坐果率是形成产量的重要因素,而落花落果是造成产量低的重要原因之一。造成落花落果的原因有:贮藏养分不足,花芽质最差;授粉受精不良。各地银杏园引起落花落果的原因较为复杂,因此,必须具体分析实际情况,抓住主要原因,制定相应措施,才能有效地提高坐果率,其途径主要包括以下几方面。 Fruit set rate is an important factor in yield formation, and falling is one of the important reasons for low yield. The reasons for the drop: the lack of storage of nutrients, flower buds the worst; poor pollination and fertilization. The reason why the ginkgo garden in the local area is causing the fall and blossom is rather complicated. Therefore, we must analyze the actual situation in detail, seize the main reasons, and formulate corresponding measures to effectively improve the fruit setting rate. The main approaches include the following aspects.
