氮钾肥用量和栽培密度对鲜食型马铃薯新品种云薯103产量的影响

Effects of Nitrogen and Potassium Fertilizer Usage and Plant Density on Yield of Fresh-food Potato New Variety Yunshu103

[目的]为促进鲜食型马铃薯新品种云薯103的推广应用。[方法]应用3因素3水平正交设计,进行云薯103的氮钾肥用量、密度的研究。[结果]影响云薯103产量的主要因素是密度、氮肥用量,次要因素是钾肥用量。[结论]云薯103产量和经济效益最高的栽培技术方案为密度57 420株/hm2,尿素300 kg/hm2,硫酸钾600 kg/hm2。

[Objective] The research aimed to promote the application of the fresh-food potato new variety Yunshu103.[Method]Using three factors and three levels of orthogonal design,the study of nitrogen,potassium amount and density of yunshu103 was carried out.[Result] Major factors impacting the yield of Yunshu103 were density and nitrogen amount,and the secondary factor was potassium amount.[Conclusion] The cultivation technology program with the best production and economic benefits of yunshu103 was density of 57 420 plants/ hm2,urea of 300 kg/hm2,and potassium sulfate of 600 kg/hm2.
