Effects of Cultivation Modes and Planting Density on Potato Zhongshu 3 (Solanum tuberosum L.) in Winter Season

摘要: 以中薯3号为供试材料,采用双因素裂区设计,研究南方冬作区稻草包芯等4种不同栽培方式及密度对中薯3号的影响,结果表明:不同栽培方式及密度对中薯3号的产量、商品性等都有一定影响。该品种以稻草包芯栽培和密度7.5万株hm-2组合的产量效应较好,产量达47 925.0 kghm-2。综合考虑产量、商品薯率、商品性等因素,南方冬种区中薯3号最佳栽培方式宜采用稻草包芯,种植密度为6.75万~7.5万株hm-2。

Abstract: Split-plot design with two experimental factors was used to study the effects of four cultivation modes and planting density on potato cultivar Zhongshu 3 in Southern China.Results showed that the yield and commodity quality of potato were significantly different with four cultivation modes or planting density.Comparatively, the highest potato yield was 47 925.0 kghm-2 obtained by the mode of straw mulching as sandwich plus density in 75 000 plants per hectare.Based on the yield, commodity rate and quality of the potato comprehensively, the best cultivation pattern were the mode of straw mulching as sandwich with planting density of 67 500 to 75 000 plants per hectare.
