以色列叶面肥和赤霉素对同心圆枣坐果率及产量的影响

Effects of the Israel Foliar Fertilizer and GA_3 on Fruit-set and Yield of 'Tongxinyuanzao'

通过对同一栽培管理条件下的同心圆枣树喷施沃盾以色列叶面肥和赤霉素,探讨沃盾以色列叶面肥和赤霉素对枣树坐果率及产量的影响。结果表明：不同处理叶面肥＋赤霉素组合在一定程度上提高了坐果率及产量,而枣树坐果率和产量随着叶面肥喷施浓度增加而呈现下降的趋势;处理1~4的单株产量较对照分别提高了1.65 kg、2.76 kg、3.30 kg、1.46kg。综合试验结果,在生产上可使用1 100倍沃盾以色列叶面肥＋赤霉素来提高枣树产量。

The same management practiced ＇Tongxinyuanzao＇ jujube trees were sprayed by foliar fertilizer, GA_3 and water in comparison. The effects of the ＇Wo dun＇ Israeli foliar fertilizer and GA_3 on fruit-set and yield of ＇Tongxinyuanzao＇ were discussed. The results indicated that the foliar fertilizers and GA_3 of different treatments could improve fruit-set and yield to a certain extent, and jujube fruit fruit-set and yield showed a downward trend with increasing concentration of foliar fertilizers,which was spraying. In terms of yield of individual, compared with the control of water spraying, the yield of treatment 1~4were increased by 1.65 kg, 2.76 kg, 3.30 kg, 1.46 kg, respectively. In conclusion, the 1 100 times ＇Wo dun＇ Israeli foliar fertilizer＋ GA_3 was used to improve yield of jujube tree in production.
