Problems solved by technology

[0004] 1. The ratio of the main nutrient elements in the fertilizer is not reasonable, and the utilization rate of the fertilizer is low;
[0005] 2. Low utilization rate of fertilizer, waste of resources and pollution of the environment;
[0006] 3. The cost of manufacturing sulfur-based compound fertilizers is high, resulting in high fertilizer prices and increasing the economic burden on farmers;
[0007] 4. Long-term large-scale use of fertilizers will lead to deterioration of soil physical and chemical properties;
[0008] 5. Fertilizers cannot release nutrients slowly, and the ratio of nutrients is not reasonable, and the matching of trace elements is not appropriate, which restricts the yield and quality of cotton

Abstract

The invention provides a cotton planting slow release fertilizer. The cotton planting slow release fertilizer comprises inner-layer slow release fertilizer particles and an outer-layer slow release fertilizer envelope. The inner-layer slow release fertilizer particles are prepared from, by weight, 20-30 parts of urea, 10-20 parts of potassium chloride, 10-20 parts of ammonium chloride, 10-25 parts of ammonium sulfate, 10-20 parts of superphosphate, 5-10 parts of zinc sulfate, 10-30 parts of mixed phosphate fertilizer, 4-7 parts of bentonite, 2-4 parts of bauxite powder, 5-10 parts of borax, 2-10 parts of zinc humate, 2-8 parts of boron humate, 1-5 parts of calcium humate, 1-4 parts of magnesium humate and 1-2 parts of compound sodium nitrophenolate. The cotton planting slow release fertilizer is high in fertilizer efficiency utilization rate and low in cost, soil physical-chemical properties can be improved, nutrition supply is comprehensive and balanced, and nutrients are released coordinately and lastingly.

Description

technical field [0001] The invention relates to the technical field of cotton planting, in particular to a slow-release fertilizer for cotton planting. Background technique [0002] Cotton is an important economic crop and plays an important role in people's livelihood and national economy. Effective use of limited land resources to improve the yield and quality of cotton crops is the direction and eternal subject of people's efforts. Cotton is a kind of full-nutrition deep-rooted crop, which requires a large amount of fertilizer during the growth period. The growth and development of cotton needs to absorb more than 20 kinds of nutrients, mainly including nitrogen, phosphorus, and potassium as three major elements; the essential elements of cotton are calcium, magnesium, sulfur, chlorine, and trace elements such as boron, zinc, manganese, Iron, Copper, Molybdenum and Chlorine. These nutrients mainly come from fertilizers provided through the soil. [0003] There are fol...
