2, early nursery. Rape strong seedlings age about 40 days, reaching more than 6 true leaves, due to the time required to close the rapeseed rape, in order not to misuse agricultural time, should be based on the harvest time of the previous crop, the seeding period of the seedlings. Usually around September 15.
3, timely transplanting. General width of 47 cm, narrow line of 33 cm, hole depth of 4 to 5 cm, the hole distance with the density, generally 800-12000 per acre density transplanting is appropriate, transplanting seedlings close to the hole wall, do Miao Zhenggeng, with nitrogen, phosphorus, potassium, boron fertilizer and organic fertilizer with root pressure, and timely pouring root water. Or after the whole field is planted, it will help the early living plants of rape and early emergence of seedlings. If we encounter continuous rainy weather, we must assault the plate field to open the ditch, eliminate surface water in time, and strengthen the management of the paddy field to reduce the height of the young plant. When the paddy field reaches the transplanting requirement, immediately plant rape. Once the emergence of seedlings and other fields formed a tall planted seedling, the high-foot part should be buried deep in the soil during transplanting, which will help prevent freezing damage and lodging. If long-term drought is encountered during the transplanting of plateau rapeseed, it is possible to fill the paddy fields with horse water once and allow the fields to be moistened and transplanted at appropriate times. After transplanting, dry weather is best to use Xianggou water for irrigation.
4, cultivator, fertilization, weeding. Early application of rapeseed nitrogen, phosphorus, potassium ternary compound fertilizer, 30-40 kilograms per mu, organic fertilizer 3000 kilograms per mu, or spread them as a base fertilizer before the ditch spread on the surface of the car, with the help of mechanical trenching The effect is to swirl the ditch on the surface of the car and bury the manure. As there is no ploughing in no-tillage rape fields, the soil is relatively compacted and there are many weeds. Therefore, we must use artificial cultivating and weeding at the seedling stage. The cultivator must be first shallow and deep, and usually 2-3 times cultivating, eliminate weeds, loosen the soil, and promote Root growth. In the event of severe grass shortage, safe herbicides can also be sprayed. In the mono- and dicotyledonous annual field, one can use 50% paracetamol 100 g plus 12.5% ​​Gaixin 30-50 ml/mu or glyphosate 1 to 3 days before transplanting. 200 ml of water is 50-60 kg, evenly sprayed on the surface of the soil; or within 3 days after transplanting, 50 kg of active amide is used to spray the water. In the field of monocotyledonous weeds (such as aphrodisias), after transplanting to survive, weeds 2-3 leaf stage, mu with 12.5% ​​cover grass can 40-50 ml, water 50-60k kg Spraying on weeds between rows can control rapeseed field weeds.
5, as early as possible to promote early management, soil anti-loft. In the fertilization, the first time after planting, the plant was treated with water, the second was to raise the seedlings early after returning to survival, the third was to re-open the fertilizer, and the fourth was to see the seedlings apply Shilei moss fertilizer. Before the whole field rapeseed line, combined with topdressing to prevent late lodging. Shallow depth first, that is, the first time after the live tree is shallow, gradually deepens later, to the overwintering stage up to 5-6 cm, to promote the root bar. The cultivator loosens the soil and roots to prevent weeds and lodging later.
6, comprehensive prevention and control of pests and diseases. In the later period, it will be able to clear the ditch, reduce the humidity in the field, and reduce the occurrence of pests and diseases. The seedling stage focuses on the control of aphids and cabbage caterpillars, which can be controlled by major heroin and insecticide nets. The flowering period focuses on the control of Sclerotinia sclerotiorum. It can spray 35% sclerotium light 75-100g or 25% at the beginning of flowering and full flowering period to spray 100g of EC 50ml to 50kg of water. It can also use 40% sclerotia net and g Bacillin and other agents prevent and control 7-10 days to prevent the second sclerotia.
7, suitable for harvesting. Appropriate harvest period is when the field is about 80% of the silt is pale yellow or most of the stalks of the main grain are dark brown when harvested.
Rape No-tillage Transplanting Machine Ditching Supporting Technology
1, Qinggou drainage, mechanized open car ditch. Demands rice to be drained and dried in time. From the end of September to the beginning of October, rice piles will be retained 15 to 25cm after harvest, using the matching machinery to open the roadway. The standard is 25cm wide, 20cm deep, and 1.8m wide. The mechanical model can choose 1K-35 type rear adjustable trenching machine produced by Jiangsu Yancheng Agricultural Machinery Plant No. 2 or the 1KL-18 type trenching and creping machine manufactured by Dongwu Machinery Factory of Guangde County. The former is equipped with power machinery as 25 horsepower steering wheel tractor; the latter is a 12-15 horsepower walking tractor, and the average production efficiency can open 2-2.5 mu per hour.
