摘　　要：为了筛选茄子控根容器栽培适宜的容器规格,利用30 cm×30 cm(直径×高度,下同)、40 cm×40 cm、40 cm×50 cm和50 cm×50 cm计4种规格的控根容器进行茄子栽培,研究了不同规格控根容器对茄子地上部和根系生长、根系活力、叶绿素含量、净光合速率和产量的影响。结果表明:大规格容器栽培,植株地上部和根系生长、净光合速率以及单株产量优势明显,但是降低了单位面积的种植密度,使得单位面积产量显著低于其他规格容器。综合考虑植株生长和产量,认为茄子控根容器栽培适宜的容器规格为40 cm×40 cm或40 cm×50 cm。In order to select suitable container size in the eggplant cultivation of the root-controlling container, eggplant cultivation experiment was performed in 30 crux30 cm （diameter×height） , 40 cm40 cm, 40 cm×50 cm and 50 cm×50 cm rootcontrolling container, cultivated eggplant shoot and root growth, root vigor, chlorophyll content, net photosynthetic rate and yield were analyzed and compared. The results showed that the larger container had more obvious advantages in shoot and root growth, root activity, chlorophyll content, the net photosynthetic rate and yield, but the plant density was limited due to the large container size, the yield per unit area was significantly lower than that of other specifications. Considering plant growth and yield, 40 cm×40 cm and 40 cm×50 cm container sizes were suitable for eggplant in the root-controlling container.
