Rice Green Control Measures
The habitat structure and microclimate of the paddy ecosystem are relatively simple and there are only relatively few resources because the fewer species diversity in the paddy ecosystem, the more empty habitat niches, which results in extremely unstable rice paddy ecosystems. Insect pests occur frequently and yield and quality are easily affected.
1. Use resistant varieties. Combining with the occurrence of local weather pests and diseases, select suitable disease-resistant varieties.
2. Salvage sclerotia. According to the characteristics of the sclerotia formed in the later stages of the disease, it will fall into the rice fields and become the pathogen of the next year. When cultivating fields, salvaging sclerotia and burning them are important for the prevention and control of sheath blight.
3. Physical, biological and other prevention and control technologies. Light trapping and physical control techniques; sexual attractant trapping; rice-duck commensal insecticide weed control sheath blight; use a series of high-efficiency biological pesticides to control various pest technology.
4. Paddy field super delivery of drugs to prevent childbirth pest technology. Two or three days prior to transplanting, seedlings were sprayed to control aphids, rice blast, rice thrips, and rice planthoppers to prevent or reduce the occurrence of field diseases and insect pests.
5. Spike heading early mixed drug preservation technology. In the early stage of rice heading, the pesticides for preventing rice blast were mixed with pesticides for the control of sheath blight and rice planthoppers to achieve the purpose of a single application of pesticides to prevent various pests.
6. Paddy fields cultivating hoeing techniques. In the peak season of wintering and pupation of maggots, timely cultivating of winter free field and green fertilization field, and immersing deep-water dipping, can make maggots unable to normal emergence and reduce the occurrence base.
7. Reduce drug use and increase production. With 40% chlorantraniliprole thiamethoxam (Fagoe) wettable powder to prevent warts, rice leaf roller, with 30% difenoconazole clozconazole (Ai Miao) EC to control sheath blight.
The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
