specific Embodiment 1

[0034] The medium-to-severe saline-alkali land medium-to-high-end original soil greening method specifically includes the following steps:

[0035] Step 1, taking samples to measure the salinity level of the project site, and determining the amount of soil bio-improvement agent for saline-alkali land;

[0036] Step 2. According to the local climate characteristics, grasp the law of water and salt movement, and determine the spraying time of soil anti-transpiration agent by analyzing the law of water and salt movement; the law of water and salt movement refers to the following table 1.

[0037] Step 3: According to the project and landscape needs and the soil salinity, combined with conventional saline-alkali-tolerant tree species, determine the tree species to be selected for the project. For the selection of tree species, please refer to the attached table 4.

[0038] Step 4, plan the planting method of tree species, preferably in the form of "hedge or pattern + arbor". Amo...

Abstract

The invention provides a mid-grade and high-grade greening method for moderate and severe saline-alkali soil. The method includes the following steps that firstly, sampling is carried out to measure the saline and alkaline level of an engineering area, the quantity of saline-alkali soil biological modifiers is determined, and soil improvement on the engineering area is carried out; secondly, the water-salt movement rule is determined according to local climatic characteristics, and spraying time of soil antitranspirants is determined by analyzing the water-salt movement rule; thirdly, the varieties of trees for engineering are determined according to engineering and landscape requirements and soil saline-alkali conditions in combination with conventional varieties of saline-alkali tolerant trees; fourthly, planting planning is carried out in the planting mode of hedges or carpet flower beds and trees. The mid-grade and high-grade greening method has a higher cost advantage than a method of external soil greening, engineering cost is remarkably reduced, and the phenomenon of saline-alkali back etching in the later period will not occur.

Description

technical field [0001] The invention relates to the field of ecological and environmental protection science and technology, in particular to a medium-to-high-end greening method for medium-to-severe saline-alkali land. Background technique [0002] my country's saline-alkali land area is nearly 100 million hectares and widely distributed, and it is increasing year by year. It is one of the largest saline-alkali land countries in the world. In recent years, with the development of tidal flat reclamation and sea reclamation, an average of 285 square kilometers of reclamation area has been added each year. Most of these saline-alkali lands are severely saline-alkali lands, and the natural environment is relatively harsh. Improving the investment environment through greening is the primary task of local governments in the construction of new areas. [0003] In 2012, the applicant applied for the patent of "original soil greening method", the patent application number is 201210...
