摘    要:对我国北方泥质海岸盐渍土改良措施及效应研究表明,重盐土筑海堤栽植柽柳,苏打盐渍土的筑台田整地后采取覆山皮土、压稻乱栽植沙枣等固氮树种,轻中盐土台穴整地等方法是防治盐渍土的最佳的生态工程措施。经过定位测试表明,其降盐、增加养分、改善通透性、降低黏粒重量等效果显著。

关 键 词:泥质海岸  盐渍土  改良措施

STUDY ON AMELIORATION EFFECT OF SALT-AFFECTED SOIL ON ARGILLACEOUS SEASHORE ON NORTHERN CHINA
Abstract:Amelioration measure and effect of salt affected soil on argillaceous seashore in northern China was studied.The result showed:these methods,such as digging big holes in the sea dike in strongly saline soil to plant Tamarix chinensis,building platform in alkalized solonchak for site preparation and covering it with surface mountain soil to plant Elaeagnus angustifolia,and site preparation in light and medium solonchak were best ecological engineering measures to prevent salt-affected soil.The located test proved that effect of these measures for decreasing salt,increasing rapidly available nitrogen and phosphate,improving perviousness,and reducing clay content was very remarkable.
Keywords:argillaeous seashore  salt-affected soil  amelioration measure
