摘要
本文汇集,整理了代表鲁西,北平原潮土的惠民、莘县、菏泽三地的土温资料,包括5cm、20cm、40cm 和80cm 土层逐月累年平均土温,年平均土温,最高最低土温和出现时间及土温年较差筹。分析了土温随时间、空间而变化的规律。并通过与其它地区土壤土温状况的对比,阐明鲁西,北潮土的土温特性。最后指出潮土土温在生产上的问题及可采取的增温、保温措施。
The data on soil temperatures of Chao soil in Huimin,Shenxian and Heze.three typi-cal counties of the western and northern parts of Shandong Province,are compiled andpresented,involving monthly and yearly mean soil temperatures of 24-30 years.the maxi-mum and minimum soil temperatures and time of its appearing,and the annual ranges ofsoil temperatures etc.The regular patterns of soil temperature changes with the time and lo-cations are analysed.In comparizon with those in other regions,the characteritics of Chaosoil temperature in the west and north of Shandong Province are described.The problemsin production arising from of Chao soil temperatures are presented,and available measuresfor increasing and maintaining soil temperature are suggested.
