Description
Technical field
The present invention relates to landscape engineering field, especially a kind of varieties in saline-alkali areas plant pit modification method.
Background technology
Saline-alkali soil is also known as salinized soil, is the general designation of solonchak and alkaline earth.The salinization of soil does not only result in soil productivity decline,
And trigger many ecological environment problems, with the anxiety of land resource, the aggravation of atmosphere pollution, there is an urgent need to effective measures to change
Good salt affected soil.
The purpose of the reclamation of salinep-alkali soil will not only eliminate harmful salinity, also increase soil fertility.In fact, fertilizing helps
In eliminating harmful salinity, consolidate salt discharge effect, and salt discharge is a kind of important fertilizer application method in itself, is conducive to soil fertility
It improves, the two is mutually promoted.
The survival rate of planting plants compares relatively low in salt-soda soil, especially in landscape engineering, once geology
It is even whole to be improved for salt-soda soil, it can also lower plant percent, greening is difficult.
Planting technique is carried out on salt-soda soil, general processing method is exactly to carry out salt discharge and pressure salt method first to salt-soda soil
Deng, but above method still has some shortcomings, if salt discharge method is to rely on to rush salt-soda soil for a long time using substantial amounts of fresh water
Brush is so that the salt content of saline and alkaline surface layer lowers；Pressure salt method is using natural precipitation or manually a large amount of irrigations, promotes part salt
Divide along hole, crack of soil etc. to subsurface wastewater infiltration system, soil bottom to is taken the soil salt on surface layer by water；Above method
Nearly all to use to a large amount of water sources, while permanence operation is bad, even whole saline and alkaline is reduced but still needed to part
Plant pit is improved, and especially can utilize a kind of saving water resource, simple and easy to do while can increase again with respect to the slight area of salination
The construction technology of strong fertility.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of varieties in saline-alkali areas plant pit modification method.
In order to solve the above technical problems, the technical scheme is that：
A kind of varieties in saline-alkali areas plant pit modification method, is as follows：
(1) unwrapping wire, excavation
It determines plant pit position, nursery stock specification is adjusted according to plant pit specification, standard is 12 times of the nursery stock diameter of a cross-section of a tree trunk 1.3 meters above the ground for plant pit area；
(2) plant pit drenching layer is handled
Drenching layer is made of the net stone nitre and 30 grams every square metre of permeable non-woven fabrics of 0.8-1cm of 25cm thickness in plant pit, at this
Reason layer can play the role of water drenching, and can prevent secondary pollution of the plant pit bottom crude salt alkaline earth to conditioned soil；
(3) permeability cell is laid with
63 PVC blind pipes right-angled intersection is embedded to drenching layer, four venthole 10cm above ground level；
(4) soil improvement
Additive is mixed in soil improvement, the additive is mainly by the mountain skin sand of increase soil permeability, increase soil
The organic matter and turfy soil of microorganism, the desulfurated plaster of displacement sodium ion and ferrous sulfate composition, the weight ratio of each component is successively
For 50-80:70-100:20-50:5-15；
(5) soil fertility is increased
Fertilizer dedicated to alkaline land is carried out before plant to plant pit soil to mix to increase soil fertility reduction saline and alkaline.
Preferably, above-mentioned varieties in saline-alkali areas plant pit modification method, the weight ratio of each component is followed successively by 70 in the step (4):
90:35:10。
The beneficial effects of the invention are as follows：
Above-mentioned varieties in saline-alkali areas plant pit modification method mainly carries out original soil plant pit improvement to salt content in the soil of 3-10 ‰
So as to build Green Landscape, the desalinization of soil by flooding or leaching is efficient, with fresh water amount it is few, every salt alkali ability is strong, most the salt content of soil drops at last
To less than 3 ‰, promote nursery stock growth, the varieties in saline-alkali areas after improvement is allow to effectively improve whole greenery area, promoted whole big
Makings amount enhances garden landscape effect, increases salt-soda soil utilization rate.
Specific embodiment
Technical solution of the present invention is further described with reference to specific embodiment.
