Problems solved by technology

At present, the vegetation under normal conditions is not suitable for large-scale planting of desertified land under abnormal conditions. Due to the poor weather conditions and insufficient water supply, the survival rate is low, and the conditions for improving and utilizing desertified land cannot be realized in a short time.

Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] like figure 1 As shown, the present invention provides a desertification land vegetation restoration method, comprising the following steps:

[0023] Step 1: Dig out neat circular pits 1 with a diameter of 30 cm and a depth of 20 cm on the sandy land to be treated. Each round pit 1 is regarded as a planting unit (a square area of ​​90cm*90cm). During precipitation, the rainwater washes the ground and stays in these dense circular pits 1. Because of the shape of the circular pits 1, the water is firmly locked and will not be easily lost.

[0024] Step 2: Fill the circular pit 1 with mixed matrix sand with a thickness of 10-12 cm, including sand, wood chips, organic fertilize...

Abstract

The invention discloses a method for restoring vegetation in sandy land, which comprises the following steps: step a, dig out round pits arranged horizontally and vertically on the sandy land to be treated, and four adjacent round pits are used as a planting unit; step b, in the The round pit is covered with mixed matrix sand; step c, making a plant seed protection bag; step d, burying most of the plant seed protection bag in the above-mentioned round pit mixed matrix sand, and then laying a layer of local sand on the surface of the above-mentioned round pit, and the above-mentioned The upper end of the protective bag can be flush; step e, every four planting units form a grid to form a grid, and build a sandbag retaining wall outside the grid; step f, open a cross groove in the grid, and fill the groove The above-mentioned mixed substrate sandy soil is then evenly spread and sprinkled xerophyte herbaceous plant seeds in the trench, and finally a layer of local sandy soil is laid on the surface of the trench. The desertified land vegetation recovery method of the present invention can cope with the harsh conditions of the desertified land, achieve a good water storage effect, and improve the vegetation survival rate.

Description

technical field [0001] The invention specifically relates to a method for restoring vegetation on desertified land, and belongs to the technical field of methods for restoring desertified land environment. Background technique [0002] Sandified land refers to the degraded land formed by various factors under various climatic conditions, and the surface is mainly marked by sand, including the land that has been desertified and the land with obvious desertification trend. At present, vegetation under normal conditions is not suitable for large-scale planting of desertified land under abnormal conditions. Due to poor climatic conditions and insufficient water supply, the survival rate is low, and conditions for improving and utilizing desertified land cannot be achieved in a short time. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for restoring sandy land vegetation which can cope with the harsh conditions of sandy land, achie...
