- 摘要:
- 以大叶菠菜为试材，在大棚内采用微润灌溉与分根区交替灌溉相结合的灌溉方法，研究了不同压力水头与微润管间距下，交替微润灌溉对菠菜生长状况的影响。结果表明：交替微润灌溉处理下，灌溉用水量是常规充分灌溉的64.6%~71.5%，且交替微润灌溉下植株根长、株高、鲜质量、干质量等指标皆高于常规灌溉。在微润管埋5 cm深的条件下，1.5 m压力水头、30 cm微润管间距处理植株生长状况较好，1.0 m压力水头、20 cm微润管间距处理水分利用率最高。因此交替微润灌溉不仅可以应用于大棚内菠菜种植，而且此灌溉方式在节约灌溉用水的同时可促进植株生长，提高产量。
- Abstract:
- Leaf spinach was used as test materials,and the methods of moistube irrigation and alternate partial root-zone irrigation were combined in greenhouse,the effect of alternate micro-irrigation on spinach growth under different pressure heads and micro pipe spacings were studied.The results showed that under alternate micro-irrigation,the irrigation water was 64.6%-71.5% of conventional irrigation.Under alternate micro-irrigation,the plant height,root length,fresh weight and dry weight were higher than that of conventional irrigation.Micro pipe was buried in the depth of 5 cm,under the treatment of micro pipe under 1.5 m pressure head,30 cm micro pipe spacing,spinach growth condition was better,under the treatment of 1.0 m head pressure and 20 cm micro pipe spacing,the water use efficiency was the highest.The conclusion was that alternate micro-irrigation could be applied to the cultivation of spinach in greenhouse,and this irrigation method could promote plant growth and yield while saving irrigation water.
