二十三、结果期的中心任务是什么? 从第一条瓜坐住到拉秧为结果期,结果期愈长,产量愈高。结果期虽然营养生长和生殖生长同步进行,但光合作用产物往往大量运至果实,营养生长容易受抑制,因此,调节营养生长和生殖生长矛盾,防止病害发生和蔓延,延长结果期和叶片寿命,是这一阶段的中心任务。 Twenty-three, the results of the center of what is the task? From the first melon to live to pull the seedlings for the fruiting period, the longer the result, the higher the yield. Although the vegetative growth and reproductive growth are synchronous, the photosynthetic products tend to be transported to the fruits in bulk and the vegetative growth tends to be inhibited. Therefore, the conflict between vegetative and reproductive growth is regulated, the occurrence and spread of the diseases are prevented, the fruiting stage and the life span of the leaves are prolonged, Is the central task of this stage.
