Rape is an annual or biennial herb of the family Brassica, which is an oil-rich oil crop. With the adjustment of the industrial structure and the favorable market prospects, the planting area of ​​rapeseed is expanding year by year, and the requirements for planting technology are also getting higher and higher. (1) Grasp the quality of autumn turning Brassica rapa is a conical root system with a deeper down bar, which is generally 40 to 50 cm deep. The deep, fertile, loose soil is conducive to the development of the root system, which can make the rapeseed root strong and Miaowang. Therefore, deep plowing more than 25 cm in the fall, combined with deep plowing for full-layer fertilization will not only be beneficial to water storage and soil conservation, promote soil maturation, improve soil structure, increase soil permeability, but also contribute to root growth. The full-layer fertilization can also meet the fertilizer demand during the whole growth period of rapeseed, especially in the period of maximum nutrient efficiency of the crop to meet the demand of high yield rapeseed nutrients. (2) Put a good seed quality 1 The selection of excellent, high-yielding varieties is a guarantee of high and stable crop yields. Seeds are full and tidy, with strong vitality, high yield performance, and they are neat and robust after sowing. The yields of Qingza l, Qingza 3, and the conventional varieties Qingyou 14 and Huaxie 1 are high, generally between 180 and 200 kg/mu, with a maximum of over 250 kg/mu, and the oil yield is as high as 42. % - 45 %, low erucic acid and glucosinolate content, good commercial performance, high yield and high quality varieties. 2 seed treatment before sowing with rape Seed Dressing seed dressing, rape can be neat and consistent seedling growth and robust. Mu with 1520 Ke Rui Jin Te seed dressing, can effectively prevent rape rape seedlings of the damage, in order to facilitate the normal growth of rape. (3) Put the quality of good sowing 1 The seeds of finely-prepared rapeseed are small, the weight of one thousand grains is between 3 and 4 grams, and it is also a dicotyledonous plant. The top soil capacity of seedlings is weak, and the requirements for soil preparation and soil moisture content are very strict. Therefore, the pre-sowing land preparation must meet the "Six-character" standard and ensure that all seedlings are broadcast. 2 Appropriate early sowing and improved sowing quality rapeseed is a strong cold-tolerant crop. When the monthly average temperature is stable at 24 degrees Celsius, the seeds can germinate, and the seedlings are also relatively cold-resistant. Generally, the seedlings will not be frozen at a low temperature of -3 degrees Celsius. . Especially in the shorter growth period of Zhaosuyi area should be suitable for early sowing, fight for a longer seedling growth period, the inflorescence and flower bud differentiation of rape, the number of pods per plant and the number of pods is extremely beneficial. The Zhaosu area is generally planted in early April. It should be shallow when planting. It should be suitable for 23 centimeters, 250-350 grams for irrigated land and 400-500 grams for dry land. When seeding, it is necessary to broadcast all seedlings, strive for Miao Qi Miao Zhuang, lay a good foundation for high yield. (4) Handle Field Management 1 Doing field rush work rapeseed seedling is the key to cultivating strong seedlings. The rape seedlings have a long time and grow slowly. The spring rape is about 40-50 days. At this stage, the weeds thrive and cannot be controlled in time, which will result in "Grass shortage seedlings" and "grass-grass seedlings" have caused poor rape growth and weak seedlings, resulting in reduced yields. Therefore, rape seedling must be early and small. Before the weeds 3-5 leaves, mechanized weeding of 15 kg of water can be achieved with 6.9% of Weibu 70 ml or 30 - 35 ml of Hibiscus per acre, which can effectively control dicotyledonous weeds such as wild oats; With 30-35 grams of vegetables and 30-40 grams of high-tech vegetables, Mu can be used to prevent broad-leaved weeds such as wild rapeseed and grey lee, creating a good environment for the growth of rapeseed. In the middle and late June, with artificial weeds, weeds were removed from the field to prevent weeds and crops from competing for light, heat, water, and fertilizers, promote robust growth of plants, increase branching, and lay a foundation for high yields. 2 The top-dressing rapeseed fertilizer and foliar fertilizer can grow fastest in the flowering period of the graveyard. In addition, the temperature rises, there is a huge root system, and the absorption ability of water and fertilizer is the strongest. It is the period when the rape needs the most fertilizer, and it is also the crop nutrition. In the period of maximum efficiency, the amount of fertilizer required accounts for about 50% of the total amount of fertilizer needed. Fertilizer is used at this time, and the efficiency of production increase is also the most significant. According to the fertilizer and water effect of crops, 58 kg of urea should be topdressed at the initial stage of convulsions to meet the demand of rapeseed for nutrients. Rape is very sensitive to boron nutrients. In the absence of boron, fertilization will be affected, causing rape to be "flowered", with lower seed setting rate or fuller kernels. Brassica napus varieties perform most. The application of boron fertilizer and other trace element fertilizers out of the roots during the bolting and flowering period can make the grain plump, increase the grain weight, and have a good effect on increasing the yield. 3 Good pest prevention and control work The main pests in the production base include venom, aphids, and stem weevil. The diseases include mainly powdery mildew, downy mildew, and sclerotinia. In addition to seed treatment for pest control, 800-fold dichlorvos, 1500-times sedan, or 1000-fold monocrotophos should be used to control seedlings at the seedling stage, and 500-fold more bacteria can be used for disease prevention and control. Ling or triadimefon is used to control downy mildew and powdery mildew, and 5000 to 7000 times or 1000 to 1500 times S. (5) Handle the harvest The economic output of rapeseed mainly comes from its fruit, and when the rape is mature, the pods are prone to bursting and the waste is very large at the time of harvest, and the loss of more than 15 kilograms of mu. In case of hail disaster, the loss will be even greater, and the heavy particles will be lost. The rape harvest must be done well. 1 The mature process of timely harvesting of rapeseed usually takes three stages: green-yellow stage, yellow ripe stage and ripening stage. The Zhaosu Sui area has a large planting area and mainly depends on mechanical harvesting. It should be harvested at the late yellow ripe stage and early mature stage. When harvesting, there must be a sense of urgency for harvesting grain, early harvest, and avoid hail disaster losses. 2 Reducing mechanical loss and wastage When the machine walks, the wood turning wheel should be adjusted to the slowest speed, about 110 rotations per minute. If the varieties are selected, they should be selected when they are mature or half awkward. The losses caused by wood turning wheels are relatively light. Upright variety losses are relatively large. When the moisture content is low, the time of harvest should be used during the early and late periods of resurgence, which can reduce the number of shatters and grain breakage. 3 Harvesting canola and semi-parasitic rapeseed can be harvested in the direction of lodging, which can reduce the loss of 50% of the grain loss and increase the yield and increase the efficiency.
