Effects of Aeration Irrigation on Soil Enviornment and Yield of Tomato in Greenhouse

The changes of soil environment in root zone and tomato yield were analyzed under different aeration irrigation modes and different water treatments.The results indicated that the effects of aeration irrigation on soil water content and soil temperature were little,soil water content was mainly affected by irrigation water amount while soil temperature was influenced by climate.Aeration irrigation could improve the yield obviously,and the yields were improved by 30%and 5%under irrigation combined air and adding air after irrigation treatments compared to non-ventilation irrigation.Both water use efficiency and dry matter accumulation were the highest under the treatment of high water and irrigation combined air.The treatment of high water and irrigation combined air was recommended for tomato in greenhouse considering tomato yield,biological accumulation and water use efficiency.
