几种叶面喷施处理对灵武长枣生长的影响

Effect of different foliage application treatments on growth of Lingwu Long Jujube

采用植物生长调节剂碧护(0.05‰、0.1‰、0.15‰)、叶面肥魔粒丰(2%、4%)及赤霉素(GA30μg/kg)对灵武长枣进行叶面喷施处理,测定灵武长枣的枣吊长度与直径、叶面积与干质量、叶绿素等指标,分析叶面喷施处理对灵武长枣生长的影响.结果表明:以上喷施处理对灵武长枣的枣吊直径、叶片数、叶面积、叶干质量、比叶重的影响不显著,但喷施碧护0.05‰和碧护0.1‰处理的叶片厚度比对照分别高50%和25%,喷施2%的魔粒丰可显著提高叶绿素含量.

Using plant growth regulator Bihu（0.05‰,0.1‰,0.15‰）,foliage fertilizer Molifeng（2%,4%）,and GA（30μg/kg） to treat Zizyphus jujube Mill.cv.Lingwuchangzao,and testing the length of fruit shoot,leaf number in fruit shoot,leaf thickness,single leaf area,leaf chlorophyll content etc.,we studied the effect of different foliage application treatments on growth of lingwu long jujube.The result showed that the fruit shoot diameter,leaf number in fruit shoot,single leaf area,single leaf dry weight and specific leaf weight of different treatments were no significance differences,but the leaf thickness were increased by 1.5 times and 1.25 times when treated by 0.05‰Bihu and 0.1‰Bihu respectively,and the leaf chlorophyll contents was increased when treated by 2%Molifeng.
