摘  要:
研究了不同灌水量对日光节能温室西葫芦生长、产量和土壤环境的影响。结果表明,与农民习惯灌溉量比较,灌溉量降低30%对西葫芦植株生长及产量没有显著影响;灌溉量降低50%影响植株前期生长和产量,对后期没有显著影响。降低灌溉量影响叶片和茎的干物质累积和单位面积的养分吸收,却提高了单位产量的养分吸收量。目前对于日光节能温室,农民习惯灌溉量的70%即可满足西葫芦生长需求。

摘  要:
The effects of irrigation amounts on growth,yield of pumpkin and soil environment were studied under conditions of solar greenhouse.Compared with those of farmer irrigation amount,70% of farmer irrigation amount had no significant influences on growth and yield of pumpkin;whereas 50% of farmer irrigation amount inhibited growth at the earlier growth stage and yield.Diminished irrigation amount decreased dry biomass of both leaves and stem together with N,P and K absorption per unit area.The result demonstrates that 70% of farmer irrigation amount can satisfy pumpkin water demand under conditions of solar greenhouse.
