立柱式无土栽培就是将圆柱体竖立于地面。在圆柱表面种植植物,变传统的平面栽培为立体栽培。这种栽培法能大幅度提高单位平面上的种植量和收获量。单位平面上的种植量与立柱数量和立柱表面积成正比,但柱的数量不是越多越好,柱表面也不是越大越好。植物生长需要光照,植物采光情况是影响植物产品数量和质量的主要因素。如果设置合理的立柱密度,又根据植物品种特性定植适当株数,就能够在光资源不变的情况下,达到土地资源利用少,植物产品收获量高,经济效益好的目的。下面结合我们近几年的工作,对立柱式无土栽培作一简要介绍。
Column-type soilless cultivation is the cylinder erected on the ground. Planted plants on the cylindrical surface, change the traditional plane cultivation for three-dimensional cultivation. This cultivation method can significantly increase the amount of planting and harvest per unit area. The amount planted on a flat surface is proportional to the number of columns and the surface area of the column, but the greater the number of columns, the better the column surface and the larger the column surface. Plant growth requires light and plant lighting is a major factor affecting the quantity and quality of plant products. If set a reasonable column density, and planting the appropriate number of plants according to the characteristics of varieties of plants, will be able to change the light resources under the same circumstances, to achieve less land use of resources, plant products, high yield, good economic returns. The following combination of our work in recent years, the column of soilless culture for a brief introduction.
