摘  要:
以生菜品种"北京101"和"皇帝"为试材,以常规滴灌和减量滴灌为对照,研究了痕量灌溉系统对日光温室生菜生长、产量和水分利用效率的影响。结果表明:与常规滴灌相比,低痕量和高痕量灌溉不影响生菜的株高、单株外叶重和单株净菜干重;单株净菜鲜重、单株根鲜重/干重、经济产量和地上生物量以常规滴灌最高,但与痕量灌溉无显著差异;低痕量灌溉水分利用效率最高,较其它处理提高8.2~30.7kg/m3。

摘  要:
Taking lettuce 'Beijing 101' and 'Emperor' as materials,using conventional and reduced rate of drip irrigation as control,the effects of first generation trace irrigation system on growth,yield and water use efficiency of lettuce were studied.The results showed that plant height,leave weight of out layers and dry weight per plant of lettuce could not be affected by the trace irrigation treatment.Fresh and dry root weight,economic yield and biomass weight above ground were the highest under the conventional drip irrigation treatment,however,there was no significant difference between conventional drip irrigation treatment and trace irrigation treatment.Water use efficiency in low trace irrigation treatment could increased by 8.2~30.7 kg/m3 compared with the other treatments.
