Film coat drought defying and tillage afforestation method for Pinus Sylvestris var sands

Abstract

The invention discloses a sand afforestation technology comprising planting the nursery stock, spreading the plastic foil onto the backfill soil surface. The advantages of the invention are, the moisture evaporation around the sapling rhizome can be reduced, and the skin layer soil moisture can be improved.

Description

technical field [0001] The invention relates to sandy land afforestation technology, in particular to a method for afforestation of Pinus sylvestris pine sandy land covered with film to resist drought. Background technique [0002] Pinus sylvestris mongolica Litv, as a geographical variety of Pinus sylvestris L., is naturally distributed in the Hulunbeier area of ​​the Greater Khingan Mountains. It belongs to the zonal forest vegetation of the Greater Khingan Mountains. It is one of the important afforestation tree species in Northeast my country and Inner Mongolia. Pinus sylvestris has excellent characteristics such as strong cold resistance, drought resistance, wind and sand resistance, and barrenness resistance. It is the main tree species for building wind-proof and sand-fixing forests, farmland, pasture protection forests, water and soil conservation forests, and timber forests in the semi-arid and sandy areas of northern my country; In arid and semi-arid desertified area...

[0002] Pinus sylvestris mongolica Litv, as a geographical variety of Pinus sylvestris L., is naturally distributed in the Hulunbeier area of ​​the Greater Khingan Mountains. It belongs to the zonal forest vegetation of the Greater Khingan Mountains. It is one of the important afforestation tree species in Northeast my country and Inner Mongolia. Pinus sylvestris has excellent characteristics such as strong cold resistance, drought resistance, wind and sand resistance, and barrenness resistance. It is the main tree species for building wind-proof and sand-fixing forests, farmland, pasture protection forests, water and soil conservation forests, and timber forests in the semi-arid and sandy areas of northern my country; In arid and semi-arid desertified areas, due to the influence of various harsh environmental factors such as arid climate, more wind and less rain, and wind erosion and desertification, the survival rate and preservation rate of Pinus sylvestris sylvestris are low after afforestation, resulting in the current sandy land vegetation restoration process. The situation is dominated by shrubs and broad-leaved trees (mainly poplars) with few coniferous species

In the past, the traditional method of afforestation of Pinus sylvestris was to plant bare-rooted biennial seedlings of Pinus sylvestris in spring. During the peak period of wind and sand, the water in the seedlings and soil will decrease sharply in a short period of time, and the seedlings will wither and die due to excessive water loss. Can not produce good results in the environment, the survival rate of afforestation is low
