温室微润灌溉对黄瓜生长和产量的影响

微润灌水器是一种新型的微灌设备，为了更好地推广应用这一新技术，对微润灌溉和沟灌灌溉条件下，温室黄瓜生长和产量差异进行对比分析。研究结果表明，微润灌溉条件下棚内空气温度、土壤温度和空气湿度分别较沟灌灌溉增加9.6%、9.6%和降低4.4%；微润灌溉有利于黄瓜株高和茎粗生长，并增产4.4%，而各生育期日均耗水量均低于沟灌灌溉，全生育期耗水量仅为沟灌的54.9%，水分利用效率提高130%，达到60.8 g/kg。因此，微润灌水器在大棚蔬菜灌溉应用中具有节水增产的效果，能够提高经济效益，是适合大棚经济作物灌溉的新技术。

The Effect of Self-suction Micro-irrigation on Growth and Yield of Cucumis statirus L. in Greenhouse

Self-suction micro-irrigation is a new kind of micro-irrigation equipment. In order to prospect the better application of the new technology, in this paper, comparative analysis between self-suction micro-irrigation (SI) and furrow irrigation (FI) on growth and yield of Cucumis statirus L. was researched. Results showed that air temperature and soil temperature of the greenhouse under SI treatment both increased 9.6%, while air humidity decreased 4.4%; the SI treatment had a higher plant height and a larger stem diameter, besides that, it increased yield about 4.4%; meanwhile, daily water consumption of each growth stage was lowered and water consumption of entire period was about 54.9% of FI treatment; water use efficiency was promoted significantly under SI condition, it increased 130% and reached 60.8 g/kg. Therefore, since SI had a better working performance, saved water and increased yield, it is a suitable irrigation method for greenhouse.
