不同植物生长调节剂在马铃薯生产中的应用研究

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。

Application Study on Plant Growth Regulators in Potato Production

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/hm2,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.
