Coated slow-release base fertilizer for improving yield of pomegranates

Abstract

The invention discloses a coated slow-release base fertilizer for improving the yield of pomegranates. The coated slow-release base fertilizer is composed of basic material particles and coating layers which coat the basic material particles. The basic material particles are prepared from, by weight, chicken manure, cakes and meal, humus, biogas slurry, traditional Chinese medicine residues, pimacol, polypeptide urea, ammonium sulfate-nitrate, a rare earth phosphate fertilizer, potassium sulphate, potassium chloride, sodium selenite, silica powder, zinc sulfate, a copper fertilizer, a manganese fertilizer, a molybdate fertilizer, sodium alginate, polyvinylpyrrolidone, a compound microorganism inoculant, oligosaccharins and corn cob residues. According to the coated slow-release base fertilizer for improving the yield of the pomegranates, nutrients are comprehensive, the slow-release performance is high, the nutrient releasing speed accords with the fertilizer-required rhythm of the pomegranates, the fertilizer utilization rate is high, improvement of the yield and quality of the pomegranates is facilitated, and the soil environment can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a coated slow-release base fertilizer for improving pomegranate yield. Background technique [0002] Pomegranate: sweet in nature and flavor, sour and astringent, warm, and has the effects of killing insects, astringent, astringent intestines, and stopping dysentery. Pomegranate fruit is rich in nutrition, and its vitamin C content is one or two times higher than that of apples and pears. It is a berry that is very popular among consumers. In the process of pomegranate planting, the base fertilizer plays an important role in the growth and development of pomegranate, but the current base fertilizer for pomegranate has insufficient nutrients, poor slow-release performance, nutrient release is inconsistent with the law of pomegranate fertilizer requirements, and the fertilizer utilization rate is low, which affects the yield and quality of pomegranate. It will have a certain i...

Problems solved by technology

In the process of pomegranate planting, the base fertilizer plays an important role in the growth and development of pomegranate, but the current base fertilizer for pomegranate has insufficient nutrients, poor slow-release performance, nutrient release is inconsistent with the law of pomegranate fertilizer requirements, and the fertilizer utilization rate is low, which affects the yield and quality of pomegranate. It will have a certain impact, and at the same time, it will easily deteriorate the soil environment, which is not conducive to the sustainable development of agriculture in our country.
