Propagation method of Pterocarya stenoptera var. zhijiangensis

Abstract

A propagation method of Pterocarya stenoptera var. zhijiangensis includes artificial propagation steps of seed bed preparation, cutting collection, cuttage, post-cuttage management and the like. Vegetative seedling raising can be successfully performed to Pterocarya stenoptera var. zhijiangensis by the method, the rare species, Pterocarya stenoptera zhijiangensis, is continued, the survival rate of Pterocarya stenoptera zhijiangensis is more than 95%, and field seedlings grow neat with consistent properties.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a plant breeding method. Background technique [0002] Pterocarya stenoptera C.DC.Var. Zhijiangensis Z. E. Chao et C. J. Zheng. [0003] More than 30 years ago, on the stump of a century-old common poplar tree in Zhijiang, a seedling with leaves, trunks and materials different from ordinary poplar trees grew. According to fellow forestry experts, this tree was discovered in 1979 by Yan Xiaogui, the former director of the Zhijiang County Forestry Institute. On May 18, 1979, a technician from the County Forestry Institute cut off branches and leaves from the "strange tree" and compared them with ordinary poplars. Opposite, the leaves of this tree are solitary; the second is that the bark of general poplar is chapped, but the bark of this tree is smoother; the third is that the material of general poplar is white, and the material of this tree is red; It is warped, but the seeds and fru...

Problems solved by technology

[0005] At present, in the process of experimenting with the multi-seed breeding method of Populus chinensis, the "seed breeding method" was first used, but it was found that the seeds of this species were asexual species. The second is to adopt the "mold grafting breeding method" test, which also has no chance of success due to natural wind damage; the third is to adopt the "branch breeding method" test, because the mother of this species cannot be divided in this method. Resulting in unsuccessful breeding; the fourth is to use the "grafting breeding method" test, due to the weirdness of this species, resulting in extremely poor affinity and failure to report
