Special nematode-resistant growth-promoting biological fertilizer for wheat

Abstract

The invention relates to a special nematode-resistant growth-promoting biological-fertilizer for wheat. The biological-fertilizer can effectively solve the problems of prevention and treatment of wheat cyst nematode disease, and can promote wheat growth, yield increase and synergy and environmental protection. The bio-fertilizer is prepared by uniformly mixing the following components in percentage by weight: 35-45% of compound microbial agent, 10-15% of urea, 30-35% of monoammonium phosphate, 5-10% of potassium chloride and 5-10% of potassium humate. The fermentation medium and culture conditions are simple; convenient operation, low production cost, and easy industrial production are realized; the special anti-nematode growth-promoting biological fertilizer for wheat is developed aimingat the fertilizer requirement of nitrogen, phosphorus and potassium of wheat and the morbidity of cyst nematode of wheat. The wheat cyst nematode control effect is good, the incidence rate and the morbidity index of the wheat cyst nematode can be obviously reduced, the cereal cyst nematode disease is effectively controlled, wheat growth can be promoted, the thousand seed weight is increased, thenthe yield increasing effect is achieved, energy is saved, environmental friendliness is achieved, and economic and social benefits are huge.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a special biological fertilizer for nematode resistance and growth promotion for wheat. Background technique [0002] Wheat cyst nematode, also known as wheat cereal cyst nematode (CCN), is an important soil-borne disease that harms wheat and other cereal crops. It has a wide range of incidence in my country and is difficult to control. Therefore, the prevention and treatment of this disease should adopt the policy of "prevention first, comprehensive prevention and control". In plots where wheat cyst nematode occurs seriously, soil fumigants such as chloropicrin, D-D mixture and dazomet or nematicides with contact or systemic effects are usually used, such as aldicarb, which can Effectively control wheat cyst nematodes. Although the control effect of chemical drugs is relatively good, it causes great harm to human and animal health, high cost, and pollutes the environment. ...

AI Technical Summary

Problems solved by technology

But according to the newness of domestic literature search, it can be seen that most of them are chemical preparations and microbial bacterial agents, and there is no public report of the special anti-nematode growth-promoting bio-fertilizer for wheat provided by the present invention
