摘要
通过采用不同方法进行核桃座果率的试验,结果表明:花期喷磷酸氢铵和磷酸二氢钾、在萌芽期去除90%雄花芽,或在伸长期去除60%和90%雄花,可明显提高核桃的座果率,从而提高核桃的产量。
Comprehensive measures can significantly increase the fruit-setting rate up to 82%.Application of NH4H2PO4 during blossoming period or deleting 90%of male flower buds during germination period,or deleting 60%of female flower buds during germination period can increase fruit—setting rate significantly.Spray of nitrogen and phosphors can also increase the fruit setting rate of walnut.
