Technical field
The invention belongs to technical fields of planting trees, and in particular to a kind of heavy saline-alkali area at seashore raised fields method of forestation.
Background technique
Salination is a kind of types of presentation of desertification, and coastal saline-alkali beach habitat is severe, be always afforestation the most
Difficult location.Heavy saline soil salt is generally 5/1000ths or more, to improve the heavy saline surrival rate of afforestation and preservation
Rate generally uses ditching, drenches salt by rainwater, reduces the salinity in soil.
A kind of coast saline-alkali soil forestation method is just described in Chinese granted patent CN101322470B, including is walked as follows
Rapid: A, trench digging builds back, builds collection rain bed；B, setting collection rain face；C, plant pit is dug, is arranged every salt deposit；D, Tree Species Selection and plant；E,
Plant pit surface coating is set；F, field management, in due course weeding；Wherein: the trench digging builds back, and building collection rain bed step is root
According to the design of afforestation seeding row spacing, along capable trend using line-spacing as alternation excavation afflux ditch, bottom of trench depth 20cm~25cm arranges back ridge
Ground between bottom of trench is made shallow v font groove, and leveling makes real slope surface, forms collection rain bed.Although can be mentioned using this method
The survival rate and storage rate of high forest, but there is still a need for subtract steaming by the collection rain desalinization of soil by flooding or leaching, setting separation layer resistance salt and ground surface covering
The mode combined that preserves soil moisture is afforested.There is no a kind of simple and easy heavy saline-alkali area at seashore method of forestation at present.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of heavy saline-alkali area at seashore raised fields method of forestation, it is easy to operate, it shows
Writing reduces seedling root layer soil salt content, improves the surrival rate of afforestation and storage rate, guarantees the normal growth in nursery stock later period, improves
Ecology and economic benefit.
In order to achieve the above-mentioned object of the invention, the present invention the following technical schemes are provided:
The present invention provides a kind of heavy saline-alkali area at seashore raised fields method of forestation, comprising the following steps: in strand geavy salt alkali field
Middle several raised fields of setting, transplant nursery stock on the raised fields；The raised fields lower surface paving every salt deposit, cover by the raised fields upper surface
Film.
Preferably, a height of 1~1.5m of the raised fields, the longitudal section of the raised fields are trapezoidal, the trapezoidal upper bottom width
