Soil Fertility Characteristics of Recreation Green Land in Xuchang
摘要
Abstract
The soil fertility characteristics of recreation green land were analyzed in Xuchang,so as to provide theoretical reference for research on soil nutrients and management of soil in urban green land.The conclusions were as follows:the content of available nitrogen ranged from 12.55 mg/kg to 176.44 mg/kg,with the mean of 54.74 mg/kg and the overall level was between the fifth and the sixth;the content of available phosphorus ranged from 4.61 mg/kg to 76.86 mg/kg,with the mean of 32.18 rng/kg and the overall level was at least the third; the content of available potassium ranged from 177.36 mg/kg to 477.54 mg/kg,with the mean of 324.23 mg/kg and the overall level was at least the first;the content of organic matter ranged from 16.48 g/kg to 78.87 g/kg,with the mean of 40.67 g/kg and the overall level was at least the second.The soil fertility composite index was 1.29 and the level was the third,indicating a common soil fertility.The advices for the management of recreation green land were planting green manure plants,increasing the nitrogen and manure application to improve the soil fertility and quality.关键词
