Large-size coniferous tree nursery stock water-supplementing-free afforestation method in arid region

Abstract

The invention discloses a large-size coniferous tree nursery stock water-supplementing-free afforestation method in an arid region, and belongs to the technical field of barren mountain afforestationgreening in arid regions. The large-size coniferous tree nursery stock water-supplementing-free afforestation method in the arid region comprises the steps that fine soil preparation is carried out, and rain water is fully used; deep digging and deep planting are carried out, and underground water is fully utilized; branches of tree bodies are trimmed, and water of the tree bodies is retained; soil balls are reserved, and root systems are well protected; and barrier nets are well used for strictly preventing zokor harm. According to the method, the specifications of afforestation nursery stockare increased, the closing forest establishment time is shortened, and the afforestation greening quality is improved; water transporting for irrigation is not needed, it is guaranteed that the afforestation survival rate is not reduced, precious water resources and petroleum resources are effectively saved, and the afforestation cost is reduced; carbon emission is reduced, and green developmentis realized; and the harm of zokor and hare is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of afforestation and afforestation on barren hills in arid areas, and more specifically relates to a method for afforestation without water replenishment for large-sized coniferous seedlings in arid areas. Background technique [0002] In the afforestation and greening of barren hills in the arid area of ​​Northwest China, the common problem at present is that the seedlings for afforestation of coniferous tree species are small in size, and they dare not use large-sized seedlings, and they must generally be watered after planting. These two problems lead to the fact that the seedlings are small, rats and rabbits are serious, and the tree preservation rate is low, so it is difficult to close the forest; the second is that due to the need to pull water for irrigation, a large amount of water and oil are consumed, which not only pollutes the environment, but also exacerbates the The consumption of water and oil...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a method for afforestation of large-scale coniferous tree seedlings without water replenishment in arid areas, which solves the following problems: one is to solve the small size of seedlings for afforestation in barren hills, it is difficult to form a forest with canopy closure, and the quality of afforestation is not high; Coniferous trees need to be irrigated, which not only consumes fuel and water, but also increases the cost of afforestation; the third is to reduce carbon emissions; the fourth is to avoid the harm of pikas
