Abstract
The invention discloses a sustain-released bio-control agent, which comprises the following raw materials: biodegradable solid waste, inoculated fungal spore powder, and a binding agent. The invention also discloses a preparation method of the sustain-released bio-control agent. The preparation method comprises the following steps: step one, grinding biodegradable solid waste into fragments with a particle size of 2 to 4 mm, and then evenly mixing the fragments with inoculated fungal spore powder to obtain a material (a); step two, artificially binding the material (a) obtained in the step one by the binding agent to prepare particles; step three, and painting colors on the surface of the particles to obtain the sustain-released bio-control agent. The invention also relates an application of the sustain-released bio-control agent, which can be evenly sprayed into farmland or woodland through human, machinery, display shell, or aviation. The preparation method has the advantage that the biodegradable waste is converted into valuable resources. Moreover, the spore powder can be slowly released, and thus the bio-control effect can last for a long time.
Description
Technical field
The present invention relates to biological control plant disease field, particularly relate to a kind of slow release type biological control agent and its preparation method and application.
Background technology
Crops and plant pest can make plant leaf blade generation variable color, downright bad, deformity, wilt, perforation, the symptom such as caducous, serious constrains crops, economic crops, the high yield of medicinal plant, stable yields and high-quality, Prevention Technique conventional at present mainly contains the anti-therapy of chemical method and measure of biotic control increasingly mature in recent years, but along with people are to pollution-free, the raising day by day of pollution-free green food cry, owing to there is the accumulation of agricultural chemicals in chemical control method, contaminated environment, the defect such as the harmful and health requirements of people can not be met, biological control mainly realizes the control of damage by disease and insect by the allelopathy between biology, progressively replacing traditional chemical control method and becoming a kind of important extermination of disease and insect pest means, but measure of biotic control ubiquity biocontrol microorganisms growth time is short, be subject to the unfavorable factors such as external environment condition variable effect, seriously constrain its control agriculture, the effect of forestry pests & diseases, so be difficult to the continuation realizing the extermination of disease and insect pest.Therefore, while ensureing biological control effect stability, how realize the continuation of the extermination of disease and insect pest, meet the extermination of disease and insect pest in plant growing cycle for most important biological prevention.
Along with human industry's civilization, the raising of agricultural civilization and daily life level, the solid waste kind that industrial or agricultural activity and everyday life produce and quantity unprecedentedly increase, and along with the progress of science and technology and being rooted in the hearts of the people of environmental protection concept, biodegradable material has become the chief component of all kinds of solid waste, although all kinds of biodegradable solid refuse can disintegrate in the environment, but easily can cause visual pollution and landscape pollution owing to discharging arbitrarily and being scattered, therefore, current processing mode is still concentrated and is cleared, sanitary landfills or burning disposal are done in unification.Landfill disposal is mainly based on the fermentation of anaerobe, therefore poisonous and hazardous percolate can be produced, percolate can under the seepage effect of earth's surface direct polluted underground water, also can polluted surface water further if disposal options is improper, and the burning process of solid waste can produce as toxic and harmful contaminated airs such as bioxin, if and biodegradable solid refuse aerobic degradation in natural environment, then product is mostly as CO
2, H
2the Small molecular that O, ethanol etc. are nontoxic, limited to the pollution capacity of environment.
According to the inventors knowledge, there is no document or patent at present and openly report that utilizing biodegradable solid refuse to wrap up fungal spore powder implants farmland, forest land for persistent prevention and elimination of disease and pests.
