Description

Technical field [0001] The invention relates to the application of crops, in particular to the application of a new rape variety as green manure. Background technique [0002] Green manure is one of the important sources of biological nitrogen and organic fertilizer in traditional agriculture in my country, and its cultivation and utilization have important status and significance. The 1970s was the peak period of green manure planting in my country. The planting area reached more than 200 million mu. Afterwards, the green manure area decreased year by year due to factors such as the adjustment of the planting industry structure, the reform of the crop rotation system, the increase of the multiple crop index, and the substantial increase in the amount of fertilizer. However, due to the large-scale application of chemical fertilizers, the amount of organic fertilizers has been greatly reduced, which has led to the deterioration of the physical and chemical properties of the soil, ...

Problems solved by technology

However, in modern agriculture, green manure has less and less significance as a source of crop nutrients, but it has very important strategic significance in improving soil, fertilizing soil, ensuring high-quality and stable crop yields, developing sustainable agriculture, and protecting the ecological environment.

[0003] At present, the green manures used in production mainly include leguminous crops such as milk vetch and cruciferous crops such as common rapeseed, which generally have defects such as narrow sowing period, slow growth, small biomass, poor adaptability, and high seed cost. How to select and breed a kind of green manure that more meets the requirements of modern agriculture is of great significance to those skilled in the art
