摘　　要：以紫花白作为供试品种,用3种植物生长调节剂在马铃薯初花期做叶面喷施,研究对其经济性状、产量和品质指标的影响。结果显示:在各处理中,保丰素处理的整体效果最好,单株块茎重最高达916.67g;产量达28 875 kg/hm2,较对照提高了17.02%;淀粉含量达16.28%,与对照相比增加了1.93个百分点;干物质含量达22.07%,与对照相比增加了2.04个百分点;块茎含水量为77.97%。通过丰收宝处理后,马铃薯的品质表现较好,单株结薯数最多为3.83个,商品薯率为91.84%,Vc含量最高为14.46 mg/100 g。Zihuabai as experimental material, leaf spray with 3 chemical regulators at first flowering time, was conducted to study effect to economic properties, yield and quality index. The results show： in every treatment, the whole effects of Baofengsu treatment was the best. The weight of per plant tuber reached 916.67 g,yield reached 28 875 kg/hm^2, compared with CK, the yield of Baofengsu treatment increased 17.02% ; The contents of starch reached 16.28% , compared with CK, the contents of starch of Baofengsu treatment increased 1.93 percent. The contents of dry matter reached 22.07%, compared with CK, the contents of dry matter of Baofengsu treatment increased 2.04 percent. The water content of tuber only reached 77.97%. The quality of potato by Fengshoubao treatment was better, the number of per plant was the most and reached 3.83, the ratio of commodity potato reached 91.84%, the content of vitamin C reached 14.46 mg/ 100 g.
