Ginkgo fertilization method

Ginkgo fertilization method

Spring leaf fertilizer

For young trees and adult fruit-bearing trees in an off-year, the best time to apply fertilizer is one month before Grain Rain, which is beneficial to increasing the fruit set rate. For mature trees, applying fertilizer about 15 days after Grain Rain can appropriately reduce the amount of fruit. Fertilization is mainly quick-acting fertilizer, supplemented by organic fertilizer.

Apply fruit-growing fertilizer in summer

Apply in early July, earlier rather than later. This period is the time when the fruits grow, the root system grows vigorously, and the flower buds differentiate. Whether nutrients can be supplied in time is crucial. Quick-acting fertilizer is the best for fruit-growing. Half a kilogram of urea can be sprayed on each tree. It must be added with water and the concentration should be controlled at around 0.1%. Generally, it is not suitable for application in furrows. If there is continuous drought after fertilization, water should be applied appropriately.

Apply body-nourishing fertilizer in autumn

Applying fertilizer after ginkgo seeds are harvested can make up for the nutrients consumed by fruiting and help the tree recover. Fertilizer utilization and absorption is higher when applied before peak root growth. It is best to choose farmyard manure as body fertilizer, and it is better to apply it in furrows.

Apply basal fertilizer heavily in winter

Around the Spring Festival, dig deep trenches and reapply base fertilizer. The base fertilizer mainly includes soil fertilizer, cake fertilizer, etc. For ginkgo trees that have been fertilized with enough body fertilizer, less or no base fertilizer can be applied.

Ginkgo fertilization precautions

Determine the reasonable amount of fertilizer and control the fertilizer concentration according to the growth conditions of ginkgo. Apply underground fertilizer at the right time during the growing season.

The best time to apply foliar fertilizer is in the evening because the absorption and utilization rate of the roots is high at this time. In addition, it is best to do it after it rains.

To assist with foliar fertilization, fertilizer can generally be sprayed on the leaves 6 times throughout the year.
