摘　　要：甘蔗是一种生长周期较长的茎用糖类原料,整个生长期有需肥量较大的特点。为实现甘蔗优质高产的目标,探讨了甘蔗施肥技术及施肥方案。甘蔗生长前期,要确保有足够的养分供应,增加甘蔗有效茎数;甘蔗生长伸长期生长较为迅速,甘蔗会出现明显的吸肥高峰,应通过科学施肥来促进甘蔗生长。在甘蔗的施肥中,要着重把握五大技术要点,即要施足底肥、早施提苗肥、稳施分蘖肥、重施攻茎肥、补施壮尾肥。根据甘蔗各生长时期的需肥特点进行科学施肥,可以为获得甘蔗优质高产提供坚实基础。Sugarcane is a sugar raw material for stems with a long growth cycle,which requires a large amount of fertilizer throughout the entire growth period.To achieve the goal of high-quality and highyield sugarcane,fertilization techniques and plans for sugarcane were discussed.In the early stage of sugarcane growth,it was necessary to ensure sufficient nutrient supply and increase the effective number of sugarcane stems;During the elongation period of sugarcane growth,it grows rapidly and exhibits a clear peak in fertilizer absorption.Scientific fertilization should be used to promote sugarcane growth.In the fertilization of sugarcane,it was important to focus on five key technical points,namely applying sufficient base fertilizer,early application of seedling fertilizer,stable application of tillering fertilizer,heavy application of stem attacking fertilizer,and supplementary application of strong tail fertilizer.Scientific fertilization based on the fertilizer requirements of sugarcane at different growth stages can lay a solid foundation for achieving high-quality and high-yield sugarcane.
