Method for preparing bio-organic fertilizer by utilizing eupatorium adenophorum

Abstract

The invention discloses a method for preparing a bio-organic fertilizer by utilizing eupatorium adenophorum, and in particular provides a method for preparing a bio-organic fertilizer by using the eupatorium adenophorum as the main raw material, wherein the bio-organic fertilizer can kill eupatorium adenophorum seeds and eliminate poisonous components. The method comprises the following steps of: (1) crushing eupatorium adenophorum straws into powder; (2) mixing the crushed powder with high-temperature microbial strains, adding clear water, and then uniformly stirring the prepared mixed material; (3) stacking the stirred mixed material to be stripped, and carrying out aerobic fermentation for promoting the composting of the mixed material; and turning the stack once at a periodic interval to improve the ventilation condition in the stack; (4) maintaining the temperature of the stack of the mixed material over 58 DEG C; and (5) drying the mixed material after the stack of the mixed material ferments for the set time. By using the method, allelopathic effect active ingredients in the eupatorium adenophorum raw material are controlled, the eupatorium adenophorum seeds in the raw material are killed, and the produced fertilizer has nontoxicity, a good fertilizer effect and low production cost.

Description

technical field [0001] The invention relates to a method for bio-organic fertilizer, in particular to a method for preparing bio-organic fertilizer by using Eupatorium adenophorum. Background technique [0002] Eupatorium adenophora (Ageratina adenophora) is a perennial subshrub of Compositae, native to the Americas from Mexico to Costa Rica. Eupatorium adenophorum has strong fecundity and adaptability, and can grow in arid and barren barren slopes, walls, rock ridges, rock crevices, etc., and spreads extremely fast. Moreover, where Eupatorium adenophorum goes, no grass grows, cattle and sheep are poisoned, which seriously damages the local vegetation community structure, affects the local ecological environment, garden landscape and agricultural production, and is the "killer" and "number one invasive plant in the plant world". ". Eupatorium adenophorum was introduced into Lincang, Yunnan Province from Myanmar in the 1940s, and is now widely distributed in various provinc...

Problems solved by technology

Experiments have shown that the lethal temperature of Eupatorium adenophorum seeds is 58°C, which is higher than the fermentation temperature of these low-temperature bacteria. Therefore, the above method cannot kill the seeds in Eupatorium adenophorum materials by the temperature of fermentation

When harvesting Eupatorium adenophorum materials, it is difficult to completely avoid the mixing of seeds. Then, the finished organic fertilizer may contain Eupatorium adenophorum seeds with germination activity. s consequence

[0007] (2) The above method does not detect the toxic components in the finished product, so it is still unknown whether the finished organic fertilizer contains allelopathic active ingredients and whether it will inhibit the growth of crops

[0008] (3) The fermented material in the above method is mainly Eupatorium adenophorum straw, which has low organic matter and nitrogen content. Experiments have proved that the fermentation maturity of materials with low organic matter and nitrogen content is lower than that of mixed materials with high organic matter and nitrogen content. , then, in the case of low organic matter and nitrogen content and low degree of decomposition, the fertilizer efficiency of the finished organic fertilizer may not be ideal

[0009] (4) The finished product obtained by the above method is a powdery organic fertilizer. During the crushing, transportation and application process, dust is easily generated, causing air pollution. If toxic components remain in the finished product, the dust produced is toxic dust, which pollutes the air. to a greater extent

Moreover, in the production process, secondary crushing is required, the air pollution is more serious, and the cost will also increase

In addition, after adding inorganic ingredients, it is easy to absorb moisture and agglomerate, which will affect the fertilizer efficiency
