摘要
为研究交替微润灌溉对植物生长的影响,在大棚内用土箱种植空心菜,将交替灌溉与微润灌溉相结合,以常规充分灌水作对照,共设置3组处理,重复试验2次,研究交替微润灌溉下不同压力水头对空心菜生长的影响。研究结果表明:不同灌溉处理对大棚空心菜的单叶叶面积、植株鲜重及植株含水率具有显著影响(p<0.05),对植株干重没有显著影响(p>0.05),交替微润灌溉能得到更高产量。在微润管埋深15 cm,微润管间距30 cm的条件下,1.0 m压力水头最有利于植物生长。
In order to study the effects of alternate micro-irrigation on the growth of plants, an experiment combined alternate irrigation with micro-irrigation was conducted in greenhouse. Including the conventional irrigation, the experiments set up 3 groups of treatment and repeated two times to study the effects of different water pressures on growth of water spinach. The results showed that different irrigation treatments had significant effect （P〈 0.05） on leaf area, plant fresh weight and plant water content, but had no significant effect on plant dry weight （P〉 0.05） ;alternating moistube irrigation could obtain higher yield; in the depth of 15 cm and the spacing of 30 cm, the water pressure of 1.0 m was the most favorable for plant growth.
