Severe soda saline-alkaline land elaeagns angustifolia afforestation keep-alive method

Abstract

The invention discloses a severe soda saline-alkaline land elaeagns angustifolia afforestation keep-alive method, and aims to provide new tree species and new methods for severe soda saline-alkaline land elaeagns angustifolia afforestation keep-alive in the northeast western area. The method comprises the steps of: planting with nutrient soil, timely nurturing and arranging necessary auxiliary engineering facilities, wherein the step of planting with nutrient soil comprises the following sub-steps of: 1, selecting the planting time; 2, selecting elaeagns angustifolia seedlings and cutting trunks; 3, determining the planting density; 4, preparing the nutrient soil; 5, digging seedling planting holes; and 6, adopting a method of burying for three times, stamping twice and lifting the seedlings once, timely watering and sealing piles in proper time; the step of timely nurturing comprises the sub-steps of loosening the soil and weeding twice in the first year, and cutting stubbles in the second year; and the step of arranging the necessary auxiliary engineering facilities comprises the sub-step of forming a deep-water motor-pumped well, protection trenches with the width of 4m and the depth of 2m and dual-purpose ditches for drainage and storage, wherein the step of forming the dual-purpose ditches comprises the step of forming dual-purpose ditches with the width of 0.6m and the depth of 0.8m at an interval of 30 to 50m in an afforestation plot.

Description

technical field [0001] The invention relates to a method for afforestation and keeping alive, which belongs to the technical field of forestry planting, and more specifically, the invention relates to a method for afforestation and keeping alive of Elsewhere in severe soda saline-alkali soil. Background technique [0002] There are large areas of saline-alkali land in the world, covering more than 80 countries and regions. my country's Songnen Plain is one of the world's three concentrated distribution areas of soda saline-alkali land. [0003] The ecological environment in this area is relatively poor, the ecosystem is relatively fragile, the land salinization area accounts for 30.6% of the total land area, the vegetation types are relatively single, and there are few tree species suitable for planting. Taking Da'an City, Jilin Province as an example, 50.8% of the land suffers from different degrees of salinization hazards, of which 40.7% are severely saline-alkali land, s...
