Problems solved by technology

[0003] At present, it is urgent to study and solve the organic rice production technology and industrial operation mode. In order to produce organic rice, many farmers ignore rice, resulting in a serious reduction in rice production and failing to achieve due economic benefits; The yield is still secretly using pesticides, which greatly reduces the organic rice; how to prevent insects and diseases of organic rice without using pesticides has become the most important issue in current organic agriculture

Embodiment 1

[0015] First of all, EM bio-bacteria compost is produced. After fully mixing rice straw, livestock and poultry manure, tea oil cake, rapeseed oil cake, brown sugar and EM bio-bacteria stock solution, composting fermentation is carried out according to the traditional composting method and EM bio-bacteria micro-ecological engineering technology , made into EM biological bacteria compost.

[0016] When plowing, use 50kgEM biological bacteria compost per mu, and plow into the soil; after plowing the paddy field, stock 800 loach per mu; soak the seeds with 200 times the dilution of EM biological bacteria stock solution for 2 hours; use 200 times EM Soak the seedlings in the dilution of the biological bacteria stock solution for 2 hours before transplanting; then spray the seedlings with 1000 times the dilution of the EM biological stock solution every half a month; m, gradually raised to 1.3m in the later stage of rice growth, and the installation positions are distributed in a tr...

Embodiment 2

[0018] When plowing, use 75kgEM biological bacteria compost per mu, and plow into the soil; after plowing the paddy field, stock 900 loach per mu; soak the seeds with 200 times EM biological bacteria stock solution dilution for 3 hours; use 200 times EM Soak the seedlings in the biological bacteria stock solution dilution for 3 hours before transplanting; then spray the seedlings with 1000 times the EM biological bacteria stock solution dilution every half a month; m, gradually raised to 1.3m in the later stage of rice growth, and the installation positions are distributed in a triangle with a distance of 150m between each lamp.

Embodiment 3

[0020] When plowing, apply 100kg of EM biological bacteria compost per mu, and plow into the soil; after plowing the paddy field, stock 1,000 loaches per mu; soak the seeds with 200 times the dilution of EM biological bacteria stock solution for 4 hours; use 200 times EM Soak the seedlings in the biological bacteria stock solution dilution for 4 hours before transplanting; after that, spray the seedlings with 1000 times the EM biological bacteria stock solution dilution every half a month; m, gradually raised to 1.3m in the later stage of rice growth, and the installation positions are distributed in a triangle with a distance of 150m between each lamp.

Abstract

The invention provides a method for preventing insects and diseases of organic rice, belonging to the technical field of rice planting. The method comprises soil improvement, loach breeding, seed soaking in bacteria liquid, seedling soaking in bacteria liquid, bacterial liquid spraying and insect killing through lamp trapping. The method has the following beneficial effects: the EM (effective microorganisms) biological bacterium compost can improve the soil microorganism activities, increase the distribution density of the microorganisms and increase the organic content of the soil; the eggs and larvae of pests in the paddy fields can be killed by breeding loaches; the disease resistance of rice seeds and seedlings can be improved and such bacterial diseases as rice blast, sheath blight and bacterial blight can be effectively controlled by soaking the seeds and seedlings in the bacteria liquid and spraying the bacteria liquid; the method of killing insects through lamp trapping is to effectively kill pests by utilizing the phototaxis and wave tendency characteristic of the pests and can help control such migratory pests as botyodes diniasalis walker, tryporyza incertulas, chilo suppressalis and rice planthoppers; and compared with the existing methods for killing insects and preventing diseases with pesticides, the method completely eradicates pesticide residues and harms of the pesticides to soil and food and is an effective method for producing organic rice.

Description

technical field [0001] The invention relates to a method for planting organic rice, in particular to a method for preventing insects of organic rice when pesticides are avoided. Background technique [0002] Organic food is recognized as a quality and safe food in the world today, and has become the first choice for people to eat. Organic rice is not only one of the important edible products, but also an important raw material for the development of related organic foods. Organic rice production is characterized by eco-friendliness and environmental friendliness. In the production and processing process, chemical synthetic substances such as pesticides, chemical fertilizers, production hormones, chemical additives, and preservatives are not used, and genetic engineering technology and its products are not used. The use of organic rice is advocated. Fertilizer and biological integrated control of diseases, insect pests and weeds and other methods. With the intensification o...
