Problems solved by technology

However, the utilization rate of existing slow-release fertilizers is low, and the slow-release effect is slow and limited. At the same time, there is no research report on the preparation of specific slow-release fertilizers for specific crop varieties in the prior art. Yam slow-release fertilizer with absorption properties is very necessary

Abstract

The invention discloses a slow-release fertilizer for Chinese yam. The slow-release fertilizer is prepared form a film-coated material and fertilizer particles, wherein the film-coated material is prepared from the following raw materials in parts by weight: 30-70 parts of sodium alginate oligosaccharides, 5-10 parts of polyacrylamide, 3-8 parts of lignin, 1-5 parts of talcum powder, 0.1-0.5 part of glacial acetic acid, 0.05-0.2 part of ammonium persulfate and 0.02-0.1 part of an aid; and the fertilizer particles are prepared from the following raw materials in parts by weight: 50-100 parts of urea, 45-80 parts of potassium sulfate, 40-60 parts of calcium superphosphate, 25-40 parts of ammonium hydrogen carbonate, 20-40 parts of waste residue, 20-30 parts of humic acid, 15-25 parts of earthworm powder, 5-10 parts of chitosan, 5-10 parts of diatomite, 3-5 parts of microelements and 0.5-3 parts of biological bacteria. The invention further provides a preparation method of the slow-release fertilizer. The slow-release fertilizer has the beneficial effects that the utilization rate is high, a slow-release effect is moderate and stable, the loss rate of the fertilizer can be effectively reduced, and the yield of the Chinese yam can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers and fertilizer manufacturing, in particular to a Chinese yam slow-release fertilizer and a preparation method thereof. Background technique [0002] Huaishan, also known as yam, also known as yam and long taro, belongs to the family Dioscoreaceae, and is eaten with its plump tuberous root or cylindrical root. The root tuber contains 1.5% protein, 14.4% carbohydrate, and contains multivitamins and choline, etc., with high nutritional value. Yam is a perennial perennial vine. It likes warmth and is not cold-resistant. The root tubers start to germinate above 10°C, the stem and leaf growth is most suitable at 25°C~28°C, and the tuber expansion is fastest at 20°C~24°C. Huaishan grows extensively and is used both as medicine and vegetables, and the masses like to plant it. In terms of cultivation, Huaishan is the crop that is planted and harvested in the same year all the year round. Huaishan can...
