Wujiaqu, Xinjiang, December 22 (Xinhua) -- The land here "eats" the "probiotics" of space
**Reporter Li Xin.
The use of chemical fertilizers and pesticides is increasing year by year, and crop growth is not as good as year by year. "The problem that has plagued Zhang Hongfang, the head of the Xinhu Farm Agricultural Development Service Center for many years, has been solved by a space microbial agent.
Recently, the reporter came to Wujiaqu City, the Sixth Division of the Xinjiang Production and Construction Corps, to decrypt the space "probiotics" that the land "eats" here.
Wujiaqu City of the Sixth Division is a large agricultural city, with more than 280 acres of cultivated land, and the long-term use of pesticides and fertilizers has caused problems such as land compaction and acidification, serious soil pollution, and agricultural non-point source pollution.
The strains we use have been carried into space by the 'Shenzhou' spacecraft, using cosmic rays and other mutagenic factors in space to verify the stability of the strains, and through a variety of technical means such as high temperature resistance, salt and alkali resistance, radiation resistance, etc., we have cultivated excellent microbial flora, which has the characteristics of improving soil, reducing drugs, and protecting seedlings with disease resistance. Xinjiang Aerospace Mega Technology *** hereinafter referred to as Xinjiang Aerospace Mega) general manager Zhou Hailong said.
In order to promote the healthy and sustainable development of the ecological environment and modern agriculture, Wujiaqu has introduced this high-tech enterprise.

After the use of microbial agents, cotton emerged early, Verticillium wilt was inhibited, and pests and diseases were reduced. Zhang Hongfang, who has served agriculture for many years, said that through comparison, it was found that microbial agents can effectively remediate contaminated soil.
Similarly, Yan Jun of Qitai Farm of the Sixth Division will plant a yield of 898 per mu in 202319 kilograms of wheat set a record for the highest yield in Xinjiang, and the microbial inoculant broke his traditional planting experience of "one crop and one flower, all rely on fertilizer". "After the use of microbial agents, the wheat has large ears, uniform grains, full size, and good growth. ”
In 2021, Xinjiang Aerospace Zhaofeng began to pilot 400 mu of cotton in the 101st regiment of Wujiaqushi City, with a cotton yield of 62 kg per mu and an increase of 0 in soil organic matter compared with the control group38g kg, the pH value was reduced by 029, the total salt amount was reduced by 66g/kg。The amount of nitrogen, phosphorus and potassium fertilizers was reduced by 42kg、2.2kg、1.9kg, pesticide spraying less than 3 times.
The control test proved that the microbial agent played a leading role in not reducing production and reducing the effect of drug reduction. Zhou Hailong said that compared with the common microbial agents on the market, the number of effective live bacteria exceeds 120 billion grams, which is 6 times that of other similar products, and can also reduce the amount of fertilizer and pesticides by 10% per mu of cultivated land, and the amount of pesticides is 20%, which is expected to save 111 yuan per mu of planting costs, which not only allows farmers to have a real income, but also protects the sustainable use of cultivated land.
Since 2022, the six divisions and five cities have taken the lead in promoting the application of microbial agents in major crops such as cotton, wheat, melons, fruits, and vegetables for about 1 million mu. After the experimental comparison, the pH value of the soil with microbial inoculants decreased by 0 on average29. The organic matter content increased by 0 compared with the control9g kg, the water-soluble salt decreased by 6 compared with the control6g/kg。
Long-term use can significantly improve soil aggregate structure, air permeability and water permeability, improve soil water and fertilizer retention capacity, improve drought resistance and stress resistance of crops, regulate the balance of crop vegetative growth and reproductive growth in both directions, promote crop rooting, growth, flowering and fruiting, and improve crop yield and quality. Wu Xinyuan, director of the Institute of Grain Cropping of the Xinjiang Academy of Agricultural Sciences, said that the use of microbial agents is not only because it can increase production and income, but more importantly, it can effectively improve soil quality.

On May 20, 2023, Xinjiang Aerospace Zhaofeng's R&D and production base with an annual output of 10,000 tons of effective bacteria, 120 billion grams, and 165 billion grams of microbial agents was put into operation. On October 30, the production base of compound microbial fertilizer with an annual output of 200,000 tons started.
Zhou Hailong said that in the future, the company will focus on promoting the application of space microbial bacteria in compound microbial fertilizers, fecal deodorization, garbage deodorization, household toilet deodorization, etc., and gradually replace traditional chemical fertilizers through "microbial bacteria + composite microbial fertilizers" to help agricultural carbon sequestration and emission reduction, soil improvement, cultivated land protection, and "feed" the land with more biological fertilizers.
