Effects Of Aerated Irrigation On Vegetative Growth And Fruit Quality Of Two Potted Fruit Trees

Taking potted Lycium Barbarum and Ficus carica as test materials, and using an aeration mode of three kinds of oxygen contents in water with2.9mg/L、4.0mg/L and6.0mg/L to water potted Lycium Barbarum and Ficus carica, the paper studied the effects of aerated irrigation on vegetative growth、 photosynthetic characteristics、fruit quality、the influence of soil nutrient and microorganism of potted Lycium Barbarum and Ficus carica. The study results as follows:1、The test increased oxygen inside the greenhouse irrigation water for ventilation when the atmospheric pressure is101KPa, and water temperature is25℃, the result showed that the relationship between the oxygen content and the aeration time in8L volume of water was:y=-0.0017x2+0.1405X+3.329.(R2=0.9509).2、When using three kinds of oxygen contents in water to deal with potted Lycium Barbarum, the growth performances were different. The oxygen content of4.0mg/L could promote the growth of plant height, new shoot length and leaf area of potted Lycium Barbarum, and increase the content of photosynthetic indexes, such as SPAD and Pn; It could also increase soil microbial quantity of potted Lycium Barbarum, it was conducive to the decomposition of soil nutrients, and promoted the growth of Lycium Barbarum, and then increased soluble sugar content of Lycium Barbarum fruit, it was conducive to the growth and development of potted Lycium Barbarum.3、When using three kinds of oxygen contents in water to deal with potted Ficus carica, the growth performances were different. The oxygen content of6.0mg/L could promote the growth of diameter and leaf area of potted Ficus carica, and increase the content of photosynthetic indexes, such as SPAD and Pn; It could also increase soil microbial quantity of potted Ficus carica, it was conducive to the decomposition of soil nutrients, and promoted the growth of Ficus carica, and then increased soluble sugar content of Ficus carica fruit, it was conducive to the growth and development of potted Ficus carica.
