摘要
[目的]为了研究营口地区不同马铃薯品种适种密度。[方法]采用4个马铃薯试验品种,设置3个密度梯度,分别测定了各密度处理下不同马铃薯品种株高、茎粗、单株块茎数、单薯重和产量。[结果]不同马铃薯品种随着种植密度的增加,株高呈现上升趋势,单薯重、产量、茎粗和单株块茎数先增加后降低。[结论]早大白、尤金、富金、费乌瑞它品种的最适种植密度为6万穴/hm^2。
[Objective] To study suitable density of different potato varieties for culture in Yingkou. [Methods] Four potato varieties were test under three different planting density. Plant height, stem diameter, tuber number per plant, weight of single chips and yield were measured. ]Results] With planting density increased, height of all the potato varieties increased, single tuber weight, yield, stem diameter and plant tuber number increased firstly and then decreased. [Conclusion] The best planting density of Zaodabai, Youjin, Fujin and Feiwuruita was 4 000 holes/667 hm^2.
