A few days ago, Wei Benhui, inventor of the new farming method "powder ridge technology" and a researcher at Guangxi Academy of Agricultural Sciences, put forward the idea that powder ridge can drive the "trilogy" of food and environmental security: first, to improve the production capacity of existing cultivated land through powder ridge. to achieve the relative security of food and environment The second is to develop "a new pole of agricultural growth of grain, meat, and fish" to increase grain, meat, and fish in saline-alkali land, grassland, and river water bodies; and third, to promote extensive popularization and form a "grain abundance, a better climate, and an ecologically pleasant". A new situation of more harmonious coexistence between human beings and nature.

This is Wei Benhui's self-propelled powder ridge machine recently developed by Guangxi Wufeng Machinery Co., Ltd. More than 100 sets have been popularized and ploughed on a large scale in Hainan, Guangdong, Yunnan, Guangxi and other places, and have been greatly welcomed by users. especially in Guangxi Chongzuo, guests and other sugarcane "double high" base users have a lot of "grab" machines, supply exceeds demand, put forward.

It is understood that over the past seven years, the "powder ridge technology" has been applied to 20 crops, including rice, corn, wheat, and sugarcane in 20 provinces. Without increasing the application of chemical fertilizers and pesticides, it can increase production by 10% per cent, improve quality by 5%, and double water retention.

Wei Benhui told reporters, "Powder ridge farming seems simple, but living soil, water conservation, oxygen enrichment, temperature increase, and light salt. The essence of science lies in: the amount of loose soil doubles, the amount of water and oxygen stored in the soil more than doubled, the availability of soil nutrients greatly increases, the structure of soil aggregates is good, and it is conducive to soil microbial activities and soil warming and light salt."

The secret of the yield increase, quality improvement and water conservation of the powder ridge is that the powder ridge mechanical spiral bit vertically enters the soil and deep rotary tillage, which can be deeply reclaimed and loosened at one time according to the needs of crop planting, and the tillage layer can be twice or more than that of tractor tillage. and does not disturb the soil layer. When the spiral bit cuts the soil at high speed, it produces instantaneous high temperature, coupled with the rapid entry of air oxygen in the process of rotary grinding and the action of soil enzymes, the nitrogen, phosphorus, potassium and other mineral elements in the soil are released, and the nutrient availability is increased by 10%. In this way, the soil is full of oxygen, which is more conducive to the activities of aerobic microorganisms and improves the utilization rate of fertilizer.

With regard to the first part of the powder ridge-driven "trilogy"-improving the production capacity of existing cultivated land and realizing the relative safety of food and the environment, Wei Benhui analyzed that at present, domestic agriculture is seriously short of water and is heavily polluted. If the powder ridge technology is popularized throughout the country, the production capacity of cultivated land can be increased by 150-200 million mu every year, and not only the increased grain production can feed 300 million people. Moreover, the amount of "chemicals" such as fertilizers and pesticides can be saved by 10%, 30%, and the storage of natural precipitation can be increased by 30 billion cubic meters.

Drive part II to develop "a new pole of agricultural growth in grain, meat and fish". According to Wei Benhui, China has 500 million mu of saline-alkali land, and if 1-200 million mu is transformed into normal fertile land, it can increase by 400kg to 80 billion kg of grain per mu. The "well shape", "five ring" and "full tillage" cultivation of the converted grassland is carried out by using the powder ridge technology, and the depth of the powder ridge is about 30 cm, so that it can activate the grassland soil and gather natural precipitation in the soil. it can not only maintain the original characteristics of the grassland, but also enrich grass and raise sheep and cattle, and increase considerable production of high-quality meat. Land, rivers, lakes and offshore water bodies are aquaculture resources that deserve the most attention in China's development and utilization, such as popularizing powder ridge technology, reducing the application of chemical fertilizers and pesticides by 20% and 30%, and vigorously controlling industrial and urban domestic sewage, the state has allocated special funds for fish fry breeding and release, so that fish and shrimp can reproduce naturally in rivers and water bodies, provide safe aquatic products, and increase the source of protein for the people.
