试验于1989年至1995年设置在辽宁渤海湾泥质海岸的轻、中、重盐碱土和苏打盐渍土4块试验地上。在盘锦市大洼县拦海防潮堤含盐量为10g/kg的重盐土上筛选柽柳为先锋树种,五年后土壤盐分下降到4g/kg左右。凌海市建业乡苏打盐渍土上沙枣可为抗碱耐涝先锋树种。在中盐碱地,群众杨、109柳与紫穗槐混交树高比纯林分别提高3%、10%;胸径提高12%、25%。轻盐碱地可栽种群众杨、绒毛白蜡、109柳、刺槐,建立速生丰产林基地。
The experiment was conducted on four plots of light, medium and heavy saline soil and soda saline soil from 1989 to 1995 at the muddy coast of Bohai Bay, Liaoning Province. Tamarix chinensis is the pioneer tree species in the heavy salt soil with a salt content of 10 g / kg in Dadu County, Panjin City. After five years, the soil salinity dropped to about 4 g / kg. Linghai Jianye Township soda saline soil sand date jujube resistant to alkali and waterlogging pioneer trees. In the saline-alkali land, the population poplar, 109 willow and Amorpha fruticosa hybrid tree increased by 3%, 10%, respectively; DBH increased by 12%, 25%. Light salinity can be planted poplar Young, fluff white wax, 109 willow, black locust, fast growing forest base.
