Compound fertilizer for corn planting and preparation method thereof

Abstract

The invention discloses a compound fertilizer for corn planting, which consists of the following raw materials in parts by weight: 26-38 parts of plant ash, 51-69 parts of livestock and poultry excrement, 10-17 parts of Chinese herbal medicines, 3-7 parts of ground phosphate rock, 2-6 parts of bone powder, 6-12 parts of urea, 4-9 parts of potassium chloride, 2-5 parts of boric acid, 1-7 parts of amino acid, and 1-6 parts of calcium magnesium phosphate fertilizer. The prepared corn fertilizer has good fertilizer efficiency, strong pertinence, and fast nutrient absorption, and the utilization rate of the chemical fertilizer can be improved, the growth of a root system at a seedling stage is promoted, the viscosity of cell protoplasm can be improved, and the growth and development of crops are promoted. A variety of trace elements can not only promote the growth of seedlings, but also increase the number of grains in the later stage, so as to improve yield and quality. A fertilizer preparation method of the invention is simple and feasible, and the economic benefit is remarkable. With the fertilizer, soil acidity and alkalinity does not be disturbed, soil fertility can be further increased, and economic benefits are created for farmers.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a compound fertilizer for corn planting and a preparation method thereof. Background technique [0002] With the continuous increase of human demand for food and the continuous consumption of natural resources, the area of ​​arable land available to humans is continuously decreasing, and the fertilizer resources and raw materials that can be mined and synthesized are continuously decreasing, making humans need to produce more per unit area of ​​arable land. crops or food products. [0003] Maize is an annual herbaceous plant of the Poaceae Maize genus. Aliases: maize, stick, corn, corn, corn, corn, pearl rice, bract reed, big water millet, Chaoshan dialect is called young rice kernel, Cantonese is called corn, and Hokkien is called fanmai. Culms erect, usually unbranched, with aerial strut roots at base nodes. Leaf sheath with transverse veins; ligule membranous,...

Problems solved by technology

[0004] High-yield corn requires rich organic matter and mineral raw materials. In order to increase corn yields, many farmers choose to apply heavy fertilizers or simply apply urea. The nutritional components obtained are relatively simple, which cannot meet the nutritional supply needs of the entire corn plant, and adversely affect the growth and yield of corn
