银川灌区控制灌溉条件下的水稻插植密度研究

Study on Densities of Transplantation of Rice under Water Controlling Irrigation Technology in Yinchuan Irrigated Area

通过在控制灌溉的条件下进行的水稻不同插植密度试验,得出了插植规格为30cm×13cm、每穴3苗、即插植密度为76.5万苗/hm2的水稻群体透光性最佳、叶面积系数最合理,为宁夏银川灌区控制灌溉条件下水稻旱育稀植栽培的最佳插植密度。

After the treatment of different densities of transplantation when use irrigation control technology, the results are as follows: transplanting standard is 30㎝×13㎝, 3 plants per cave, that is to say ,when the densities of transplantation is 76.5 thousand plants per hm2, the light penetration of the population and the leaf area indes are the best , that is the best density when use irrigation control technology in Yinchuan irrigated area.
