以桶式II型无土栽培装置为对照,桶式无土栽培新装置为处理,研究了一种桶式无土栽培新装置根区环境温湿度的变化以及根系生长状况的试验,结果表明,新装置栽培下,基质的温湿度变化的幅度均低于对照,气室中温湿度变化的也低于对照,但两种装置栽培下其温湿度变化的趋势总体上基本一致。苗期植株鲜重和根长没有明显差异,果实成熟期地上鲜重和根长差异显著,新装置明显高于对照。
Taking barrel type II soilless culture device as control, a new bucketless soilless cultivation device was used to treat and study the change of temperature and humidity in the rootzone of a new barrelless soilless culture device and the experiment of root growth. Under the new plant cultivation, the changes of temperature and humidity of the substrate were lower than those of the control. The changes of the temperature and humidity in the air chamber were also lower than those of the control. However, the trend of the temperature and humidity of the two plants was basically the same. There was no significant difference between fresh weight and root length at seedling stage. The fresh weight and root length of fruit at maturity were significantly different, and the new device was significantly higher than the control.
