| 摘 要： | 【目的】研究影响甘蔗幼苗失绿的土壤因素,为克服失绿现象提供科学依据。【方法】对广西南宁、崇左、来宾等地甘蔗发生幼苗失绿问题的土壤营养进行调查研究,分析土壤pH值、铁、铝、锰和有机质含量等与甘蔗失绿现象的关系。【结果】甘蔗幼苗失绿病发土壤多属强酸性土壤,活性铝、交换性锰水平较高;土壤有机质、氮磷钾全量和有效水平总体上属于中高等水平;土壤有效铁含量不高,而与土壤有机质含量呈极显著正相关。【结论】甘蔗幼苗失绿可能与强酸性土壤中过多的活性铝、锰及高效整合铁有关。

| Abstract: | Objective]The studies were conducted to elucidate the causes of chlorosis in sugarcane in order to alleviate its effects and to develop some control measures. Method]Some soil physico-chemical characteristics such as pH and organic matter content and soil's nutrient status was analyzed during the early growth period of sugarcane planted in Nanning, Chongzuo and Laibin,Guangxi(China). Result]The soils cultivated with sugarcane exhibiting chlorotic symptoms were found strongly acidic with higher levels of ... |
