Description
Technical field
The utility model relates to saline land afforestation and restoration of the ecosystem field, particularly, relates to a kind of saline land desalting system.
Background technology
Saline land is important land resources, and it is a kind of soil types of extensively distribution on the earth, accounts for 25% of the land gross area, amounts to about more than 10 hundred million hectares, be distributed in arid area, different continents, mainly concentrate on Eurasia, Africa and Western North America.About there is 0.27 hundred million hectare, saline land in China, wherein 0.06 hundred million hectare of arable land, 0.21 hundred million hectare of saline-alkali wasteland, is mainly distributed in northeast, North China, Northwest inland area and North of Yangtze River coastal area.
In salinized soil solution, lyotropic salt increases, and concentration and osmotic pressure increase, and cell is difficult to absorb moisture, and blade can be caused thickening, and air vent aperture reduces, the generation of the symptoms such as trophic disturbance and various nutritional deficiency diseases.The salinization of soil in soil, decreases surface vegetation, increases evaporation discharge, causes some areas humidity to decline, the generation of arid, forms the harm of dry-hot wind, the normal development of the restriction ecological balance.
Domestic alkaline land improving Application way and technology are summed up roughly as follows:
(1) level land, deep plough sun the earth which has been ploughed up, loosen the soil in time, raise landform, microcell is improved the soil;
(2) water conservancy improvement, fills with deploying cover, storage fresh water on saline-alkali land for leaching, washing salinity by irrigation, underground salt discharge;
(3) chemical modifying, uses gypsum, ardealite, superphosphate, humus, peat, acid-sludge etc.;
(4) biological modification, the salt-tolerant plant such as rice cultivation, sesbania, uses microbial-bacterial fertilizer etc.
Multiple technologies and the measure of the alkaline land improvings such as river construction measure, agrotechnical measures, biological control measure, chemical modifying have different improved effects.In the measures of improvement saline-alkali soil, from renovation dynamics, the salt discharge effect in saline land with promote the use of scope, in multiple alkaline land improving technical method, utilizing works Drainage of salt is main technical measures.But from the utilization of water conservancy improving technology and development, this improving technology is it follows that a kind ofly continued the principle and method that more than one thousand years do not change, and Here it is, and " salt comes with water, and salt goes with water; Salt comes with water, and the water salt that falls apart stays " water salt run basic law, substantially thoroughly cannot solve the saline and alkaline harm to plant, other improvement methods are owing to cannot isolate background impact, and improved effect is also stable not, exists repeatedly.
