摘要
[目的]研究不同栽培技术对铁棍山药生长和产量的影响.[方法]以河南温县的铁棍山药为材料,研究不同种植密度、不同施肥量及搭架与无架栽培对铁棍山药生产和产量的影响.[结果]最佳的种植密度为150075株/hm2,铁棍山药产量最高,为16 152.60 kg/hm2,商品率为69.96％.施用750 kg/hm2复合肥,单重、长度、直径均高于其他处理;施用l 500 kg/hm2复合肥,产量最高,为8 405.40 kg/hm2,但与施用750 kg,/hm2复合肥的产量差异不显著.搭架栽培比不搭架栽培产量增加27.42％,但增收不显著.[结论]铁棍山药在桂林地区生态环境下具有良好的适应性和推广价值.
Abstract
[Objective] The research aimed to study the effects of different cultivation techniques on growth and yield of iron stick yam.[Method] Using iron stick yam of Henan Wenxian as the experiment material,the effects of different planting density,different fertilization concentration and humping support and no humping support cultivation on the production and yield of iron stick yam were studied.[Result] The optimum planting density was 150 075 plants per hm2,the yield of iron stick yam was the highest(16 152.60 kg/hm2),the commodity rate was 69.96％.The single weight,length,diameter of the treatment of 750kg/hm2 compound fertilizer were higher than other treatment;but the yield of the treatment of 1 500 kg/hm2 compound fertilizerwas the highest,which was 8405.40kg/hm2,but there was no significant difference with the application of 750 kg/hm2 compound fertilizer.The yield of humping support cultivation increased 27.42％ than that of no humping support cultivation,butthe increase was not significant.[Conclusion] Iron stick yam has good adaptability and promotion value under Guilin provincial ecological condition.
