浙北地区不同土地利用方式对土壤理化性质的影响
Effects of Different Land-use Types on Soil Physiochemical Properties in Northern Zhejiang Province
摘要
Abstract
In order to study the characteristics of soil nutrient changes under different land-use types in Northern Zhejiang Province,soil physiochemical properties of paddy fields,irrigable fields and orchards were measured,including pH,organic matter(OM),total nitrogen(TN),available phosphorus(AP),available potassium(AK),bulk density(BD),cation exchange capacity(CEC)and water-soluble salt.The results showed that:1)pH was in an order of orchard＞paddy field＞irrigated field,pH of irrigated field was significantly lower than those of orchard and paddy field;2)OM was in an order of paddy field＞orchard＞irrigated field,OM of paddy field was significantly higher than those of orchard and irrigated field;3)There was no significant difference in TN among the different land-use types,AP was in an order of irrigated field＞orchard＞paddy field,AP of irrigated field and orchard were significantly higher than that of paddy field,AK was in an order of orchard＞irrigated field＞paddy field,AK of orchard was significantly higher than that of paddy field;4)There was no significant difference in BD,CEC and water-soluble salt between irrigated land and orchard.These results can provide a reference for the rational use of land resources,scientific application of fertilizers and high-quality development of agriculture in Northern Zhejiang.关键词
