| 摘 要： | 以东圣一号番茄为试验材料，初步研究了无压灌、滴灌和沟灌三种灌水方式对作物根区土壤水分条件、番茄的形态指标、水分生理指标和光合生理指标的影响。结果表明，无压灌溉通过调节作物根区土壤水分，优化了根冠比，提高了壮苗指数。无压灌溉和滴灌相对沟灌，减小了气孔导度和蒸腾失水，而光合速率并未降低，水分利用效率分别提高了51%和17.2%。

| Abstract: | With the experiment materials of No.1 Dongsheng Tomato,the paper preliminarily studied the impacts of tomato with different irrigation modes,such as non-pressure irrigation,drip irrigation and furrow irrigation,on the root zone soil moisture condition,morphological indexes,physiological indexes and photosynthetic physiological indexes.The results showed that through adjusting crops root zone soil moisture,non-pressure irrigation optimized the root/canopy ratio,increased the strong plant index;compared to furrow irrigation,non-pressure irrigation and drip irrigation reduced stomata conductance and transpiration loss without decrease of photosynthetic,and the WUE increased 51% and 17.2%,respectively. |
