Problems solved by technology

However, the existing slow-release compound fertilizers still have certain shortcomings, mainly in that the nutrient ratio is relatively fixed, and it is difficult to meet the different needs of various soils and various crops; the slow-release effect is not satisfactory, and does not match the growth needs of crops , thereby reducing fertilizer efficiency, affecting crop growth, resulting in reduced production and income

Abstract

The invention relates to the field of compound fertilizers, and particularly relates to a slow-release compound fertilizer containing natural worm-expelling components. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of kieselguhr of 1250-2000 meshes, 10-12 parts of potassium sorbate, 16-19 parts of ammonium dihydrogen phosphate, 4-5 parts of magnesium chloride, 10-12 parts of sodium pyrophosphate, 22-23 parts of well-rotted farmyard manure, 6-8 parts of dried tempeh fine powder, 4-6 parts of formosan lattuce herb leaf and stem, 5-6 parts of Tephrosia purpurea stem and leaf, 4-5 parts of burdock dreg powder, 1-3 parts of starch aluminum octenylsuccinate, 1-2 parts of potassium persulfate, 10-12 parts of acrylamide, 1-2 parts of negative ion powder, 2-4 parts of medical stone powder, 6-8 parts of polymeric ferric silicate sulfate and 4-5 parts of assistant. According to the invention, the compound fertilizer formula has wide raw material sources and multiple nutrients; slurry of the formosan lattuce herb leaf and stem and the Tephrosia purpurea stem and leaf contains natural worm-expelling components, so that worms and ants can be prevented from nibbling the fertilizer; and by technically using the kieselguhr and the slow-release coating agent containing the negative ion powder, the nutrients are doubly coated, so that the nutrients are less prone to loss, and the fertilizer efficiency can last longer. In practical application, the compound fertilizer can obviously improve the yield and quality of crops and increase economic benefits.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a slow-release compound fertilizer containing natural insect repelling ingredients. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilize...
