Abstract

Abstract: The soil salt and nutrient of 5-year-old Nitraria sibirica stand growing in heavy salinized soil were measured.The result showed that soil salt content(0～20 cm soil depth) of 5-year-old Nitraria sibirica stand decreased significantly and the soil nutrient content increased obviously compared with the unafforested land.In the neo-alluvial land area,the soil salt and nutrient of different types of forest stands afforested 18 years ago were measured.The result showed that the soil salt decreased significantly and soil nutrient increased obviously in different stands.Although the effects on controlling soil secondly salinized were no difference among the different stands,the content of soil organic matter and available nitrogen of poplar and acacia mixed stand row by row was the highest among all kinds of stands.

Key words: Yellow River Delta, afforest, soil salt, soil nutrient
