Description
Technical field
The present invention relates to the ecological, environmental protective science and technology field, be specifically related to a kind of blow sand build up fields and strand etc. in the original soil ecological afforestation method on heavy salinized ground.
Background technology
Blow sand and build up fields, refer to again reclaim land from the sea, be meant and on seabeach or shallow sea, build embankment isolating exterior seawater, and the water that eliminating is drained in the embankment makes the engineering that becomes land.The field saline and alkaline that but blowing sand builds up fields forms is very high, simultaneously, all the other field majority of strand be saline and alkaline very high in heavy salinizedly.In mainly contain chloride or sulphate in the heavy salinized ground, salt content is between 0.3%～3%.In in the heavy salinized ground content of organic matter few, soil fertility is low, physicochemical character is poor, the yin, yang ion harmful to crop is many, crop is difficult for short seedling, so heavy salinized ground trees are difficult for into alively in these, the greening difficulty is very big.
In the prior art, generally adopt three kinds of technological means centerings to afforest heavy salinizedly.
(1) soil moved in to improve the original is pressed alkali.Soil moved in to improve the original is exactly soil removal and replacement, and soil moved in to improve the original can improve the physical property in saline land, the salt of pressing down is arranged, drench salt, presses alkali and reinforcement, and the effect of soil fertility can make soil salt content be reduced to the degree of unlikely damage to crops growth.But soil moved in to improve the original presses alkali to lay materials such as stone, Polypropylence Sheet at the soil bottom of changing, and prevents saline and alkaline making a false countercharge, and it is loaded down with trivial details to construct, and cost is very high.In case saline and alkaline making a false countercharge, then all that has been achieved is spoiled.
(2) soil melioration.The method mainly is in the saline land, to increase continuously to execute a large amount of fertilizers, up to the suitable plant growth of the saline and alkaline of soil.But, in heavy salinizedly, this method takes effect slowly, and the amount of organic fertilizer of using is too big, cost is also very high, and suffers saline and alkaline making a false countercharge especially easily.
(3) washing salinity by irrigation.Be poured into water in the saline land, form the water layer of certain depth on ground, the salinity in the soil is fully dissolved, drain from the drain ditch the salinity of dissolving again, thereby reduce the salt content of soil.This method is very unrealistic at oceanfront, because the fresh water amount of oceanfront is original just few, and phreatic salt content is also higher, if quote the fresh water in other places in a large number washing salinity by irrigation is carried out in the saline land, loses more than gain, and saline and alkalinely makes a false countercharge easily.
Therefore need that a kind of cost of design is lower, better effects if in the greening method on heavy salinized ground.
