试验旨在探讨环境因子对番茄生长发育的影响，在温室内通过测定环境因子（温度、光照、土壤含水量）的变化研究其对番茄生长发育的影响。结果表明：当番茄生长发育处在高温环境(≥30℃)时，光照对番茄生长和果实发育产生的影响要高于土壤含水量，降低光照，可提高番茄的生长和果实发育的速度；土壤含水量和光照对叶绿素的合成均有影响，土壤含水量对叶绿素合成的影响更显著，3个品种中番茄叶绿素含量由高到低依次为：对照组＞遮阴组＞干旱组。
Abstract
To evaluate the effects of environmental factors on the biological characteristics of tomatoes in the greenhouse, the changes of environmental factors (temperature, light, soil moisture content) were determined. The results showed that the effect of light on tomatoes was higher than that of soil water content in the high-temperature environment (30℃ or higher). The speed of tomato growth and fruit development were improved in the case of lower light. The synthesis of chlorophyll was influenced in the soil moisture and light groups. Of the two groups, greater impact of soil water content on the synthesis of chlorophyll was observed. Of the three varieties, chlorophyll content was in descending order as follows: control groups> shade groups> drought groups.
