以“金石王子”番茄品种为试验材料,在四川春种栽培期间,采用避雨栽培方法,探讨了灌水量对番茄光合特性和产量的影响。结果表明:不同的灌水量对番茄光合参数、叶面积及产量有显著影响,在55%~85%的土壤含水量的避雨栽培中,随着灌水量的增加,番茄光合气体交换参数(光合速率、蒸腾速率)和叶面积均呈现增加的趋势,但叶片叶绿素含量无显著差异,光合速率、单叶面积与产量有显著的正相关性。
In order to test the effects of irrigation amount on the photosynthetic characteristics and yield of tomato, the method of rain shelter cultivation was adopted to study the prion varieties of “Jinshi Prince” and tomato cultivars. The results showed that different irrigation amounts had significant effects on photosynthetic parameters, leaf area and yield of tomato. In the rain shelter cultivation with 55% -85% soil moisture content, with the increase of irrigation amount, the photosynthetic gas exchange parameters Rate and transpiration rate) and leaf area all showed an increasing tendency, but there was no significant difference in leaf chlorophyll content. There was a significant positive correlation between photosynthetic rate, single leaf area and yield.
