摘  要:
试验对温室番茄开花坐果期不同灌溉上限进行处理,结果表明:在灌溉上限为土壤相对含水量85%时,茎粗增长量、根系活力、净光合速率较大,土壤温度下降较小,蒸腾速率相对较低,水分利用效率提高,产量最高。

摘  要:
In this paper, by treating the greenhouse tomato with different Water irrigation maximums at its flowering and fruit-bearing stage, the results showed that growth of Stem diameter root activity and net photosynthesis rate were faster, Stronges and higher; the soil temperature drops less slowly, respiratory rate are lower while Water's effective utilization ratio improved and the yield reached the highest.
