Seven key points for transplanting rapeseed, worth saving for growers

First, avoid transplanting in the rain. When it rains, the soil becomes waterlogged and airless. If you transplant in the rain, it easily causes red leaves and stunted seedlings in rapeseed, as well as root rot and seedling death. Therefore, it is best to choose a cloudy day or a sunny evening for transplanting rapeseed. This not only reduces the physiological water loss of rapeseed seedlings, but also helps them revive and survive after planting.

Second, lift the seedlings and transplant them on the same day. When transplanting, lift the seedlings and transplant them at the same time; lift only as many as you will plant, and do not plant seedlings that have been left overnight. This is because overnight seedlings consume more nutrients and water, which causes the seedlings to become soft and shrunken, revive slowly after planting, and be affected in early growth.

Third, transplant by grade and never mix grades. Since rapeseed seedlings vary in size and in vigor, in order to avoid the phenomenon of large seedlings bullying small seedlings and strong seedlings suppressing weak seedlings after planting, the seedlings must be carefully selected and transplanted by grade according to size and vigor. Never mix large and small seedlings together, so as to achieve uniform and strong seedlings.

Fourth, keep the roots straight, the seedlings upright, and plant them firmly. When transplanting rapeseed, place the rapeseed seedling against one side of the transplanting hole, keeping the roots straight, the seedling upright, and the leaves spread out. Then press the roots down with fine soil and water them thoroughly with "seedling revival water" so that the root system and soil are tightly combined, which helps absorb water and nutrients and improves the survival rate after planting.

Fifth, transplant with fertilizer. Apply a "send-off fertilizer" once 5-7 days before transplanting, so that the seedlings go into the main field with fertilizer, which helps them survive early, root early, and revive early after planting.

Sixth, transplant with soil. On the afternoon of the day before transplanting, water thoroughly with "seedling lifting water." On the day of transplanting, after the dew has dried, lift the seedlings with a small shovel, so as to damage the roots and leaves less and carry more soil, which helps them grow quickly after planting.

Seventh, avoid planting seedlings with pests or diseases. Spray a "starting medicine" once 2-3 days before lifting and transplanting. Generally, use a 40% dimethoate emulsifiable concentrate at 800-1000 times dilution to spray and kill aphids and other pests in the seedbed area. After lifting the seedlings, carefully pick out diseased seedlings and insect-damaged seedlings. This can both prevent seedlings from carrying insects into the main field and prevent viral disease infection.
