Planting high-quality early rice should be based on market demand, according to local conditions to adopt certified or certified high-quality rice varieties. Conventional high quality rice seeds require annual replacement. According to the requirements of industrial development, one species, one species, is planted.
First, soaking seedlings
1, germination. Sun seed selection, soaking disinfection, germination using conventional methods.
2, breeding methods. Wet moist seedlings, dry seedlings, floppy seedlings, and two-stage seedlings were used. The requirements for the cultivation of the strong and prosperous are stout and white roots, and they are green and fast after transplanting. In the middle of April, we planted rice and planted seedlings in the early morning and cultivated three-leaf to four-leaf seedlings. In the middle of April, we transplanted the rice and planted four-leaf to five-leaf rice seedlings. After the first transplant on May 1, we inserted the fields. Breed large seedlings with more than 4.5 leaves transplanted; Late spring harvested crops, cultivated seedlings, transplanted and transplanted.
3, sowing time. When the temperature is stable at 11°C, the mulching is used to cover heat, moisture, and moisture. The sowing date is from late March to early April. When the temperature is stable at 8°C, drought and flooding is sown 10 to 15 days earlier than the wet seedlings, and mulching is used to cover the soil. , North Hunan, Xiangzhong March 15 to 20 seeding, Shonan March 10 to 15 seeding. The sowing date of floppy disk drought and sowing is 8 days earlier than that of moist weed, and so on in March in Xiangbei and Xiangzhong in March 20th to 25th, and sowing in Xiangnan in March 15th to 20th.
Second, transplanting
1, transplanting time. The average daily temperature is stable when planted at 15°C. The winter free field can be planted before April 20, and the green field can be planted before April 25; the early rape field can be transplanted from the end of April to the beginning of May.
2, planting density. Wet seedlings are planted with 150,000 seedlings and 200,000 seedlings, preferably 13.3 centimeters (16.7 centimeters plus 33 centimeters) centimeters of width and width for transplanting, ie, wide row spacing and narrow row spacing, and 60 thousand seedlings of hybrid rice seedlings. ~ 100,000 seedlings; dry seedlings should be planted and moistened with rare earthworms. Each 667 square meters of seedlings should be planted with 100,000 seedlings to 120,000 seedlings, including 50,000 seedlings of basic hybrid rice seedlings and 80,000 seedlings; 20,000 pods were planted, 400 trays were thrown 55 trays to 60 trays, 353 tray trays were cast 60 trays to 65 trays, and the compartments were 1.5 meters to 2 meters wide, leaving 30 centimeters wide aisles between the compartments and 10 to 12 centimeters deep. Castings are carried out in several stages, 70% of the total number of seedlings thrown in the first round, and the remaining 30% thrown in the second round, and then replenishing and thinning.
Third, control weeds in accordance with different ways of breeding and transplanting, use different herbicides, according to the correct use of the method used. Wet sputum selected Sao De, Da Da Zhuang, and Putian Qing; in the field, quinclorac was used for the field, and benzidine, stalks, aphids, and quinclorac were used in the field, and the fields were selected for autumn, crops, and crops. Good, Tiancaojing, butachlor and so on. Daejeon applied pesticides 5 days to 7 days after transplanting and maintained the water layer for 7 days. Fourth, fertilizer and water management
1, fertilization management. Apply 35% of rice special compound fertilizer from 40kg to 45kg per 667m2. When transplanting fields before transplanting, they can be applied in one-time full-layer, and can also be combined with urea, ammonium sulfate, superphosphate, ammonium phosphate, potassium chloride and other simple fertilizers. The dosages of pure nitrogen, phosphorus pentoxide and potassium oxide were 8 kg to 9 kg, 4 kg to 5 kg and 7 kg to 8 kg per 667 m2 respectively, of which nitrogen fertilizer and potash fertilizer were 60% to 70% as the base fertilizer. Phosphate fertilizer is all basal. No panicle fertilizer was applied at the beginning or at the jointing stage of young panicle initiation; the dry nursery basal fertilizer accounted for 60% of the total amount of fertilizer, tiller fertilizer accounted for 20%, and grain fertilizer accounted for 20%; field planting combined with arable land per 667 square meters The farmyard fertilizers 1000 kg to 1500 kg, bicarbonate ammonia 50 kg, calcium superphosphate 25 kg, potassium chloride 4 kg to 5 kg, the ratio of Daejeon base fertilizer and top dressing is 4:6; the direct seeding field is in the 2-leaf stage and 4 During the leaf stage, urea and potassium fertilizers were applied to 3 kg to 5 kg for the tiller, and later the seedlings were supplemented with urea or potassium dihydrogen phosphate as the granulation fertilizer. Three days after the panicle was flushed to full ear, the perennial corn field was filled with grain per 667 square meters. 1 packet (50 grams) is sprayed on 50 kilograms of water.
2, water slurry management. Irrigation technology should be based on the use of water to regulate fertilizers, use water to regulate air, revitalize roots with roots, use roots to protect roots and preserve leaves. Use shallow water to turn green and wet tiller. Early rice began to be exposed or sunlit 15 days to 20 days after transplanting, and it was lightly sunned several times. After the spikes differentiated, they were watered and kept in shallow water layers. Footwaters were used for heading, dry and wet seeds were strong, and they remained wet to mature at the end of the harvest. About five days before and after the water cut, pest control
1, agricultural control. Efforts should be made to breed good varieties of disease-resistant pests, breed disease-free and strong seedlings, implement reasonable crop rotation, strengthen cultivation and management, timely transplant, formula fertilize, reasonably control water, promote early growth of rice, and increase plant resistance to pests and diseases.
2, biological control. Using the "duck-duck commensalism" ecological breeding technique, that is, every 10 to 12 feathered ducks stocked with 10 to 12 feathers per 667 square meters of paddy fields were fed for 42 days to 45 days. Ducks were reclaimed 15 to 18 days after the heading of rice, and the pests and diseases were significantly reduced.
3, physical control. 1 Using the characteristics of insect pests such as phototaxis, wave-like, and darkening, trapping and killing adults with frequency-vibration insecticidal lamps. 2 Set insect nets to obstruct adult. 3 Use sexual attractants to trap and kill pests. The use of synthetic syntheses with viscose, baits, etc., direct trapping adult worms or disturbing mating signals, so that pests can not find a spouse, reduce the rate of reproduction of pests.
4, chemical control. In chemical prevention and control, special attention should be paid to the timely, correct and scientific use of pesticides, and rice should be harvested in strict accordance with the reasonable and safe use of pesticides in order to reduce pesticide residues in rice. The use of Jinggangmycin to control sheath blight, the use of tricyclazole in the control of rice blast, rice bran, prevention and control of the second choice of vermouth, triazophos, insecticide double, insecticide list, prevention and control of the three chemical fertilizer selection , triazophos, butyl sulfide carbofuran, the use of imidacloprid, buprofezin in the control of rice planthoppers, control of rice leaf roller use Ruijinte, Le Siben (chlorpyrifos), Bacillus thuringiensis and other pesticides.
Sixth, 25 days to 30 days after harvesting the panicle, when the maturity reaches 90%, it will be collected according to varieties.
