High-yielding cultivation techniques for high quality rice

High-yielding cultivation techniques for high quality rice

First, select high-quality, high-yield and good-quality seeds, and rationally plan planting. According to local production conditions and economic conditions, select high-quality, high-product varieties that have been approved and suitable for growing period, and have strong disease resistance, and carry out reasonable planning, concentrate on planting into pieces, and facilitate unified production. Production management, single income, single storage. Currently, the new high-quality rice varieties suitable for planting in the city include: II You No. 7, II You 162, Feiyou Duo Line 1, K You 047, D You 527, D Shanyou 527, D You 68, Soft Rice 11, Xiang You 61, and E excellent series, excellent series. Second, the appropriate sowing, uniform sowing and dilute sowing, cultivation of high quality rice seedlings scheduling arrangements to focus on the temperature of the heading - flowering - fruiting period. Research shows that the suitable temperature of high-quality rice at this stage is 18-28 °C, and there is a good temperature difference between day and night, so when determining the sowing date, the southern districts and counties should be timely timely sowing, the northern region must be appropriately delayed sowing, grouting - During the grain-filled period, the high temperature weather in summer and drought is missed, and the reduction in production and quality caused by high-temperature ripening are avoided. Diluting seeding and seeding and nurturing Zhuang Zhuang are one of the key measures for the cultivation of high quality and high yield. It is best to use dry seedlings and castors for high quality rice production. The sowing of dry seedlings is to broadcast 180-200 g of seedlings for seedlings per square meter of seedlings, 80-90 g of medium-sized seedlings, and 40-50 g of seedlings for seedlings; Breeding seedlings, 150 g seedlings, 100 g seedlings. High-quality conventional rice seedbed sowing 45-50 grams per square meter. In addition, the use of strong blister agents simplifies the traditional breeding programs for dry seedlings and dumplings, one-time bed soil disinfection, acid, chemical control, fertilization, to achieve the purpose of cultivating strong and powerful. Third, appropriate dilute sowing, reasonable planting density under the premise of fertility guarantee, appropriate thinning, increase ventilation and light conditions, increase the nutrient area per plant, in order to improve polished rice rate, the proportion of polished rice, reduce chalkiness rate. Dry and broad-narrow rows are planted in dry land, and the east-west direction is good. High-quality hybrid rice plants will plant 500-1000 litters less than common hybrid rice, throwing loquats according to the size of seedlings, and throwing 1.5-1.8 million litters per mu; high-quality conventional rice will be 10 per mu. 140,000 seedlings are suitable. For plants with compact plant types suitable for dense planting, planting densities can be appropriately increased. Fourth, multi-application of organic fertilizer, nitrogen fertilizer application of phosphorus and potash fertilizer is the basic principle is to apply more organic fertilizer, nitrogen fertilizer to increase phosphorus and potassium. The moderately fertile plots of Mushi 8-8 kilograms of pure nitrogen are applied with phosphorus and potash fertilizers. Basal fertilizer is mainly organic fertilizer, 20-30 lbs per mu, or manure 40-60 lbs, and superphosphate 25 kg; urea 8-10 kg per mu, potassium chloride 6-8 kg, spikelet differentiation and Seedlings at the ear stage were fertilized, and urea was used for extra-root fertilizer during the grain filling period. V. Scientific irrigation and drainage, late-stage heavy-duty management requires shallow water to promote pupa during the post-harvest period, and high-quality hybrid rice during late parturition and planting should be properly suntanned, and should not be re-sunshine. Reducing invalid tillering and enhancing the lodging resistance of rice plants; shallow panicle irrigation at the time of young panicle differentiation, heading, and filling; not too early when water is cut off; drought irrigation during drought season to prevent dehydration from affecting the appearance quality and cooking quality of rice; During the maturation stage, wet and dry seeds are needed; during the yellow ripening period, the field is drained to promote ripening; when harvesting, the field is dried, so as to prevent the rice from soaking in the water and affecting the rice quality. Sixth, comprehensive prevention and control of pests and diseases should adhere to the main agricultural control, use of high-efficiency and low toxicity pesticides for chemical defense. Specific measures: One is to use antibiotics for disease resistance; the other is to improve the methods of medication and implement small-volume sprays. Seven, timely harvest, to prevent the exposure of high-quality rice requires ripening (yellow ripening, rice moisture content of 18% -21%) timely harvest, avoid the rainy days of harvest, after receipt of timely threshing, should not be put in order to avoid fever caused by yellow rice, moldy rice After threshing, promptly dry it, and avoid high-temperature exposure, use a bamboo mat or three-segment soil for drying. Intermittent drying or drying in several days, and air-dry until the water content of rice is about 13%, which is convenient for safe storage. China Agricultural Network Editorial Office
