摘要
对"灵武长枣"花期采用喷施赤霉素(20 ppm)、三六氨基酸叶肥(400倍液)、硼砂(0.5%)+蔗糖(0.5%)、硼砂(0.5%)+食用红糖(0.5%)进行处理,测定‘灵武长枣’坐果率、叶绿素、有机酸、Vc、可溶性糖和可溶性固形物等的含量,研究外源药剂处理对‘灵武长枣’的果实及坐果率与果实品质的影响,结果表明:喷施赤霉素(20 ppm)、三六氨基酸叶肥(400倍液),坐果率分别是对照的4倍和3.1倍,叶绿素含量是对照的4.6和2.4倍,喷施硼砂(0.5%)+食用红糖(0.5%)可显著提高可溶性固形物含量.生产中可在花期喷赤霉素(20 ppm)或三六氨基酸叶肥(400倍液),或者硼砂(0.5%)+食用红糖(0.5%),以提高灵武长枣的坐果率,改善品质.
Spraying Gibberellin（20 PPM）, 3-6-amino acid leaf fertilizer（400 times liquid）, borax（0.5%） ＋sucrose（0.5%）, borax（0.5%） ＋edible brown sugar（0.5%） in flowering of Lingwu long jujube, determining the fruit setting rate, chlorophyll, organic acid,Vc, soluble sugar and soluble solids content. This paper studied the effects of exogenous chemicals on the fruit, fruit setting rate and fruit quality of Lingwu long jujube. The results showed that the fruit setting rate was 4 times and 3.1 times higher than that of the control respectively after spraying Gibberellin（20 PPM） and 3-6-amino acid leaf fertilizer（400 times liquid）.The chlorophyll content was 4.6 and 2.4 times higher than that of the control. Spraying borax（0.5%） ＋edible brown sugar（0.5%） can significantly increase the content of soluble solids. In production, spraying Gibberellin（20 PPM） or 3-6-amino acid leaf fertilizer（400 times liquid）,or borax（0.5%） ＋edible brown sugar（0.5%） can be used in flowering in order to increase the fruit setting rate and improve the quality of Lingwu long jujube.
