Method for fast building biology movable sand-protecting barrier

Abstract

The invention discloses a method for fast building a biology movable sand-protecting barrier. According to the method, firstly, a matrix is prepared and mixed with seeds of shrub and herbaceous plants; secondly, the prepared matrix is wrapped into a plant growing bar through the cigarette rolling technology; thirdly, the plant growing bar is buried under the sand in a latticed or line ribbon mode during the rainy season, and the biology sand-protecting barrier is formed after sprouts grow. The method is easy to implement, the plant growing bar is easy to arrange, manpower and material resources are saved, the biology movable sand-protecting barrier can stably play a role in ecological and economic benefits for a long time, and ecological restoration and construction are accelerated.

Description

Technical field [0001] The invention relates to a wind-proof and sand-fixing technology, in particular to a method for rapid construction of biological living sand barriers. Background technique [0002] In the prevention and control of desertification, mechanical sand barrier is an important sand fixation measure. For many years, it has played a very significant role in our national defense sand control practice. There are many types of sand barriers, which can be divided into mechanical sand barriers and biological sand barriers. The mechanical sand barrier has a variety of materials, including crop stalks, tree branches, clay, pebbles, plastic nets, nylon bags, etc. The layout method can be divided into square format or belt type according to the prevention and control requirements, and the specifications of the sand barrier can be based on the protection area. The activity intensity and material characteristics are determined. Usually, the layout specification of the wheatgr...

Problems solved by technology

[0003] In the prior art, the layout method of biological live sand barriers is mostly the planting of shrub plants in rows. The planted tree species generally include sand-growing shrubs such as Dongjiang Azalea, Haloxylon, Salix, etc., which are mainly planted by cuttings and planting seedlings. The method requires digging trenches for planting, and adopts drip irrigation or other irrigation measures in areas with low water content in sand dunes, which requires a lot of manpower, high cost, slow growth of plants, low survival rate, and replanting is required when necessary. The forest belts cannot quickly form the effect of windbreak and sand fixation
