枣树喷施赤霉素安全使用技术研究

The Technology of Safe Use Applying Gibberellin to Ju Jube Tree

目前枣树管理中普遍喷施赤霉素,虽然喷施赤霉素能显著提高枣果产量,但喷施高浓度的赤霉素对枣果的品质、风味和产量都会产生不利影响,经过5 a的不同浓度和不同频次的赤霉素喷施对枣果的影响试验,建议赤霉素的安全使用浓度为10 mg/kg,两次喷施间隔时间15 d。

At present in Chinese jujube management generally spraying GA3, although spraying GA3 can significantly improve the yield of jujube fruit, but spraying high concentration of gibberellin on jujube fruit quality, flavor and production will produce adverse effect.The experiment was carried out in five years of different concentrations and different frequency of gibberellin, suggest that the safe usage of gibberellin concentration of 10 mg/kg, it is recommended to use 15 d at intervals.
