以常见的10种叶菜类蔬菜为试材,通过立柱基质栽培形式,探究此形式对种植不同叶菜品种单位面积产量的影响,从而初步筛选出适宜高产品种。结果表明:定植到收获45d生长期,立柱不同层次之间叶菜产量存在差异,自上而下逐层产量主要呈现2种变化规律,先增加后降低和逐层递减趋势;立柱栽培形式下,小白菜、“京研”快菜、香菜、茴香、苔菜产量优于其它品种,小白菜和“京研”快菜产量分别达到14.15kg/m~2和11.08kg/m~2,香菜和茴香可以通过增大种植密度来提高单位面积产量,苔菜生长较快,叶长较大,鲜重约为小白菜的38%,对应干物重达到92%。生菜产量最低,“奶生一号”和“橡生三号”品种间没有显著差异。
Ten common leafy vegetables were used as test materials to study the effect of this form on the yield per unit area of different leafy vegetables cultivars through the column matrix cultivation form so as to screen the suitable high yielding varieties initially. The results showed that there were differences in the yield of leafy vegetables between the different layers of the column after 45 days of colonization. The top-down layer-by-layer yield mainly showed two kinds of changes, which firstly increased, then decreased and then decreased gradually. Under the column cultivation mode, The yield of cabbage, “Jingyan” fast food, coriander, fennel and moss was superior to those of other varieties. The output of cabbage and “Jingyan” fast food reached 14.15kg / m ~ 2 and 11.08kg / Coriander and fennel can increase the yield per unit area by increasing the planting density, the moss grows faster and the leaf length is larger, the fresh weight is about 38% of the cabbage and the corresponding dry weight is 92%. The lettuce output was the lowest, there was no significant difference between “milk number one” and “number three”.
