| titleOfInvention | Water retention and slow release type biological compound fertilizer and preparation method thereof |
| abstract | The invention relates to a water retention and slow release type biological compound fertilizer and a preparation method thereof. The preparation method comprises the following steps: taking crylic acid, acrylamide, sodium bentonite and urea as raw materials, potassium persulfate as an initiator, N,N-methylene bisacrylamide as a cross-linking agent and Span 60 as a dispersing agent, preparing a water-retention and slow release type fertilizer by adopting a chemical synthesis method, absorbing a functional microbial strain by using the water retention and slow release type fertilizer, drying at a temperature of 40 DEG C and crushing to obtain a product. The water retention and slow release type biological compound fertilizer and the preparation method thereof have the benefits that the absorption rate of distilled water is larger than 700 g/g. The absorption rate of saline solution is larger than 150 g/g, the nitrogen content is higher than 15 percent, the early nitrogen release rate is less than 15 percent, the accumulative release rate within 28 days is less than 80 percent, the accumulative release rate during the nutrient release period is larger than 80 percent, and the effective number of living bacterium after the storage for six months is above 3*107 cfu/g; the germination rate and the seedling rate of seeds can be obviously improved; the water retention and slow release type biological compound fertilizer has the advantages of environmental friendliness, high convenience for application, stable performance and the like; the effects of saving the agricultural water and improving the fertilizer efficiency can be effectively realized; the application prospect is wide. |
