Abstract
The invention relates to the field of compound fertilizers, in particular to a high-efficiency slow-release compound fertilizer containing Crotalaria pallid. The fertilizer is prepared from the following raw materials by weight part: 10-15 of 1250-2000 mesh diatomite, 10-12 of calcium carbonate, 6-8 of borax, 2-3 of magnesium ascorbyl phosphate, 8-10 of disodium hydrogen phosphate, 5-6 of pyracetic acid, 10-12 of potassium bitartrate, 20-22 of urea, 25-28 of diammonium phosphate, 12-15 of crop leftover, 3-5 of plasma protein powder, 1-3 of Crotalaria pallid fine powder, 4-5 of potassium alginate, 2-4 of stearic acid, 10-12 of gelatin, 1-3 of Vaseline, 1-2 of Tween 80, 2-4 of medical stone powder, 6-8 of polymeric ferric silicate sulfate, and 4-5 of an assistant. The compound fertilizer provided by the invention utilizes diatomite and a coating agent with good slow release ability to form dual cladding on the multielement nutrients, so that the nutrients are difficult to lose, and the fertilizer efficiency can be more lasting. The Crotalaria pallid fine powder in the coating agent has certain insecticidal and antibacterial ability, provides good growing environment for crop roots, and does not destroy the soil ecological environment. The fertilizer provided by the invention can significantly improve the crop yield and quality and enhance economic benefits.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to a high-efficiency slow-release compound fertilizer containing pig dung bean. 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 fertilizers.
