Three-dimensional planting, also called vertical cultivation, is a three-dimensional soilless cultivation. This cultivation is carried out by cylindrical cultivation erected in four weeks without affecting the plane cultivation, or by vertical gradient layering in the form of racking and hanging. To the space development, make full use of greenhouse space and solar energy, in order to improve the land utilization rate of 3 to 5 liters, can increase the output per unit area by 2 to 3 times.

  The characteristics of three-dimensional agriculture are concentrated in four aspects. One is “intensive”, that is, intensive management of land, reflecting the overall benefits of technology, labor, material and capital; second, “efficient”, that is, fully exploiting land, light energy and water resources. The potential of natural resources such as heat, while improving the utilization rate and utilization efficiency of artificial auxiliary energy; the third is “sustained”, that is, reducing the residues of harmful substances, improving the quality of the agricultural environment and ecological environment, enhancing the agricultural stamina and continuously improving the land ( Water) productivity; fourth, “safety”, that is, product and environmental safety, is reflected in the use of multi-species combination to simultaneously complete the restoration of contaminated soil and agricultural development, and establish a view of economic and environmental integration.
