上海科研人员大面积推广立柱式栽培技术,使农作物获得大面积增产。 这一技术的特点是,将蔬菜、瓜果种在塑料立柱上的一个个洞口内,让根扎在海绵体上,作物通风好、光照足、生长快,并能节约大量土地。据介绍,立柱式栽培1亩地种植的作物相当于平面栽种的3倍。通过细 Shanghai researchers popularize large-scale column cultivation techniques to make large-scale crop production increase. The unique feature of this technology is that vegetables and fruits are planted in plastic openings in a hole to allow the roots to stick to the sponge. The crop is well ventilated, full of light and fast growth, and can save a lot of land. According to reports, the column cultivation of 1 mu of cultivated crops equivalent to three times the planted.
