水稻叶片是水稻一生进行光合作用的重要器官,叶片生长的多少、好坏,对分蘗多少和产量高低,关系极为重大。本试验旨在通过人为损毁叶片的轻重程度,来观察其对分蘗动态与产量构成的影响,并阐明叶片的功能,从而使生产上重视、保护、促进叶片的正常生长,达到高产的目的。 Rice leaves are important organs of rice photosynthesis, the growth of leaves how much, good or bad, the number of tillers and the level of output is extremely important. The purpose of this experiment is to observe the effect of the damage on the tillering dynamics and the yield composition by artificially damaging the leaves, and to elucidate the function of the leaves so that the production can attach importance to, protect and promote the normal growth of the leaves to achieve high yield.
