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。 Under the condition of drip irrigation in sunlight greenhouse, the effects of irrigation quota and soil water stress on the yield of tomato during each growth and development period were analyzed. The drip irrigation and furrow irrigation of tomato two kinds of different irrigation methods, irrigation quotas were compared quantitatively. Drip irrigation effect was significantly higher than furrow irrigation. The best irrigation scheme of tomato drip irrigation was screened out.
