Abstract
The invention discloses a quick desalination method of coastal beach saline-alkali, comprising the following steps: excavating ditches in a saline-alkali soil area, adopting mechanical plowing with the plowing depth of 25cm in a coastal beach saline-alkali area, flattening land and adopting a single line furrow-excavating method to reduce the moisture evaporation surface of the soil; excavating ditches at the two sides of the furrows, and taking the direction which is convenient for smooth drainage; and firstly planting ryegrass or sesbania to cultivate the soil, smashing the plant stalks of the ryegrasses or the sesbania to apply to a farmland, and growing salt-resisting deciduous tree seeds in a saline-alkali field. The invention can effectively enable the coastal beach saline-alkali to be quick desalinated; and carrying out operations based on the method in the invention for two years, salt content in the coastal beach saline-alkali area is reduced averagely from 12.1% to 3.4%.
Description
Technical field:
The present invention relates to the method that a kind of seabeach is coated with saline and alkaline quick desalination.
Background technology:
The worldwide problem that the saline and alkaline mankind of being in soil face, worldwide salt-soda soil distributes very wide, spread all over more than 30 countries in six big states, the gross area reaches 9.56 hundred million hectares, and it is world's concerned countries and and the focus be concerned about very much of mechanism that revegetation and development and use are carried out in the salt-soda soil always.
Summary of the invention:
The object of the present invention is to provide a kind of method that can make the coastal beach saline-alkali quick desalination of making of coastal beach saline-alkali quick desalination.
Technical solution of the present invention is:
A kind of method that makes coastal beach saline-alkali quick desalination is characterized in that: comprise the following steps:
(1) excavate irrigation canals and ditches in the zone, salt-soda soil, irrigation canals and ditches divide backbone, secondary main, branch line, 30 meters of trunk live widths of irrigation canals and ditches, dark 3 meters, and wide 7 meters, dark 1.5 meters of secondary main, 1.5 meters of a live width, dark 0.6 meter, the line line links to each other, and communicates with outer river;
(2) adopt machinery to turn over to coastal beach saline-alkali ground, ploughed depth 25cm levels land again, takes single file to do the furrow method and reduces the soil water evaporation face; Furrow both sides trench digging, direction is advisable with the draining smoothness;
(3) plantation rye grass or sesbania are cultivated soil earlier, and the plant stalk of rye grass or sesbania is smashed also field, carry out the salt-soda soil with the salt tolerant deciduous species again and plant on the spot.
The sowing quantity of rye grass is 3 jin every mu, and the consumption of sesbania is 7 jin every mu.
Described salt tolerant deciduous species is the bamboo willow, every mu of plantation 4000 strains.
The present invention can effectively make coastal beach saline-alkali quick desalination, by the inventive method operation 2 years, makes coastal beach saline-alkali ground salt content drop to 3.4% from average 12.1%.
The invention will be further described below in conjunction with embodiment:
The specific embodiment:
A kind of method that makes coastal beach saline-alkali quick desalination comprises the following steps:
(1) block is divided in the salt-soda soil, excavated irrigation canals and ditches in each salt-soda soil block, irrigation canals and ditches divide backbone, secondary main, branch line, 30 meters of the trunk live widths of irrigation canals and ditches, dark 3 meters, wide 7 meters, dark 1.5 meters of secondary main, 1.5 meters of a live width, dark 0.6 meter, the line line links to each other, and communicates with outer river;
(2) adopt machinery to turn over to coastal beach saline-alkali ground, ploughed depth 25cm levels land again, takes single file to do the furrow method and reduces the soil water evaporation face; Furrow both sides trench digging, direction is advisable with the draining smoothness;
(3) plantation rye grass or sesbania are cultivated soil earlier, and the plant stalk of rye grass or sesbania is smashed also field, carry out the salt-soda soil with the salt tolerant deciduous species again and plant on the spot.
The sowing quantity of rye grass is 3 jin every mu, and the consumption of sesbania is 7 jin every mu.
Described salt tolerant deciduous species is the bamboo willow, every mu of plantation 4000 strains.
