preparation example Construction

[0020] Provided simultaneously is a preparation method of a composite bacterial agent for plants, which is prepared by a method comprising the following steps:

[0021] For microcapsules, Bacillus polymyxa and Trichoderma are respectively subjected to first-level seed expansion culture and second-level tank culture, and then starch and diatomaceous earth are added to the fermentation tanks of the two, and the temperature is 20-30 ° C. Stir and gelatinize and mix evenly, and then the two gelatinized liquids are made into microcapsules less than 200 μm by low-temperature vacuum jet granulation technology to obtain Bacillus polymyxa microcapsules and Trichoderma microcapsules ;

[0022] The preparation of the composite microbial agent, the prepared Bacillus polymyxa microcapsules and Trichoderma microcapsules are added to a solution composed of corn steep liquor powder, glucose, ammonium sulfate and potassium humate at a temperature of 8-15°C , stir and mix evenly, and at the sa...

Abstract

The invention discloses a composite microbial agent for plants and a preparation method thereof, which relate to the technical field of plant composite microbial agent. According to the invention, a bacillus polymyxa microcapsule granule and trichoderma microcapsule granule compound agent is used for root-irrigation prevention and treatment of watermelon seedlings with wilt in the field; after compounding treatment of bacillus and trichoderma, compared with a contrast without any medicament, the morbidity of watermelon fusarium wilt is obviously reduced, the compound medicament of the two canobviously promote the growth and development of watermelons and cultivate robust plants, the microcapsule granules have the effects of long shelf life, stable drug effect, slow release of effective components for decomposition and volatilization, reduction of dosage, drifting prevention, reduction of environmental pollution, convenience in use, improvement of medicament selectivity and the like, and are one of the most promising dosage forms.

Description

technical field [0001] The present invention relates to the technical field of plant compound bacterial agents, in particular to a plant compound bacterial agent and a preparation method thereof. Background technique [0002] Fusarium wilt of watermelon is called dead seedling disease, wheat cutting disease, and wilting disease. It is a soil-borne disease caused by the infection of watermelon-specific Fusarium oxysporum f.sp.niveum, and its pathogen can survive in the soil. The time is 8 to 10 years. The whole growth period of watermelon will be harmed by Fusarium wilt, which can cause the output of watermelon to drop by 30%, and in some plots, the output will be reduced by more than 50%, or even go out of production. Seriously affect the high-quality and efficient production of watermelon. And, along with the expansion of watermelon planting area, the continuous cropping of watermelon has also continuously increased the occurrence of watermelon wilt. At present, there is...
