Abstract

The invention discloses a method for rapid propagation of jerusalem artichoke. The method comprises the following steps of 1, variety selection; 2, tuber treatment; 3, dormancy breaking; 4, planting of jerusalem artichoke; 5, water and fertilizer management. Healthy jerusalem artichoke tubers are selected and treated for 1.5 hours at the low-temperature condition of -20 DEG C; the jerusalem artichoke tubers are slowly unfrozen for 24 hours at 4 DEG C and then soaked for 10 min by using a 10% gibberellin solution, so that dormancy of the jerusalem artichoke tubers is broken. According to the method for rapid propagation of jerusalem artichoke, a low-temperature treatment technical means is used, so that the formation time of the jerusalem artichoke tubers is greatly shortened, it takes 3 months from seeding to tuber formation, and the growth time is saved by 40%; the jerusalem artichoke obtained after low-temperature treatment is not influenced by flowering, overground parts of the tubers are lower than 50 cm, the formed tubers can grow normally after dormancy is broken, and the tubers have vitality. The jerusalem artichoke can also normally grow in a greenhouse in winter to form the tubers, and a good foundation is laid for rapid propagation, processing and utilization of the jerusalem artichoke in the future.

Description

technical field [0001] The invention relates to the technical field of Jerusalem artichoke planting, in particular to a method for rapid propagation of Jerusalem artichoke. Background technique [0002] Jerusalem artichoke, also known as Jerusalem artichoke, ghost ginger, is a perennial herb. 1-3m high, with massive underground stems and fibrous roots. Jerusalem artichoke is a perennial herbaceous plant. Generally, it takes more than 5 months from sowing to tuber formation. Normal growing Jerusalem artichoke plants can only form tubers after flowering. The growth cycle is long, which restricts industrial production. Therefore it is very necessary to design a method for rapid propagation of Jerusalem artichoke. Contents of the invention [0003] The object of the present invention is to provide a kind of method for rapid propagation of Jerusalem artichoke, to solve the problem proposed in the above-mentioned background technology. [0004] In order to solve the above-men...
