Problems solved by technology

[0003] Non-chemically synthesized nematode inhibitors are attracting more and more attention, but the cumbersome manufacturing process and high cost make the implementation of this work concept very difficult
At present, there have been reports about the use of large-scale fermentation equipment to make chicken manure into organic fertilizer liquid, but the pure chicken manure fermentation liquid does not have effective killing and inhibiting effects under low concentration conditions, and there is no such effect under the condition of drip irrigation and fertilization. Effective method for applying high-concentration chicken manure fermentation liquid
However, the residue in the high-concentration fermentation broth will seriously block the filter of the dropper system, and the flow rate of the fertilizer injection pump in the common large-scale wheel irrigation area can only account for 3-4% of the water flow rate of the main pipeline.

Embodiment 1

[0021] Example 1 Fermentation of fermentation broth

[0022] figure 1 Shows the implementation device structure of the fermentation broth fermentation process of the present invention, where the top three first-level tanks are reaction tanks for fermentation substrates, and the lower second-level and third-level tanks are only used for filtering debris and mixing Filtrate from three primary tanks. The water addition device is only set in the first-level pool, and no additional water is added to the second and third-level pools. After three-stage filtration, the filtrate can be applied to the field by drip irrigation through the first integrated water and fertilizer system.

[0023] The fermentation process is mainly carried out in a level 1 tank with a total volume of 1000m 3 The cube, made of concrete, is 16.0m long, 12.5m wide and 5.0m deep. The upper part of the pool is equipped with a water injection device, and the water source is river water. There is a sunshade above the ...

Abstract

The invention relates to the field of agricultural organic chemicals, and in particular relates to fermenting liquid with a nematode prevention effect. The fermenting liquid is prepared by the steps: mixing fresh chicken manure and molasses wastewater to obtain a fermenting substrate, and fermenting and decomposing the fermenting substrate by adding clean water under the condition of 20 to 35 DEG C to obtain the fermenting liquid. The fermenting liquid has a good effect for killing and inhibiting the southern root nematode, and the fermenting liquid can be used as a typical nonchemical synthesis nematode inhibitor to be applied to a farm field ecological system for a long term and is particularly applicable to the organic agriculture.

Description

Technical field [0001] The invention relates to the field of agricultural organic medicaments, in particular to a fermentation broth with nematode control effect and its application. Background technique [0002] Root knot nematodes cause up to 157 billion economic losses to world agriculture every year. Non-chemically synthesized nematode poisoning agents and nematode inhibitors are becoming more and more popular. In tropical and subtropical areas with abundant rainfall and mild climate, root-knot nematode damage is particularly serious. In China, such areas are also important cassava producing areas and livestock and poultry breeding areas. So far, there have been some reports on retting chicken manure piles with decomposed manure liquid to improve soil fertility, but there are still reports of using cassava molasses alcohol waste liquor and fresh chicken manure as a substrate to ferment a fermentation broth with nematode control effect. blank. [0003] Non-chemically synthes...
