Method for rapidly and efficiently increasing survival rate of nursery stock afforestation

Abstract

The invention provides a method for rapidly and efficiently increasing the survival rate of nursery stock afforestation, and relates to the field of restoration ecology and forestry. The method comprises three stages of nursery land seedling raising, air root cutting seedling raising and rainy season afforestation technology implementation and management. In the first stage, nursery land seedling raising comprises the steps of seed pretreatment, soil preparation, sowing and seedling stage management; in the second stage, the seedlings obtained in the first stage are cultivated through an air root cutting container, fine management is conducted, lateral root growth is promoted, and afforestation is conducted after the seedling vigor is recovered; and in the third stage: rainy season afforestation technology implementation and management comprise micro-terrain soil preparation, meadow laying and nursery stock management and protection measures, the micro-terrain soil preparation is carried out on the afforestation land in the stage, the rainy season is selected according to the site condition and rainfall condition of the afforestation land, the robust seedlings cultivated in the previous two stages are transplanted with soil to the afforestation land, and the survival rate of the afforestation nursery stocks is increased in combination with the nursery stock management and protection measures.

Description

technical field [0001] The invention relates to the fields of restoration ecology and forestry, in particular to a method for rapidly and efficiently improving the survival rate of seedling afforestation. Background technique [0002] Afforestation is an effective means to accelerate the process of vegetation restoration, and it is the most traditional and widely used construction method. Excellent individual seedlings are the basis for building a healthy and sustainable forest ecosystem. However, when the seedlings are transplanted or transported from the nursery to the afforestation site, the root system is often susceptible to damage or loss, resulting in unsound root development and function, reducing the quality of the seedlings, limiting the survival and growth of the seedlings after afforestation, and hindering the degraded ecosystem. Restoration and reconstruction, especially for extensive arid and semi-arid regions. Cultivating an excellent root system is the key ...

AI Technical Summary

Problems solved by technology

It takes a long time to cultivate older seedlings, which consumes a lot of human resources and time, and the cost is high

[0005] (2) The root system of seedlings is not well developed, the quality of seedlings is poor, and the survival rate after afforestation is extremely low

The natural climatic conditions of the afforestation land are relatively harsh, the roots of the seedlings are poorly developed, they cannot be deeply rooted, and the water absorption and nutrient efficiency are low, resulting in poor quality of the seedlings, poor adaptability after transplanting and afforestation, and low survival rate

[0006] (3) Afforestation construction process is difficult

First of all, difficult afforestation land has complex terrain, high and steep mountains, and large seedlings are bulky and heavy. Generally, transportation equipment is needed to transport them to afforestation land, which greatly increases the difficulty of afforestation work.

Secondly, the soil layer of the afforestation land is thin, the rocks are many and hard, and it is difficult and laborious to dig holes.
