A fast-growing and breeding method of Huazhonglouzi rhizome seedlings without destroying the original environment

Abstract

The invention relates to the technical field of huazhonglou seedling propagation, in particular to a method for fast-growing rhizome seedlings of huazhonglouzi without destroying the original environment. The method of the present invention includes: (1) selecting and planting more than 4 years of healthy and pest-free Huachonglou plants; (2) cutting off the rhizome terminal buds and all the above-ground parts; (3) removing the rhizomes left in the soil or the bare ground Cut the cut surface of the rhizome; (4) Disinfect the cut and dry it; (5) Dip the root of the Huazhonglou rhizome with the cut with GGR amino acid solution, spray boron fertilizer aqueous solution at the same time, dry it, and cover it with humus ; (6) Field management of the rhizomes of Huachonglou covered with humus soil; (7) In the autumn of the second year, many strong seedlings of sub-rhizomes have grown on the mother rhizomes of Huachonglou; (8) Picking (9) Disinfect the seedlings of the sub-rhizome, dry and then transplant; (10) Harvest after four years of cultivation. The invention has fast seedling emergence and high survival rate, solves the problem that seedlings are not easy to obtain in the large-scale planting of Huazhonglou, and has important production value and application value.

Description

technical field [0001] The invention relates to the technical field of huazhonglou seedling propagation, in particular to a method for fast-growing rhizome seedlings of huazhonglouzi without destroying the original environment. Background technique [0002] Hua Chong Lou Paris polyphylla Smith var. chinensis (Franch.) Hara. is one of the most representative and globally influential medicinal plant resources that occupy a leading position in industrial utilization in western medicinal plants. However, the plant resources are seriously depleted, and the use of cell engineering technology to produce secondary metabolites to alleviate the contradiction between supply and demand of plant resources has not yet been realized, and tissue culture and propagation of plant seedlings have not yet obtained satisfactory results. In terms of artificial cultivation and propagation, a certain number of companies and individuals have started the artificial planting of Huachonglou and start...

However, the seeds have dormancy characteristics. It will take 2 winters for the seeds to germinate when they are directly sown, and the germination rate is less than 50%. Seedbed cultivation, even if the seeds that were knotted in the current year are propagated by breaking dormancy, can only be shortened by one year. annual germination cycle

Although this invention improves the seedling rate and reproduction coefficient, this invention is the fast-growing reproduction of Huazhonglou under the condition of destroying the original environment, and the survival rate of seedlings cannot reach the ideal level, and the operation is complicated
