研究了在玉溪市烤烟种植后期分3个不同日期(7月20日、7月30日、8月9日)套种紫色甘薯的效益。结果显示:在7月30日进行烤烟套种紫甘薯栽培,可以获得最好的紫甘薯农艺和经济性状、较高的烟叶产量、最高的薯块产量以及最高的套种综合纯收入(59400.40元/hm2),比单作烤烟纯收入增加了17750.40元/hm2。 The effects of intercropping purple sweet potato in three different dates (July 20, July 30, August 9) during the late growing period of flue-cured tobacco in Yuxi City were studied. The results showed that the best purple potato agronomic and economic traits, higher leaf yield, highest tuber yield and the highest comprehensive income (59,400.40 yuan / hm2) were obtained on July 30, ), An increase of 17750.40 yuan / hm2 over the net income of single-purpose flue-cured tobacco.
