Preparation Method.
Background technology
Saline-alkali soil is solonchak and the general name of alkaline earth and various salinization, alkali-affected soil.Solonchak refers to soluble organic fraction in soil
Content reaches to a certain degree, and the g and D of plant can be produced with the great soil group of substantially harm.Alkaline earth refers to contain greatly in soil
Amount commutativity ion, quantity reaches the degree that can endanger plant growing and develop, and makes the soil that soil property changes.
The salinization of soil of soil refers to due to a large amount of accumulation of salt basic ion in soil, the process that soil types gradually changes to saline-alkali soil, its
Influence factor includes natural cause and anthropic factor.Easily hardened phenomenon in salt affected soil under normal circumstances, leads to soil
Porosity diminishes, and the gas permeability of soil and water penetration are deteriorated, and badly influence the metabolism of Soil Microorganism, reduce the work of various enzymes
Property and the mineralization degree of carbon, nitrogen, the conversion of soil with organic matter is slack-off, eventually results in soil increasingly barren.Soil contains
The a large amount of salt ions having also can badly influence the normal physiological function of salt-soda soil plant, suppresses its g and D.In addition, with
The development of social economy and the continuous aggravation of mankind's activity, saline alkali land resource increasingly receives publicity, irrational irrigation is made
Degree also results in Pedotransfer function aggravation.Second Committee International Sustainable Development conference is just pointed out, following meeting seriously threatens the world
