通过田间试验研究了坡岗地宿根蔗营养调控技术。结果表明,单独施用配方肥、缓/控释配方肥,或配方肥配施有机肥、中微肥、调理剂的营养调控措施均可促进宿根蔗植株生长,蔗茎增高增粗,实现产量提高、品质优化目标;其中,配方肥配施有机肥、中微肥、调理剂的调控措施增产显著,应用配方肥配施中微肥营养调控措施的甘蔗品质最好。因此,在南方坡岗地糖蔗生产中,建立以配方肥配施中微肥、有机肥或调理剂为主体的“专用营养+土壤改良”调控技术具有积极的推广意义。
Field experiment was carried out to study the nutrition regulation of root and shoot sugarcane in slope land. The results showed that the nutrition regulation of single fertilizer, slow / controlled release fertilizer, or compound fertilizer with organic fertilizer, medium and micro-fertilizer, and conditioner could promote the growth of ratoon cane plant, increase the stem and stem and increase the yield , The goal of quality optimization; Among them, the formula fertilizer with organic manure, medium and micro-fertilizer, conditioner control measures to increase yield significantly, the application of formula fertilizer with the best nutrition and control measures in the regulation of sugar cane quality. Therefore, in the southern slope of sugar cane production, the establishment of fertilizer with fertilizer, fertilizer or organic fertilizer as the main “special nutrition + soil improvement ” regulation and control technology has a positive promotion.
