Problems solved by technology

At present, most of the biological herbicides use fungi, but there are few successful cases of weed control using the antibiotics produced by actinomycetes, especially the biological herbicides that use fungi, actinomycetes and natural plant extracts. Few reports on research and application

preparation example Construction

[0069] The preparation method of embodiment is the following steps:

[0070] A, the preparation of medicinal plant extract:

[0071] a. According to the calculation of weighing 20-40 kg of medicinal plant raw materials chamaejasma, cumin, cnidium and lovage, add 200 liters of water, boil on low heat, extract at 100°C for 24 hours, filter, and continue to add 200 liters of water to the residue , reflux extraction at 100°C for 24 hours, filter, combine the two extracts, concentrate under reduced pressure to 20-40 liters, sterilize at 121°C for 20 minutes, and set aside;

[0072] b. According to the calculation of weighing 5 kg of medicinal plant raw material garlic, cut it into mashed garlic with mechanical equipment, add 50 liters of distilled water, enzymolyze it in a water bath at 50°C for 4 hours, filter, collect the filtrate, concentrate the filtrate under reduced pressure to 5 liters, and place Store at 4°C for later use;

[0073] B, preparation of compound bacterial age...

Abstract

The invention relates to a liquid state composite biological multivariable control paddy herbicide. The herbicide is characterized by being prepared from medicinal plants and multiple species inoculant. The medicinal plants comprise, by weight, 5-25 parts of radix euphorbiae lantu, 5-25 parts of cumin, 5-25 parts of garlic, 5-25 parts of radix angelicae pubescentis and 5-25 parts of common cnidium fruits. The multiple species inoculant comprises, by weight, 5-20 parts of bacterial liquid of streptomyces lavendulae, 5-20 parts of bacterial liquid of streptomyces fradiae, 5-20 parts of bacterial liquid of streptomyces viridocbromogenes, 5-20 parts of bacterial liquid of streptomyces griseolus, 5-20 parts of bacterial liquid of alternaria, 5-20 parts of bacterial liquid of botryis cinerea and 5-20 parts of bacterial liquid of curvuloria lunata. The biological multivariable control paddy herbicide is efficient, low in toxicity, environmentally friendly and not likely to produce resistance and particularly has the remarkable restraining effect on barnyard grass, nutgrass flatsedge, semen euphorbiae and duckweed.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to a liquid composite biological multi-controlling herbicide for paddy fields and a preparation method thereof. Background technique [0002] Paddy field weeds are plants that directly or indirectly interfere with rice production in the specific growth environment of rice. The harm it causes to rice production is mainly manifested in competing with rice for glory and nutrition, resulting in reduced production, weed seeds mixed with rice, which can reduce rice quality, spread diseases and insect pests, hinder agricultural operations, increase production costs and labor costs. The control methods include cultivation control, tillage control, biological control and chemical control. Chemical herbicides used in chemical control have been used effectively for the control of weeds in paddy fields for more than a century. However, due to the extensive application of chemica...
