摘　　要：为了科学引导平坝区植物生长调节剂在马铃薯生产上的应用,增加粮食产量的同时保障粮食安全,以马铃薯“费乌瑞它”为主要试验材料,综合比较不同植物生长调节剂对马铃薯生长特性、农艺性状、产量及品质的影响,筛选适合平坝区冬作马铃薯的施药方法。结果表明,植物生长调节剂均能有效降低马铃薯植株株高,增加主茎粗壮程度,提高马铃薯产量;同时对品质方面均有不同程度的增加,但多效唑、矮壮素、胺鲜酯会降低马铃薯商品率。综合考虑商品率与产量指标,1 500 mg/kg氯化胆碱处理是最佳的外施方案。To scientifically guide the application of plant growth regulators in potato production in Pingba District,increase grain yield while ensuring food security,the potato‘Feiwuruita’was used as the main experimental material to comprehensively compare the effects of different plant growth regulators on potato growth characteristics,agronomic traits,yield,and quality,and to screen suitable application methods for winter potatoes.The results showed that plant growth regulators could effectively reduce the height of potato plants,increased the thickness of main stems,and improved potato yield.At the same time,there had been varying degrees of improvement in terms of quality.However,paclobutrazol,dwarfing hormone,and aminobutyric acid would reduce the commodity yield of potatoes.Taking into account both product yield and output,the optimal external application regimen was 1500 mg/kg choline chloride treatment.
