In order to verify the optimal planting season of Ginkgo biloba, the author has done some tests: the same age Ginkgo biloba seedlings in the same nursery are transplanted in the same plot in autumn and spring season, and the planting methods and management measures are also completely. the same. The results showed that the trees planted in the fall of last year were basically normal in the following spring, and their growth was similar to that of trees transplanted in early years. After one year, they entered the normal growth period. The transplanted saplings were first germinated slowly, and some trees did not germinate until July or even the next year. That is, if the early seedlings sprouted, the growth was very slow. The branches that were smoked were only one or twenty centimeters. Obviously, autumn and winter are more suitable for planting ginkgo trees. This is because Ginkgo biloba is so susceptible to long seedlings. In addition to its physiological properties, an important reason is that it is difficult to heal the damage to its roots, and autumn and winter leaves have fallen, and sap no longer flows. Stop growing, of course, no longer consume large amounts of nutrients, so the workload of tree roots has been greatly reduced. In such circumstances, the roots of the injured tree, which has been injured during the growing season, will recuperate for a period of time and the wound will heal quickly, normally absorbing and accumulating nutrients, entering the second peak of development in the year, and the tree after the spring of the following year. The body is fully prepared for germination and growth. This shows that the profound significance of planting ginkgo trees in autumn and winter is that it has been effective for several months ahead of a long period of slow seedling growth, especially for transplanting Ginkgo biloba seedlings. Shorten the effect of one year. As for the specific dates for planting ginkgo trees in autumn and winter, local areas can be flexibly controlled according to the local climate conditions. It is better to transplant the leaves before they are frozen in the ground. China Agricultural Network Editor
