Autumn hair rape, the main use of 9 to 10 months of temperature, light, water resources, so that rape early robust. The standard for autumn hair rape is until the end of November, with 9 to 10 green leaves on the main stem and 12 to 13 green leaves on the winter solstice. To achieve this goal, we must earnestly grasp the "early, good, and fast" transplanting principle on the basis of timely sowing and nurturing strong seedlings. Grab the season early to transplant. The temperature is high, and the speed of rape leaves is fast. Generally, it takes 4 to 5 days for each new leaf to grow in October. It takes 5 to 7 days in November and 7 to 12 days in December. As a result, we must take advantage of the autumn seedlings of rape and must grab the seasonal transplants and strive for initiative. Autumn hair rape requires transplanting by October 20. Well that is suitable for transplanting good quality. First of all, it is necessary to select the right seedlings for proper planting. Generally, about 7000 strains per mu are planted in cotton fields, and 8,000 to 10,000 strains are planted in rice fields per acre. It is better to use a narrow line with a wide line and a good size. Second, we must carefully transplant and protect quality. When transplanting, it is necessary to “two guarantees†and “three beltsâ€. "Two-guarantee" refers to the preservation of the roots, the preservation of the leaves, the completeness of the root system, and the completeness of the blades. "Three belts" refers to belts, medicines, and mulching mud. About 1 day before transplanting, 1 “supplying manure†was performed to enhance the rooting ability and resilience of the seedlings, and 5-7 kg of urea was applied per acre. 2 to 3 days before transplanting, spray 1 time to “preserve the drug†to ensure that the seedling fitness “marriesâ€. One day before planting, the feet got up and started to raise water. The soil was raised and the root system was damaged. At the same time, to achieve "five no planting", that is not muddy seedlings, not overnight seedlings planted, not planted hanging root seedlings, planted seedlings are not mixed, do not grab sunny noon seedlings. Get up early and manage quickly. Fertilizers should be planted on the basis of enough base fertilizer or root fertilizer. When pouring the root water, 3 kg of urea is added per acre to promote early return to green and early living trees. After cultivating live trees, early cultivating and ground loosening can prevent soil compaction and promote root growth. In the late October, Mu catches 8 to 10 kilograms of urea, making it prosperous in November, expanding the nutrients and improving cold resistance. In addition, it is necessary to open a high standard of three ditch, after the rain stains, pay attention to water drought and seedling protection and strengthen the prevention of pests and diseases.
