Abstract

The invention belongs to the fertilizer field and particularly relates to microbial water-soluble fertilizer and a preparation method thereof. The microbial water-soluble fertilizer comprises a live microbial agent, potassium fulvic acid, amino acid, sucrose, cyclodextrin, humic acid, nutrient fertilizer, microelements, sodium lignin sulfonate and a surfactant. According to the microbial water-soluble fertilizer, the microbial agent is coated with cyclodextrin, then the is mixed with humic acid, the nutrient fertilizer and chelate microelements, and the problems that microbial fertilizer cannot be mixed with traditional fertilizer easily, is difficult to apply and the like are solved. The microbial water-soluble fertilizer is rich in nutrition and high in nutrient content, the added aminoacid, sucrose and microelements can increase the survival rate of beneficial active bacteria, the efficiency of the fertilizer is comprehensively played, the yield and quality of crops are improved, and the fertilizer can improve the soil environment and enhance the immunity of the crops after being used for a long time.

Description

technical field [0001] The invention belongs to the field of slow-release fertilizers, in particular to a microbial water-soluble fertilizer and a preparation method thereof. Background technique [0002] China is a large agricultural country. With the continuous development of agricultural technology, fertilizers are becoming more and more important in agriculture. However, the contribution rate of traditional chemical fertilizers to food growth is only 46.3%, and the application of large amounts of chemical fertilizers will also cause damage to the soil environment. pollute. Therefore, some new types of fertilizers have appeared on the market, among which water-soluble fertilizers have the widest application range. Water-soluble fertilizers are multi-component compound fertilizers that can be dissolved in water. The utilization rate is relatively high, realizing the integration of water and fertilizer, and achieving the effect of saving water, fertilizer and labor. [00...
