摘  要:
为了探讨不同栽插方式和栽插密度对甘薯产量和结薯习性的影响,以全国主栽品种商薯19为试验材料,采用2个因素完全随机设计方法,进行了6个处理的对比试验.结果表明,鲜薯产量和薯干产量均以平栽高密度处理最高,对鲜薯产量和薯干产量的影响大小表现为栽插密度>栽插方式;商品薯产量和商品薯率均以平栽低密度处理最高,对商品薯产量和商品薯率的影响大小表现为栽插方式>栽插密度.从试验看,平栽、栽插密度5.25万株/hm2组合有利于发挥商薯19的高产潜力;平栽、栽插密度3.75万株/hm2组合能让商品薯产量、商品薯率达到最高.

摘  要:
To explore the effects of different planting methods and planting density on the yield and tuber habit of sweet potato, a comparative experiment of six treatments of national main cultivar Shangshu 19 was conducted with completely random design of two factors. The results showed that the fresh root yield and dry matter yield with high density of horizontal planting were the highest, the two factors affected the fresh root yield and dry matter yield were planting density >planting methods. The commercial root yield and commercial root rate with low density of horizontal planting were the highest, the two factor affected the yield and yield of commercial potato were planting methods>planting density. In this experiment, horizontal planting with density of 52 500 plants/hm2 is conducive to play the high potential of Shangshu 19, both commercial root number and yield are the highest when horizontal planting density is 37 500 plants/hm2.
