Problems solved by technology

However, in the existing studies, most of the foliar fertilizers used are conventional water-soluble fertilizers, and there is no matching foliar fertilizer based on the performance of the one-time basal slow-release fertilizer for the double cropping anniversary of continuous cropping of cotton and rapeseed and the growth and development of cotton and rapeseed. Water-soluble fertilizer, there is no package fertilizer suitable for simplified fertilization in reduced amounts for the anniversary of continuous cropping of cotton and rapeseed

Abstract

The invention discloses a package fertilizer for annual simplified and reduced fertilization of continuous double cropping of cotton and rape. The package fertilizer comprises a base fertilizer which is applied at the same time with seed sowing at one time and a water-soluble fertilizer for foliage spraying in seedling and bud stages-initial flowering stage, blossing and boll-forming stages and rape seedling stage-stem elongation stage, and flowering stage, wherein the base fertilizer which is applied at the same time with the seed sowing at one time comprise the following effective elements based on pure nutrients in percentage by weight: 16-24% of N, 5-8% of P2O5, 15-25% of K2O, and 3-5% of S; a water-soluble fertilizer formula comprise the following effective elements based on pure nutrients: B, Zn, N, P2O5, K2O, amino acid, humic acid, and oligosaccharins. The package fertilizer provided by the invention can effectively ensure the nutrient demands of the cotton and the rape throughout the growth period, and has the functions of preventing diseases, preventing boll abscission, preventing rotten bolls, resisting high temperature and the like; the fertilization procedure is simplified; the use amount of chemical fertilizers is reduced; fertilizer utilization rate and fertilization benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a set fertilizer for simplified and reduced fertilization on the anniversary of double cropping of cotton and rapeseed. Background technique [0002] Cotton and rapeseed are important economic crops in my country. The Yangtze River Basin is the dominant cotton and rapeseed production area in my country. Cotton production areas and rapeseed production areas are highly overlapped. Continuous cropping of cotton and rapeseed is the main planting system of cotton and rapeseed in this region. In recent years, major changes have taken place in the agricultural production situation. With the acceleration of industrialization, urbanization and agricultural modernization, a large number of rural laborers have transferred to industry and the tertiary industry. The number of laborers engaged in agricultural production has decreased sharply, and the cost has risen sharply. Fie...
