Problems solved by technology

A large number of scholars at home and abroad have shown that the combined application of organic fertilizers and chemical fertilizers and the application of fertilizer synergists and activators have achieved remarkable results in high-quality and high-yield rapeseed, improved soil fertility, and increased nutrient use efficiency. Most of them are the application of single technology on rapeseed
In addition, waterlogging is one of the important limiting factors for the growth of rapeseed in paddy fields, especially in the stubble area of ​​the southern three-cropping area. The interval between late rice harvest and rape sowing is short, resulting in insufficient drying time. Rapeseed has a serious waterlogging problem
[0004] Therefore, in view of the problems of large amount of chemical fertilizer application, low fertilizer utilization efficiency, and serious waterlogging in rapeseed cultivation areas, it is urgent to provide a fertilization method for rapeseed cultivation that can meet the needs of high yield, low consumption, and sustainable agricultural ecological environment in rapeseed cultivation areas.

Abstract

The invention relates to the technical field of agricultural planting, and discloses a seed fertilizer for reducing chemical fertilizer application and improving the efficiency for rapeseed and a fertilization method. The seed fertilizer includes, by mass, 40-60 parts of monoammonium phosphate, 20-40 parts of potassium nitrate, 5-15 parts of magnesium sulfate, 1-10 parts of ammonium pentaborate and 1-10 parts of calcium chloride. The fertilization method includes simultaneously performing deep application of a base fertilizer and surface application of the seed fertilizer, after ridging, ploughing for fermentation and ditching; then sowing seeds; and performing topdressing in a bolting period and a blooming period, wherein the base fertilizer includes an organic fertilizer and a compound fertilizer. The formula of the rapeseed seed fertilizer is optimized, and the fertilization method for rapeseed cultivation adopts deep application of the base fertilizer and surface application of theseed fertilizer, and therefore, the fertilizer utilization rate can be improved, seed germination is promoted, nutrient requirements on seed germination and seedling growth can be effectively met, the application amount of chemical fertilizers is reduced and the rapeseed yield is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a seed fertilizer and a fertilization method for reducing the application of rapeseed chemical fertilizers and increasing the efficiency. Background technique [0002] Rapeseed is mainly cultivated in winter and does not compete with other oil crops for land. At the same time, it also has a wide range of production adaptability. It can be planted in areas with one-year or more than one-year crops, especially in subtropical rice-growing areas in my country. Double or triple cropping of rice and rape can make full use of light, heat and soil resources. [0003] In order to pursue high yield, rapeseed cultivation areas often use chemical fertilizers irrationally, which not only results in low fertilizer utilization efficiency, but also causes serious harm to the environment. In recent years, researches on the rationalization of fertilization based on optimized environm...
