摘　　要：在日光温室滴灌条件下,分析了番茄各个生长发育时期的灌水定额及土壤水分胁迫对其产量的影响。对番茄滴灌与沟灌2种不同的灌水方式、灌溉定额进行了量化比较。滴灌的节水效果明显高于沟灌。筛选出了番茄滴灌最佳的灌溉方案。An experiment was carried out in a solar energy greenhouse to study the effects of irrigation norms and water stress at different growth stages on the yield of tomato. A comparative study of the desirable irrigation norms for drip irrigation and for furrow irrigation showed that drip irrigation was markedly superior to furrow irrigation for saving on water. An optimum drip irrigation regime was selected and recommended for tomato production.
