摘　　要：通过田间试验研究了坡岗地新植糖蔗营养调控技术。结果表明,将配方肥单独施用,或配方肥配施有机肥、调理剂、中微肥可促进甘蔗植株生长,增加株高、商品茎长、基部粗度和有效茎数,实现甘蔗增产增收。采用长效化配方肥及两次施肥方法不利于甘蔗发育,导致平产或减产,效益降低。建议在坡岗地糖蔗生产方面应采用配方肥配施有机肥、土壤调理剂或中微肥。Field trials were conducted to study nutritional regulating techniques for upland newly planted sugarcane production. It was observed that the specific-fertilizer application alone, or with soil regulator, manure, midium and micro-nutrients promoted the growth of sugarcane in comparison with farmers’ normal fertilization, and increased the plant height, length and width of stem, the number of stem, and yield respectively. slow and controlled pecific-fertilizer, applied 60% fertilizers as base fertilizer and top dressing with 40% fertilizers in May, could not be conducive to sugar cane development, led to decreasing the profit in comparison with farmers’ normal fertilization. Proposed upland sugarcane production should be used pecific-fertilizer in combanition with manure, soil regulator, or midium and micro-nutrients.
