Early rice has methods
Wet and dry alternately promoting early-onset current, early rice should be scientific management of water, water temperature adjustment to help early hair. Fill the water with green seedlings. The water layer is suitable for 15-17mm. Based on this, it is possible to deepen the water due to the sky water, ie rainy or cloudy days. The sunny days will be lighter and the water temperature and mud temperature will be higher than the air temperature. °C ~ 3 °C. During the tillering period, the water in the management of the plant adheres to alternating wet and dry conditions and is mainly wet, and the depth of irrigation varies from field to field. Soil fields and well-maintained fields are generally about 17 mm, and the water retention is poor or the sand loam is slightly deeper, generally 20 to 30 mm, so that the early rice can be delivered quickly.
Early recovery of foot fat early recovery is early recovery, grab sunny days, 7-10 days after transplanting, rapid application of a fertilizer; Second, the amount of fertilization should be sufficient, topdressing urea per acre of 5 to 7.5 kg; three is the shortage of fertilizer field block To reapply, urea is not less than 7.5 kg per mu; Fourth, according to the current weather changes in cold and warm and cold soaking of mud and frozen seedlings, apply 2.5 to 3 kg of potassium per acre plus 1 kg of zinc fertilizer, after transplanting Twenty days to cure stiff seedlings, one week after top dressing, apply fertilizer to the three types of seedlings.
Timely chemical weeding The main weeds in the early rice field are grasses, grasses, grasses, sedges, and sedges of the Cyperaceae, dwarf arrowheads and bamboo grasses of the broadleaf weeds. The herbicides that can be mixed with soil or fertilizer are: 25% refined grass star, 25-35 grams per acre, 5-9 days after transplanting; 20% glutinous rice, 30-45 grams per acre. 5 to 12 days after planting. The herbicide is optionally one, 20-25 kilograms per acre of fine soil or chemical fertilizer, spread evenly after morning rice leaves dew or after 4 pm.
Prevention and treatment of pests, early-onset and dry-early breeding, easy to attract larvae to lay eggs, egg incubation is generally in mid-late May, should be a double insecticide, killing crickets, etc. for a chemical control, early rice sheath blight occurs almost every year, Be diligently checked and use medication promptly.
