Method.
Background technique
The salinization of soil is a global environmental problem.According to incompletely statistics, whole world salinized soil area about nearly 10
Hundred million hectares.China is more serious one of the country of the salinization of soil, about 100,000,000 hectares of the gross area, is mainly distributed on northeast, China
North and Northwest inland area.Due to the needs of China human mortality rapid growth and national economy high speed development, construction land is increased sharply
Contradiction between cultivated land protection becomes increasingly conspicuous, in order to alleviate this conflict, it would be desirable to improve existing fertility or open
Cultivate new soil.Salt-soda soil is a kind of potential land resource, still has 80% or so salinized soil not to be utilized at present, if energy
It is reasonably developed and utilized, huge ecology and economic benefit can be brought.
Currently used alkaline land improving measure mainly includes four classes: 1. engineering ameliorative measures: as bored well of pouring water, building platform
Field, embedded hidden pipe etc..2. agronomy ameliorative measure: being built upon on the moisture and salt regime regular basis of " salt comes with water, and salt is gone with water "
, by different agronomy tillage methods, inhibiting or reduce the evaporation of soil moisture, the table for mitigating salinity is poly-, desalinate arable layer, into
And achieve the purpose that improvement.It mainly includes reasonable farming and cultivation technique, passes through the fields such as turn over, rake the soil level, suppress, intertill
Good soll layer structure is created in operation, promotes desalination；By measures such as Rational Irrigation, fertilising and ground mulchings, increase soil
Earth soil moisture content inhibits salt accumulation in surface soil, adjusts the hot situation of soil water fat gas, creates good soil environment for high crop yield.3. biology
Ameliorative measure: the selection of salt-tolerant plant is the premise of salt-soda soil biological modification, cultivates and plantation salt-tolerant plant changes salt-soda soil
Good utilization is particularly important.4. chemical modifying measure: being the method for improveing saline-alkali soil physicochemical property using acid-base neutralization principle.Its
