国内外常用的无土栽培系统主要是平面栽培，在进行叶菜类等植株矮小的作物栽培时，对空间利用率低，单位面积上的栽培面积小，限制了产量的提高。为此我们设计了一套柱式立体无土栽培系统，在本校试验站及兰州试验农场应用，效果较好，现报告如下：工系统组成和注运1．五拱棚为 At home and abroad commonly used soilless culture system is mainly plane cultivation, leafy vegetables and other plants in the cultivation of short plants, the low utilization of space, the cultivation area per unit area is small, limiting the yield increase. To this end, we designed a set of three-dimensional column soilless culture system, the experimental station in our school and Lanzhou test farm application, the effect is better, are as follows: System components and Note 1. Five Sheds for
