What does it mean to apply sufficient base fertilizer for transplanted rapeseed?

(Agricultural Wealth Network) Before transplanting, the soil must be finely and thoroughly tilled. Apply sufficient base fertilizer. The proportion of base fertilizer should account for about 30% to 40% of the total fertilizer application, mainly organic fertilizer, combined with nitrogen, phosphorus, and potassium fertilizers; phosphorus fertilizer and potassium fertilizer are best applied all at once in the base fertilizer. Organic fertilizer is loose and airy, has good water retention, and provides comprehensive fertilizer effects; it is beneficial both for soil improvement and for the growth of rapeseed roots.
