Tilletia controversa teliospore composting harmless treatment method

Abstract

The invention discloses a Tilletia controversa teliospore composting harmless treatment method. The method is as follows: composting the raw material to be treated for more than six days, wherein the water content of the raw material is 60-70wt%, the C / N is 30-40 and the internal temperature of a pile body is 50-60 DEG C. The technical scheme provided by the invention utilizes the high temperature generated in the composting process to kill pathogenic bacteria, weed seeds, worm eggs and the like. In addition, the soil microorganisms in the pile body can be used for degrading the important components of plants, such as cellulose and lignin and the converted product can be used as the fertilizer, thus the environment can be protected, the soil fertility can be increased, the soil water retention capacity can be increased, the volume and smell of an organic material and the pathogenic bacteria can be reduced and the recycling of resources can be realized.

Description

technical field [0001] The invention relates to a harmless treatment method for pathogenic microorganisms, in particular to a compost microbial fermentation treatment technology for Tilletia controversa Kühn (TCK). Background technique [0002] Tilletia tritici (TCK) is a very harmful phytoquarantine pathogen, which can lead to a 20%-75% yield reduction of wheat, and even lead to extinction of wheat yield in the epidemic year. The viability of the TCK galls scattered in the field can last as long as 10 years, and the TCK teliospores passing through the animal digestive tract also have a germination rate as high as 64% ("Wheat Dwarf Bite Smut" China Agricultural Press, 2002: 36). If the straw, wheat bran and other products infected by TCK are not treated with TCK inactivation, once an infection source is formed, or with the continuous rotation of crops, TCK will accumulate and increase year by year in the field, forming a relatively high level of pathogenic bacteria per unit...

AI Technical Summary

Problems solved by technology

However, irradiation treatment is not widely used due to the influence of electron beam penetration ability and device flexibility; chemical treatment will cause certain damage to the environment, and its practical application will be affected; the quality of wheat will decline after heat treatment.

It is difficult to deal with wheat products carrying a large amount of TCK by using the above three methods
