摘　　要：为明确不同质量灌溉水对大棚黄瓜生长和土壤电导率的影响,采用不同电导率的灌溉水E1(4.04 mS/cm)、E2(2.03 mS/cm)、E3(0.31 mS/cm)对大棚黄瓜进行灌溉。结果表明,黄瓜产量、株高、叶片数随灌溉水电导率的增加均显著降低;土壤电导率随灌溉水电导率的增加而增加,在0~40 cm土层,E1处理土壤电导率显著高于E2和E3处理47.3%~114.7%。可见在该研究区灌溉水是影响土壤电导率的重要因素,电导率为4.04 mS/cm的灌溉水已影响大棚黄瓜的生长,设施蔬菜种植需考虑灌溉水质量。In order to clarify the effects of different quality irrigation water on the growth and soil conductivity of greenhouse cucumber,this study used irrigation water E1(4.04 mS/cm),E2(2.03 mS/cm)and E3(0.31 mS/cm)with different conductivity to irrigate greenhouse cucumber.The results showed that the yield,plant height and leaf number of cucumber decreased significantly with the increase of irrigation water conductivity;The soil conductivity increased with the increase of irrigation water conductivity.In 0-40 cm soil layer,the soil conductivity of E1 treatment was significantly higher than that of E2 and E3 treatment by 47.3%-114.7%.It can be seen that irrigation water is an important factor affecting soil conductivity in this study area,irrigation water with conductivity of 4.04 mS/cm has affected the growth of greenhouse cucumber,irrigation water quality should be considered for vegetable planting in protected areas.
