Technique for Chemical Regulation of Direct-Seeded Rapeseed Before Overwintering to Cultivate Strong Seedlings
Chemical Regulation of Direct-Seeded Rapeseed Before Overwintering to Cultivate Strong Seedlings ⟦3 (Agricultural Wealth Network) Cultivating short, sturdy, and strong seedlings for overwintering is the foundation for high rapeseed yields. Paclobutrazol and uniconazole are broad-spectrum plant growth regulators. Using paclobutrazol or uniconazole to cultivate strong seedlings can enhance stress resistance and is an indispensable key technique. The methods for using paclobutrazol and uniconazole are: in mid-December, when direct-seeded rapeseed reaches the 4-leaf stage, use 50 grams of 15% paclobutrazol wettable powder per mu, diluted in 50 liters of water for foliar spraying; alternatively, use 11 grams of 5% uniconazole wettable powder, diluted in 50 liters of water for foliar spraying.

Key Points of Fertilizer and Water Management During the Spring Growth Stage of Direct-Seeded Rapeseed
Fertilizer and Water Management During the Spring Growth Stage of Direct-Seeded Rapeseed ⟦3 (Agricultural Wealth Network) 1. Apply bolting fertilizer early. The application rate of bolting fertilizer is generally about 10 kg of urea per mu. 2. Clear ditches and drain waterlogging. Excessive soil moisture will cause damage to all organs of the direct-seeded rapeseed plant, and is especially unfavorable to root growth and the maintenance of root vitality. Therefore, preventing waterlogging in spring is an important condition for ensuring stable spring growth of direct-seeded rapeseed, maintaining root vitality, controlling the occurrence of sclerotinia stem rot, and preventing premature senescence. The main measure for preventing waterlogging is to regularly clear the ditch systems inside and outside the field, keep the ditches unobstructed, and prevent standing water in the field after rain.
