Problems solved by technology

At present, due to the popularization of large-scale harvesters in the Huanghuai-Hai Plain, winter wheat straw has basically been directly covered and returned to the field, while corn straw is mainly returned to the field by crushing and plowing. In addition, the decomposition rate of corn stalks is slow after plowing and returning to the field, which has adverse effects on the soil structure of the plow layer and the sowing and growth of wheat.
Some progress has been made in the use of efficient cellulolytic bacteria to accelerate the decomposition of straw, but the application effect in farmland soil also faces the problem of a sharp decline due to many environmental factors

Embodiment Construction

[0076] The production process of the biological preparation of the present invention is further illustrated by the following examples (see accompanying drawing).

[0077] Dry the corn stalks, crush them into powder by machine, add wheat bran and corn flour in a fixed ratio (weight ratio) (straw flour:wheat bran:corn flour=4:3:2), and then add nutrient solution (glucose 10g , MgSO 4 1g, CaCl 2 1g, (NH 4 ) 2 SO 4 15g, distilled water 1000mL) fully stir evenly, make water content reach 200% (volume: weight). After bagging, it is sterilized by high pressure and wet heat (121°C for 60 minutes) to make sterile solid compost.

[0078] Activate the original strain of B1514, streak culture on LB medium plate, and culture at 28°C for 18h. After the cultivation, add 5ml of sterile water to each petri dish, spread it evenly to make a bacterial suspension, put it into liquid LB medium according to the inoculum amount of 2%, carry out shaking table cultivation, and cultivate at 200...

Abstract

The invention discloses a soil-borne disease biocontrol microbial agent suitable for wheat and corn straw returning and a preparation method thereof. Currently, the tendency of generation of soil-borne diseases in straw returning plots is increased, and the farming quality after straw returning is severely influenced. The biocontrol microbial agent fully solves the problems, has the characteristics of strongly decomposing straws and preventing and treating the soil-borne diseases, can quickly decompose straws within short time after being applied on the straw returning plots, can fully utilize nutrition generated by straw decomposition to quickly breed and form preponderant floras in soil, and fully utilize the advantages of the floras to inhibit soil-borne disease producing germs. Moreover, the soil-borne disease biocontrol microbial agent achieves the aims of not only accelerating straw decomposition, improving the soil characteristics and promoting permanent planting and proliferation of biocontrol bacteria in the soil but also being capable of preventing and controlling the soil-borne diseases to the maximum degree, and is suitable for preventing and treating the soil-borne diseases such as wheat root rot, wheat take-all, wheat sheath blight, corn sheath blight and corn basal stem rot.

Description

Technical field [0001] The invention relates to a microbial preparation, in particular to a biocontrol bacterial agent suitable for returning wheat and corn stalks to fields, capable of effectively controlling crop soil-borne diseases, and accelerating the decomposition of stalks, and a preparation method thereof. Background technique [0002] (1) Soil-borne diseases and farming quality problems urgently need to be solved after returning straw [0003] Double cropping of wheat and corn is the main form of grain production in northern China, and straw returning, which is widely used in production, plays an important role in soil improvement. However, in recent years, it has been found that soil-borne diseases of wheat in straw returning fields tend to increase. For example, in 2006, the occurrence areas of wheat sheath blight in Hebei, Shandong, and Henan provinces reached 62, 67, and 1.813 million ha, respectively. 2 ; The occurrence area of ​​wheat take-all in Hebei, Henan...
