Fertilization method of Ginkgo biloba

Apply long leaf fertilizer in spring

For young trees and adult fruit trees, the best fertilization time is one month before the grain rain, which is conducive to improving the fruit setting rate. For adult trees, fertilizing about 15 days after the valley rain can appropriately reduce the amount of fruit. Fertilization is mainly quick acting fertilizer, supplemented by organic fertilizer

Summer application of long fruit fertilizer

It should be implemented in the first ten days of July, sooner rather than later. This period is a period of fruit growth, vigorous root growth and flower bud differentiation. Can nutrients be supplied in time. Quick acting fertilizer is the best for long fruit fertilizer. Each tree can be poured with half a kilogram of urea. Water must be poured with the concentration controlled at about 0.1%. It should not be used in general. In case of continuous dry weather after fertilization, it shall be watered appropriately

Autumn body fertilizer

Fertilizing ginkgo seeds after harvest can make up for the nutrients consumed by fruit and is conducive to the recovery of tree potential. When applied before the peak of root growth, the utilization and absorption of fertilizer are higher. The best choice of body fertilizer is to apply farmyard fertilizer, and it is better to apply it in ditches

Heavy application of base fertilizer in winter

Before and after the Spring Festival, open deep ditches and apply base fertilizer again. The base fertilizer mainly selects soil miscellaneous fertilizer, cake fertilizer, etc. For ginkgo trees with sufficient nutrient fertilizer, less or no base fertilizer can be applied

Precautions for fertilization of Ginkgo biloba

According to the growth status of Ginkgo biloba, determine the reasonable fertilization amount and control the fertilization concentration. Underground topdressing shall be carried out in due time during the growth period

The best time for topdressing outside the root is in the evening, because the absorption and utilization rate of the root system is high at this time. In addition, it's best to do it after rain

Auxiliary foliar fertilization: generally, fertilizer can be sprayed on the foliar surface 6 times a year< span>
