Problems solved by technology

[0005] Technical Problem The object of the present invention is to provide a method for significantly improving the survival rate of direct seedlings, natural seedlings and transplanted seedlings of Haloxylon plants in desert and semi-desert areas To solve the key problems such as the low survival rate of seedlings caused by frequent extreme surface high temperatures and the slow growth of individuals caused by the frequent occurrence of "summer dormancy" in the process of large-scale restoration and construction of Haloxylon plant forests

Embodiment

[0029] The methods for improving the survival rate of live seedlings, natural seedlings and transplanted seedlings of Haloxylon plants by using protective nets in desert and semi-desert environments are as follows:

[0030] (1) Implementation location: desert stockyard in Kalamaili Mountain Nature Reserve, Jungar Basin, Xinjiang, which is the most extreme and harsh desert habitat;

[0031] (2) Implementation scale: 200 direct seedlings of Haloxylon, 200 natural seedlings and 200 transplanted Haloxylon seedlings over 2 years old;

[0032] (3) Implementation time: March 25, 2009;

[0033] (4) The structure, type and specification of the protective net cover: the protective net cover is mainly composed of a sunshade net surface, a skeleton and anchor claws, and is in the shape of a cone with a small upper part and a larger lower part. : 2-3 is appropriate. The frame and anchor claws of the net cover are made of 8~10# thick iron wire (the anchor claws can also be made of 5~8...

Abstract

The invention relates to a method for improving the survival rate of haloxylon seedlings, which belongs to the field of forestry ecological plant, is specifically used for protecting haloxylon seedlings by using a protective net cover in a process of massively restoring and building a haloxylon forest in a desert or semi-desert region, obviously improves the survival rate of the haloxylon seedlings and prevents the phenomenon of 'summer dormancy' of the haloxylon seedlings. The protective net cover is divided into two types, namely a directly sown seedling or naturally growing seedling protective net cover and a transplanted seedling protective net cover. By the method, the haloxylon seedlings can be effectively prevented from being harmed or threatened by the supracrustal high temperature, blown sand, animals and the like, supracrustal water evaporation can be locally reduced and vegetation coverage can be increased, so that the survival rate of the haloxylon seedlings is improved byover 30 percent. The operability is strong; the efficiency is high; and the method is simple and has very important significance for massively restoring and building the haloxylon forests in desert or semi-desert regions in drought regions of China, even African-Asian mainland.

Description

technical field [0001] The invention mainly relates to a method for improving the survival rate of Haloxylon plant seedlings, which belongs to the field of forestry ecology and cultivation, and is specially used in the implementation process of large-scale restoration and construction of Haloxylon genus plant forests in desert and semi-desert areas. Survival rate of Haloxylon plant seedlings and prevention of "summer dormancy" phenomenon. Background technique [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, growing on mobile sand dunes, semi-fixed sand dunes, saline soil and gravel Gobi. Haloxylon in China ( Haloxylon ammodendorn (C.A.Me.) Bunge, also known as Haloxylon or Black Haloxylon) and White Haloxylon ( Haloxylon persicum Bunge ex Boiss et Bushse) two. The distribution area of ​​Haloxylon in my country is about 1139.3×10 4 hm 2 , accounting for 9% o...
