Embodiment 1

[0033] A method for afforestation of black pine bare-root saplings based on negative pressure technology and liquid immersion, comprising the following steps:

[0034] 1. Land preparation:

[0035] Use horizontal ditches for site preparation, and dig ditches from top to bottom along the hillside contour line. The distance between the top and bottom is 1.5-1.8m, and the left and right is 0.3-0.4m;

[0036] 2. Transplanting and later management and maintenance:

[0037] Before transplanting, the black pine bare root saplings are first placed in the container of the nutrient solution, and the container is placed in the negative pressure tank, and the pressure value of the negative pressure tank is adjusted by the pressure pump to -90KPa, soaked for 3min, The roots of the treated black pine bare-rooted saplings are covered with wet cloth; when transplanting, put the black pine bare-rooted saplings in the planting pit, arrange the root system, make the roots stretch evenly, fill ...

Abstract

The invention provides a black pine bare-root sapling afforestation method based on negative pressure technology and liquid immersion, comprising the following steps: 1. Site preparation; 2. Transplanting and subsequent management and protection; before transplanting, negative pressure technology and nutrient solution soak In combination, soak the black pine bare-root saplings; when transplanting, cover the roots of the black pine bare-root saplings with film materials; also cover the surface of the planting pit with film materials; three, pest control: pest control includes black pine branch blight, pine Large aphid pests; prevention and control of black pine branch blight: remove diseased dead branches, fallen leaves and weeds in time, loosen the soil, weed, and fertilize in time; spray 70% thiophanate-methyl 400 times solution in April and August, and spray in January Once; the prevention and control of pine aphids: Spray 1200 times of liquid consisting of cyclopyrid, imidacloprid and deltamethrin EC to the roots of black pine. The invention effectively improves the stress resistance and survival rate of the saplings through the treatment of the bare-rooted saplings before transplanting, the film-covering treatment during the transplanting, and the prevention and control of diseases and insect pests in the later stage, and the cost is low.

Description

technical field [0001] The invention relates to the field of afforestation on barren hills, in particular to a method for afforestation of black pine bare root saplings based on negative pressure technology and liquid immersion. Background technique [0002] The ecological environment is the basic condition for human survival and development, and the basis for economic and social development. Protecting and improving the ecological environment and realizing sustainable development is a basic policy that must be adhered to in our country's modernization drive. But at present, my country's ecological environment is still relatively fragile, and the area of ​​barren hills caused by soil erosion has not been effectively curbed. Therefore, it is imminent to carry out afforestation on barren hills to improve the ecological environment. Compared with ordinary afforestation, afforestation on barren hills will face more difficulties, mainly due to problems such as long-term barren ...
