Production process of biological organic fertilizer with purplestem eupatorium

Abstract

The preparation method of eupatorium coelectinum biological organic fertilizer includes the following steps: rought pulverizing fresh eupatorium coelectinum; adding the solid microbial detoxication agent soaked with hot water according to the weight ratio of 0.3-0.7% into the above-mentioned obtained rough-pulverized wet material, and uniformly mixing them; making the mixed wet material undergo the process of heap fermentation, after its temp. is up to 40-50 deg.C, drying material, making the water content of said material be below 13%, finally pulverizing said material to obtain the invented biological organic fertilizer. Said biological organic fertilizer can be used in field crops instead of nitrogen fertilizer, possesses obvious effect of increasing yield of crops, and can reduce nitrate and nitrite content in the vegetable.

Description

[0001] Field [0002] The invention relates to the technical field of preparation methods of biological organic fertilizers, and mainly uses Eupatorium adenophorum as raw materials to prepare biological organic fertilizers. Background technique [0003] Eupatorium adenophorum Spreng (Eupatorium adenophorum Spreng) is a plant belonging to the genus Eupatorium of the Compositae family. It is native to Mexico and Costa Rica in Central America. It is now widely distributed in more than 30 countries in Asia, Australia, the United States, and the Galina Islands. Tropical areas are a worldwide malignant weed. Eupatorium adenophorum was introduced into my country’s Yunnan Province from Myanmar and Laos in the 1940s. Due to its large population, strong fecundity and rapid growth and spread, it spreads from southwest to northeast at a speed of 10-30 kilometers every year. Spread to Guizhou, Sichuan, Guangxi and other provinces. Eupatorium adenophorum currently has an area of ​​25.8 million h...

Problems solved by technology

Because Eupatorium adenophorum contains toxic components, using it as fertilizer will have adverse effects on the growth and development of seeds

At present, there is only one report about using Eupatorium adenophorum to make fertilizer, that is, dig a pit in the field, put the harvested Eupatorium adenophorum into the pit and fill it with water to let it ferment naturally, and then put it out after it is decomposed Applied to the farmland as fertilizer, the fertilizer prepared by this method not only destroys the protein and other nutrients contained in Eupatorium adenophorum itself, but also volatilizes the ammonia produced into the air, polluting the environment

Fertilizers are not very efficient and do not remove the toxic components in Eupatorium adenophorum
