A method for planting trees in arid and semi-arid areas

Abstract

The invention provides a method for tree planting in arid and semi-arid regions. The method comprises the following steps: 1, seed selection: selecting a tree species which is drought-resisting and suitable for local planting, and performing seed soaking and bud forcing treatment; 2, seeding: digging seed holes, wherein the soil which is dug out is mainly piled up on the north side of each seed hole to form a soil set which is inclined towards the inside of each hole; dibbling 3-5 tree seeds in each hole, meanwhile, putting in a soil wetting head of a movable underground drip irrigation emitter and filling soil for burial, connecting a water guiding hose with the movable underground drip irrigation emitter, and laying a water storing bag on the soil set on the north side of each seed hole to realize automatic drip irrigation on tree seeds; 3, plant fixing: leaving three seedlings in each hole in the first year and the second year, selecting weak seedlings to remove one in the third year, and removing another one after forming of trees in the fourth year; 4, management and protection: utilizing the movable underground drip irrigation emitters for watering, every time after watering, taking the drip irrigation emitters back in a centralized manner and well maintaining for next-time use, leaving the water guiding hoses and the soil wetting heads in the tree holes for repeated use, and taking back in a centralized manner in two years. According to the invention, the surviving rate of planted trees is high, water conservation is obvious, and labor, effort, time and money are saved.

Description

technical field [0001] The invention belongs to the technical field of afforestation, and in particular relates to a method for planting trees in arid and semi-arid areas. Background technique [0002] At present, tree planting methods in arid and semi-arid areas are all limited to planting trees. Due to the large amount of water evaporation and dry climate in arid and semi-arid areas, the survival rate of trees in traditional afforestation is very low, and trees are planted every year and die every year. Moreover, the newly transplanted trees need the root system to grow again and repair themselves in order to adapt to the soil climate environment and survive. The trees hardly grow in the year, which delays the forming time of the trees for one year. In addition, to plant a tree, you need to pour a bucket of water into the tree pit, which is about 20L-25L. To ensure the survival of the tree, you need to pour water three times at intervals, and the water for four waterings i...

Problems solved by technology

In addition, to plant a tree, you need to pour a bucket of water into the tree pit, which is about 20L-25L. To ensure the survival of the tree, you need to pour water three times at intervals, and the water for four waterings is about 80L-100L; The low survival rate of the tree is because the water is evaporated, air-dried and leaked to the ground before the root of the tree absorbs it.

Thirdly, planting a tree requires procedures such as seedling raising, seedling protection, quarantine, transportation, loading and unloading, digging, watering, and landfilling. Yu Yuan

In addition, the tree planting work can only be carried out in early winter and early spring, and the time and seasonality are extremely strong. If you miss the tree planting season, you cannot plant trees

It can be seen that planting trees is not the most effective way of afforestation in arid and semi-arid areas
