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.
