Based on the mechanism of nitrogen transfer among different rice leaves, red edge slope and red edge position of the most upper and the 3rd expanded leaves were investigated specially. And using the two red edge parameters (red edge slope and red edge position), a new vegetation index (red edge curve shoulder angle vegetation index, abbreviation RSAVI) was calculated to detect rice nitrogen nutrition status.

基于氮素在水稻不同功能叶片之间运转规律的机理，文章重点分析了第一和第三完全展开叶红边斜率和红边位置的变化，并基于红边位置和红边斜率构建了一个新的植被指数（命名为&红边曲线肩夹角植被指数&，简称为RSAVI）监测水稻氮素营养状况。

Removal of the shoot apex and leaf wounding did not show any influences on nitrogen uptake by plant, but increased nicotine production per unit nitrogen.

切除顶芽和叶面损伤对烟株体内的氮浓度及吸氮量均无显著影响，但显著提高了烟株体内单位氮素产生烟碱的能力。

The semi-aerobic landfill can eliminate the pollution of nitrogen in the landfill by means of its self-disposal function in a shorter period within the laboratory simulated conditions. This supplies an important idea and way for solution to the problems of high concentration of ammonia nitrogen being difficult to treat in leachate in the middle and final stages.

在室内模拟条件下，准好氧填埋完全能够在较短的时间内利用自身的处理功能，去除垃圾中氮污染，这为解决传统填埋场中后期垃圾渗滤液氨氮浓度高、处理难的问题提供重要启示和有效途径。
