The study was supported by National Nature Science Foundation of China of ""Biological foundation study of electrical indexes assessing tree vigor"". The mechanism of tree's leaf and stem capacitance and the application of electrical indexes under environmental stresses were studied. The main conclusions are summarized as following:(1) The leaf capacitance had significant positive correlations with leaf exosmosis electro conductivity, exosmosis percentage and leaf absolute moisture content, had significant negative correlations with leaf electrolyte electro conductivity and had no correlations with leaf relative water content.

本研究在国家自然科学基金"林木健康状况评价的电指标生物学基础"的支持下，对树体叶片电容和树体干部电容的机理及外界胁迫因素作用对树体电指标的影响进行了初步研究，研究的主要结论包括：(1)树木叶片电容与单位质量叶片离子外渗液电导率、叶片细胞离子外渗百分率及叶片绝对含水率呈显著的正相关关系，与单位质量叶片总电导率呈显著的负相关关系，与叶片相对含水率的相关性不显著。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.
