中文摘要:通过2010年—2011年秋冬季温室小区对比试验，研究了滴灌条件下秸秆生物反应堆对秋冬茬温室番茄的耗水特性及水分利用效率的影响，利用主成分分析法确定秸秆生物反应堆条件下秋冬茬温室番茄的适宜滴灌灌溉制度。结果表明：与对照处理相比，秸秆生物反应堆明显增加了番茄开花坐果期和结果期的耗水强度，其增幅分别为27.01%～50.50%和15.87%～76.32%。秸秆生物反应堆条件下的番茄产量明显高于对照区番茄，其增幅为18.38%～35.97%。水分利用效率亦表现出秸秆生物反应堆高于对照区的规律，其增幅为8.31%～29.08%。当土壤水分苗期在60%θf～70%θf、开花坐果期在70%θf～80%θf、结果期在70%θf～80%θf时，对提高果实产量和水分利用效率方面的促进作用较为明显。
Abstract:With a contrast experiment in greenhouse in autumn and winter of 2010 and 2011, this paper studied the influence of straw biological reactor on water use efficiency and water consumption intensity of greenhouse tomato in autumn-winter, and acquired an optional irrigation schedule on the basis of a principal components analysis. Results show that compared with control treatments, straw biological reactor significantly increases water consumption intensity of tomato in blossom-fruit stage and fruit stage with growth rates of 27.01%～50.50% and 15.87%～76.32% respectively; Tomato yield under the condition of straw biological reactor is significantly higher than that in contrast area with a growth rate of 18.38%～35.97%; Water use efficiency is also higher with a growth rate of 8.31%～29.08%; When soil moisture ranges from 60%θf to 70%θf in seedling stage, 70%θf to 80%θf in flowering & fruiting stage, 70%θf to 80%θf in fruiting stage, straw biological reactor has a significant effect on the increase of yield and water use efficiency.
