摘要： The coastal area of northern Jiangsu is rich in land resources. Meanwhile, Poplar-Agricultural compound management is an efficient and ecological management mode. Thus, it is of great significance to explore the application of agroforestry in different specific soil types in the coastal areas of northern Jiangsu. This study was conducted to investigate the dynamics changes of soil quality and crop growth physiology in eight Poplar-Agricultural complex management mode (Poplar pure forest (CY), Populus L. + Arachis hypogaea (YH), Populus L. + Glycine max (YD), Populus L. + Ipomoea batatas (YS) under coastal silt soil and CY*, YH* YD*.YS* under desalted soil after initial fresh water treatment). The results indicate that under the same soil conditions, compared with pure forests, the effects of Poplar-Agricultural compound management on soil physical and chemical properties were more significant. The growth status of trees was generally better under the condition of desalted soil and the survival rate was 35%-40% higher than that of saline soil. However, the survival rate of trees under the combined management of forestry and agriculture was 5%-10% higher than that of pure forest under the same soil condition. The microenvironment and crop photosynthesis were significantly affected by site conditions. Specifically, microenvironment was more stable under the condition of desalted soil and the photosynthetic effect of crops was better than that of silt soil. Overall, desalinized soil was more suitable for the growth of poplar plantation than silt soil, and Poplar-Agricultural compound management improved soil and forest environment which was better than pure poplar plantation. The study demonstrates that Poplar-Agricultural compound management plays an important role in improving soil quality and crop photosynthesis, and the selection of suitable specific soil conditionals can provide fundamental information for the sustainable development and management of agroforestry model in costal mudflat reclaimed lands.
