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。
In order to explore the suitable depth of trace irrigation pipe for tomato cultivation in greenhouse, tomato cyclamen No.1 was used as test material to study the effects of different irrigation depths on irrigation amount, yield and quality under solar greenhouse cultivation in spring . The test results show that the irrigation pipe depth 20cm and 30cm treatment compared with the surface soil cover, respectively, an increase of 6.1% and 15.2%, while improving the quality. Compared with the topsoil, the water consumption of irrigation pipes decreased by 15.7%, 10.6% and 5.7% respectively, and the water use efficiency increased by 13.5%, 19.6% and 24.0%, respectively. Irrigation pipe depth of 30cm processing output and water use efficiency of the highest. Therefore, the irrigation pipe depth 30cm under the conditions of the test spring greenhouse tomato irrigation pipe more suitable irrigation depth.
