Method for controlling wind erosion of nursery stock bases in desert areas

Abstract

The invention relates to a method for controlling wind erosion of nursery stock bases in desert areas. The method relates to a nursery stock sand storm protection cover which comprises a cover body, a cover edge and a fixed drill rod, wherein the cover body is shaped like a round table; the cover edge is arranged at the bottom of the cover body; and the fixed drill rod is inserted into a fixed hole on the cover edge and then fixed in soil on the earth surface. After a nursery stock is planted in a desert area, the nursery stock sand storm protection cover is taken, and the cover body and a gap on the side wall of the cover edge are slightly unfolded to horizontally move toward the nursery stock; branches of the nursery stock are collapsed and pass through the gap; the cover body is arranged around the nursery stock; the protection cover is rotated to ensure that the gap on the protection cover is toward the downwind direction of the local predominant wind direction; and along with the growth of the nursery stock, when the sand storm protection cover limits the growth of the trunk, the cover body and the gap on the side wall of the cover edge are unfolded and then the protection cover is taken off. The method can be used for the forestation in desert areas with the advantages of improving the micro environment of nursery stock bases, preventing the wind erosion of the soil at the roots of the newly planted seedlings and improving the nursery stock survival rate, has a wide application range and can be widely applied to the construction projects of ecological forests and economic forests.

Description

technical field [0001] The invention relates to an afforestation method, in particular to a method for controlling wind erosion of seedling roots in sandy areas. Background technique [0002] Plants are very fragile in the seedling stage, and meteorological disasters such as high and low temperature, strong wind, and atmospheric drought, as well as the gnawing and gnawing of rats, rabbits, and large herbivores, can be fatal. For seedlings in windy and sandy areas, in addition to the above disasters, windy sand is the limiting factor affecting their survival and growth. The wind loosens the roots of the seedlings and affects the growth of new roots; the impact of sand particles abrades the new leaves and plant epidermis; wind erosion strips the root soil and even exposes the root system, which affects the water absorption of the plant. Therefore, certain protective measures must be taken for seedlings in areas with strong wind and sand activity, in order to improve the survi...

Problems solved by technology

However, these protective covers are all columnar with the same thickness up and down, and cannot fit each other, occupy a large space, and are not convenient for transportation; the side walls are all designed to be airtight, and wind resistance can easily cause soil wind erosion; the side walls are all closed , it is not easy to install and disassemble; in addition, the materials used are mostly high molecular polymers, which are difficult to degrade naturally and can cause environmental pollution

At present, a new type of seedling protection cover (201010523477.X) has also appeared. It is time-consuming and labor-intensive to assemble and arrange the support frame and shade net on site, and the cost is also high
