| 摘 要： | 系统研究了两个玉米(Zea mays L.)品种不同密度群体冠层内光合有效辐射、CO2浓度、温度、风速、相对湿度等小气候因子垂直分布及其变化。指出，密度能显著影响小气候因子在群体中的分布，并最终反映在群体的有效贮积能量上。通过合理密植能调节群体结构、充分利用小气候资源，获得较高有效贮积能量。

| Abstract: | The canopy microclimate of two ne w maize hybrids was studied under high yield condition in 1997-1998, farm-b ased field experiment in Jinan. Photosynthetic photon flux density (PPFD), CO 2 concentration, air temperature,and wind velocity were significantly affected b y plant density. The role of microclimate in affecting levels of available store d energy in grain was confirmed, and it is suggested that higher available store d energy could be obtained in grain by adjusting plant density and thereby adjus ting microclimate. |
