1. Reasons for psychological consequences: 1. Poor nutrients and nutrient loss. In the era of fruit drop, new shoots continued to develop, and nutrition was consumed for the development of new shoots, forming a fruit drop. Flower bud differentiation is incomplete, causing late fruit drop. 2, poor pollination. Potted ginkgo must be equipped with pollination trees, otherwise the fruit can not be developed, and the fruit in the late stage is serious. In the flowering period, if the rain and rain stretch, affecting the pollination, it is easy to drop fruit. 3. The structure of the tree is unfair. The tree is tall, the branches are too dense, and the wind is not well transmitted. It affects the accumulation of inorganic nutrients in the branches, and the branches develop weakly. The fruits on the branches are easily scattered. 4. Lack of fertilizer and water. The soil is boring for a long time, the soil is thin, the fertilizer and water are difficult to receive, and the fruit is formed. When the soil moisture is too much, the root can be reduced. Even if more fertilizer is applied, the tree body is difficult to receive and use, and the fruit supply will be deficient. 5. Rainfall impact. The late fruit drop of Ginkgo is related to rainfall, and the rainfall is mostly fruitful. This is due to the lack of sunshine in the formation of rain, and the weakening of mutual light assistance, which has caused the fruit of a department in the unlucky part of the nutrient to fail to obtain full nutrition. 2, due to the formation of pests and diseases 1. Ginkgo biloba insect damage. Also known as the tree shrew, the damage to the ginkgo tree is very heavy, often forming a serious fruit drop. 2. The worm is seriously injured. The worm is a kind of beneficial insect that specifically damages ginkgo fruit. It is usually in the summer and early autumn, and the fruit is soft and soft. 3, anthrax injury. As usual, the amount of illness occurred in September, causing fruit drop. Disclaimer: Some articles on this website are transferred from the Internet.
