不同株行距对甘薯生长和产量性状的影响
Effects of Plant-row Spacing on Growth and Yield Characters of Sweet Potato
摘要
Abstract
Under the experimental conditions of row spacing 0. 8 ～ 1.0 m and plant spacing 0. 15 ～0. 25 m in Hainan province,the effects of nine different plant - row spacing treatments on the growth and yield characters of short - vine type sweet potato variety Guangshu 79 were studied. The results showed that widening row spacing was advantageous to improve the number of base branches,fresh root weight per plant, dry matter rate, yield of dry root slice and starch yield. Reducing plant spacing was propitious to improve the yield of fresh root and dry root slice; on the other side, widening plant spacing was advantageous to improve the number of base branches, root number per plant, fresh root weight per plant and the proportion of big and medium roots. Among 9 treatments, 0. 8 m × 0. 15 m plant - row spacing treatment harvested the highest fresh root yield, and (0. 9 ～ 1.0 m) × (0. 15 ～0.20 m) plant - row spacing treatments harvested higher yield of dry root slice and starch yield.关键词
