摘　　要：选用泥炭、腐泥及其混合物3种天然有机物料作为风沙土改良剂,进行盆栽试验,评价不同处理对白菜生长状况和风沙土性质的影响。结果表明,施入泥炭和腐泥后的风沙土利于白菜生长,单施泥炭8%-12%、或单施腐泥28%-32%效果明显,混合施入12%泥炭＋28%腐泥的效果也较好,表现为风沙土的物理结构、pH有所改善,土壤中有机质、速效氮、磷、钾和腐植酸含量都有所增加;白菜的高度、根长、鲜质量和干质量明显优于对照。因此,认为泥炭和腐泥是风沙土的优良改良剂。The 3 levels of peat,11 levels of sapropel,3 levels of peatsapropel are added into aeolian sandy soil which Chinese cabbage is planted in.The growth status of Chinese cabbage in the pots and the physicochemical properties of different treatment of aeolian sandy soil are analyzed.The results indicate that application of peat and sapropel are good for the growth of Chinese cabbage.First,the structure of treated sandy soil,such as moisture,bulk weight and pH has greatly improved.Meanwhile,the content of organic matter,available N,P,K and HA in the treated sandy soil also obviously increased.On the other hand,the growth of Chinese cabbage is also satisfactory,the shoot and root is highly longer,the fresh weight and the dry weight are obviously higher than the contrast.Therefore,natural peat,sapropel are thought to be good sandy soil modifiers.The best treatment is considered as only 8%～12% peat,or only 28%～32% sapropel or the mixture of 12% peat and 28% sapropel added into sandy soil.
