摘　　要：研究了不同加气灌溉和灌水处理下温室番茄根区土壤环境及其产量的变化。结果表明,加气灌溉对土壤水分和温度影响不大,土壤含水率主要受灌水的影响,而土壤温度主要受气候的影响。加气灌溉能够明显提高温室番茄产量,且文丘里加气法和水气分离加气法处理的产量分别比未通气灌溉分别增加了30%和5%左右。高水且采用文丘里加气的水分利用效率以及干物质累积量均最大。温室番茄以高水且采用文丘里加气灌溉为宜。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 improvethe yield obviously, and the yields were improved by 30% and 5% under irrigation combined air and addingair after irrigation treatments compared to non-ventilation irrigation. Both water use efficiency and drymatter accumulation were the highest under the treatment of high water and irrigation combined air. Thetreatment of high water and irrigation combined air was recommended for tomato in greenhouse consideringtomato yield, biological accumulation and water use efficiency.
