New technique for storage, grafting and fast propagation of seed buds of Populus euramericana cv.Quanhong

Abstract

The invention provides a new technique for storage, grafting and fast propagation of seed buds of populus euramericana cv.Quanhong. The method comprises the step: storage of seed buds: when seedlings of populus euramericana cv.Quanhong are transplanted, collecting broken-off, stumped and pruned seed shoots and tree branches into bundles; humidifying, packaging, labeling and storing the seed shoots and the tree branches into a refrigerating chamber for future use in May to June. The propagation speed is accelerated, the propagation material is saved and the purpose of quick promotion is achieved; and the new technique has the features of fast propagation speed, good effect and high benefit.

Description

technical field

[0001] The invention relates to the field of plant grafting and planting, in particular to a high-speed expansion and propagation technology for whole red poplar seed bud storage grafting. Background technique

[0002] At present, Quanhong poplar is a new colorful poplar variety newly selected and bred in my country. Due to a series of characteristic advantages, lack of provenance, rapid breeding, and the high cost of cuttings and low survival rate of cutting seedlings, many introducers introduce The success rate is not high, further exacerbating the lack of provenance.

[0003] Therefore, the present invention is developed on the basis of mainly solving the above deficiencies in the prior art. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for accelerating the breeding speed and saving the breeding materials.

[0005] Based on above-mentioned purpose, the technical problem solved in th...
