The autumn and winter varieties of rapeseed are about to begin. According to the forecast of the China Meteorological Administration, a weak to moderate intensity La Niña event may occur this winter. The precipitation in September-October may be less than in previous years, and the soil moisture is poor. In particular, the Yunnan-Guizhou Plateau may have a severe drought. There is a drought in the sowing period and a drought in the seedling stage, and extreme cold temperatures may occur in the winter, which adversely affects the production of rapeseed. In view of the uncertainty of the pre-winter climate, in order to ensure the smooth development of autumn and winter sowing, the basis of high yield of rapeseed is put forward, and the technical guidance for winter rapeseed production in 2016/2017 is proposed for reference. First, the selection of high quality and high yield new varieties In recent years, the sclerotinia disease and lodging in the main producing areas of the Yangtze River have been seriously affected, which has affected the yield level. All producing areas should vigorously promote new varieties of "double low" and "three high" (high yield, high oil, high resistance) to improve the resistance of disease resistance and resilience. Fields using technical methods such as rice field machinery live broadcast, trenching and sowing, dry land cover and live broadcast should be selected from medium (early) varieties with antibacterial nuclear disease, lodging resistance, crack resistance and dense planting; For the field using cotton field nesting, paddy field transplanting, dryland transplanting and other technical models, it is advisable to choose medium-to-late (late) cooked rapeseed varieties with antibacterial nuclear disease, lodging resistance, strong individual development ability and high yield potential; The live rapeseed in the production area should be selected from the early-maturing varieties of antibacterial nuclear disease, lodging resistance, cold resistance, early flowering and early flowering. Second, grab the early broadcast seedlings In view of the possible autumn drought, measures such as rushing for early sowing, increasing density, soaking seeds and regulating irrigation and soaking can be taken to ensure that the rapeseed is fully seedling, early in life and early in development. In the middle rice paddy field or the dry seeding rapeseed, in the late September to early October, the seedlings will be sown in time after harvesting. The seeding amount is 200-300 grams per mu, and the seedlings are 20,000-30,000 plants. In mid-to-late October, sowing or lyrical The poor plot yields 300-400 grams of mu, and strengthens post-sowing suppression to promote seed swell and germination. In the Qiuyi area, drainage and weeding should be carried out as early as possible, and the sunny days should be broadcast in time. Transplanting and planting rapeseed, the seedling bed is planted in an amount of 500-600 grams per mu, and the seedlings can be sown and bred to cultivate large and strong seedlings. When transplanting, "one hole and two plants" can be used to ensure the planting density of 6000-8000 plants per acre in the field. When it is insufficient, it should be transplanted and planted with water. The field with high humidity in the field can be transplanted without any tillage in the narrow box. Rice-rice oil three-crop early-ripening rapeseed, the seeding amount of live seeding is 300-400 grams, and the density of mu is more than 40,000; the time of transplanting can be delayed by about 1 week compared with the medium-maturing variety, reducing the risk of early flowering and early flowering. Soaking seeds with a growth regulator such as Bibao before planting, then drying them, and sowing according to the conventional method can improve the emergence rate and drought resistance of rapeseed. Third, strengthen the prevention and control of pests and diseases in autumn and winter This year's drought and high temperature is more likely to focus on prevention of clubroot disease, cabbage caterpillars and mites. First, comprehensive prevention and treatment of clubroot disease. It is possible to reduce the risk by rotating crops, burning or deep-buried diseased plants, and applying 75-100 kg of lime powder to adjust soil pH, planting of ash and ash, and applying lime nitrogen and alkaline phosphate fertilizer. Acidic compound fertilizer, combined with Kejia or Dixon 500 times liquid to prevent chemical application. The second is to strengthen the monitoring and prevention of insects in autumn and winter. The aphids can be sprayed with 10% imidacloprid wettable powder 2500 times solution or 50% anti-converse wettable powder 3000-5000 times solution. In the seedling stage, the cabbage caterpillar and the diamondback moth are more harmful to the field, and the pyrethroid pesticide can be used for prevention and control. To prevent the prevention and control of the jumping armor near the forest land, it can be sprayed with 25% quetiapine emulsifiable concentrate 3000 times. The third is to promote physical and chemical integrated weeding technology. Before the transplanting, the rapeseed can be used to remove the grass by 50% acetochlor EC 50-75 g/50 kg spray before the seedling. The weeds in the seedling stage can be removed by the herbicide, quizalofop and double aid. Selective herbicides such as oil grass double grams, and strengthen cultivating and weeding. In the rice oil rotation area with manpower conditions, the straw can be covered in full after transplanting or direct seeding. The herbicide is not applied in the early stage, and chemical weeding is carried out according to the situation. Fourth, do a good job in water and fertilizer management and regulation Traditional method of fertilization, transplanting rapeseed can apply nitrogen fertilizer (N) 10-12 kg, phosphate fertilizer (P2O5) 3-4 kg, potassium fertilizer (K2O) 3-5 kg, borax 0.75 kg, of which 60% nitrogen fertilizer, 60% potassium fertilizer and All phosphate fertilizers and boron fertilizers were used as base fertilizers, and other 20%-30% nitrogen fertilizers were used for wintering seedlings, 10%-20% nitrogen fertilizers and 40% potassium fertilizers for fertilizers. The live rapeseed can reduce the nitrogen application rate to about 8 kg per mu. The dosage of phosphorus, potassium and boron fertilizer is the same as that of transplanting. 60% nitrogen fertilizer, all potassium, phosphorus and boron fertilizer are used as base fertilizer, and early topdressing is applied. Period of topdressing, before the winter, then look at the seedlings can be less appropriate to chase. In order to improve the efficiency of fertilization, it is recommended to apply special slow-release formula fertilizer for rapeseed, generally 50 kg per mu, transplanting rapeseed into the winter before re-applying about 5 kg of buds, and live rape can be chased in 3 leaves and 1 heart period. Apply 5 kg of urea, and look at the seedlings before entering the winter. The weaker rapeseed can be sprayed with Bishui and other growth regulators before winter to improve the resistance of rapeseed seedlings; the rapeseed grows prosperously, 30-40 g per acre before use, 15% paclobutrazol 40 The kilogram spray control promotes the growth of the rapeseed. In case of drought, it is best to use artificial watering. When the manpower is insufficient, the whole field can be used for irrigation. The water is not required to be on the surface; the un-dough field can be flooded, but it should be drained. Fifth, promote the multi-purpose development and utilization technology of rapeseed The promotion and application of multi-purpose development and utilization technologies for rapeseed oil and protein sources, feed, green manure, vegetables and ornamental crops should be strengthened. The first is to promote rapeseed green manure technology. It can increase soil organic matter, release insoluble phosphorus in soil, reduce the number of pests and diseases, and increase the yield of crops. The second is to develop the function of sightseeing tour of rapeseed. You can use different colors and other crops to design travel patterns and landscapes and develop canola tourism. The third is to promote the dual-use technology of vegetable oil. Choose a variety of rapeseed suitable for vegetables, pick up about 15 cm of vegetables and vegetables after twitching, not only taste good, but also rich in nutrients, can increase planting benefits. Picking rapeseed should be properly planted for 5-10 days, and 5 kg of nitrogen fertilizer should be applied after the picking. The fourth is to demonstrate the promotion of winter feed rapeseed technology. The forage yield and protein content of rapeseed are high. Harvesting vegetative bodies in winter and spring can alleviate the shortage of winter pasture and promote the development of animal husbandry.
