Planting method for increasing bare-rooted seedling afforestation survival rate with water-saving irrigation

Abstract

The invention discloses a planting method for increasing the bare-rooted seedling afforestation survival rate with water-saving irrigation. The planting method comprises the following steps: I, selecting tree species: selecting any one of the trees species pinus thunbergii, platycladus orientalis, elm, robinia pseudoacacia, cotinus coggygria and fraxinus chinensis; II, digging a planting hole: confirming the shape and the specification of the planting hole according to the type of the afforestation land and the specification of a seedling, wherein the planting hole generally takes the shape of a circular truncated cone in a plain area, the specification of the planting hole can be slightly large in a non-salt and alkali area, the diameter of the upper part of the planting hole is 60-80 cm, the diameter of the lower part of the planting hole is 40-60 cm, and the depth of the planting hole is 60-80 cm, and in a plain salt and alkali area, the diameter of the upper part of the planting hole is 50-60 cm, the diameter of the lower part of the planting hole is 40-50 cm, and the depth of the planting hole is 50-60 cm. By adoption of the planting method, limited moisture can be concentrated around the root system of the seedling and is not easy to evaporate or diffuse, water supply to the root system of the seedling in the key survival period can be assisted, sucking of weeds to moisture and nutrient in soil can be reduced, an ideal small environment is provided for survival and growth of seedling root systems, the afforestation survival rate can be ensured, and the problems that the afforestation irrigation cost is high and the afforestation survival rate is low in a water-deficient area are solved.

Description

technical field [0001] The invention relates to a water-saving irrigation afforestation technology, in particular to a planting technology for improving the survival rate of bare-root seedling afforestation in water-deficient areas. Background technique [0002] my country is a water-scarce country, especially in the northern arid areas where the water shortage is more serious. Moisture is a necessary condition for the survival of seedlings. Water shortage will easily lead to a low survival rate of afforestation, especially the lower survival rate of bare-root seedling afforestation. Water shortage The main difficulties in afforestation of bare-root seedlings in the area are: first, the lack of water resources, which cannot provide enough water for seedlings to survive; second, the large amount of soil evaporation causes soil drought, and it is easy to compete with seedlings for water; It is not easy to get sufficient and timely supplement of water, which may easily cause the ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to provide a water-saving and drought-resistant afforestation method that is simple, saves irrigation costs, and improves the survival rate of bare-root seedling afforestation in water-deficient areas. The method can concentrate limited water resources around the roots of seedlings, and is not easy to evaporate and lose. Help solve the root water supply during the critical period of seedling survival, reduce the competition of weeds for soil moisture and nutrients, provide an ideal microenvironment for the survival and growth of seedling roots, ensure the survival rate of afforestation, and solve the high cost of afforestation irrigation in water-deficient areas , The problem of low survival rate of afforestation
