| 摘 要： | 研究了HMZ40型植物补光灯不同补光强度对冬季温室茄子生长的影响。试验结果表明，冬季温室补光促进了茄子的光合作用，茄子体内的叶绿素含量、净光合速率、胞间CO2浓度、气孔导度均随着光照强度的增加而显著增加；增加了茄子植株的长势，促进了果实的发育，随着光照强度的增加，株高、茎粗、叶面积的相对生长量显著增加，坐果率、果实纵径与横径的生长速度均显著增加。

| Abstract: | We used HMZ40 plant light-compensating lamp to study the effects of different lighting intensities on the growth of eggplant in winter greenhouse. The results showed that, the photosynthesis of eggplant was promoted by supplementary lighting, and the chlorophyll content, net photosynthetic rate, intercellular CO2 concentration and stomata conductance were all increased significantly when the supplementary lighting intensity was increased. In addition, the plant growth and fruit development were promoted by supplementary lighting, and the relative growth increments of plant height, stem width and leaf area were significantly increased, so did the fruit-setting rate and growth rates of fruit length and diameter, when the supplementary lighting intensity was increased. |
