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.
