When the plant N level was below 2%, the leaf starch accumulation kept stable, but the sugar content in leaf and starch content in lower layer leaf increased. When the plant N level was between 2. 0% and 2. 8%, the activity of SPS and leaf soluble sugar content were the greatest, which was favorable to the transportation of the accumulated matter from the leaf to the grain.

随植株氮水平提高，叶绿素总含量提高，但叶绿素b的提高速度快于叶绿素a；当植株叶片含氮率在2％以下时，随植株氮水平提高，水稻叶片淀粉积累不仅没有减少，相反叶片中的糖含量和下层叶的淀粉含量还有显著提高；当植株叶片含氮率在2.0％到2.8％的适宜水平时，叶片SPS酶活力和可溶性糖含量最高，有利于叶片中积累物质向籽粒转运。
