What are the reasons why a ginkgo tree does not bear fruit?
The ginkgo tree is a very common tree species in our country, and its ornamental value is very high. It can be seen in many cities, and its fruit is also very popular. The fruit of the ginkgo tree is called white fruit (baiguo), and its nutritional value is very high, so many people plant it mainly for the fruit. However, sometimes the ginkgo tree does not bear fruit, so what are the main reasons? Let's take a look together below!
1. Reasons
1. Improper management
The main reason the ginkgo tree does not bear fruit is improper management of the underground part after planting. If the soil environment in which the ginkgo tree grows is relatively poor, and the soil is barren with a compacted condition, then the soil permeability will be too poor, causing the plant to grow weakly. After planting, it may fail to bear fruit for many years. At the same time, when fertilizing, if you apply too much nitrogen fertilizer and neglect the application of phosphorus and potassium fertilizers as well as trace elements, then the crown of the ginkgo tree will expand too quickly, and the leaves will be too thin and not deep in color, thereby affecting photosynthesis and causing the ginkgo tree not to bear fruit.
2. Improper grafting
If a ginkgo tree relies on itself to bear fruit naturally, the fruiting time is very long, and sometimes it may not bear fruit for more than ten years. Therefore, ginkgo trees are now generally grown mainly by grafting. However, when grafting, if the scion is taken from branches of a ginkgo tree that has never borne fruit or has just begun to bear fruit, then because the physiological development stage of the scion is too young, the crown will form too quickly after grafting, resulting in a long delay in fruiting after grafting.
2. Solutions
If we want to solve the problem of the ginkgo tree not bearing fruit, then we first need to carry out corresponding prevention and treatment according to the reasons why the ginkgo tree is not bearing fruit, and choose the corresponding solutions. First, for ginkgo trees that grow vigorously, around May each year, carry out girdling at the base of the main branches. The width of the girdling should be kept at about 1/10 of the girdled main branch. Then in May and June, spray wettable powder paclobutrazol once each time. And in May, sufficient high-quality compound fertilizer should also be applied as a top dressing to promote nutrient absorption by the ginkgo tree.
After the above measures have been taken, if the ginkgo tree produces a large number of female flowers the following year, then high-quality male flowers can be selected for pollination work. The pollination interval should be kept at about two days. For ginkgo trees that grow relatively weakly, water and fertilizer management should be done well. When fertilizing, phosphorus and potassium fertilizers should be the main ones, combined with an appropriate amount of nitrogen fertilizer. If dry weather occurs, then watering should be done well; similarly, during the rainy season, drainage should be timely to avoid waterlogging damage, and it is best to also do a good job in preventing and controlling diseases and pests such as leaf blight and stinging moths.
The above is a brief introduction to why the ginkgo tree does not bear fruit. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
