Compound successive crop-resistance micro-ecological formulation special for cotton and special bacterial strain and use thereof

Abstract

The invention discloses a composite anti-continuous cropping microbial ecological agent specially used in cotton and the application thereof. The anti-continuous cropping microbial ecological agent of the invention takes bacillus subtilis KTB001 CGMCC No.2564 and trichoderma viride KTF001 CGMCC No.2562 as active ingredients, wherein, the content of the gemma of a fungus of the bacillus subtilis KTB001 CGMCC No.2564 is 50 hundred million cfu / g preparation; the content of chlamydospore of trichoderma viride KTF001 CGMCC No.2562 is 5 hundred million cfu / g preparation. The composite anti-continuous cropping microbial ecological agent of the invention can prevent and control cotton seedling diseases and verticillium wilt. Furthermore, the agent has the effectiveness of increasing cotton output, increasing cotton quality and enhancing cotton stress resistance, and the like, is beneficial to improving soil and reducing environmental pollution, and provides safeguard for producing cotton withexcellent quality.

Description

Special compound anti-recropping microecological preparation for cotton and its special strain and application Technical field The invention relates to a special composite anti-recropping microecological preparation for cotton and its special strain and application. Background technique Cotton is the main raw material for people's clothing and textile industry and an important product for exporting foreign exchange. It is of great significance to the international people's livelihood. However, in recent years, due to the adjustment of agricultural planting structure, the phenomenon of continuous cropping has become very common, making cotton cropping diseases common, such as cotton blight, verticillium wilt, and seedling diseases such as blight and damping-off, especially cotton fusarium wilt and yellow wilt. Wilt is serious. Cotton fusarium wilt and verticillium wilt (referred to as "two wilts") are one of the plant quarantine diseases. It is one of the cotton diseases with...

Problems solved by technology

Since the promotion of hybrid cotton or insect-resistant hybrid cotton, agricultural extension units have relaxed their ideological vigilance, ignored the quarantine system for cotton "two wilts", and frequently transferred seeds (especially in disease-endemic areas), resulting in the rapid development of diseased seeds. Spread, especially in the old cotton fields of long-term continuous cropping, the "two wilts" have become the main obstacle to the high and stable cotton yield, seriously affecting the sustainable development of cotton production
