Suitable soil and tree inlaying forestation method

Abstract

The invention discloses a suitable soil and tree inlaying forestation method, which comprises the following steps: firstly, analyzing and surveying different soil distributions in a forestation area according to the forestation area and selecting more than one tree seeds with different features for collocating according to different soil distributions; and then, preparing soil in a slope-separating counter-slope form and digging holes in separating slopes; and lastly, respectively sowing the selected tree seeds in different tree holes according to the soil classification, thereby finishing forestation. In the suitable soil and tree forestation manner, the survival rate of trees is greatly increased; the growth and development of the trees are boosted; and the tree cover degree and ecological repairing effect are increased. The method is strong in pertinence, simple and practical, low in cost, free from damaging environment and influencing the normal growth of the trees and especially suitable for application and usage in a loess plateau area.

Description

technical field [0001] The invention relates to an afforestation method, in particular to a mosaic afforestation method suitable for soil and trees, and belongs to the field of plant cultivation. Background technique [0002] The geological conditions of the Loess Plateau are complex, and the physical and chemical properties of soil are significantly different. These factors directly affect the growth and development of vegetation and landscape distribution, especially in hilly and gully areas. Generally, there are three types of soil mainly distributed in the loess hilly area: loess cotton soil, accounting for 77.5% of the total area; red clay, accounting for 5.6% of the total area; immature rocky soil with high sandstone content on the bedrock—weathered rock Mo soil, accounting for 9.0% of the total area. Among them, the loess soil layer is about 50-200m thick, and the red clay soil layer is 0.5-5m thick below it, and the weathered rock foam soil layer is 0.5-1m thick und...

Problems solved by technology

[0003] Scholars in my country have done a lot of research on the optimized model of flow-collection and drought-resistant afforestation technology in the Loess Plateau, caragana seedling planting afforestation technology, forest vegetation cultivation, rain harvesting afforestation principles, and the application of water-retaining agents in afforestation. progress, but these studies focus on the afforestation technology itself, lack of attention and analysis on the soil environment of artificial afforestation, especially the research on the use of natural precipitation and the application of chemical reagents is very active, and how to use different soil environments and carry out differentiated tree species collocation selection, but without sufficient consideration and research, the survival rate of artificial afforestation is generally low, and the progress of greening process is slow
