The Effect of Different Water Pressure of Alternate Micro-irrigation on Water Spinach Planted in Greenhouse
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.
