Effects of Altitude on pH Value and Available Nutrients in Chinese Hickory Orchards
在山核桃产区湍口镇开展了对山核桃林地土壤pH值和有效养分状况随海拔高度的动态监测。结果表明,在海拔220～330 m的范围内,随着海拔升高,土壤pH值呈明显的上升趋势,变幅为5.05～6.32。土壤速效氮、速效磷、速效钾和有机质则在海拔220～310 m表现出一定程度的下降,它们的变幅分别为土壤速效氮201.25～274.75 mg/kg、速效磷18.60～121.41 mg/kg、速效钾99.63～207.50 mg/kg、有机质26.87～4…查看全部>>
A dynamic mornitoring was conducted to examine soil pH value and nutrient availability changing with altitude in different Chinese hickory orchards of Tuankou town.Results showed that within the attitude 220～330 m of the increasing height,soil pH value increased obviously with the range of 5.05～6.32.Soil available nutrients of nitrogen（N）,phosphorus（P）,potassium（K） and organic matter（OM） decreased within 220～310 m with the ranges of 201.25～274.75 mg/kg,18.60…查看全部>>
