Problems solved by technology

[0002] Jerusalem artichoke is a perennial herb with a height of 1-3 meters. It has massive underground stems and fibrous roots. Jerusalem artichoke tubers enter dormancy after harvesting. In scientific research and small-scale production, the method of soaking gibberellin to break dormancy is used for research. Or production, but generally Jerusalem artichoke tubers need 10-15 days from breaking dormancy to germination, and the time interval is long, which will inevitably affect scientific research and agricultural progress. method is necessary

Abstract

The invention discloses a method for rapidly promoting germination of jerusalem artichoke tubers after dormancy breaking. The method includes the steps: first, tuber dicing; second, gibberellin soaking; third, mixed solution preparation; fourth, soaking culture treatment; fifth, greenhouse culture. The jerusalem artichoke tubers with bud eyes and without damage or rot are selected, washed out withclean water and then placed at a dry sunshade position to dry surface moisture in the air, the dried jerusalem artichoke tubers are cut into pieces, each piece has a single bud eye, the jerusalem artichoke tubers are longitudinally diced from heads to umbilical regions, each small tuber is cut into two pieces, each medium tuber is cut into four pieces, and each large tuber is longitudinally cut into two large pieces and then diced from the bud eye in the umbilical region. A certain quantity of gibberellin solution is weighed, a small amount of alcohol is added to perform dissolution, and thendistilled water is added to dilute the solution to needed concentration. The germination time of the jerusalem artichoke tubers is greatly shortened, growth vigor at a seedling stage is good, and emergence rate is high.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for rapidly promoting germination of Jerusalem artichoke tubers after breaking dormancy. Background technique [0002] Jerusalem artichoke is a perennial herb with a height of 1-3 meters. It has massive underground stems and fibrous roots.
