Method and apparatus for vertical and inclined soilless planting

Abstract

Soilless culture method uses single or multiple step porous planting substrate which is capable of adsorbing nutritious liquid, is hung vertically or inclined, and has upper and lower parts soaked inside the containers of water or nutritious liquid so that it is humidified through the automatic downward flow of water or nutritious liquid to plant by means of siphonage, capillarity and gravity. In the present invention, plant roots in the planting base to absorb water and nutrients without anoxia and salt-gathering. The present invention can realize plantation and green city in relatively large scale and without consuming soil.

Description

technical field [0001] The invention relates to a soilless cultivation method and device, in particular to a soilless cultivation method and device for vertical and inclined surfaces. Background technique [0002] Because flowers, grasses and crops, like all green plants, have the ability to absorb solar radiation, dust, noise and harmful NH 4 , CO 2 , and SO 2 Therefore, greening work is a long-term systematic project to improve environmental conditions on a global scale. It is more important in cities in our country. Due to the small amount of greening area, industrial waste gas and automobile exhaust have seriously polluted the environment. Ordinary residents have suffered greatly. In order to improve the physical and mental health of the general public, it is an urgent task to improve the ecological environment and greening degree of the city. [0003] In a large and medium-sized city where every inch of land is expensive, the contradiction between the land area requ...

Problems solved by technology

This patent is basically still planting in a limited plane groove. The device of this patent has a complex structure, many consumables, a large project, high cost, difficult to promote in a large area, and inconvenient management; Cultivation, when the strong light irradiates the culture tank in summer, the temperature of the liquid will rise, and the roots of the plants will rot due to high temperature and lack of oxygen

[0006] Chinese patent No. is 94227004.5, and the patent name is the technology of " wall plant cultivation and water supply device ", and this device is the three-dimensional planting device that hangs some soil-containing cultivation pots on the wall. Large, to make full use of the three-dimensional wall for greening, a large number of pots and pots are needed, and management is difficult. It is quite difficult to implement this technology
