摘要
红枣作用农村产业结构调整和实施退耕还林的重要经济树种之一,分布面积广。多年来,如何提高其经济效益,不断进行探讨和研究,经过多次试验,实践证明,对红枣叶面喷施适当浓度的稀土微肥,对红枣的结果密度、座果率和产量均有明显的提高。这一试验成果极具推广应用价值。
The distribution of Chinese date was widespread.The Chinese date tree was one of important economic trees that adjusted countryside industrial structure and carried out the policy of changing farmland into woods.To improve its economical benefit continuous investigations and experiments were made.As a result the density of fruit,fruit set percentage and the yield were increased by spraying the proper concentration rare earths on Chinese date leaves which had important value for popularizing and applying.
