The general plot spacing is 30 to 33 centimeters, and the distance between the points is about 13 centimeters, 1.6 to 18,000 holes per mu, and 2 to 3 seedlings per hole are appropriate. High water and fertilizer plots can be properly sparse, and the density of poorer water and fertilizer plots can be increased as appropriate. Second, scientific watering Thin water transplanting, inch water live trees, shallow water in the tillering period. Saline-alkali land should not be drained to dry fields to prevent returning alkalis to seedlings. In order to control the occurrence of invalid tillers and improve the rate of tillers and spikes, 20-25 days after transplanting (25,280,000 heads per mu per group), the fields were drained and the fields were allowed to dry for 7-10 days. The booting, heading, and flowering stages are the time when water is needed most during rice life. When the water shortage causes the development of young panicles to be blocked and the valleys increase, the shallow water layer should be maintained. During the grain filling period, wet and dry alternate irrigation methods are adopted to make the field always maintain the state of water and gas exchange, use water to adjust the gas, and use gas to grow roots to protect the leaves to prevent premature aging. One week before harvest, cut off water. Third, balanced fertilization 1. Increase Organic Fertilizer Organic Fertilizer contains many organic substances, full nutrients, and long-term fertilizer effects. It can provide balanced nutrient supply to rice and can effectively improve soil structure and continuously fertilize fertility. The application of organic fertilizer in saline land can reduce the salt and alkali hazards. 2. Formula Fertilizer “Thousands of Miles†Formula Fertilizer is a technical expert of the County Agriculture Bureau. According to the soil nutrient status in the rice area of ​​our county, it combines the fertilizer-demanding rules of rice to produce a highly efficient multi-formula fertilizer. The chemical formula is scientific and easy to apply, and the effect of increasing production is obvious. Generally, 40% of the formula Mushi 40 kg of fertilizer and about 50 kg of ammonium bicarbonate (or 15-20 kg of urea) can meet the demand for nutrients throughout the rice growth period. 3, proportion of fertilization Rotation before Mushi organic fertilizer 2? 3 Fang, formula fertilizer 20 kg as the base fertilizer, before transplanting Miao 25 ​​kg of ammonium bicarbonate for surface fertilizer. Top dressing should grasp the principles of heavy weight, medium weight, and light weight. It should promote early-onset and early-middle-stage growth of rice, and it should have large spikes, full grains, and no premature senescence at the later stage. After turning green, rice was topped with 20 kg of ammonium bicarbonate and 20 kg of formula fertilizer. In the middle of July, dry the fields, without watering or fertilizing, and control the roots to make the rice plants lightly yellow. On the basis of falling yellow, at the end of July or the beginning of August, 5 kg of urea was used as panicle fertilizer to promote panicle large grains. During the grain filling stage, potassium dihydrogen phosphate, rare earth and other foliar sprays can increase seed setting rate and 1000-grain weight. Fourth, comprehensive prevention and control of pests and diseases 1. Pests and insect pests mainly include large borers, secondary borers, rice leaf roller, rice borers, and rice planthoppers. The use of fipronil, insecticidal double, BT emulsion, methotrexate, isoprocarb and other biological pesticides or high efficiency and low toxicity pesticides are used interchangeably. The smaller the worm age, the better the control effect. The use of high-toxicity, high-residue pesticides such as ammonium formazan and 1605 is prohibited. 2. Diseases and diseases mainly include stripe blight, rice blast, sheath blight, rice smut, and leaf spot disease. Stripe leaf blight should focus on prevention and control of planthoppers in Putian and Daejeon during the tillering period, cut off the transmission route of viruses, implement fitness cultivation, and enhance the resistance of rice; rice blast should focus on the prevention and treatment of panicle stem blast, breakage period and after the flowering 75% tricyclazole was sprayed twice; density and nitrogenous fertilizer was more severe in the plot, and when the incidence of field acupuncture was up to 10%, spraying with jinggangmycin plus triadimefon was used to control and the amount of liquid was large. Sprayed to the lower part of the plant; rice smut can be controlled with thiophanate-methyl and jinggangmycin one week before the break and at the heading stage; leaf spot disease of flax is common in recent years, and 75% of tricyclazole can be added to Sichuan rice.
