.

Although Dr. Li Weixin has mixed feelings, the team he leads is also very happy. How to make better use of the power of nature to manage saline-alkali land is another topic worthy of study. Although this situation is rare at the moment, it is still an example, and for them, it is enough to publish a few papers on related topics.

In short, it's a happy outcome.

With such just the right amount of "luck", needless to say, it was naturally Qi Shen Stick Zheng who made a move.

To be honest, this is a bold attempt even for Qi Zheng.

"Tiangang Wuji Array (Second Order) triggered, the main gold and water systems, range: 200 kilometers in radius. Effect: Extreme pressure, wind. It can control the air pressure, and the wind and water rise. ”

For this "weather toy", Qi Zheng has long been eager to try.

And this time, in order to meet the needs of saline-alkali land management, Qi Zheng played a big game.

After the agricultural reclamation labor team successfully entered the construction site, he left here, rented a speedboat, and went to the sea for a vacation, in essence, to do things.

In the past, they were all deployed on land, but for the first time, they were completely transferred to the sea, and Qi Zheng explored a lot before he successfully deployed the formation at sea as he wished.

This time, he focused on the annual typhoons along the coast.

Because of the unpredictability of the typhoon, the spirit array arranged by Qi Zheng adopts a trigger-type control mode.

In other words, only when a typhoon is sensed will the Spirit Array trigger its operation.

As he became more and more proficient in the application of the Spirit Array, some of the small techniques of arranging the array also became more and more proficient.

Qi Zheng's first goal is to control the path of the wind.

In order to avoid an uncontrollable disaster caused by mistakes, Qi Zheng could only toss at sea. He arranged several "Tiangang Infinity Arrays" along the coast, and "lured" typhoons into the game by generating high and low pressure.

Therefore, Qi Shenzhu Zheng has the confidence to gamble on the probability of a typhoon crossing in front of Dr. Li Weixin.

The typhoon came and went as scheduled, and with a wave of its sleeves, it brought a heavy rain.

Under the influence of several "Tiangang Infinity Array", this year's Typhoon No. 12 drew a strange trajectory, parallel to the coastline, but did not make landfall.

In the end, it dissipated in the East China Sea through the offset of the spirit array.

A typhoon that may bring great disasters was "tamed" by Qi Zheng in this way, and Qi Zheng's heart was not shocked...... What a fart!

Actually controlling a powerful and extremely destructive meteorological "bad boy", Qi Zheng's heart didn't know how excited he was.

Probably everyone has a desire to destroy in their hearts, and the effect of the spirit array arranged by Qi Zheng before is of course very magical, but the feeling for Qi Zheng who has the array ring is just like that, not to mention an indescribable surprise.

But this time, it seems to have opened the door to a new world for Qi Zheng, and the feeling is completely different.

Think about how many bad things you can do without knowing how many bad things you can do with this ability...... Ahem, something that benefits the country and the people......

Alas, he was, after all, a good man with good manners.

Well, in fact, Qi Zheng has done so much just to verify the conjecture in his heart to use the Spirit Array to control the meteorological disaster. Otherwise, a "five-bucket cloud rain shower" can solve the rainfall problem, after all, it is on the seaside, how trouble-free.

In short, Qi Zheng's face was not obvious, and he didn't know how many thoughts of pit people had popped up in his heart.

In the end, he still pressed the impulse in his heart, and wanted to stir up the wind and rain, it was best to toss it abroad, and it was better to keep the years quiet at home.

......

Filling with water and salt had an immediate effect.

As the clouds cleared and the sky cleared like a wash, the air smelled of the scent of earth after the rain.

Dr. Li Weixin immediately measured the salt content of the soil after rainfall.

The results showed that the soil salinity decreased significantly, and the soil was basically improved from moderate saline-alkali land to mild saline-alkali land, which has the potential for agricultural development.

Of course, the side effects of rainfall washing salt are also clear at a glance.

Groundwater levels remain high, soil nutrients are lost massively, and organic matter levels are kept to a minimum......

In a word, the ground is not salty, and it is completely "bald".

With the quality of today's soil, no matter what crops are planted, they are destined to have no harvest.

Moreover, even mild saline-alkali land needs to be planted with saline-alkali tolerant crops, and it will take at least two or three years to completely transform into fertile land.

"At this point, you can't rush. It is necessary to comprehensively adopt biotechnological measures for improvement. Planting salinity-tolerant plants can not only prevent wind and stabilize soil, regulate surface runoff, change soil structure, improve soil fertility, and inhibit surface salt, but also reduce surface salt by evaporating water, lowering groundwater levels, and reducing surface area salt. Dr. Li Weixin said and glanced at Qi Zheng.

Qi Zhenghao was speechless, as for it, didn't he just ask to speed up the progress before the typhoon came? He is not a person who is eager for quick success, can he not know this truth?

Seeing that Qi Zheng had no opinion, Dr. Li Weixin said with satisfaction: "Because you originally planned to build it as a pasture, it is more straightforward, alfalfa itself has the characteristics of developed root system and strong salt tolerance. ”

"Although it is the end of August, which is not the best season for pasture planting, the effect can be quite obvious by mixing crops such as alfalfa and milk vetch, ploughing them into the ground in the following spring, using them as green manure to improve the soil, and then replanting the pasture......

Needless to say, alfalfa is known as the "king of forage", and has the advantages of fiber plants and protein feed, and is the most widely cultivated forage grass in the world.

Chinese milk vetch is not only a pasture grass, but also commonly cultivated as green manure, and is the most familiar "fertilizer treasure" for farmers. It can absorb nitrogen from the air through the plant and fix it in the soil by rhizobia.

It has been estimated that after planting milk vetch, the amount of chemical fertilizer can be reduced by 30%, and soil fertility can be significantly improved two to three years after planting.

This is an excellent choice for barren land after salt washing.

As Dr. Li Weixin said, it is now the end of August, and the construction of the pasture has not yet started, so even if the grass is planted immediately, there will be no harvest, so it is better to simply use it to plant green manure, and return it directly to the field as green manure in the next year to further improve the soil structure.

Chen Jianzhang also added: "Our laboratory has also developed a microbial fertilizer for saline-alkali soil, which can be used to improve saline soil through microbial adsorption and enrichment, redox, mineralization and precipitation and synergistic effects. After the test, the application of active microbial fertilizer can improve the soil properties, and it is also beneficial to increase crop yield, which can be combined with the comprehensive utilization of organic fertilizer. This is a long-term foundation process......"

Listening to the plan of the two big bulls, anyway, it is emphasized that the next step is to improve the physical and chemical properties of the soil, improve the desalination effect, and fertilize the soil, which is a slow process, and cannot be rushed or waved.

Qi Zheng: "......"

Who's squandering?

Forget it, I don't bother to delve into their psychological shadows, anyway, they are all big bulls, so I will listen to them.
