栽培方式及光照条件对叶菜水培效果影响初探

Effect of Cultivation Modes and Light Conditions on Water Culture of Leaf Vegetables

以生菜及小白菜为试材,在简易泡沫槽及管道式水培模式下,探索其水培效果,并进一步在简易管道式水培模式下研究2种光照条件对叶菜生长的影响。结果表明:在同样生长条件下,2种模式水培的叶菜和基质栽培的产量差别并不显著,证实水培生产不影响这2种叶菜的产量;在2种光照条件下,生菜和小白菜都可以正常生长,可以形成一定的商品产量,但相较于200μmol/(m^2·s),100μmol/(m^2·s)光照更适合叶菜的生长,其生长量整体有较大的提升。

The effect of hydroponics on lettuce and Chinese cabbage was explored in the simple foam trough and pipeline hydroponic mode. The effects of two light conditions on the growth of leaf vegetables were further studied under the simple pipeline hydroponic mode. The results showed that under the same growth conditions, the yield difference between the water and substrate culture was not significant. It was proved that the production of hydroponic culture did not affect the yield of the two kinds of leaf vegetables, while both the lettuce and Chinese cabbage could grow normally under the two light conditions. However, compared with 200 μmol/（m^2·s）, 100 μmol/（m^2·s） was more suitable for the growth of leaf vegetables with a greater increase of growth.
