Abstract:
Aiming at soil in apple-pear orchard of Hunchun city of Korean Autonomous Prefecture of Yanbian of Jilin Province,mined soil profile in apple-pear orchard,collected soil samples from different soil genetic horizon according to soil properties,determined organic phosphorus fractions with improved Bowman-Cole method.The results showed that organic phosphorus content of wasteland was higher than that in apple-pear orchard within same soil horizon.The content of different organic phosphorus fractions showed a downward trend along with increasing depth of soil horizon in apple-pear orchard and wasteland.Labile organic phosphorus was more easily absorbed by plants among organic phosphorus fractions.The proportion of each organic phosphorus fractions accounting for total phosphorus was different,the common was that the percentage of moderately labile organic phosphorus accounting for total phosphorus was the highest,moderately labile organic phosphorus was the most important form of organic phosphorus in apple-pear orchard soil of Hunchun city of Korean Autonomous Prefecture of Yanbian.
