The process requires great meticulousness. For instance, you can't use too much fertilizer, or the rice plants will easily fall over due to the weight of the leaves and grain being too much for the stalk. Whereas if you don't use enough fertilizer, the plants will lack nourishment and the yields will suffer.
而培育過程更是細心呵護，例如施肥量不能太高，否則容易「倒株」，也不能不足，否則營養不夠，不會長得漂亮。
