【摘要】 2013-2014年用7种叶面剂(肥)进行了骏枣保花保果田间试验,结果表明,4%赤霉酸乳油、75%赤霉酸结晶粉、0.01%芸苔素内酯乳油对骏枣枣吊坐果率和单株产量的提高有明显效果,与对照比较均可提高39%和68%以上;其次是0.1%噻苯隆可溶性液剂,与对照相比,可使骏枣枣吊坐果率和单株产量分别提高27%和65%;其他叶面剂(肥)效果稍低,但与对照比较,也可提高11%和22%以上。更多还原

【Abstract】 The test of increasing set of fruit by using seven kinds of foliar fertilizer was did during 2013-2014 on Junzao.The result showed that foliar fertilizer could produce high fruit setting rate and yield per tree.The setting rate of shedding shoot of jujube could increase 39% and yield per tree could increase 4% using emulsifiable concentrate of gibberellic acid,75% crystal powder of gibberellic acid and 0.01%emulsifiable concentrate of emulsifiable concentrate comparing without using it.The setting rate of shedding shoot of jujube could increase 27% and yield per tree could increase 65% using thidiazuron soluble liquid comparing without using it.The setting rate of shedding shoot of jujube could increase 11% and yield per tree could increase 22% using other foliar fertilizers comparing without using it.更多还原
