Preparing method of walnut green husk dreg organic fertilizer

Abstract

The invention relates to a preparing method of a walnut green husk dreg organic fertilizer. The preparing method comprises the steps of preparing the walnut green husk dreg organic fertilizer by adopting walnut green husk dregs, edible fungus dregs and plant ash as main ingredients, carrying out inoculation of a microorganism strain for fermentation and the like. The walnut green husk dreg organic fertilizer contains no poultry and livestock manure, avoids side effects of seeding blight, root blight, diseases and pests and the like caused by applying excrement and urine inorganic fertilizer of livestock and poultry, reasonably and effectively solves the problem of pollution of the walnut green husk and the edible fungus dregs to environment, and turns waste into wealth; the walnut green husk dreg organic fertilizer further has high potassium content, resistance to diseases and pests of fruit trees is strengthened after the use of the fertilizer, the yield of the fruit trees is increased, the fruit quality is sharply improved, and economic benefits are significantly increased.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, and relates to a preparation method of walnut green peel dregs organic fertilizer. [0002] technical background [0003] At present, my country's walnut cultivation area and output rank first in the world. The total walnut output has increased steadily year by year, and the pollution of green peels has become increasingly serious (the output of green peels is 4-5 times that of dried walnuts). Walnut green peels contain a variety of physiologically active components, mainly containing volatile oil. , fatty acids, walnut polysaccharides, juglone and its derivatives and other chemical components, containing secondary substances such as phenols, flavonoids, coumarins, terpenes, steroids and organic acids, etc., have good pesticide activity. The lignin content in walnut green skin is high, and the degradation rate is very slow in nature, and it is not easy to rot. Randomly stacked walnut...

AI Technical Summary

Problems solved by technology

[0004] At present, the research on walnut green peel is mainly focused on extracting effective active substances, and most of them use common methods such as solvent extraction, vacuum distillation, cold soaking and heat reflux. These methods have the disadvantages of low extraction rate and high energy consumption. There is less research and technology for overall treatment, and less practice of reusing it as resources, which cannot fundamentally solve the pollution problem

Although Liang Shujuan and others use walnut green skin dregs to make bio-organic fertilizers, the raw material ratio is mainly animal manure, which has many impurities, great deviations in purity, and extremely unstable content, which cannot guarantee the nutrient content and effect of application.

In addition, livestock and poultry manure organic fertilizers contain heavy salt, which is easy to salinize the soil. Increasing the soil salt concentration will increase the critical point of the fertilizer effect of nutrients on crops, and increase the amount of fertilizer. In severe cases, it will cause the seeds not to germinate and burn the seedlings. , burn roots; acidic livestock and poultry manure organic fertilizer is prone to pathogenic bacteria and must be neutralized with lime to cause soil compaction; the nitrogen in livestock and poultry manure is mainly in the form of uric acid, and uric acid cannot be directly absorbed and utilized by crops. When it decomposes in the soil, it consumes a lot of oxygen and releases carbon dioxide gas, so it is easy to damage the roots of crops; livestock and poultry manure itself carries many germs and eggs (such as Bacillus, Escherichia coli, fungi of more than ten genera and some parasitic Insects, etc.), easy to cause diseases and insect pests; some livestock and poultry manures still have the problem of excessive trace element content
