How to manage winter-grown strong seedlings? All the practical technical points are here
Winter-Grown Strong Seedling Management Techniques
(Agricultural Wealth Network) The first is to apply seedling fertilizer early. Applying seedling fertilizer early helps promote growth before winter under the relatively high temperatures of the early stage, achieving the high-yielding seedling vigor of winter-grown strong seedlings. Seedling fertilizer should be applied as early as possible, with nitrogen fertilizer as the main type. The second is frequent intertillage and early weeding. After the rapeseed survives transplanting, loosen the soil early, intertill frequently, break up hardened soil, loosen the soil, and raise soil temperature. About 30 days after rapeseed transplanting, when field weeds reach the 3 to 5 leaf stage, spray 5% quizalofop-p-ethyl emulsifiable concentrate and 10.8% haloxyfop-R-methyl on the surface to kill newly emerging weeds. The third is to clear ditches, earth up, check seedlings, and fill gaps.
