| 摘 要： | 以"L402"为试材,研究了土壤水分对越冬番茄光合及蒸腾特性的影响.结果表明:越冬番茄全生育期内的Pn、Tr以50%处理最低,但65%和80%处理无显著差异,且均无光合午休;LWUE则以50%处理较高,80%处理最低.越冬番茄土壤水分管理以控制在65%为宜.

| Abstract: | Took "L402" as the test material,the effect of soil water content on tomato photosynthesis and transpiration characteristics were studied in different seasons.The result indicated that Pn and Tr of 50% soil water treatment were the lowest through winter.There were no difference between Pn and Tr of 65% treatment and them of 80% treatment,and both had not midday depression of photosynthesis.LWUE of 50% treatment was the highest through winter,and 80% was the lowest.So the 65% was the best water content throu... |
