Rice spring plant protection technology
After the spring, the city began to enter the spring sowing period. The "agricultural stations" (service groups) of townships and streets should do a good job of prevention and control of rice pests and diseases as soon as possible, grasp the crucial period during the spring sowing period, and cultivate healthy and disease-free seedlings to lay a good foundation for the stable development of grain in our city. First, choose disease resistant varieties to avoid single species Sensitive varieties or old varieties that have been planted for many years with continuous decline or even loss of resistance are planted in a single large area. If the susceptible period encounters high humidity conditions, it often leads to outbreaks of diseases such as rice blast. The "agricultural stations" (service groups) of townships and townships shall strengthen publicity and training on the hazards of rice blast, conduct a test on the rate of seed-borne bacteria in heading varieties, and guide farmers in selecting seeds. Second, do a good job in field health, reduce the source of pests and diseases Before and after the spring season, the “agricultural stations†(service groups) of townships and townships should guide farmers to clear the fields, the ditch, the canals, and the mountains, rivers, ponds, weeds, seedlings, and regeneration seedlings near the rice fields. Reducing the base number of overwintering insects of rice gall midge, rice planthopper and leafhopper; early spring plowing irrigation field to reduce the base number of winter aphid; removing the nucleus of sheath blight, removing and burning the diseased straw stacked at the end of Tiantou and Tianqu, and preventing Insect source. Third, do a good job of seed treatment, control pests and diseases Rice seeds carry many kinds of germs, and agricultural stations (service groups) in townships and streets can use soaking and disinfection measures according to local conditions. Common methods are the following: 1. Soaking seeds with 100 grams of emulsifiable concentrate: Soak the grains in 25% to make 2500 to 3000 times dilution of the emulsifiable concentrate for 36 to 48 hours. After soaking, the seeds can be sowed directly. To eradicate germs and reduce the incidence of bastard disease and other diseases. 2, Kwong Ku Ling Soaking: Use 3% Kwong Ling Shui agent 1500 times liquid soaking for 12 hours, picked up and washed germination. 3, strong chlorine soaking seed: the grain pre-soaked with water soaked (early rice conventional pre-soak 24 hours, hybrid rice pre-soaked 12 hours), picked up after drying water, then immersed in 85% strong chlorine 300 to 500 times dilution In the liquid, it is sterilized for 24 hours, and then rinsed with water to germinate and sow germs to eliminate germs and reduce the incidence of bacterial streak, rice blast, bakanae, rice smut, flaming spot, smut, etc. occur. 4, carbendazim soaking: 50% carbendazim 500 times soaking 48-60 hours liquid, wash liquid after germination, can cure bakanae, rice smut, smut and other diseases. Fourth, do a good seedbed disinfection, pay attention to pest control Before the sowing, the flattened lotus root water shall be moistened, and then sprayed on the lotus root surface with 70% diketsu WP or 75% chlorothalonil wettable powder or 3% Guanghe Lingshui agent. It can reduce the occurrence of cotton rot, blight, Phytophthora capsici, and seedling mites. Strengthen the management of fertilizer and water in Putian to prevent rotten species. After the occurrence of cotton rot, blight or seedlings, timely change of water and use of chemical control. Fifth, pay attention to the control of pests Hamada Spring mice have less food, and combining them with rodents to eradicate mice during spring sowing can achieve a multiplier effect. Rat poisons should be highly efficient, safe and free of secondary poisoning rodenticides. Can choose 0.1% enemy mouse sodium bait or 0.0375% killing rodent poison bait or 0.005% bromadiolone bait every 5 meters along the field to vote a pile of 5 grams per pile, focusing on the protection of spring sowing paddy fields.
