Problems solved by technology

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

Embodiment 1

[0032] From September to December of the first year, at the artificial planting base of Huazhonglou, healthy Huazhonglou plants with no diseases and insect pests for more than 4 years were selected and planted in patches (judging the age of Huazhonglou plants based on the stem marks of the rhizome residues). For Huazhonglou whose rhizomes are all buried in the ground, use a sterilized knife to cut off the top buds of the rhizome and the aboveground parts of the plants from the head of the rhizome of Huazhonglou; For some plants, the remaining rhizomes are always kept in the ground; cut the cutting surface of the rhizomes left in the soil, the number of cutting rounds is 1 round, and the number and size of the cuttings depend on the size of the cutting surface of the rhizomes; for some rhizomes exposed to the ground, Cut off the rhizome terminal buds and all the above-ground parts. The number of incision rounds is 3 rounds, and the distance between each round is preferably the i...

Embodiment 2

[0035] From September to December of the first year, at the artificial planting base of Huazhonglou, healthy Huazhonglou plants with no diseases and insect pests for more than 4 years were selected and planted in patches (judging the age of Huazhonglou plants based on the stem marks of the rhizome residues). For Huazhonglou whose rhizomes are all buried in the ground, use a sterilized knife to cut off the top buds of the rhizome and the aboveground parts of the plants from the head of the rhizome of Huazhonglou; For some plants, the remaining rhizomes are always kept in the ground; use a sterilized knife to cut the cut surface of the rhizomes left in the soil. The rhizome of the rhizome is cut off the top bud and all the above-ground parts of the rhizome. The number of incision rounds is 2 rounds, and the distance between each round is preferably the internode distance of Huazhonglou. The incision was disinfected with plant ash or 75% chlorothalonil wettable powder. Use the G...

The rhizome of the rhizome, cut off the top bud and all the above-ground parts of the rhizome, the number of incision rounds is 5 rounds, and the distance between each round is preferably the internode distance of Huazhonglou. The incision was disinfected with plant ash or 75% chlorothalonil wettable powder. Use the GGR...

Abstract

The invention relates to the technical field of paris-polyphylla-var-chinensis seedling propagation, in particular to an original-habitat-undamaged fast-growing propagation method for paris-polyphylla-var-chinensis child rhizome seedlings. The method includes the steps that (1) healthy and pest-disease-damage-free paris-polyphylla-var-chinensis plants planted for more than 4 years old are selected; (2) rhizome terminal buds and all aboveground parts are cut off; (3) rhizomes remaining in soil or rhizome sections exposed on the ground are cut; (4) the incisions are sterilized and aired; (5) the paris-polyphylla-var-chinensis rhizomes with the incisions are dipped with a GGR amino acid solution, a boric fertilizer aqueous solution is sprayed at the same time, and the obtained rhizomes are aired and covered with humus; (6) the paris-polyphylla-var-chinensis rhizomes covered with the humus are subjected to field management; (7) in the second autumn, multiple strong child rhizome seedlings grow on the paris-polyphylla-var-chinensis parent rhizomes; (8) the child rhizome seedlings are picked; (9) the child rhizome seedlings are sterilized, aired and transplanted; (10) harvesting is conducted after four-year planting. According to the original-habitat-undamaged fast-growing propagation method, seedling emerging is rapid, the survival rate is high, the problem that seedlings of paris-polyphylla-var-chinensis are difficult to obtain during large-scale planting is solved, and the important production value and the important application value are achieved.

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...
