Status and Temporal-spatial Variation of Organic Matter of Cultivated Soil in Hangzhou
摘要
Abstract
In order to understand the status of organic matter in the cultivated soil in Hangzhou, variation characteristics of organic matter content of whole cultivated soil was analyzed using soil test data recently obtained from soil fertility survey. The results showed that the level of organic matter of cultivated soil in Hangzhou was mainly medium, organic matter of most cultivated soil belonged to the level of 20-40 g/kg, and about 1/4 (27.00%) soil had a low level of organic matter. Average content of organic matter followed the order of water net plain > hills and valley plain > coastal plain. Organic matter of paddy soil decreased since the second national soil survey, while the average content of organic matter in upland increased. It was concluded that soil organic matter in Hangzhou varied greatly. Input of organic fertilizers to paddy field should be increased to prevent further decline of soil organic matter, and more attention should be paid to improve organic matter of cultivated soil in the coastal plain.关键词
