Description

Technical Field

[0001] The invention relates to the technical field of plant cultivation, and in particular to a cultivation method for shortening the dormancy period of cypress branches. Background Art

[0002] The sparse-flowered cyperus belongs to the Tamarix family. It was discovered and named by the Wuhan Institute of Botany, Chinese Academy of Sciences in the Three Gorges area in 1984. There are very few wild sparse-flowered cyperus, and the Chinese Academy of Sciences has determined it to be an extremely endangered species, known as the "giant panda of the plant world."

[0003] The growth habit of the sparse-flowered water cypress is different from that of ordinary plants. In the production cycle of a whole year, the wild sparse-flowered water cypress is in an environment below the water surface for 4-6 months. When the sparse-flowered water cypress is in an environment below the water surface, it mainly survives in a dormant state. When the water level drops in winter and the sparse-flowered water cypress emerges from the water, its dormant period ends and it enters the growth period.

[0004] In order to protect the diversity of plants, research units in the Three Gorges Reservoir area have conducted many studies on the artificial cultivation methods of sparse-flowered water cypress. The sparse-flowered water cypress was transferred from the water-side growth environment of the dam area to land cultivation. According to research, sparse-flowered water cypress has a good effect of drought resistance and sand fixation, but after it is transferred to land cultivation, it still has a dormant period of 50-70 days. In order to further improve the economic benefits of sparse-flowered water cypress, how to shorten the dormant period and extend the growth period is a technical problem that needs to be solved in this field. Summary of the invention
