Hypoxia causes injury and yield loss. Soil aeration has been reported to accelerate the growth of plants and increase crop yield. The aim of this study was to examine growth response of greenhouse-produced muskmelon to 3 levels of sub-surface drip irrigation (I), 3 different installation depths of drip laterals in the soil (D), and 4 levels of supplemental soil aeration frequency (A). A fractional factorial experiment was designed to examine these treatment effects on marketable fresh fruit yield, leaf area index during 3 growth stages, and dry matter partitioning at harvest. In addition, we studied the response of fruit yield and dry matter of tomato to 2 levels of burial depths of subsurface tubing in combination with 3 frequency levels of soil aeration. Results showed that soil aeration can positively influence the yield, leaf area index, dry matter and irrigation use efficiency of the muskmelon (p < 0.05). The fruit yield of muskmelon and tomato were increased by 21.5 and 30.8% respectively with 1-d and 2-d aeration intervals compared with the no aeration treatment. The results suggest that soil aeration can positively impact the plant root zone environment and more benefits can be obtained with aeration for both muskmelon and tomato plants.

温室生产的甜瓜和番茄对地下滴灌和土壤通气管理因子的生长响应

缺氧会导致伤害和产量损失。据报道，土壤通气可以加速植物的生长并增加农作物的产量。本研究的目的是研究温室生产的甜瓜对3种地下滴灌（I），3种不同滴灌支管在土壤中的安装深度（D）以及4种补充土壤通气频率的生长响应（一种）。设计了分数阶乘实验，以检验这些处理对可销售的新鲜水果产量，三个生育阶段的叶面积指数以及收获时干物质分配的影响。此外，我们研究了番茄的果实产量和干物质对地下管道的2个埋藏深度以及3种频率的土壤通气的响应。结果表明，土壤通气可以积极影响产量，叶面积指数，甜瓜的干物质和灌溉利用效率（p <0.05）。与不通气处理相比，以1天和2天通气间隔，甜瓜和番茄的水果产量分别增加21.5和30.8％。结果表明，土壤通气可以对植物根部区域环境产生积极影响，并且通透性可以使甜瓜和番茄植物获得更多益处。
