Abstract

The invention relates to the field of compound fertilizers, in particular to a green and antibacterial dual control slow release compound fertilizer. The fertilizer is prepared from the following raw materials by weight part: 10-15 of 1250-2000 mesh diatomite, 10-12 of borax, 4-6 of ammonium molybdate, 18-20 of urea, 22-25 of ammonium dihydrogen phosphate, 20-25 of ammonium bicarbonate, 12-15 of potassium nitrate, 10-12 of plant ash, 3-5 of Vaccinium bracteatum Thunb leaf, 16-18 of waste yeast slurry, 12-14 of livestock manure, 5-7 of soy sauce residue, 4-5 of yellow wine distilled grain, 10-12 of humus soil, 1-3 of Litsea cubeba oil, 6-8 of polyvinyl alcohol, 2-4 of puffed starch, 4-5 of acrylic acid, 0.1-0.2 of potassium permanganate, 2-4 of medical stone powder, 6-8 of polymeric ferric silicate sulfate, and 4-5 of an additive. The compound fertilizer provided by the invention has the characteristics of wide source and diversified nutrition. Technically, diatomite and a litsea cubeba oil containing slow release coating agent are employed to perform dual coating on the nutrients, the slow release effect is stable and lasting, the crop root growth environment is good, plant diseases and insect pests are difficult to occur, and the crop yield and quality are both enhanced. Thus, the fertilizer is an novel green slow release fertilizer with antibacterial and disease preventing efficacy.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a green antibacterial double-controlled slow-release compound fertilizer. 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. Howev...
