Embodiment 1

[0037] A method for afforestation of black pine bare-root saplings based on negative pressure technology and liquid immersion, comprising the following steps:

[0038] 1. Land preparation:

[0039] 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;

[0040] 2. Transplanting and later management and maintenance:

[0041] 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 lodgepole pine bare-root sapling forestation method based on a negative pressure technology and liquid soaking. The lodgepole pine bare-root sapling forestation method based on the negative pressure technology and the liquid soaking comprises the following steps of (1) soil preparation; (2) transplantation and final management and maintenance: before transplanting, soakinglodgepole pine bare-root saplings by adopting the combination of the negative pressure technology and the nutrient solution soaking; during transplanting, covering roots of the lodgepole pine bare-root saplings with thin film materials; and covering the surfaces of planting pits with the thin film materials; (3) pest control: preventing and controlling lodgepole pine branch rot and cinara pintabularformis zhang et zhang, wherein the lodgepole pine branch rot is prevented and controlled through the following steps of timely clearing diseased deadwood, fallen leaves and weeds, timely looseningthe soil, weeding, and fertilizing, spraying 400 times of liquid of 70 percent thiophanate methyl once a month in April and August; and the cinara pintabularformis zhang et zhang is prevented and controlled through the following step of spraying 1200 times of liquid prepared from cycloxaprid, imidacloprid and deltamethrin missible oil on the roots of a lodgepole pine. According to the lodgepole pine bare-root sapling forestation method based on the negative pressure technology and the liquid soaking provided by the invention, through the treatment on the bare-root saplings before transplanting, the film covering treatment during transplanting, and the later-period pest control, the stress resistance and the survival rate of the saplings are effectively improved, and the cost is low.

Description

[0001] Technical field: [0002] 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. [0003] Background technique: [0004] 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 ...
