What to Do When Ginkgo Trees Drop Their Fruit? Cause Analysis and Treatment Methods
The ginkgo tree is a tall tree of the ginkgo family. The seeds of the ginkgo tree are commonly known as ginkgo nuts (baiguo), a green health food with high economic value. So, what should you do when a ginkgo tree drops its fruit?Come and learn with the editor!
1. Fertilizing
When the ginkgo tree blooms and young fruit appears, it should be top-dressed at least twice: the first top-dressing during the fruit enlargement stage, and the second during the kernel growth stage. During the fruit enlargement stage, apply phosphorus fertilizer and other trace element fertilizers to promote fruit growth and development; during the kernel growth stage, apply a mixed fertilizer of urea and phosphorus fertilizer. Decide the amount based on the tree's growth and fruiting conditions to increase the nutrient accumulation in the tree, improve the tree's resistance, and reduce fruit drop.
2. Water
Ginkgo trees like neither excessive water nor drought. In dry weather such as summer, water promptly, because drought will hinder the enlargement of ginkgo fruit, prevent yields from increasing, and also worsen fruit drop, affecting flower bud differentiation the following year. If continuous rainy weather occurs and water accumulates severely in the orchard without timely drainage, the waterlogging will prevent the roots from breathing and lead to insufficient nutrient uptake, causing the parts closest to the ground to begin dropping leaves and fruit. Therefore, when growing ginkgo, do a good job of orchard drainage and irrigation in a timely manner to improve the fruit set rate of ginkgo.
3. Pruning
When the ginkgo tree reaches the flowering stage, it needs a large amount of light and nutrients. If the tree does not receive sufficient sunlight and water, the fruit will grow poorly, the fruit stalk will begin to turn yellow, and the fruit will start to drop. Therefore, during cultivation, properly prune the water sprouts, overly dense branches, and overlapping branches in the tree. However, be careful to wrap the wounds after pruning to prevent the loss of water and nutrients through the wounds. This will enhance the permeability within the tree, strengthen nutrient accumulation in the fruit tree, and thereby reduce fruit drop.
4. Fruit thinning
The ginkgo tree differs from other fruit trees in that its growth alternates between on-years and off-years. In an on-year, the number of fruit on the tree increases, easily exceeding what the branches can bear. If fruit is not thinned in time, the branches may break under the weight; moreover, too much fruit increases the demand for nutrients, causing nutrients to be transported entirely to the fruit, leaving the branches and leaves with insufficient nutrition, and this will also make the on-year and off-year pattern more severe. Therefore, do a good job of fruit thinning during the young fruit stage to prevent fruit drop caused by excessive fruit later on.
