Problems solved by technology

[0002] With the development of science and technology, the types of fertilization of cowpea have also undergone great changes. In many areas, in order to increase production, the application of organic fertilizers has decreased, but more and more chemical fertilizers have been used, resulting in a decrease in the utilization rate of chemical fertilizers and a decline in soil organic matter. If sufficient nutrients are not obtained, it will seriously affect the yield and quality of cowpea, reduce the income of growers, and is not conducive to sustainable development

Abstract

The invention discloses a chemical fertilizer for cowpea and a preparation method of the chemical fertilizer. The chemical fertilizer comprises the following components in parts by weight: 16-18 parts of a nitrogen fertilizer, 10-12 parts of a phosphatic fertilizer, 10-12 parts of a potassic fertilizer, 10-20 parts of chitin, 20-30 parts of a seaweed element, 80-100 parts of fermented cow dung, 3-5 parts of diammonium phosphate, 1-3 parts of humic acid, 20-30 parts of plant ash, 40-60 parts of manioc waste and 20-30 parts of vinasse. The special fertilizer for cowpea disclosed by the invention accords with the cowpea absorption rule, and is customized with a clear goal; the product quality can be significantly improved; and compared with an ordinary phosphatic fertilizer, the chemical fertilizer has the advantages that the yield and quality of cowpea are increased, and the fruiting period is prolonged.

Description

technical field [0001] The invention relates to a plant fertilizer, in particular to a cowpea chemical fertilizer and a preparation method thereof. Background technique [0002] With the development of science and technology, the types of fertilization of cowpea have also undergone great changes. In many areas, in order to increase production, the application of organic fertilizers has decreased, but more and more chemical fertilizers have been used, resulting in a decrease in the utilization rate of chemical fertilizers and a decline in soil organic matter. If sufficient nutrients are not obtained, it will seriously affect the yield and quality of cowpea, reduce the income of growers, and be unfavorable for sustainable development. Contents of the invention [0003] The invention provides a cowpea chemical fertilizer and a preparation method thereof. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A cowpea...
