A kind of anti-sand greening pile in saline-alkali land

Abstract

The invention discloses a saline land sand prevention greening pile comprising a pile body; the pile body is provided with a plurality of greening units; each green unit comprises a support plate used for supporting a greening pot, so the greening pile can green the saline land; the greening pile also comprises a sand prevention device and a controller; the sand prevention device comprises sand prevention shields matched with the greening units one by one; the sand prevention shield is arranged outside the greening pot; the sand prevention device also comprises a drive part used for driving the sand prevention shields to curve and unfold; when a dust sensor on the pile body senses the air sediment concentration is higher than a preset value, an electric signal is converted and sent to a signal processing circuit; the signal processing circuit receives the electric signal, and sends the electric signal to a central processing circuit; the central processing circuit controls the drive part, thus enabling the sand prevention shields to cover the greening units; the saline land sand prevention greening pile can cover the greening plants on the pile body, so the greening plants cannot be damaged by sands, thus ensuring plants greening effect.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land greening, in particular to sand-proof greening piles for saline-alkali land. Background technique [0002] With the development of the international situation, it has become an important task to build all parts of the country into green. Because saline-alkali land covers a large area in our country, and because saline-alkali soil is the general name of saline soil and alkaline soil, the soil salt content is too high (over 0.3%), which makes green plants difficult to grow or grow unhealthy, which leads to the greening of saline-alkali land. Difficulties to overcome. Especially in the saline-alkali land in coastal areas, many plants are damaged by the wind with sand, which greatly reduces the greening effect of plants. In view of the characteristics of the soil quality and climate of the saline-alkali land, it is necessary for those skilled in the art to design a device that can allow g...
