A method of using earthworm fungus to improve soil nitrogen nutrient and promote fast-growing trees

Abstract

The invention discloses a method for utilizing earthworm fungicide for improving soil nitrogen nutrients to achieve growth promotion of fast growing forest, and belongs to the technical field of forestry ecology. The method has the advantages that the effect is good, wherein the content of total nitrogen and effective nitrogen in soil is remarkably increased within one year; the content of nitrogen is greatly improved, wherein accumulation of total nitrogen and effective nitrogen in soil has the remarkable synergistic interaction effect; multiple purposes are achieved at the same time, wherein due to application of pig manure, biogas slurry combined with earthworms and fungicide, the content of effective nitrogen in soil can be rapidly increased, the nitrogen fertility stability can be rapidly improved, growth of fast growing forest can be promoted, the branch diameter, the plant height and the crown breadth are improved by 1.7 times, 1.3 times and 5.1 times compared with CK, and livestock excrement pollution is digested and saved. A research shows that due to application of earthworms and fungicide, the decomposition rate of pig manure in soil can be increased, so that the soil nitrogen content is increased; some nitrogen in air which cannot be utilized by plants can be converted into available nitrogen elements; earthworms and fungicide contain carbon and nitrogen nutrients, and due to the combined application, the content of nitrogen in soil can be increased.

Description

technical field [0001] The invention belongs to the technical field of forestry ecology, and in particular relates to a method for increasing soil nitrogen nutrient and promoting fast-growing trees by using earthworm fungus agent. Background technique [0002] In recent years, the development of the breeding industry has brought a large amount of livestock and poultry manure. In 2015, the production of livestock and poultry manure in my country's large-scale breeding industry reached 3.26 billion tons. Livestock and poultry manure contains a lot of nutrients such as N and P. Using it as an agricultural organic fertilizer can not only fertilize the soil, provide nutrients needed for plant growth, increase crop yield, but also dispose of a large amount of livestock and poultry manure and solve environmental pollution. question. [0003] Nitrogen is one of the essential elements for plant growth, one of the most important elements that constitute life, and an important indicat...

AI Technical Summary

Problems solved by technology

[0008] At present, domestic and foreign technology research and development are mostly focused on the preparation of organic fertilizers (earthworms, bacterial agents, enzymes, etc.), combined application of organic fertilizers and chemical fertilizers, etc. to increase the nitrogen content of farmland soil and enhance soil fertility. There is almost no method to accelerate the transformation of pig manure nitrogen (organic nitrogen) by applying biogas slurry, earthworms, and bacterial agents

And the existing technology generally has the disadvantages of slow effect, cumbersome preparation process, complicated formula, etc.
