摘  要：
减肥减药是马铃薯绿色发展的一项重要措施。通过引进6种马铃薯减肥减药新型材料,与当地常规用药(CK_1)和清水喷洒(CK_2)进行对照试验,研究不同减肥减药新型材料对马铃薯生长特性及产量的影响。试验结果表明,阿泰灵、SC108农药控失剂、奇善宝海洋寡糖3种处理表现最好。相比CK_1和CK_2,阿泰灵处理产量分别提高7 076和12 955 kg/hm~2,增产率分别达到24.37%、55.94%;SC108农药控失剂处理产量分别提高5 432和11 311 kg/hm~2,增产率分别达到18.71%、48.84%;奇善宝海洋寡糖处理产量分别提高6 560和12 439 kg/hm~2,增产率分别达到22.59%、53.71%。3种处理虽对晚疫病、早疫病的防治效果不及常规用药,但能减少用药次数,降低用药成本。

摘  要：
Fertilizer and fungicide reduction is an important measure for green development of potato. By introducing six fertilizer and fungicide reducing materials and comparing with locally conventional fungicide application(CK_1) and water spraying(CK_2), the effects of different new materials on growth characteristics and yield of potato were studied. The performance of Alternaria, SC108 fungicide control-loss agent and Qishanbao oligosaccharide were best. Compared with CK_1 and CK_2, the yield under Alternaria treatment increased by 7 076 kg/ha and 12 955 kg/ha and the yield increased rates were 24.37% and 55.94%, respectively; the yield under SC108 fungicide control-loss agent treatment increased by5 432 kg/ha and 11 311 kg/ha and the yield increased rates were 18.71% and 48.84%, respectively; the yield under Qishanbao oligosaccharide treatment increased by 6 560 kg/ha and 12 439 kg/ha, and the yield increased rates were22.59% and 53.71%, respectively. Although the control effects of the three treatments on late blight and early blight were less than those of conventional fungicide application, they could reduce the times of fungicide application, and therefore the cost of fungicide application.
