Preparation method of composite biological bacterial fertilizer

Abstract

The invention relates to the technical field of biological bacterial fertilizer, in particular to a preparation method of composite biological bacterial fertilizer. By the biological bacterial fertilizer produced according to the preparation method, influences on the ecology of orchards can be reduced, the quality and taste of produced fruits are improved, and the planting cost is reduced. The preparation method includes the following steps: (1) preparation of raw materials: taking straw and mushroom dregs as main materials, cutting the straw into small pieces of 1-1.5 cm, soaking the straw in water for 10-12 hours, fishing out the straw for standby use, dispersing the mushroom dregs for standby use, taking livestock feces and plant ash as auxiliary materials, adding the plant ash to the livestock feces, and carrying out homogenization for standby use; (2) mixed fermentation: fully and uniformly mixing the homogenized plant ash and livestock feces with the straw and the mushroom dregs, adding EM, performing composting after uniform mixing, and performing fermentation at the temperature of 30-35 DEG C for 24-30 days; (3) aeration treatment; (4) solid-liquid separation; (5) preparation of composite liquid fertilizer; and (6) preparation of composite solid fertilizer.

Description

technical field [0001] The invention relates to the technical field of biological bacterial fertilizer, in particular to a preparation method of compound biological bacterial fertilizer. Background technique [0002] Cherry is the collective name for some plants of the genus Prunus, including the subgenus Prunus, subgenus Sour Cherry, subgenus Osmanthus, etc. Cherry pearls and cherries belong to the category of cherries. Because of their slightly different taste and shape, the names are The difference is that cherries can be eaten as fruits. The appearance is bright, crystal and beautiful, red like agate, yellow like fat, the fruit is rich in sugar, protein, vitamins and calcium, iron, phosphorus, potassium and other elements. The iron content of cherries is relatively high. High, the iron content per hectogram of cherries is as high as 59 mg, ranking first in fruits, so cherries can relieve anemia, the content of vitamin A in cherries is 4-5 times more than that of grapes, ...

Problems solved by technology

[0003] During the planting process of existing fruit trees such as cherries, cherry pearls, and cherries, various compound fertilizers are generally used to fertilize the fruit trees to supplement the nutrients of the fruit trees. However, the nutrient ratio of the compound fertilizers purchased on the market is fixed. When fertilizing fruit trees with nutrient supplements, it is very easy to cause the ecological instability of the orchard, and it will also cause the taste of the grown fruits to be poor. At the same time, the planting cost of this method is relatively high.
