摘要

The soil fertility status in pear orchards of Jiaodong area was investigated and analyzed in this paper. The results showed that the pH value was between 4.17 and 6. 24, so the soil acidification was very serious. The content of organic matter was all higher than 10.0 g/kg, but the content of alkaline hydrolytic nitrogen was lack except that in Qixia pear orchards as 106. 2 mg/kg. The content of effective phosphorus was between 29.4 ~ 86.2 mg/kg, which were very rich. The content of available potassium was relatively rich except in Haiyang lower as 93.1 mg/kg. The content of exchangeable calcium was higher than 1 000 mg/kg in Penglai, Longkou and Laiyang,but lower in Muping and Weihai. The content of exchangeable magnesium was more appropriate in Muping, but lower in Weihai and higher in Penglai, Longkou and Laiyang. The content of effective copper was higher in Jiaodong aera, and the content of effective iron, effective manganese and effective zinc were more appropriate.%对山东省胶东地区梨园的土壤肥力状况进行了调查分析,结果表明:胶东地区土壤pH值在4.17~6.24之间,酸化比较严重;有机质含量普遍在10.0g/1kg以上;碱解氮含量除栖霞106.2mg/kg较适宜外,其他地区含量缺乏;土壤有效磷含量在29.4~86.2mg/kg之间,含量极丰富;土壤速效钾含量除海阳93.1mg/kg较低外,其他地区含量相对较丰富;蓬莱、龙口、莱阳果园土壤交换性钙都在1000mg/kg以上,但牟平、威海果园土壤交换性钙较低;交换性镁含量除牟平比较适宜外,威海市较低,蓬莱、龙口、莱阳则相对较高;胶东地区有效铜含量较高,有效铁、有效锰、有效锌含量普遍比较适宜.
