Rice cnaphalocrocis medinalis and ecological preventing and controlling method of stem borers

Abstract

The invention relates to rice cnaphalocrocis medinalis and an ecological preventing and controlling method of stem borers. Ducks and chickens are stocked in a rice field to prevent and control insectpests, from the seedling stage of rice, the ducks and the chickens are stocked in the rice field every day, the stocking time is 6:30-18:30 every day, stocking is conducted till the ducks and the chickens can be sold, and the specific preventing and controlling method is implemented according to different stages of the rice. Preying habits of poultry are utilized to prevent and control the rice stem borers and cnephalocrocis medinalis so that the rice stem borers and the rice cnaphalocrocis medinalis can be effectively controlled, pesticide pollution is reduced, and the occurrence of large-area diseases and insects of the rice is effectively controlled and prevented; meanwhile, the utilization value of land is increased, the labor investment is reduced, the labor cost is lowered, production efficiency is improved, the quality and safety of the rice, the ducks and the chickens are high, no pesticide is left, the ecological environment pollution is effectively lowered, the rice yield permu can reach 10% or above, the yield is increased by 65-88 kg every mu, and the efficiency of effectively inhibiting diseases reaches 98.6% or above.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to an ecological control method for rice leaf rollers and stem borers. Background technique [0002] Borers and rice leaf rollers are important pests of rice in my country. Among them, the most common occurrence and damage of rice stem borers are the rice stem borer, the three stem borers and the rice borer. The occurrence of stem borers and rice leaf rollers generally leads to rice yield reduction10 % to 50%, the outbreak of pests may lead to the failure of rice harvest. For this reason, pesticide control is generally used in production, but pesticide control will pollute the environment and affect the quality of rice, and it is easy to make pests resistant to pesticides; while traditional ecological control is to target a certain type or a certain level of pests, such as Ecological breeding techniques such as rice ducks and rice fish can only control pests 0.0-0.5...

AI Technical Summary

Problems solved by technology

[0005] In order to prevent and control the harm of rice pests, farmers use and abuse pesticides in large quantities. Some of them mainly exert stomach poisoning effect on pests and have a long lasting effect, but due to the slow killing speed, the damage cannot be quickly controlled; some neurotoxic quick-acting insecticides It has penetrating insecticidal effect, and is the main agent for preventing and controlling the damage of rice stem borer and rice stem borer, but its duration is short and the control effect is poor.
