化学药剂组合处理对核桃坐果率的影响

Effect of Chemical Agent Combined Treatment on Fruit Setting Rate of Walnuts

以3个核桃品种"新丰"、"新光"、"新丰上10"为试材,在核桃盛花期分别喷施0.3%尿素+0.3%硼砂(处理Ⅰ)、10%蔗糖+0.02%硼酸(处理Ⅱ)、处理Ⅰ+处理Ⅱ混合溶液(处理Ⅲ),通过分析3种处理对3个核桃品种坐果率的影响,筛选出能提高核桃坐果率的最佳配比。结果表明:3种处理对3个核桃品种坐果率的影响有所差异,其中处理Ⅲ的坐果率最高,与对照相比,"新丰"、"新光"和"新丰上10"的坐果率分别提高为62%、17%、35%;其次是处理Ⅰ,3个核桃品种的坐果率分别提高为48%、7%、22%;处理Ⅱ的效益最低,坐果率分别提高为34%、0%、14%。3种处理相比,处理Ⅲ对核桃坐果率的提高效率最高,在核桃栽培生产上有一定的推广价值。

Three walnut varieties ＇Xinfeng＇,＇Xinguang＇ and ＇Xinfengshang 10＇ were used as plant materials,0.3% Urea＋0.3% borax（treatment Ⅰ）,10% sucrose＋0.02% boric acid（treatment Ⅱ）,treatment Ⅰ＋treatment Ⅱ mixed solution（treatment Ⅲ） were sprayed on those walnut varieties within fullbloom stage,the purpose was to screen out the best proportion solution which could enhance fruit setting rate of walnut by compared effect of three treatments on three walnut varieties in this paper.The results showed that,there were some difference on the effects of three treatments on the fruit setting rate of three walnut varieties,among them the treatment Ⅲ had best effect on fruit setting rate,to compared with control treatment fruit setting rate of ＇Xinfeng＇,＇Xinguang＇ and ＇Xinfengshang 10＇ were enhanced 62%,17%,35%,respectively;next was treatment Ⅰ,fruit setting rate of three walnut varieties were enhanced 48%,7%,22%,respectively;treatment Ⅲ had lowest effect,fruit setting rate of three walnut varieties were enhanced 34%,0%,14%,respectively.Three treatments compared each other,treatment Ⅲ had the best popularization value on walnut cultivation and production.
