The seeder has the functions of shallow ploughing and mulching, applying base fertilizer, digging the rickshaw, sowing, and covering the soil and the like, and can be directly planted on the uncultivated land. Usually sowing 6-10 acres per hour.
Second, select the fine varieties: choose the main push of the city's Zhongyou hybrid 7819, Huayou hybrid 1 2, Huayou hybrid 1 5, oyster oil 5 2 0, Sheng oil 868, the earth 55, oyster oil 5103, Nanyouza 1, etc. High-quality double-low rapeseed varieties. A village adopts the same variety of rapeseed and concentrates on planting. It is not appropriate to rotate with other materials of cruciferous plants. The amount of mu should be controlled within 300 grams.
Third, fine sowing 1, suitable sowing: rapeseed machinery straight (strip) broadcast general sowing period is from September 15 to November 10, suitable sowing date from September 15 to October 25. Should choose the former crops gargle the earlier blocks, that is, corn fields, sesame fields, soybean fields, rice fields, etc., the earlier the sowing date, the higher the yield, otherwise it will affect the yield. 2. The residual height of the former crop should be below 20cm. 3, the amount of seedling needs to be adjusted to the minimum. 4, the use of base fertilizer should use poor water absorption of granular fertilizer. Mushi compound (mixed) fertilizer 40-50 kg and 300 grams of boron. 4, sowing depth should be controlled between 2-3cm, too deep and shallow affect the seedling after sowing. 5, the seeder operation (advance) can not be free to stop, the operation speed should not be too fast, when the seeder is not lifted up, can not be retrogressed, equipment turning should not be too hasty.
Fourth, do a good field management 1, chemical weeding: two chemical weeding: the first time after the end of sowing a closed weeding (spray chemical herbicides); the second time before the Spring Festival a field of chemical weeding. 2. Drought-resistant seedlings: In case of drought after sowing, irrigation is needed to ensure the seedling emergence rate. The irrigation standard is 3cm below the ditch to the surface of the car. After the car is wet, the irrigation is stopped immediately. 3, pest control: prevention and treatment of seedling buds, cabbage caterpillars and other pests. 4, a reasonable close planting: uniform seedlings, transfer dense and thin, in order to facilitate the rape ventilation, light transmission. 5. Top dressing and chemical modification: Topdressing and chemical regulation in 3 leaves, 10-15 kg of urea in top dressing, 15% paclobutrazol in 50 grams of water, 80 jin in water, control of tall seedlings, and improvement of seedling quality . 6, other field management measures with the general rapeseed management.
