不同栽植密度对脱毒红薯产量及经济效益的影响

Effects of Planting Density on Yield and Economic Benefit of Sweet Potato with Virus-free

为确定三康8号脱毒红薯的最佳栽植密度并为其推广应用提供依据,采用大田试验方法,研究了不同栽植密度对脱毒红薯产量和经济效益的影响。结果表明:栽植密度为4 600株/667m2时,鲜薯产量高达2 577.9 kg/667m2,产投比高达2.37,是三康8号脱毒红薯的最佳栽植密度。

Yield and economic benefit of Sankang 8,a sweet potato variety with virus-free,was tested under different planting density by the field experiment method to determine the optimum planting density and provide a basis for its popularization.The results showed that the yield could be up to 2 577.9 kg/667m^2 under the density of 4 600 plants/667m^2 and its input/output ratio was up to 2.37.Therefore,the optimum planting density for Sankang 8 should be 4 600 plants/667m^2.
