Wind prevention and sand fixation greening planting technology

Abstract

The invention discloses a wind prevention and sand fixation greening planting technology with good sand control effect. The wind prevention and sand fixation greening planting technology mainly comprises the following steps of: firstly arranging a plurality of strip sand-protecting barriers in a traveling dune zone; then mix-seeding herbaceous plant seeds in open grounds among the strip sand-protecting barriers, and planting shrub seedlings at the positions where the strip sand-protecting barriers are located; and finally fertilizing among the strip sand-protecting barriers and inside the strip sand-protecting barriers. According to the wind prevention and sand fixation greening planting technology, normal germination growth of most herbaceous plant seeds and shrub seedlings can be ensured without planting by multiple times; moreover, the growth period of herbaceous plants is relatively short, so that grass capable of sand fixation can be formed in a short time to further ensure normal growth of shrub seedlings; a grass and shrub forest can be formed in a relatively short time, two to three years in general, through the combination of the sand fixation of sand-protecting barriers with grass and shrub plants so as to achieve the effects of wind prevention and sand fixation; and the desertification of land can be effectively prevented. The technology is suitable for popularization and application in the technical field of sand control.

Description

technical field [0001] The invention relates to the technical field of sand control, in particular to a windproof and sand-fixing greening and planting technology. Background technique [0002] my country is one of the countries most seriously affected by desertification in the world. There are more than 2 million square kilometers of desertified land, accounting for nearly one-third of the total land area, and a large amount of land is desertified every year. Therefore, how to effectively prevent the land from being desertified has always been an urgent problem to be solved. [0003] At present, how to prevent the land from being desertified is generally adopted to build shelter forests, that is, to plant shrubs and trees in the mobile sand dune area. However, the existing way of building a shelterbelt takes a long time to form a shelterbelt. The main reasons are: the first is that the shrubs and trees in the seedling stage have low plants and large gaps between plants, so ...

Problems solved by technology

[0003] At present, how to prevent the land from being desertified is generally adopted to build shelter forests, that is, to plant shrubs and trees in the mobile sand dune area. However, the existing way of building a shelterbelt takes a long time to form a shelterbelt. The main reasons are: the first is that the shrubs and trees in the seedling stage have low plants and large gaps between plants, so it is difficult to form a shelterbelt in a short time to fix the quicksand on the surface to stop the flow of quicksand; The sandy soil in the mobile sand dune area is always in a state of flow, and it is easy to blow down or bury the planted shrubs and tree seedlings, resulting in a low survival rate of the shrubs and trees. It takes multiple plantings to form a shelter forest. Sand-fixing shelterbelts usually take more than ten years. Therefore, the existing windbreak and sand-fixing greening and planting technology takes a long time to form a shelterbelt, which cannot effectively prevent land from being desertified, and the effect of sand control is poor.
