不同扦插密度对商薯19产量及经济效益影响分析

Analysis on Effect of Different Cutting Densities on Yield and Economic Benefit of Sweet Potato‘Shangshu 19’

为了丰富商洛市甘薯品种类型,大面积推广商薯19,筛选出商薯19在商洛市川道地区的最佳扦插密度,试验从5个密度水平,7个经济指标进行系统研究,通过对商薯19经济性状、品质性状、667 m^(2)产量和经济效益调查结果分析,发现品种在4500株/667 m^(2)密度下产量最高、经济效益最好。

In order to enrich variety types of the sweet potato in Shangluo,promote the planting of sweet potato‘Shangshu 19’on a large scale,and screen out its best cutting density in the flat areas of Shangluo,an experiment has been conducted to systematically study sweet potato‘Shangshu 19’from the perspective of five density levels and seven economic indicators.Through a comprehensive analysis of the research findings in the economic characteristics,quality traits,yield per 667 m^(2) and economic benefits of sweet potato‘Shangshu 19’,it is found that sweet potato of this type produced the highest yield and the best economic benefit at a density of 4500 plants/667 m^(2).
