Hu Yu Village, Shahe Township, Yunmeng County: What is the red or dark green color of the leaves during seedling stage?
A: The normal rapeseed leaves are usually emerald green, while the leaves appear red or dark green, mostly caused by the lack of nitrogen and phosphorus in the base fertilizer. The “double low†rapeseed planted nowadays is mostly of the cabbage type, and the leaf color of the nitrogen-deficient plants at the seedling stage will turn reddish or deep red, because the nitrogen deficiency affects the formation of chlorophyll in the leaves and makes the anthocyanins more active. In the absence of phosphorus, the amount of roots absorbed by rapeseed is significantly reduced, the amount of absorbed fertilizer is weakened, the leaves are dark green, and some are dark purple, followed by withering, flower bud differentiation is blocked, the amount of flowers is small, and the number of pods is small. The countermeasures are to apply appropriate amount of nitrogen fertilizer and phosphate fertilizer in the base fertilizer, or to apply about 1000 kilograms of decomposed human excrement per acre before wintering.
