Embodiment Construction

[0025] The Daqing area of ​​Heilongjiang Province belongs to the alpine and high latitude area, and there are no precedents and mature techniques for planting ginkgo trees. In the process of introducing ginkgo trees, the applicant, after four years of exploration and experience accumulation, summed up the process of selecting, transplanting, and cultivating. Then to domestication, until the method and technology of survival, the specific steps of introduction are:

[0026] 1. Screening tree species:

[0027] The ginkgo trees in Dandong area are of good type, good growth, and healthy plants, and the lowest temperature in winter in this area is generally about minus 15 degrees Celsius, which is relatively smaller than that in Daqing area. As long as the trees are kept warm, they should be able to survive. The applicant chose One ginkgo tree each with DBH 8cm, 9cm, and 10cm.

[0028] 2. Selection of planting site:

[0029] The quality of the tree planting site determines the su...
