几种药剂对山杏工林产量影响的研究.pdf

摘 要 本文以乌兰察布市卓资县上高台林场坝底营林区的人工山杏林为研究对象 ，喷 施不同浓度的不同药剂进行处理，以喷施清水做对照 （ck），对各种处理下的山杏 不同生长时期的物候、百叶重、鲜果重、干果重、一年生枝条进行调查和对比分析， 结果表明： 1.B9 和硼酸溶液都具有预防山杏早春低温天气危害提高山杏花芽成花率的作 用。B9 是一种生长延迟剂，具有推迟花期的作用，1500ppm、1000ppm 和 500ppm 三 种浓度分别推迟花期 4d、3d 和 2d。1500ppm 的处理相对于 ck 的成花率和坐果率有 明显的作用。硼酸具有提高山杏花芽抗性的作用，1500ppm 浓度的硼酸对提高山杏 的成花率明显提高。通过对两种药剂各 3 种浓度与 ck 的比较，喷施 1500ppm 浓度 的药剂的山杏的成花率和坐果率都有显著的提高。 2.防落素、稀土和多效唑主要是在山杏幼果期进行喷施 。防落素具有推迟果柄 断层形成时间，增加果柄硬度，防落素 25ppm 处理的山杏，单株结果数最多。稀土 具有增加幼果发育的作用，稀土 1000ppm 和 1500ppm 处理的山杏单果重最大，多效 唑属于生长延缓剂，能够有效的抑制一年生枝条的生长，多效唑 2000ppm 处理的山 杏一年生枝条相对 ck 减少了 17.8cm。 关键词：山杏人工林；生长调节剂；丰产技术 Following Several Medicaments of Artificial Mountain Apricot Forest Influence Studies Yield Abstract In this paper ZhuoZiXian wulanchabu city under forest in the camp stronghold of artificial mountain forest dam as the research object, following spraying different concentrations of different elixir processing, with spraying water (ck) were compared, the Artificial mountain of various processing with different growth periods of phenology, shutter heavy, fruit weight, dried fruit weight, annual survey and analysis branch, the results show that: 1. B9 and boric acid has Artificial mountain early spring the cold weather hazard prevention Artificial mountain bud much increase the role. B9 is a growth delay agent, has postponed flowering role, 1500ppm, 1000ppm and 500ppm three concentrations were postponed flowering 4 days, three days and a 2 days. 1500ppm processing relative to ChengHua ck ratio and fruit-bearing rate has obvious effect. Artificial mountain bud resistance of boric acid is raising the role of 1500ppm concentration, to
