温室微润灌秋冬茬番茄适宜灌溉制度研究

Research on the Irrigation Regime of Tomato in Greenhouse under the Micro-moist Irrigation

通过田间小区试验研究了温室微润灌条件下秋冬茬番茄种植中土壤水分对番茄的产量、品质的影响。并基于试验数据采用主成分分析法对日光温室番茄的产量、水分利用效率、VC品质进行综合分析,初步确定了微润灌形式下番茄的适宜灌溉制度。结果表明:灌溉定额为336mm。在苗期灌水2次,灌水定额为18mm;在开花着果期灌水4次,灌水定额30mm;在结果盛期,灌水3次,灌水定额为35mm;在结果后期,灌水3次,灌水定额为25mm。

In this paper, the field experiment is carried out in order to study the effect of soil water on the yield, quality and watersaving efficiency of greenhouse tomato in the winter under the micro-moist irrigation. Based on the test data, the principal component analysis method is used to comprehensively analyze the yield, water use efficiency, VC quality. Finally, the tomato appropriate irri- gation regime is determined under the micro-moist irrigation. The result shows that the total irrigation water during the whole crop growing period is 336 mrrL In seedling stage, flowering and fruiting stage and the later fruiting stage, the irrigation times is two, four and three, respectively~ while the irrigation water quota is 18 mm, 30 mm and 35 mm, respectively.
