摘要
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60.8g/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。
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.
