林地转变为茶园对土壤理化性质的影响
Effect of Converting Forestland to Tea Plantation on Physiochemical Properties of Soil
摘要
Abstract
Physiochemical properties of the soil in response to the changed land use from forestry to tea plantation were studied in Zhouning and Zhenghe counties, Fujian, China.Samples of soil from 0-20 and 20-40 cm depths at the plantations with varied utilization histories were collected for the study.The soil properties were found to vary significantly due to the conversion.The pH decreased significantly and seriously acidified the soil.The waterretention capacity, moisture content, total and capillary porosities, organic matters, and available potassium in the soil decreased significantly as well.However, these conditions improved with time.For instance, in 3 years after the conversion the alkali-hydrolyzable nitrogen and available iron decreased in the soil, but those at a 30-year-old tea plantation recovered and significantly increased.Similarly, the available phosphorus also increased continuously as the years gone by.The analysis of variance indicated that the location, depth and type of soil affected the physiochemical properties significantly, particularly the soil type.The observations suggested that tea farmers of a newly established plantation should increase the utilization of organic fertilizers to help enhance the soil fertility and structure while maintain an appropriate pH.关键词
