摘　　要：以马铃薯费乌瑞它为材料,叶面喷施生长调节剂,研究生长调节剂对马铃薯块茎质构特性、薯块商品率、产量、淀粉含量的影响。结果表明:这两种生长调节剂对马铃薯块茎的质构特性有一定影响,能降低块茎的硬度,增加块茎淀粉含量,块茎硬度和淀粉含量呈显著负相关。生长调节剂果然多能明显增加薯块商品薯率,天达2116能增加马铃薯产量,较常规栽培增产12%。Using potato "Favourite" as material, the effects of growth regulators on the texture characteristics, commodity rate, yield and starch content of potato tubers were studied. The results showed that the two growth regulators had a certain effect on the texture characteristics of potato tubers. They could reduce the tuber hardness and increase the tuber starch content. There was a significant negative correlation between tuber hardness and starch content. The growth regulator "Guoranduo" can significantly increase the commercial potato rate of potato chips, and "Tianda 2116" can increase the potato yield, which is 12% higher than that of conventional cultivation.
