分析了甘蔗品种柳城05/136在传统施肥、一次性施肥和有机肥+复合肥+活力素3种施肥方式下的农艺性状、生理指标、产量和品质。结果表明,柳城05/136传统施肥下各项生理指标、品质都较其他2种施肥方式稳定,蔗糖分>15%;一次性施肥出苗率、蔗糖分均最低,但成茎率、甘蔗产量最高,单位面积含糖量和经济效益较高;有机肥+复合肥+活力素施肥方式的苗期出苗情况最好,有效茎数较多,叶绿素含量高于其他处理,产量和含糖量均处于中间水平。不同施肥处理下各生长期叶片全P含量差别不大,说明施肥处理对叶片P含量影响不大;叶片K含量在8-10月间基本呈上升趋势,说明活力素活化了有机肥和复合肥的有效养分并促进其释放。
The agronomic traits, physiological indexes, yield and quality of sugarcane variety Liucheng 05/136 under the three fertilization modes of traditional fertilization, one-time fertilization and organic fertilizer + compound fertilizer + vitamins were analyzed. The results showed that the physiological indexes and quality under Liuzhou traditional fertilization were all more stable than those of the other two fertilizers, and the content of sucrose was> 15%. The rate of emergence and emergence of sucrose was the lowest in one time, , Sugar content per unit area and higher economic benefits; organic fertilizer + compound fertilizer + vitamins fertilization mode seedling emergence is best, more effective stems, chlorophyll content than other treatments, yield and sugar content are in Middle level. The content of total P in different growth stages was not different under different fertilization treatments, indicating that fertilization had little effect on the content of P in leaves. The content of K in leaves tended to increase from August to October, indicating that activin activated organic and compound fertilizers Effective nutrients and promote their release.
