为新平县甘蔗种植施肥、土壤管理提供依据，通过对植蔗区土壤耕层取样，依据我国第二次土壤普查制定的土壤养分丰缺指标进行养分含量分析。结果表明，新平县植蔗区有51．76％的土壤偏酸，50．88％的土壤有机质偏低，45．88％的土壤碱解氮缺乏，26．47％的土壤缺磷，50．29％的土壤缺钾，37．14％的土壤缺硫，12．86％的土壤缺镁，94．29％的土壤缺硼，10％的土壤缺锰，31．43％的土壤缺锌。甘蔗生产中应注意增施有机肥、钾肥，以培肥地力，补施硼肥，保持土壤养分平衡。

To provide the basis for fertilization and management of sugarcane planting soil,the nutrient contents in topsoil were analyzed according to soil nutrient indexes established in the second general survey of soil.The results showed that in Xinping sugarcane planting area 51.76% soil was acid. Soils with low contents of OM,alkali-hydrolyzable nitrogen,P,K,S,Mg,B,Mn and Zn accounted for respectively 50.88%,45.88%,26.47%,50.29%,37.14%,12.86%,94.29%,10% and 31.43%.In sugarcane production it was essential to increase the application amounts of OM,K and B fertilizers,so as to enhance the soil fertility and balance the soil nutrition.
