Tree Planting Pit and Tree Planting Method in Plateau Area

Abstract

The invention discloses a plateau area tree planting pit and a tree planting method. The plateau area tree planting pit comprises a pit body and planting soil positioned inside the pit body, wherein the inner surface of the pit body is provided with a layer of slurry protection wall. The tree planting method is a planting method based on the planting pit. Through the slurry protection wall arranged on the inner surface of the pit body, on one hand, an effective insulating effect can be achieved at the earlier stage of tree growth, and rain water in the pit body, leakage of irrigation water and loss of fertility in the planting soil are reduced greatly; on the other hand, the slurry protection wall also plays a certain role in water seepage when water in the pit body is excessive, and trees are prevented from being flooded; moreover, root systems can penetrate through the slurry protection wall to grow continually along with the growth of the trees, the growth of trees is well promoted, and environmental pollution is prevented.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry planting, and in particular relates to a tree planting pit and a tree planting method in plateau areas. Background technique [0002] Due to the high altitude, dry and cold climate, long sunshine time and large evaporation, most of the soil in the plateau area has a short formation time and a low degree of maturity. ; and the soil organic matter content in plateau areas is low, even if there are a few lands that contain more humus, because the temperature is high during the day and low at night, microorganisms reproduce slowly, the number is small, and the decomposition is slow, and they are rarely absorbed by trees. Therefore, it is difficult to adapt to the planting requirements in plateau areas according to the planting soil nutrient index and planting pit technology stipulated in the relevant national regulations. Especially for the vegetation recovery area after the destruction of the...

AI Technical Summary

Problems solved by technology

Therefore, it is difficult to adapt to the planting requirements in plateau areas according to the planting soil nutrient indicators and planting pit technology stipulated in the current relevant national regulations.

Especially for the vegetation recovery area after the destruction of the engineering construction, the surface soil is completely destroyed, the soil is extremely barren, the planting through the existing planting pit has strong water permeability, and the performance of water and fertilizer retention is extremely poor

Trees and shrubs are planted in full accordance with the requirements of the current regulations, and the soil is improved. When the size of the planting pit, the backfill of the planting soil, and the planting and maintenance are all up to standard, it is difficult to survive. Even if it survives, the growth is difficult to meet the requirements.
