| Abstract: |
| Based on mathematical statistics,this paper analyzes the effects of different soil moisture in greenhouse on eggplant growth,yield and water use efficiency under four different kinds of irrigation methods: furrow irrigation,drip irrigation,sub-irrigation and small tube flow irrigation. The results show that: The priority for selection of the four kinds of irrigation treatments is CT1>DT2>CT3>CT2.Among these treatments,in CT1 the sub-irrigation condition,when the soil moisture range is from 55%θf to 65%θf in blossom stage and fruit-set and from 65%θf to 75%θf in fruiting stage,the eggplants grow better;its yield increases by 17% compared with furrow irrigation.Moreover its water use efficiency is the highest,which are respectively 1.12 times,1.38 times and 1.37 times of other priority selected treatments. |
