Humulus lupulus fast replication method

Abstract

The invention relates to a fast propagation method for hops, which is characterized in that, annul stem collected from hop plant is used as the propagation mother branch; then single node shoot is cut to perform cutting vegetative propagation; the method is completed according to following steps: propagation mother branch is collected, and one-year shoot of the plant is used as the propagation mother branch; pruning and cutting are carried out to the mother branch; the mother branch is dipped in quick dip rooting medium, and the cutting wood is quickly dipped in the rooting medium before cutting; ridges are made in a solar greenhouse, and sand is arranged on the ridges; a shading net with the shading rate ranging from 80% to 90% is used for shading; humidity, temperature and ventilation are maintained in the greenhouse; cutting seedlings can safely pass winter. The fast propagation method for hops has the advantages that, a large amount of seed braches are saved; yield is not influenced; reproductive output is increased; reproductive speed is accelerated; the quick dip rooting medium suitable for hop single node shoot cutting is adopted, and the rooting rate of hop shoot cutting can reach more than 95%; cutting survival rate ranges from 90% to 95%.

Description

technical field [0001] The invention relates to hop propagation technology, in particular to a method for rapid propagation of hops. Background technique [0002] Hops, scientific name Humulus lupulus L. Moraceae, is a perennial herbaceous plant and is one of the main raw material crops in the beer brewing industry. Hops are known as "the soul of beer". [0003] The traditional method of hop propagation is: collecting perennial stems from hop plants as reproductive mother bars, and then cutting double-node or multi-node stem segments for asexual propagation by cuttings. This method, due to the need to use a large number of perennial mother bars with production capacity, will easily cause a great impact on the yield, and in the case of a large number of seedlings, the propagation speed is slow and the production volume is small, which often cannot meet the production needs. At present, most of the hop varieties used in my country's production are "Qingdao Dahua" which began ...
