Method for applying astragalus sinicus to no-tillage direct seeding of single-season rice

Abstract

The invention relates to a method for applying astragalus sinicus to no-tillage direct seeding of single-season rice. The method comprises the following steps of a, mechanical harvesting of astragalus sinicus: completely draining water in a rice field till a harvester can operate in the rice field when 75% astragalus sinicus pods of the whole rice field completely turn black; b, preparation of the rice field: firstly sowing and spreading straw-decomposing inoculants over accumulated straws of the astragalus sinicus, secondly irrigating the rice field till the water level is higher than the surface of the rice field; c, seed reserving of astragalus sinicus field and direct seeding of single-season rice: after keeping the water level of the rice field higher than the surface of the rice field for 2-3 days, seeding, accelerating germination of rice seeds, and when 80% rice grows two leaves and one core, irrigating shallow water and applying base fertilizer; d, management of the rice field: when rice plants grow three leaves and one core, spraying paclobutrazol, simultaneously applying urea in per mu rice field for topdressing, and after seeding for 30-40 days, spraying agroxone. According to the method provided by the invention, a series of problems that seeds in production and utilization of the astragalus sinicus in the south rice planting areas are in short, the seed harvesting of the astragalus sinicus and the utilization of the astragalus sinicus as green fertilizer cannot be compatible, how the yield of the direct seeding of single-season rice is obtained, and the like are solved, and the direct promotion function on re-popular green manure development and rice simple high-yield cultivation in country is carried out.

Description

technical field [0001] The invention relates to a method for applying milk vetch to no-tillage direct seeding of one-crop rice. Background technique [0002] Milk vetch is the main green manure crop in southern paddy fields. It has a long history of cultivation in southern paddy fields and plays a very important role in improving the soil quality and soil fertility of southern paddy fields in my country. In the traditional method of saving milk vetch seeds, the method of harvesting generally adopts manual methods to mow down milk vetch, and the straw after threshing is burned or removed. This method not only does not really achieve the effect of planting green manure and raising land, but also greatly wastes resources and pollute the environment. However, due to the stubble of milk vetch, it is more difficult to plow the rice fields after the seeds are left. [0003] In recent years, the planting area of ​​one-crop rice has increased rapidly. With the successful breeding o...
