痕量灌溉管不同埋深对番茄生长、产量和水分利用效率的影响

为了探索日光温室番茄栽培时痕量灌溉管适宜埋深,以番茄仙客1号为试材,研究了春季日光温室栽培条件下,痕量灌溉管不同埋深对灌溉量、产量和品质的影响。试验结果表明,灌溉管埋深20cm和30cm处理与表面覆土相比,分别增产6.1%和15.2%,同时品质有所改善。灌溉管埋深10cm、20cm和30cm与表面覆土相比,耗水量分别降低15.7%、10.6%和5.7%,水分利用效率分别提高13.5%、19.6%和24.0%。灌溉管埋深30cm处理产量和水分利用效率最高。因此,灌溉管埋深30cm是本试验条件下日光温室春茬番茄较适宜的灌溉管埋设深度。

Effects of Trace Irrigation Pipe Depth on Development, Yield and Water Use Efficiency of Tomato in Solar Greenhouse

In order to explore the appropriate trace irrigation pipe depth,the effects of trace irrigation pipe depth on irrigation quantities,yield and fruit quality of spring tomato Xianke No.1 in solar greenhouse was studied.The results were as follow: Compared with the surface casing,when the trace irrigation pipe depth were in 20cm and 30cm depths,the yield increased by 6.1% and 15.2%,respectively.Compared with the surface casing,when the trace irrigation pipe depth were in 10cm,20cm and30cm depths,water consumption decreased by 15.7%,10.6% and 5.7%,respectively and water use efficiency increased by 13.5%,19.6% and 24.0%,respectively.Among all the trace irrigation pipe depths,the highest tomato yield and lower water consumption were in30cm depth.Therefore,trace irrigation pipe depth 30cm is the appropriate trace irrigation pipe depth of tomato in solar greenhouse.
