Spring seeding and seedling training is about to begin. Good seed processing and weed control for early rice are important technical measures to seize the early rice harvest. First, the early rice seed processing Early rice seeds should be sown before sowing, seed selection, remove disease, pods, and then treated with pesticide soaking to prevent early rice species transmission diseases, the specific method is: control of rice bakanae disease use 25% mimo Amine EC 2 ml water 2-3 kg, dubbed 1000-1500 times the liquid can be directly dry rice immersed 3 to 4 kg, conventional rice leaching 48 hours, after soaking can direct germination sowing. If soaked with 80% "402" 1500 times liquid, it should be cleaned before germination. Second, live field, machine inserted, transplanting field chemical weeding 1, field weeding: seed germination sow the seeds, can be used within 1 to 3 days after sowing mu 40% benzacetam WP 45-60g Water 30 kg spray, after the spray ditch to have shallow water to keep the wet plate. In the second to third leaf stage of the seedlings, weeds are drained when the two leaves are in one heart and one heart, and more fields in the grass can be used in the mu 2.5% Penoxsulam SPM 40ml+10% Imidacloprid 30g+10 % of benzethonone 30 g or mu with 50% quinclorac 50 g +10% imidacloprid 30 g +10% benzethononide 30 g, 30 kilograms of fine spray, can control valerian and other broad-leaved weeds, At the same time, it can also treat locusts; thousands of gold fields can be used 10% cyhalofoplavide 40-60 ml water 30 kg fine spray; 24 hours after the drug rehydration to the heart of the seedlings below the leaves, water retention 5-7 days. 2. Machine inserting early rice fields, throwing fields: After 6-7 days of transplanting, the seedlings have survived and turned green, which can be combined with the application of topdressing urea, mixed and spread, and 50% butyl benzyl herbicide 80-100g can be used. The field should retain water for 5-7 days, but Tian Shui can't pass over the heart. 3. Transplanting Early Rice Fields: After 6-7 days of transplanting, 30-40 grams of 30% ethylbenzyl herbicides can be used. Field water management refers to throwing fields.
