Problems solved by technology

At present, in the production of crops, there are still some unreasonable factors in the use of liquid fertilizers. Excessive pursuit of nitrogen, phosphorus and potassium required by crops, unreasonable fertilization and improper fertilization methods have led to low fertilizer utilization rates and crop nutritional imbalance. The quality has declined, and the soil properties of the cultivated land have deteriorated, seriously polluting the environment

Abstract

The invention relates to the technical field of fertilizers, in particular to a preparation method for a liquid fertilizer. The method comprises the following steps that S1, malt and spinach are crushed separately and then are uniformly mixed, distilled water is added, soaking is carried out, a pretreatment solution is added, and stirring is carried out at normal temperature so as to obtain a fermentation raw material, wherein the pretreatment solution is an alkaline solution; and S2, saccharomycetes is added into the fermentation raw material, anaerobic fermentation is carried out, filteringis carried out, and a filtrate is evaporated and concentrated so as to obtain the liquid fertilizer. The method has the advantages of being simple in process, safe and environmentally friendly, and the prepared liquid fertilizer has the advantages of being rich in nutrition, high in quality, long in fertilizer efficiency, high in nutrient utilization rate, capable of effectively promoting the cropgrowth and capable of increasing the crop yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a preparation method of liquid fertilizers. Background technique [0002] In the past, fertilization was done from the roots, and the nutrients were transported from the roots to the whole body of the crops; this effect is very slow, because the whole body of the crops can absorb nutrients, and liquid fertilizers take advantage of this, spraying the whole body of the crops, the crops absorb quickly, and are becoming more and more popular in various countries. of general concern. Liquid fertilizer is a typical high concentration fertilizer. Fertilizers are inevitably used in agricultural production, which is the protection of the land for planting crops and the need to obtain higher yields and higher quality crops. At present, in the production of crops, there are still some unreasonable factors in the use of liquid fertilizers. Excessive pursuit of nitrogen, phosphorus and ...
