Biological organic fertilizer special for fruit trees and preparation method of biological organic fertilizer

Abstract

The invention relates to the technical field of biological organic fertilizers, in particular to a biological organic fertilizer special for fruit trees and a preparation method of the biological organic fertilizer. The growth demand of fruit trees of cherries, Chinese cherries, USA cherries and the like can be met, the influence on the ecological environment of an orchard can be reduced, the taste of grown fruits is improved, and the cost is reduced. The biological organic fertilizer is prepared from, by weight, 5-10 parts of a microbial composition, 3-4 parts of EM, 15-20 parts of mushroom dregs, 10-16 parts of plant ash, 170-195 parts of straw, 80-95 parts of livestock excrement, 17-22 parts of earthworm excrement and 2-4 parts of a water retaining agent. The preparation method of the biological organic fertilizer comprises the following steps of (1) mixing of the microbial composition; (2) straw pretreatment; (3) pretreatment of the livestock excrement and the earthworm excrement;(4) material mixing; (5) primary fermentation; (6) high-temperature thorough-decomposing treatment; (7) addition of the microbial composition; (8) after-fermentation; (9) prilling.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a special bio-organic fertilizer for fruit trees and a preparation method thereof. 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...

Problems solved by technology

[0003] During the planting process of fruit trees such as cherries, cherry blossoms, 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 and cannot be perfectly applied to The growth needs of fruit trees such as cherries, cherry blossoms, and cherries. When using compound fertilizers to supplement nutrients for fruit trees, it is very easy to cause ecological instability in the orchard, and the taste of the grown fruits is not good. At the same time, using this method Planting costs are higher
