国内外甘蔗施肥技术研究进展

Research Progress of Sugarcane Fertilization Technology at Home and Abroad

甘蔗(Sugarcane)作为重要的经济作物之一,生产的食糖占到全球产量的80%。作为一种植株高大的作物,甘蔗生长较为旺盛,具有较强吸收水分和养分的能力,甘蔗需要的养分较多,主要以钾、氮和磷为主,且钾>氮>磷。但是由于施肥技术体系不完善,过量施用化肥导致土壤板结,甘蔗产量和品质逐渐下降。因此,为了改善目前的施肥现状、提高肥料利用率、提高甘蔗的产量和品质,合理的绿色施肥技术以及新型肥料研发对甘蔗生产显得尤为重要。本文主要介绍了国内外甘蔗施肥技术与肥料研发施用的研究进展,并对未来甘蔗的绿色智能施肥技术提出新的创新发展方向。

As one of the important economic crops,sugarcane accounts for 80%of global sugar production.As a kind of tall crops,sugarcane grows vigorously and has a strong ability to absorb water and nutrients.Sugarcane requires more nutrients,mainly potassium,nitrogen,and phosphorus,with potassium>nitrogen>phosphorus.However,due to the incomplete fertilization technology system,excessive application of fertilizers leads to soil compaction and a gradual decline in sugarcane yield and quality.Therefore,in order to improve the current fertilization status,increase fertilizer utilization rate,yield and quality of sugarcane,the research and development of new fertilizers and green and reasonable fertilization technology are particularly important in the entire sugarcane planting process.This paper mainly introduces the research progress of sugarcane fertilization technology and fertilizer research and development and application at home and abroad,and puts forward a new innovative development direction for green intelligent fertilization technology of sugarcane in the future.
