Embodiment Construction

[0009] figure 1 It intuitively and truly reflects the characteristics of the grid design of the plant living sand barrier in this sand-fixing method. The technical key of the present invention is to select suitable annual sand barrier protection plant species and their mixing ratio with target tree species, sand barrier grid design and rainy season sowing time. According to the characteristics of the sandy land and the ups and downs, determine the size of the grid or strip size of the live plant live sand barrier; according to the principle of water balance and the succession law of local vegetation, the afforestation tree species, nursery stock specifications, Afforestation density, afforestation time, etc.; scientific management and management techniques to ensure that the live-sand plant live sand barrier permanently exerts its sand-fixing effect. Select plant materials such as Yangchai and wheat, and according to the differences in the growth characteristics and life cycl...

Abstract

The invention discloses a sand fixing method for a direct-seeding plant living sand barrier especially for sand comprehensive treatment. In the method, a target species hedysarum fruticosum and associated sand barrier plant wheat are mixed in proportion, and performing biological sand barrier mechanical direct-seeding operation according to designed grid in June rainy season, wherein furrowing soil preparation, planting and earthing are completed in one time. The method directly seeds therophyte which can form a dense green sand barrier in the same year by sufficiently playing the fast growing advantage of the therophyte to protect the target plant (hedysarum fruticosum) seedling from winter in growth period and wind erosion next year, so that the target plant can grow normally in the next year, a grid-shaped biological sand barrier can be formed naturally to permanently play the sand stabilizing effect of the plant living sand barrier.

Description

technical field [0001] The invention relates to a sand-fixing method for comprehensive management of sandy land, in particular to a sand-fixing method for direct-seeding plant live sand barriers. Background technique [0002] How to fix mobile sand dunes is the most important content in the construction of sand prevention and control projects. On the one hand, the mobile sand dunes are highly mobile and harmful, so they must be effectively governed and controlled; on the other hand, the water in the mobile sand dunes is relatively good, but the wind erosion is serious, so it is easy to establish artificial vegetation to survive, but difficult to preserve. Therefore, taking effective technical measures to control wind erosion of mobile sandy land is the key link to establish vegetation and control mobile sand dunes. [0003] Setting up sand barriers is a commonly used and effective technical measure in the construction of sand prevention and control projects, especially in t...
