As Master Liu said, the use of biological sand fixation technology for vegetation restoration can effectively improve the land properties in the sand area, so as to effectively play a role in wind prevention and sand fixation.

Desertification control is a systematic project, and Wei Ming has a full understanding of this.

After successfully finding a water source in the desert and possibly even changing the ecology of the Northwest, he is no longer a nobody in Jiagu, so he has been promoted to the management of the Jiagu Desert Management Team, responsible for coordinating and promoting the ecological restoration of the desert, in short, planting trees and grasses.

But planting trees and grass requires more planning.

The reason why desertification is called "the cancer of the earth" is because, on the one hand, it directly swallows up the land, which is the foundation of human existence, and creates batch after batch of "ecological refugees"; on the other hand, it is even more difficult to prevent and control desertification, and "controlling deserts is like throwing money into a bottomless pit" with large investment, long cycle, and slow results.

Qi Zheng once pointed out at the mobilization meeting of Jiagu desertification control: only by finding a balance between the interests of "ecology, economy, and people's livelihood" can we stimulate the motivation for desertification control, accumulate financial resources for desertification control, and achieve sustainable desertification control. As the saying goes, "if you don't cure the poor, you will end up empty".

Especially when facing the management of the desertification control team, Qi Zheng was more outspoken: ecology is the foundation, economy is the driving force, mainly referring to the company's money, and people's livelihood is the guarantee, mainly referring to the government's guarantee.

For example, if we change the group of "temporary workers" who joined the Jiagu desertification control war into a new identity: they will form a migrant workers' union to follow Jiagu to plant trees and become planters, work in Jiagu and become industrial workers, and lead them to engage in the desertification control tourism industry and become industrial shareholders...... Each new identity can bring them a lot of income.

If Jiagu can do this, if the government does not support Jiagu, who will it support?

In the first year and even in the second year, the management of the desertification control team should not think about what output it can achieve, but first of all, it is necessary to restore the ecology, improve the sandy soil, and lay a good foundation for the next step of development.

As soon as these words came out, the management of the desertification control team breathed a sigh of relief. With such a large investment, the company is not in a hurry to make revenue, and for them, it can control sand more calmly.

In accordance with the instructions of the big boss, the Jiagu desertification control team formulated a sand control development strategy of "locking the surroundings, infiltrating the abdomen, dividing and governing, and exploring the industry with points". At the same time, we should adopt the sand control method of "arbor if it is suitable for arrigation, irrigation if it is suitable for irrigation, grass if it is suitable for grass, and combination of arbor, shrub and grass".

Wei Ming led another group of employees to carry out "fancy" green plants in the paved grass grid.

In the desert area closest to the water point, there is an abundance of water, and the soil is mainly improved.

In addition, the technicians of Jiagu Laboratory got up early in the morning and traveled in the desert to retrieve various soil profiles for fine physical and chemical analysis.

With accurate scientific data, it is like a skilled old Chinese medicine doctor who has cut the pulse, which plot has the ratio of water to fertilizer, what plants are suitable to plant, and to what extent the soil can be improved...... A number of specific implementation plans have gradually taken shape in the desertification control team.

The laboratory-grown milk vetch was the first to break through the ground and clothe the grass squares in green.

This milk vetch, which contains a variety of nutrients and a large amount of organic matter, has been proven to be effective in fertilizing the soil, improving soil structure, promoting soil maturation, and enhancing soil fertility.

After a certain period of growth, the green stems and leaves of the milk vetch are cut off and turned directly into the soil, which can save manpower and reduce the transportation cost of organic fertilizer.

According to the experimental data, 1000 kg of milk vetch fresh grass cultivated by the group per mu can provide about 15 kg of nitrogen, phosphorus and potassium, and can net increase soil humus by 100 kg, which is equivalent to a 10-fold increase in organic matter and effective nutrients in the sandy land.

......

In the middle of the sandy land, in order to further explore the path of desert development, the desertification control team introduced a more magical plant Juncao.

Juncao is the product of the fusion of "fungus" and "grass", which subverts the existing cognition. Juncao can be widely used in the cultivation of mushrooms, fungus and other edible and medicinal mushrooms, which solves the problem of "fungus forest contradiction" caused by the need for segments of trees or sawdust to grow mushroom products.

The magic of it lies in the fact that although it looks like a sugarcane and is taller, some people say that it costs water and fertilizer at first sight, and it is difficult to promote it in arid areas, but the Jiagu laboratory has found that Juncao is easy to survive and more water-efficient.

Wei Ming looked at the lush and verdant Juncao growing on the sandy ground, which was said to grow to three or four meters or even higher, and really felt that this was a treasure for sand control.

With a row spacing of 1.5 meters, it can fix 15 square meters of mobile sand in about 80 days after planting, and its root system is deep, which can effectively fix precipitation and soil, and even in areas with harsh climatic conditions, the root system can still play a role in sand fixation for 4 to 5 years after the annual Juncao is harvested.

The most important thing is that the utilization value of Juncao is also quite high. It can not only grow fungi, but also raise livestock, with a crude protein content of up to 15 and high nutritional value, and is also used as a high-quality raw material for organic fertilizer production......

Whether it is milk vetch or Juncao, it is separated by a series of windproof and sand-fixing green barriers.

It is not easy to grow a tree in the desert than to grow grass.

Especially for the periphery of the "lock edge" of millions of acres of sandy land, far away from water sources, the conditions are difficult, in order to form a thick green barrier, Wei Ming even personally led the team to plant Suosuo.

It is a large shrub in terms of life form, and it can grow to more than 5 meters high in a good growth environment, which is a typical forest of Axony amon. It is not only a desert guardian of windbreak and sand fixation, but also inoculating the Chinese medicinal material Cistanche in the roots of H. amoxylon is also a sunrise industry with good economic benefits.

The tree planting team planted trees on the periphery and explored a new technology. This method eliminates the routine of sand fixation first, directly use an iron pipe to make a 1.2-meter-deep hole in the sand, then fill the hole with water, and insert the saplings that have grown directly into the hole, and plant a tree for two people in 10 seconds.

But Wei Ming expressed some doubts about this so-called "new technology", he didn't know if the survival rate was really guaranteed for such planting, this was a more practical desert tree planting method that Kubuqi explored two years later...... Of course, it is only suitable in desert areas with abundant water resources.

But in any case, compared with the grass grid sand fixation team and the grass planting team, the tree planting team is busier, especially in the desert rainy season, as long as they see the rain, the big guy immediately put on a raincoat, bring tools, rush to the sand nest to plant trees, in order to seize the time to plant trees, and even use a flashlight at night to illuminate and plant in the sand nest overnight.

Hard work is hard work, but the results speak for themselves.

The trees in the desert are simply magical, and the ground on which the trees are planted is sand, without any auxiliary soil, but the small trees grow on the sand, and they are extremely strong.

Wei Ming looked at the vibrant Suosuo forest on the periphery of millions of acres of sandy land, although it was still short and sparse, but it was standing tall to protect the "oasis" in the inner perimeter, it felt really, there was no way to describe it in words, anyway, it was very proud.

Is it bitter to control desertification?

It's really very bitter!

Wei Ming has been shaken several times to be accompanied by flying sand all day long, and there is no way to find a girlfriend, sometimes as long as he sees the golden desert, he feels that there is no hope in life.

But in the evening, when I sat on the sand dunes, looked up at the night sky, I saw a clear night, without a single cloud of clouds, and the stars were shining, and a few of them were exceptionally bright, twinkling and flashing, and reflected in the pupils...... It's rare to see such a real starry sky in a bustling and noisy city.

During the day, I saw young or old people watering green dreams with their actions to witness the change of the desert. In the 1 million mu Tengger Sand area, under the obstruction of grass squares, the wind and sand activities are gradually declining; the vegetation in the desert has turned new green, and the trees have revealed new branches; the weather is clear, and all kinds of birds fly to spend the summer from time to time, and everything is thriving.

Wei Ming suddenly felt that if he could proudly say to his children and grandchildren in the future, "I think back then, I was also a pioneer in the northwest to control desertification", which seemed quite interesting.
