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.
