Preparation method for high-calcium earthworm organic foliar fertilizer

Abstract

The invention relates to a preparation method for high-calcium earthworm organic foliar fertilizer. The preparation method comprises the following steps: 1) straw treatment: crushing straw, adding the crushed straw in an enclosed apparatus, adding ammonia water and carrying out microwave softening so as to obtain softened straw after completion of softening; 2) preparation of a culture matrix: mixing animal manure, the softened straw, an inoculum and active calcium filter residues in proportion and carrying out fermentation and decomposing so as to obtain the culture matrix for earthworms; 3) breeding management: flatly spreading the culture matrix on a culture bed, adding young earthworms and carrying out culture so as to obtain high-calcium earthworms and high-calcium earthworm manure; and 4) enzymatic hydrolysis of the earthworms: cleaning the earthworms with clear water, carrying out homogenization, carrying out enzymatic hydrolysis by using enzymes in the earthworms so as to obtain enzymatic hydrolysate, adding water extract of the high-calcium earthworm manure and an active calcium filtrate into the enzymatic hydrolysate, carrying out uniform mixing under stirring, and then carrying out disinfection and filtering so as to obtain the high-calcium earthworm organic foliar fertilizer. The high-calcium earthworm organic foliar fertilizer prepared by using the method has the characteristics of high content of active calcium, richness in diversified amino acids and mineral matters, etc.

Description

technical field [0001] The invention relates to a preparation method of foliage fertilizer, which belongs to the field of agricultural technology. Background technique [0002] Calcium is an essential element for life. For plants, calcium is an element that forms the cell wall. The intercellular layer of the cell wall is composed of calcium pectate. When calcium is deficient, the formation of the cell wall is hindered, affecting cell division, or cannot form New cell walls, such as calcium deficiency in grapes, will cause grape leaves to curl, fruit cracking, and aggravate fruit rot to a certain extent; calcium deficiency in tomatoes and peppers is prone to navel rot. Therefore, calcium is an irreplaceable structural element for plants. However, the form of calcium that plants can absorb from the soil is very small, and only young root tips can absorb calcium. Therefore, it is difficult to absorb and utilize calcium. In addition, calcium is mainly used in plants. Exist in s...

Problems solved by technology

Therefore, calcium is an irreplaceable structural element for plants. However, the form of calcium that plants can absorb from the soil is very small, and only young root tips can absorb calcium. Therefore, it is difficult to absorb and utilize calcium. In addition, calcium is mainly used in plants. Exist in stems and leaves and old leaves, because the mobility of calcium in plants is poor, and fruit trees need a lot of calcium in the fruit-hanging period, once calcium is lacking, it will cause malnutrition, decreased immunity, and susceptibility to various bacteria If you get sick, the quality of the fruit will decline, and the production will decrease in the coming year. By spraying calcium foliar fertilizer, it can play a role in timely calcium supplementation.
