不同插植密度对寒地水稻叶片生长态势的影响研究

Research on the Effect of Transplanted Density on Leaf Growth in Cold Region Rice

通过对不同类型品种在不同插植条件下植株叶绿素含量、叶片大小、叶片存活率及叶面积指数等方面变化的试验调查,探讨研究了不同插植密度对寒地水稻生长态势的影响变化,以期为寒地水稻高产优质生产提供理论依据与实践经验。

Chlorophyll content, leaf size, survival rate of leaf and leaf-area-index（LAI） were investigated by different types of varieties on the different conditions of transplanted density. The test discussed the effect of different transplanted den-sity on growth to come up with the theory and practical experience for top-quality and high-yield paddy in cold region.
