Problems solved by technology

The soil in this area is mostly sand and gravel, with a small heat capacity. The surface and underground temperature fluctuates greatly with the seasons, day and night temperature and light intensity. The phenomenon of water leakage and running fertilizer is serious, which is not conducive to the growth of trees.

Embodiment 1

[0025] Embodiment 1, apply the inventive method to plant Qinghai spruce

[0026] Experimental location: Naqu Town, Tibet Autonomous Region. Trees: 10-year-old Qinghai spruce (48 trees).

[0027] One, adopt the method of the present invention to plant trees

[0028] 1. Production of thermal insulation and moisturizing protective partitions

[0029] The general construction market buys plastic foam boards with a length of 2 meters, a width of 1 meter, and a thickness of 5 cm, and cuts them into widths of 50 cm; cuts the special plastic film for plastic greenhouses, folds the cut film in half, and overlaps the seams by 2 to 3 cm. Seal it into a cylinder with a sealing machine or an iron; insert the plastic foam board into it, and seal both ends (you can also wrap the foam board tightly with a cut film and seal it with plastic tape), heat preservation and moisture protection partition manufacture complete.

Abstract

The invention discloses a method for protecting a plateau forest tree seedling planting root. The method provided by the invention is characterized by comprising the following steps of: (1) mounting a partition plate around the wall by a circle on the wall of a planting groove or a planting cavity; superposing the lower edge of the partition plate with the bottom surface of the planting groove or the planting cavity; leading the upper edge of the partition plate to be lower than the upper edge of the planting groove or the planting cavity, wherein the partition plate is obtained by sealing the surface of a foam plant with a plastic film or a thermoplastic film; and (2) planting the forest trees in the planting groove or the planting cavity; and after filling soil, covering a surface layer by an earth surface covering material. The method of invention can improve the soil microenvironment in the forest tree planting groove or cavity in a high-altitude and high-cold area and the planting survival rate of forest trees, promote forest tree growth and provide a special facility technology for forest tree planting in plateau ecological construction.

Description

technical field [0001] The invention relates to a root system protection method for planting forest tree seedlings in plateaus, in particular to a method for improving the temperature of the soil matrix in open field planting tanks (or planting holes) for forest tree seedlings in high-altitude alpine regions. Background technique [0002] The annual average temperature in high-altitude alpine regions in my country is close to or lower than 0°C. The annual average temperature in Nagqu Town on the northern Tibetan plateau is -1.5°C; ground temperature monitoring shows that the average temperature at a depth of 40 cm underground is 1.6°C in spring, 10.9°C in summer, 6.2°C in autumn, and -3.7°C in winter; the underground temperature decreases with increasing depth from May to October The trend is that the underground temperature increases with the depth from November to April of the following year; that is, the heat is transported from the ground to the top in autumn and winter,...
