摘要
两种保水剂在甘蔗上的应用效果试验结果表明:施用保水剂处理均能促进甘蔗出苗、分蘖及蔗茎伸长,增加有效茎数,同时能提高土壤含水量和肥料利用率;蔗茎产量比不施保水剂的对照增产2.84%～9.25%,蔗糖分提高0.09～0.40个百分点;经济效益比不施保水剂的对照增加652～2 207元/hm2。两种保水剂相比,BJ2101L保水剂在甘蔗上应用效果较好。
The present study was conducted to investigate the results of applying two water retention agents on sugarcane and provide a theoretical basis and reference of the application with water retention agent on sugarcane production.The results showed that the germination,tillering and millable stalks,meanwhile the soil moisture content and the utilization ratio of fertilizer were increased by applied water retention agents;the cane yield,sugar yield and the economic benefit was higher of 2.84%～9.25%,0.09%～0.40% and 652～2 207 yuan/hm2 than CK which it was without water retention agent,respectively.But the effective of BJ2101L water retention agent was better than the other on sugarcane.
