Investigation and Analysis of Soil Nutritional Status of Pear Orchard at Five Main Production Counties in Hubei Province

The soil nutritional status of pear orchard at five main production counties including Zhongxiang County,Jingshan County,Qianjiang County,Lichuan County,and Xuan-en County in Hubei Province were investigated and analyzed.The results showed that soil pH was 4.75~7.26,content of soil organic matter was 1.032%~2677%,content of alkaline hydrolysis nitrogen was 63.076~124.32mg/kg,content of effective phosphorus was 27.707~44.561mg/kg,content of available potassium(K)was 53.408 ~201.7mg/kg at pear orchard in five main production counties.Content of alkaline hydrolysis nitrogen was high,exchangeable magnesium,effective copper,available zinc were high while content of effective phosphorus,available potassium(K),available iron, available manganese were medium at the five main production counties.Content of exchangeable calcium was low at pear orchard in some counties.
