Clean rice cultivation is a new rice cultivation technology that combines every aspect of rice production with environmental pollution control. Rice clean cultivation is divided into three kinds of pollution-free rice cultivation, green rice cultivation and organic rice cultivation. Non-pollution rice cultivation is low-grade clean cultivation; green rice cultivation is mid-range clean cultivation; organic rice cultivation is high-grade clean cultivation. The clean cultivation of rice in our county has been promoted for more than ten years. The selling price of rice has increased by two to three times, and the income of rice farmers has doubled, resulting in good economic and social benefits. 1. Rice fields that are not rice fields can be cleaned and cultivated. Only paddy fields (regions) with the following conditions can be cleaned: 1. The air is clean and free from pollution, and the surrounding vegetation and ecology are good. There are no industrial and mining pollution sources, no hospitals, no railways, and high-grade highways within 1 km. 2. Sufficient water sources, no pollution, convenient irrigation and drainage, and drought and flood protection. 3. The soil is non-polluting and has a deep, fertile, well-pervious layer of tillage, strong water retention and fertilizer retention, organic matter content of 1.3% to 2%, and soil pH value of 5.5 to 7. Second, the selection of suitable varieties should use strong resistance (especially resistance to pests and diseases), suitable for the local environmental conditions of good rice varieties. The excellent varieties available for use in the middle and lower reaches of the Yangtze River include: Changyou No. 11, Zhuliangyou 819, Neiliangyou 6, Fengyou 299, Zhongzao 22, Ningjing No. 1, Huaibei No. 9, Xudao Number 3, Changyou 1, Xinliangyou 6380, Xieyou 9308, II You 7954, Liangyou Peijiu, Fengliangyou 4, etc. Third, nurture high-quality brilliance The selected Putian soil should be fertile without pollution, and drainage and irrigation should be convenient. The ratio of paddy field area to field area should be 1:15 to 20 (7 leaf transplanting seedlings) or 1:20 to 25 (6 leaf transplanting). seedling). Putian should use organic fertilizers such as pigs, cattle, and human feces that have not been contaminated and have been fully decomposed. Fertilizers should not be used at the seedling stage. During the cultivation of dry seedlings, 10 to 15 days before sowing, 2500 to 3,000 kilograms of mature manure, 30 to 40 kilograms of superphosphate, and 12 to 15 kilograms of potassium chloride should be applied per acre 10 to 15 days before sowing, and then turn over 2 or 3 times and be carefully handled.畦 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 压 畦 畦 畦 畦 畦 畦 畦 畦. If seedlings are transplanted at the 6-leaf stage, 130-150 grams of dry rice will be sowed per acre; if the seedlings are transplanted at the 8-leaf stage, 70-80 grams of dry rice will be sowed per acre. Sow carefully and evenly. After sowing, the seeds should be lightly pressed and rubbed, covered with nutritious soil or grass and wood ash, etc. (covering the thickness is not suitable for the valley is appropriate), depending on the amount of water poured on the soil moisture, to prevent the soil moisture is not enough to affect the emergence. To prevent and control seedlings weeds, the best weeding is done manually; when there is no manpower, we must use non-polluting herbicides. We can use 32% bialaphos EC every acre 80 to 10 grams of water to spray 40 to 50 liters evenly, or use 60% butachlor EC 100 ml water to spray 40 to 50 liters evenly. During the period of early rice mulching and filming, when the daily average temperature is higher than 20°C, the membrane should be removed and cooled to reduce the temperature to about 30°C. When the seedling grows for 5 to 8 days after sowing, it is necessary to peel off the film and cultivate the seedling. During the growth of the seedlings, if leaf curling occurs at noon, it should be properly watered after 4 pm. When planthoppers and other pests and diseases are found at the seedling stage, white-freezing seedlings, Bacillus thuringiensis, and other pollution-free pesticides should be promptly applied for prevention and treatment. Do not bring pests and diseases into the field with the seedlings. Fourth, do a good job in field management 1. Whole field and planting. Daejeon should be in good condition 6 to 10 days before insertion (throwing). Before the whole field, it is best to apply basal fertilizer according to the requirements of the soil testing formula. Normally, per acre, non-polluted and cooked pigs, cow manure 1600-2000 kg, calcium magnesium phosphate fertilizer 30-40 kg and potassium chloride 12-15 kg, then plowing Fuping 2 times. The spacing of rows of rice planted in Daejeon is determined based on soil fertility and different varieties. Indica rice spacing is 30 cm, plant spacing is 13 cm, and 16,000 to 18,000 bf (acupoints) per mu are planted to ensure basic seedlings reach 65,000 to 8 Million seedlings. 2. Apply fertilizer. Pollution-free and green rice production can use urea and other chemical nitrogen fertilizers to give birth to effective tillers after returning green, while organic rice production can not be topdressed with chemical nitrogen fertilizers. Only mature human and animal urine can be used. After Daejeon's rice returns to green, it is generally used to spread 12 to 15 kg of urea per mu, or 400 to 500 kg of water to humans and livestock. 3. Shi Zhuang panicle fertilizer. Strong panicle fertilizer is applied in the period from the extraction of the inverted 4 leaf to the inverted 2 leaf of the rice, which can increase the percentage of the panicles and the grain weight, spreading 5-7 kg of urea per acre, and the production of organic rice per acre. ~ 300 kg. 4. Apply granulation fertilizer. The full-grain fertilizer can extend the functional period of the leaves, increase photosynthetic products and grain weight, improve rice quality and promote ripening. This fertilizer was applied during heading and flowering of rice. Sorghum fertilizer should be flexibly based on the conditions of the seedlings and the weather. Paddy fields with good growth in the late stage should not be applied with full-grain fertilizer; grain fields with weaker late growth, faded leaf color, or insufficient top-dressing should be fully applied. Most of the satiety fertilizers were fertilized with roots, spraying 0.15 kg of potassium dihydrogen phosphate, 0.5 kg of urea, and 50 liters of water per acre of leaves, applied in the morning and evening. 5. Use water rationally. Paddy fields should be kept in shallow water after planting, so as to facilitate seedling rooting and promoting livelihood. Shallow water irrigation during the delivery period is conducive to promoting childbirth. After the effective delivery is achieved, the water should be used to control ineffective delivery and the field should be kept dry and wet (mainly based on wetness). In the field from heading to maturity, shallow water layers should be maintained for plant growth, transportation, and accumulation of photosynthetic products. Rice is generally not watered when it enters the yellow ripening stage, and it should be allowed to naturally dry out. 6. Non-pollution prevention and control of pests and weeds. The application of organic rice paddy field weeds is artificially or through fish paddies and ducks. Non-pollution rice and green rice paddy fields, can be used after the seedlings return to green with 60% butachlor EC per acre 100 ~ 120 ml mixed with 10 ~ 15 kg fine soil applicator, you can block the weeds. For organic rice paddy fields, for example, the lepidopteran pests such as C. suppressalis, rice borers, and rice leaf roller, etc., should be sprayed at a rate of 1 million to 2 billion in each year for each pest. 150 times the liquid; the occurrence of rice planthoppers and rice leafhoppers, etc., should be sprayed in the young age of the spores per acre with spores 500 to 8 billion / g of white stoma vaccine powder 0.3 to 0.5 kg, spraying 40 to 50 liters of water or Mix 15 kilograms of dried loess; apply sheath blight, rice blast, etc. Each mus should be sprayed separately as soon as possible 5% Jinggangmycin soluble powder 120 ~ 150 grams (40 to 50 liters of water, every 5 to 6 days and then spray 1 Secondly) and 2% quercetin emulsifiable concentrate 700 to 1000 times (spray every 5 to 6 days before spraying once); occurrence of rice virus disease, spraying plant virus vaccine per acre 500 to 600 times liquid (every 5 to 6 days Spray once more). The occurrence of pests and diseases in pollution-free rice and green rice paddy fields should be prevented and treated as early as possible in order to improve the control effect. In case of rice blast disease, use 30% rice bran oil per acre to spray 40 to 50 liters of water per mu; if there is a sheath blight, spray 20% per acre with 50 grams of water to spray 40 to 50 liters; Alum, spraying 10 to 50 grams of 10% imidacloprid per acre 40 to 50 liters of water spray; occurrence of rice borers and rice planthoppers, per acre with 5% fipronil EC 40 to 50 ml of water spray 40 to 50 liters. The basic principles for the clean cultivation of rice and pests and diseases are as follows: 1 Use of pollution-free biological or plant pesticides; 2 Insect pests should be detected as early as possible, and early control should be adopted. It is best to use drugs during hatching or larvae of 1-2 instars; Control as far as possible without drug prevention and treatment; 4 can not pick the treatment of the whole field medication; 5 can use a drug to prevent the use of two drugs; 6 try to use a kind of pesticide that can control several pests at the same time. V. Precautions Cleanly cultivated rice should be collected, hit, sunned, stored and processed separately. It is forbidden to follow secondary pollution in the production process; the production tools used must be pollution-free and non-polluting.
