Plateau area tree planting pit and tree planting method

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 particularly relates to a tree planting pit and a tree planting method in a plateau area. Background technique [0002] Due to the high altitude, dry and cold climate, long sunshine time and large evaporation, most soils in the plateau area have a short formation time and a low degree of maturation. Moreover, the soil organic matter content in the plateau area is low, even if there is a small amount of land with more humus, due to the high temperature day and night, the microbial reproduction is slow, the number is small, the decomposition is slow, and it is rarely absorbed by trees. Therefore, it is difficult to adapt to the planting requirements in plateau areas according to the nutrient indicators of planting soil and planting pit technology stipulated in the relevant national norms. Especially for the vegetation restoration areas damaged by the construction, the surface s...

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.
