摘　　要：甘蔗由于长期连作,生产中施用大量化肥,生物有机肥少施或不施造成蔗地土壤板结、酸化、沙化、土壤营养比例失调,土壤功能弱化、出现重茬障碍等,最终导致甘蔗产量和糖分降低。增施生物有机肥,合理配施氮、磷、钾肥,可有效保证土壤养分平衡供给,促进甘蔗生长,提高甘蔗产量和糖分。蔗地增施生物有机肥试验结果表明,与对照相比,增施生物有机肥可促进甘蔗增产10.865~22.585t/hm^(2),增产率为15.02%~31.22%;蔗糖分增加0.41%~1.01%(绝对值),增产增糖效果显著。Little or no application of bio-organic fertilizer resulted in soil compaction,acidification,desertification,maladjustment of soil nutrition,weakening of soil function and continuous cropping obstacle,which eventually led to the decrease of sugarcane yield and sugar content,The application of biological organic fertilizer and nitrogen,phosphorus and potassium fertilizer can effectively guarantee the balanced supply of soil nutrients,promote the growth of sugarcane and increase the yield and sugar content of sugarcane The results showed that the yield of sugarcane increased by 10.865-22.585t/hm^(2),the yield increased by 15.02%-31.22%,the sugar content increased by 0.41%-1.01%(absolute value),and the yield and sugar increased significantly.
