Detailed Explanation of Ginkgo Cultivation Techniques, Master All Key Planting and Management Points

The ginkgo tree is a tree with extremely high ornamental value. It produces many flowers in April and a large number of fruits in October, making it very beautiful. At present, it is planted in many green areas, so what are the ginkgo cultivation techniques?

1. Site selection: Ginkgo likes light, so a sunny slope with a gentle gradient should be selected as the afforestation site. It has no strict requirements for soil conditions, but neutral or slightly acidic soil with a thick upper layer, moist and fertile soil, and good drainage is best.

2. Reasonable arrangement of pollinator trees: Select plants with strong terminal buds, plump and full lateral buds, and no pests or diseases, then select some male plants with the same variety and flowering period as the female plants. The ratio of female to male plants is 25-50:1. The arrangement method adopts a 5-plant or 7-plant square-center pattern, or four-corner arrangement.

3. Reasonable close planting: In the early stage, a spacing of 2.5×3 m or 3×3.5 m between plants and rows is generally used, with 88 or 63 plants planted per mu. After the rows close, transplanting is carried out. First, every other row is moved from the plant spacing, becoming a 5×3 m or 6×3 m plant-row spacing, with 44 or 31 plants per mu. After a few years, every other row is again transplanted from the original row spacing, becoming a 5×6 m or 6×7 m plant-row spacing, with 22 or 16 plants planted per mu.

4. Planting time: Ginkgo is mainly planted in autumn with leaves and in spring before leafing. Autumn planting is carried out from October to November, which allows the seedling root system a longer recovery period and prepares for the aboveground sprouting in the second spring. When planting before spring sprouting, because the aboveground part sprouts quickly and the root system does not have enough time to recover, growth is not as good as with autumn planting.

5. Planting method: After the hole is dug, backfill the topsoil and apply fermented fertilizer containing superphosphate. When planting, spread the seedling root system naturally, align it with the seedlings in front, behind, left, and right, then fill in topsoil while firming it. The planting depth should be such that the soil is mounded to 2~3 cm above the original soil mark on the seedling; do not bury the seedling too deeply. After planting, water thoroughly with settling water in time to improve the survival rate.
