Arbor-shrub-grass planting method for arid region underground-water-shallow-buried saline-alkali soil

Abstract

The invention relates to an arbor-shrub-grass planting method for arid region underground-water-shallow-buried saline-alkali soil and belongs to the technical field of saline-alkali soil vegetation construction. The planting method includes the steps of A, ridging the original saline-alkali soil, flattening ridge surfaces, and processing soil hardening; B, forming a planting structure which includes a grass plant row, a shrub row, a grass plant row, an arbor row, a grass plant row, a grass plant row, a shrub row and a grass plant row on the ridge surfaces in a three-dimensional coordinated manner; C, performing water and salt regulation after the planting structure is formed; D, respectively performing spring irrigation and winter irrigation when the growth period of each year starts and ends, and performing pruning, protection and disease and pest control on the plants. The planting method has the advantages that vegetation coverage is increased, and the problem that the arid region underground-water-shallow-buried saline-alkali soil is high in salinity degree, high in underground water level, easy in accumulation of salt in the surface soil and ecologically fragile is solved.

Description

technical field [0001] The invention belongs to the technical field of vegetation construction on saline-alkali land, and in particular relates to a method for planting trees, shrubs, and grasses by drip irrigation in shallow groundwater buried in severe saline-alkali land in arid areas. Background technique [0002] In the arid inland areas of Northwest my country, saline-alkali land is widely distributed in areas with low terrain, poor drainage or sluggish surface runoff. The groundwater in these saline-alkali lands is shallow, the groundwater is mostly saline and brackish water, and the soil is highly salinized. Except for a small amount of salt-tolerant vegetation such as sparse Artemisia saponica, conventional vegetation is difficult to survive, and the ecology is extremely fragile. As the country's ecological construction continues to increase, the vegetation construction and restoration of degraded land such as saline-alkali land has become an important direction of e...

AI Technical Summary

Problems solved by technology

On the shallow groundwater saline-alkali land, the traditional vegetation construction method cannot solve the problem of salt drainage and salt return because the terrain and landform are not conducive to drainage. On the one hand, afforestation and grass are not easy to survive; The growth status is poor, the stability of the community is poor, and the requirements for ecological restoration cannot be met.
