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。
研究瞭HMZ40型植物補光燈不同補光彊度對鼕季溫室茄子生長的影響。試驗結果錶明,鼕季溫室補光促進瞭茄子的光閤作用,茄子體內的葉綠素含量、淨光閤速率、胞間CO2濃度、氣孔導度均隨著光照彊度的增加而顯著增加;增加瞭茄子植株的長勢,促進瞭果實的髮育,隨著光照彊度的增加,株高、莖粗、葉麵積的相對生長量顯著增加,坐果率、果實縱徑與橫徑的生長速度均顯著增加。

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.
