| Abstract: | In order to solve the problems in greenhouse subirrigation ,a kind of sectional type of subirrigation tip was developed.Application results showed that,this sectional subirrigation tip has the characteristics of saving water effectively and cheap. The water use efficiency was two times of the common subirrigation tip. The irrigating water quota was 1225 5-1290m 3 ha -1 ,the degree of irrigation homogeneity was 0.75. The tomato output was 58680-59910kg ha -1 ,and the water efficiency was 46.44-47.88kg m -3 |
