Abstract

The invention relates to a physical protection method for preventing summer dormancy of haloxylon ammodendron forest, belonging to the field of ecological cultivation of forestry. Years haloxylon ammodendron or haloxylon persicum forest land has abundant shallow ground water supply; and general material, such as straw screens, straws, wheat straws or straw ropes and the like and organic heat insulation materials, such as polystyrene board and the like are chosen. The materials are applied all over the year and are maintained once before summer dormancy to ensure that the base of the root and the stem of the haloxylon ammodendron or haloxylon persicum are effectively separated from shallow ground matrix. The method can ensure that the haloxylon ammodendron (or haloxylon persicum) can normally grow under the extreme adverse circumstance in summer, generates no 'summer dormancy' physiological phenomenon and quickens the growth of artificial haloxylon ammodendron (or haloxylon persicum). The invention has strong maneuverability, favorable repeatability, high efficiency and simple method and has an important meaning for large-scale ecological restoration and reconstruction of haloxylon ammodendron (or haloxylon persicum) forest in desert and semi-desert in China.

Description

1. Technical field

[0001] The invention relates to a physical protection method for preventing summer dormancy in Haloxylon forest, which belongs to the field of forestry ecological cultivation, and is specially used to prevent the physiological phenomenon of "summer dormancy" in Haloxylon (or H. Shuttle (or Haloxylon white) growth, the method of increasing annual growth. 2. Background technology

[0002] There are 11 species of Haloxylon genus Chenopodiaceae in the world, mainly distributed in the vast desert areas from the Mediterranean to Central Asia, where they grow in mobile sand dunes, semi-fixed sand dunes, saline soil and gravel Gobi. There are Haloxylonammodendorn (C.A.Me.) Bunge in China, also known as Haloxylon persicum Bunge ex Boiss et Bushse. Haloxylon is a super-xerophytic small tree. It is a tall shrub. The plant height is generally 2-3m, and individual plants can be as high as 10m. It has a very large root system. The vertical roots can reach more than 9m,...
