摘要
为了研究植物生长调节剂与肥料对羊草(Leymus chinensis L.)增产的影响程度,试验采用正交的设计方法将多种植物生长调节剂与水溶肥、矿物油和渗透助剂进行组合,得出具有大田可操作性的羊草促长组合。结果表明:3种高浓度植物生长调节剂(花盼、施奇或三十烷醇)对羊草具有极显著或显著的增产效果(P<0.01或P<0.05);中浓度叶面水溶肥(莱绿士)配合任何植物生长调节剂对羊草有极显著的增产效果(P<0.01);低浓度乐圃在配合有效植物生长调节剂的情况下对羊草有显著的增产效果(P<0.05);而渗透助剂则对羊草产量无显著影响(P>0.05)。说明7.5 mL/亩花盼水溶液,75 mL/亩施奇水溶液或37.5 mL/亩三十烷醇水溶液+150 g/亩莱绿士+75 mL/亩乐圃为天水地区栽培羊草促长增产的最佳肥调组合。
The research focused on plant growth regulator and fertilizer effect on Leymus chinensis L. yiled. By combining multiple plant growth regulators with fertilizer, mineral oil and additives, we design five orthogonal experiments which makes the following results: three kinds of regulators, i.e Huapan, Shiqi and Triacontanol under high concentration has significant or extreme significant stimulation effect on Leymus chinensis L. yield(P<0.01 or P<0.05);medium concentration fertilizer Lailiishi cooperating with any plant growth regulators has extreme significant stimulation effect on Leymus chinensis L. yield(P<0.01);low concentration Lepu cooperating with effective plant growth regulators has significant simulation effect on Leymus chinensis L. yield(P<0.05). The best conditions for Leymus chinensis L. yield sti mulation are Huapan 7.5 mL/mu, Shiqi 75 mL/mu or Triacontanol 37.5 mL/mu, Lailvshi 150 g/mu and Lepu 75 mL/mu.
