Embodiment 1

[0019] like figure 1 Shown, a kind of dead body and living body two-row sand barrier grid sand fixation control method, at first, fix double-row sand barrier grid, described double-row sand barrier grid comprises main zone sand barrier and secondary belt sand barrier, and the main The belt sand barrier and the secondary belt sand barrier are arranged in a grid, and the main belt sand barrier includes living sand barrier yellow willow on both sides and dead body sand barrier dry branches arranged between the living sand barrier yellow willow on both sides. Said sub-band sand barrier comprises living sand barrier caragana on both sides and dead body sand barrier dry branches arranged between said living sand barrier caragana on both sides; In each grid formed by the main belt sand barrier and the secondary belt sand barrier, sandy land suitable tree species are planted.

[0020] figure 1 Among them, the main sand barrier is set horizontally, and the secondary sand barrier is s...

Embodiment 2

[0029] In this embodiment 2, on the one hand, the selected arbor species is Pinus tabulaeformis, the seedling age is more than 6 years and the seedling height is more than 70cm, and 111 plants are planted per mu; The height is more than 50cm, and 220-330 plants are planted per mu.

[0030] Under the same site conditions, the same tree species, and the same tree age, three different sand-fixing techniques were used to investigate and compare the vegetation coverage, seedling preservation rate, plant height, and crown width within three years. As shown in Table 1 and Table 2, it can be seen that the vegetation coverage, seedling preservation rate, plant height, and crown width three years after planting are all higher than those of the other two technologies, and the ecological benefits are very significant. .

Abstract

The invention discloses a method for sand fixation of a dead body and a living body double-row sand barrier grid. Firstly, the double-row sand barrier grid is fixed. The main belt sand barrier and the secondary belt sand barrier are arranged in a grid, and the main belt sand barrier includes living sand barrier yellow willow on both sides and dead body sand barrier dry branches arranged between the living sand barrier yellow willow on both sides, Described sub-band sand barrier comprises living sand barrier caragana on both sides and the dead body sand barrier dry branch arranged between the living sand barrier caragana on both sides; After the double row sand barrier grid is fixed, the second In each grid formed by the sand barrier in the main zone and the sand barrier in the secondary zone, plant suitable tree species in the sandy land every year. The present invention performs double-layer sand fixation through the double-row grid pattern of the living sand barrier and the dead sand barrier. The double-row sand barrier can block the wind and sand in the early stage, and the dead sand barrier decays into organic matter in the later stage, providing nutrients and water for the living sand barrier, and effectively improving the living body. sand-blocking ability.

Description

technical field [0001] The invention relates to the technical field of sand control and control, in particular to a sand-fixing control method for double-row sand barrier grids of dead bodies and living bodies. Background technique [0002] my country is one of the countries where the phenomenon of desertification is very serious, and desertification has caused a very serious impact on my country's economic development and social progress. One of the important factors causing desertification is the flow of sand dunes, which has encroached on a large number of fertile fields. Therefore, sand body fixation is the most important content in the construction of sand prevention and control projects. Although the sand-fixing control methods used in the current sand control and control projects have certain effects, due to soil erosion and spring wind and sand erosion, the desertified and eroded area is gradually increasing, making it impossible to fundamentally curb the deteriorati...
