[0025] 1) Seed selection: select perennial, robust, non-injured, free from diseases and insect pests and fresh weight more than 80g Rhizome of Polygonum yunnanensis, cleaned, as a source of breeding;
[0026] 2) Cutting the tuber: take the rhizome of Prunus edulis, cut it at the part with terminal buds at a node length of 3-4 cm in the direction perpendicular to the main axis of the rhizome, cut it into irregular small pieces, and set aside;
[0027] 3) Incision treatment: Soak the cut irregular small pieces with terminal buds in the growth promoter, pick them up, dip them in plant ash or quicklime on the wound, and set aside;
[0028] 4) Seedbed establishment: Select an area with an altitude of 2000-2200m and an annual precipitation of more than 900mm, which is suitable for the growth of Dianzhong. The pit width is 6-9cm, the depth is 5-7cm, the planting...

Abstract
The invention discloses an asexual reproduction method of Yunnan paris polyphylla. The method includes the steps of seed selection; tuber cutting; notch treatment, namely soaking small irregular tubers cut with terminal buds into a growth promoter, and dipping dredged cut parts into plant ash or quick lime for standby use; seedbed establishment; tuber cultivation; field management including shed establishment, tillage and weeding, irrigation and drainage water, top application and ridging; pest control, namely preventing and controlling plant diseases and insect pests of root rot, leaf blight,cutworm, grub, scarab and black spot; transplanting cultivation, namely digging stems between October of the year and February of the following year and cutting germinal buds with sharp knives for transplanting. With the method, survival rate and sprouting percentage in asexual reproduction of the Yunnan paris polyphylla can be effectively increased, large-scale promotion is achieved, planting efficiency of the Yunnan paris polyphylla is effectively improved, and meanwhile, the method is simple in operation, and convenience in use is effectively improved.
Description
technical field [0001] The invention relates to the technical field of planting medicinal materials, in particular to a method for asexual reproduction of Rhizoma Dianchi. Background technique [0002] Dianzhonglou is a shade-loving plant. It should be planted in loose, fertile, well-drained, convenient irrigation, high organic matter content, more humus, and flat terrain. After selecting the planting site, it is necessary to clean up the land, carefully remove residues and impurities, and burn them with fire to reduce or prevent the occurrence of diseases and insect pests in the next year. Apply fully decomposed farmyard manure 30~45t / hm before soil preparation 2 , Deep turn 30cm. About 150kg / hm of quicklime can be sprinkled on excessively acidic soil 2 adjust. Make a furrow according to the slope direction of the plot, with a width of 1.2m and a height of 25cm, and furrows and ditches with a width of 30cm. Because Dianchrysanthemum polyphylla avoids direct sunlight, a...
