In the autumn harvest season this year, the weather was fine and the late rice harvest was very smooth. However, because there was no rain in the past 20 days, the relative air temperature was small, the evaporation was large, the soil moisture was poor, and the drought was severe, resulting in the inability of double-low rape to move in time. plant. There will be a precipitation process at the end of the month. All localities must firmly seize this favorable opportunity to use the high standards and high quality of 5-7 days to do a good job in transplanting double-low rice field rapeseed.

First, a high standard of land preparation, deep trenches and narrow cars. For late paddy fields suitable for plowing, grab the plowing and cultivating the plate to achieve the matching of the three ditch, and the soil is crushed to the ground. For the late rice fields that are too late to plow, the paddy field must be transplanted to plant the plants and the ditch should be planted first. Gully and evenly spread on the surface of the car, and then hit the soil, fertilize and transplant on the surface of the car. For the muddy field, it is necessary to adopt the method of lifting the water from the deep ditch to lift the field and directly use the method of picking up the ditch. Gully shovel puts the smashed and flat surface. Ditch standard: Car width (bag ditch) 1m to 1.5m, car ditch 0.26m, ditch 0.4m, ditch 0.5m, so that the water can discharge, dark water filter.

Second, high standards of fertilization, do formula fertilization. Double-low rapeseed base fertilizer to be re-applied, according to the application of phosphorus and potassium fertilizers, will apply boron fertilizer, nitrogen fertilizer split application, phosphorus, potassium, boron one-time basis for the implementation of the principle; base fertilizer 1000 kg of farmyard manure (or cake 20 kg) Ammonium bicarbonate 40 kg, Superphosphate 30 kg, Potassium chloride 15 kg, U.S. Special Boron 0.2 kg, or farmyard fertilizer 1000 kg, compound fertilizer 50 kg, U.S. holding boron 0.2 kg, or farmyard fertilizer 1000 kg, rapeseed special fertilizer 40-50 kg. The best is a soil, a fertilizer, a seedling, a scoop of water, covered with thin soil and then planted seedlings.

Third, high standards transplanting, to achieve a reasonable close planting. For the seedlings without boron or with insufficient boron application, a 0.1% solution of Sonic Boron may be sprayed before transplanting, and 25 grams of Sulu boron powder may be sprayed with 25 grams per mu. According to the standard of 0.18 to 0.2 meters per plant, plant 4 rows per vehicle, ensure 8000-9000 strains per acre, transplant as much soil as possible, and pour enough water. For the lack of lyrics, we must establish a sense of annihilation and carry out water-fighting and drought-resistant transplants.

Fourth, adhere to chemical weeding, timely fertilizer to raise seedlings. In the field of grass-based weeds, weed herbicides such as high-efficiency herbicides can be used to spray the weeds at the 3-5 leaf stage. Fields based on broad-leaved weeds can be used well. The herbicides such as Shiduo and Kuusuke were applied at the 2-3 leaf stage of weeds; for the mixed weeds, Linke and Wangwang were used to control the herbicides. After transplanting and returning to live green, 20 tons of fresh water and urea plus 3-5 kg ​​of urea per acre were used as fertilization to promote seedlings with winter hair. Double-low rapeseed grows quickly, its leaves are green and susceptible to insect pests. Attention should be paid to the control of aphids and cabbage caterpillars.
