The autumn sow rapeseed focuses on the promotion of light-weight no-tillage cultivation techniques, which mainly promotes the techniques of rice transplanting, no-tillage transplanting and rapeseed cultivation, rice seedlings cultivation with no-tillage and direct seeding techniques, and no-tillage direct seeding and transplanting techniques for cottonseed rapeseed. To promote rapeseed no-tillage technology, invest 10 yuan per acre to get rid of grass and eliminate traces of green, save investment 40-50 yuan farming fees, technical operations in place, rape can also increase production 5-10%, all localities must vigorously do this to improve labor efficiency Enhance the major technological reforms that have a lasting effect on agricultural development, promote the increase of rapeseed yield, increase the cost of agriculture, and increase farmers' income. Specific operating points: Rice transplanting rapeseed no-tillage: 1, use double-low rapeseed varieties, cultivation of strong seedlings. 2. Drain the water in the field about 10 days before the rice is harvested and reach the standard of basically no seal when harvesting. 3, ditch the whole room, grab the sunny immediately after the completion of the "three ditch", gully scatter sprinkled in the car. 4, 1 to 2 days before transplanting rape, with a trace of 200 ml per mu, about 60 ml of Jinduer, 50 ml per barrel of water, and 15ml of Jinduer, evenly spray the field. For weeds, apply base fertilizer and boron fertilizer as required after 24 hours, then cover the straw. 5, transplanting rapeseed, when transplanting rapeseed fields should have a bottom hoe, in case of drought should be filled with a horse water, after the conventional rapeseed field management operations. (2) Rice seedlings with no-tillage and direct seeding: 1. Premature cornices: mid-season rice, early-maturing late rice pods, and live rapeseed (1) The field water is drained 10 days before the rice is harvested, and the standard of footless printing is basically achieved at the time of harvesting. (2) Ditching the whole compartment, immediately after the harvest, do a good job of “three ditchâ€, and the ditch is scattered in the car. (3) Before the live broadcast, use a trace of 200 ml per mu, add 50 ml of water per barrel, and spray the field weeds evenly. After 24 hours, apply base fertilizer and boron fertilizer. (4) Live broadcast, sowing from mid-September to October 5th, the rapeseed should be planted in a reasonable density, 1.5-18 thousand plants per acre, sowing rate should be controlled when planting, 0.3 pound per acre per acre so as to ensure the planting Evenly, 0.7 pounds of fried commercial rapeseed can be used per mu, plus 0.3 pounds of rapeseed seeds are evenly mixed. After sowing, the plants are weighed and sown. No pods or drought are encountered. The rapeseed water is preferably fed once before sowing and the straw is covered after sowing. (5) When the rapeseed grows to 3 leaves and 1 heart, the field weeds are weeded with conventional herbicides, and then they are operated according to conventional rapeseed field management. 2. Late-ripening mouthwash: Late-maturing late-cocoon, late-season rice-rice, interplanting rapeseed with rice forest. (1) About 10 days before the rice is harvested, “ditch ditch†and “waist sluice†are drained and put on the field. About 7 days before harvest, the field can be planted in a hard and moist mud and broadcasted before October 20. (2) After raining the forest, or combined with irrigation and horse water to apply drought to the base fertilizer, base fertilizer application of rapeseed special fertilizer or bb fertilizer and boron fertilizer, no-tillage rapeseed direct use of ammonia nitrogen as a base fertilizer, so as not to cause burning buds sprouting. (3) Rape should be cleared after the canola is out of the forest, so that it can discharge energy and rain and dry it. (4) Preventing weeds, weeds are one of the main disasters of live rapeseed, and we use 5% “Golden State g†EC or 12.5% ​​“Gaisengeng†EC 50ml in water after the emergence of weeds. 30 kg, evenly sprayed on the surface of weed stems and leaves in the morning or evening, can control a variety of grass weeds. (5) After entering the conventional rapeseed field management operations. <3> Live-breeding or transplanting of cottonseed rape with no-tillage: 1. Select double-low rapeseed varieties and cultivate strong seedlings. 2. One or two days before the rapeseed direct seeding or transplanting, use 300 grams of traceless fertilizer to spray evenly on the cotton plants and the lower weeds. After 24 hours, the cotton can be pushed and ridged and fertilized. 3, rape live or transplanting, no time or drought is best to fill a horse water. The live rape 3 leaves 1 heart is used to weed with conventional herbicides, and later into conventional rapeseed field management operations. Rapeseed grows no cotton or rice after harvest.
