Rotary excavating and liquid injecting planting system and method for desertification control

Abstract

The invention discloses a rotary excavating and liquid injecting planting system and method for desertification control. Rotary excavating and liquid injecting devices are distributed in a planting area and connected through water pipes, and the water pipes are communicated with a liquid storage tank after being converged. Each rotary excavating and liquid injecting device comprises an outer cylinder and an inner cylinder, wherein the outer cylinder comprises a central outer cylinder body, hollow outer spiral blades are arranged on a cylinder wall and provided with outer permeation holes, the inner cylinder comprises a central inner cylinder body, hollow inner spiral blades are arranged on the cylinder wall and provided with inner permeation holes, the size of the inner spiral blades and the size of the outer spiral blades are matched, the hole opening positions of the inner permeation holes and the hole opening positions of the outer permeation holes are consistent, the central inner cylinder body is communicated with the liquid storage tank outside and placed in the central outer cylinder body, the inner spiral blades are placed in the outer spiral blades, liquid in the liquid storage tank permeates in planting pits when the cylinders are rotated to make the inner permeation holes and the outer permeation holes on the inner spiral blades and the outer spiral blades coincide, and the liquid stops permeating in the planting pits when the cylinders are rotated to make the inner permeation holes and the outer permeation holes staggered.

Description

technical field [0001] The invention relates to a soil or desert control system, in particular to a rotary digging liquid injection planting system and method suitable for planting pits, belonging to the greening desert technology. Background technique [0002] At present, the commonly used desert control methods include afforestation, grass squares, soil surface crusting technology, and microbial solidification technology. Afforestation is very difficult, the survival rate is very low, and the effect is slow; mechanical sand barriers such as grass grids can fix sand in the short term, but the long-term effect is not good; soil surface crusting technology uses chemical, physical or biological methods to form a certain thickness on the desert surface However, pure physical and chemical crusts are fragile and unstable, and chemical crusts also pollute the surrounding environment to a certain extent, while biological crusts have higher requirements on the environment, and the c...

Problems solved by technology

However, the current use of microbial technology is limited to the use of spraying methods to form a hard shell on the surface. For planting plants, a planting pit needs to be dug. Due to the particularity of the desert, this planting pit needs to be dug. It will not collapse holes, which will increase the cost of desert control virtually, especially for deserts with high fluidity, because of their migration and rapid expansion, the position of sand and soil is constantly changing, and it is more difficult to dig planting pits
