Ginkgo biloba cuttage is divided into two kinds, one is hardwood cuttage, one is softwood cuttage.Hardwood cuttings are generally carried out in spring, which are usually cut in late autumn and early winter, preserved outdoors after treatment, usually mixed in sand, and then taken out in spring.Softwood cuttings should be carried out in July, warm climate is more conducive to its rooting, too cold easy to frostbite it.
The cuttings of hardwood cuttings are generally selected from the current year branches of young trees. If it is a big tree, the current year branches in the middle and lower parts should be used. If the branches are too old or too thick, it is not conducive to rooting.Generally, it should be cut into 25-30 cm long, tied together with 50 roots, and soaked in rooting powder solution at the bottom.Shoots should be semi-lignified branches of the year, with 2-3 buds on them, and the bottom should also be soaked in rooting water.
Before cutting, it is necessary to prepare a substrate, usually sandy soil as a seedbed, which is conducive to the growth of new roots.Disinfect the soil before use to avoid cutting infection.Insert the cuttings into the soil to a depth of one third or one half.If large-scale cuttings are used, the row spacing of 25 cm and the plant spacing of 15 cm should be maintained.
After the completion of cutting, attention should be paid to shading, especially for twig cutting, because of the strong light in July, water evaporation is very fast without shading, which is not conducive to its rooting.In addition, keep the air moist, so as to reduce the loss of water, until it takes root, you can transplant it to other places, when transplanting roots with soil balls.
