Problems solved by technology

The phenomenon of "summer dormancy" exhibited by Haloxylon Haloxylon (or Haloxylon white) can make Haloxylon Haloxylon (or Haloxylon Haloxylon) safely through the severe adversity period in summer, but on the other hand it makes Haloxylon Haloxylon (or Haloxylon Haloxylon) Haloxylon) shortens the effective growth period and significantly reduces the annual growth, which is extremely unfavorable to the restoration and construction of Haloxylon (or Haloxylon white) forest

Embodiment

[0024] Ecological protection measures prevent natural and artificial Haloxylon (or white Haloxylon) forest from taking place "summer dormancy" (adversity physiological retardation) phenomenon as follows:

[0025] (1) Implementation location: Beishawo, Fukang, Xinjiang;

[0026] (2) Implementation scope: 500 Haloxylons over 2 years old;

[0027] (3) Implementation time: March 25, 2009;

[0028] (4) Implementation method: when the companion plants were sown, it was the early spring in northern Xinjiang, and there was still snow on the surface. Sow the seeds of the annual companion plants such as thorn thorn, podgrass, spinach, wormwood, thorn grass, foxtail, flygrass, three Miscanthus, bluegrass, small deer hair, etc. directly on the rhizomes of Haloxylon under the Haloxylon forest On the snow within 50cm, use your feet to properly press the seeds to prevent them from being blown away by the wind. Sow more than 200 grains per square meter, and try to increase the sowing amoun...

Abstract

The invention relates to an ecological protection method for preventing the summer donnancy of halaxylon ammodendron forest, which belongs to the field of forestry ecological cultivation science. Because of the forest land condition, the summer donnancy of halaxylon ammodendron (or haloxylon persicum) occurs for many years, but the underground water supply of the shallow forest ground layer is rich. Various plants and seeds thereof applicable to desert or semidesert environment growth and commonly in concomitance with the halaxylon ammodendron (or haloxylon persicum) are adopted for sowing in a circle with the radius about 50 cm around the base part of the root and stalk of the halaxylon ammodendron (or haloxylon persicum), and more than 200 seeds are sowed per square meter. Through the invention, the halaxylon ammodendron (or haloxylon persicum) can still grow normally under the extreme adverse environment conditions in summer, and the physiological phenomenon of summer donnancy does not occur, so the fast growth of the individual plants of the halaxylon ammodendron (or haloxylon persicum) is promoted, and the annual growth quantity is increased. The invention has the advantages of strong operability, good repeatability, high efficiency and simple method, and has the significant meaning for the ecological restoration reconstruction of the desert or semidesert large-scale halaxylon ammodendron (or haloxylon persicum) forest in China.

Description

1. Technical field [0001] The invention relates to an ecological protection method for preventing "summer dormancy" in Haloxylon forest, a method for preventing it from entering the "summer dormancy" state in summer, belonging to the field of forestry ecological cultivation, and is specially used to prevent Haloxylon (or Haloxylon white) In the summer of extreme adversity, the physiological phenomenon of "summer dormancy" occurs, which promotes the growth of Haloxylon (or Haloxylon) and increases the 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 two kinds of Haloxylon ammodendorn (C.A.Me.) Bunge, also known as Haloxylon persicum Bunge ex Boiss et Bushse, in China. Haloxylon is a super-xerophytic small tree. It is a tall sh...
