Seedling raising and planting method for Paris polyphylla Var. yunnanensis

Abstract

The invention discloses a seedling raising and planting method for Paris polyphylla Var. yunnanensis, and relates to the technical fields of cultivation and planting of traditional Chinese medicines.The seedling raising method comprises the following steps: selecting seeds, selecting mature seeds of the Paris polyphylla Var. yunnanensis, and performing natural drying until red seed coats lose water and are wilted; performing shelling cultivation: using cotton to dip ethanol to scrub the surfaces of the seeds of capsules of the Paris polyphylla Var. yunnanensis subjected to low-temperature treatment, stripping outer shells of the capsules, putting the seeds of the Paris polyphylla Var. yunnanensis of which the outer shells are stripped into water, performing scrubbing to remove arils, andperforming airing until no water exist for standby application; performing seed dressing on the seeds subjected to coat-removing treatment by using gibberellin, and placing the obtained seeds for 5-7days; and uniformly sprinkling the seeds of the Paris polyphylla Var. yunnanensis subjected to seed dressing by using the gibberellin on a seedbed prepared from mixed nutrient soil, performing seedling raising, and after seedlings emerge, performing foliar fertilization. According to the method provided by the invention, the gibberellin is adopted for seed dressing, so that the post-ripening timeof the seeds is shortened, the seedling emergence cultivation cycle of the seeds is accelerated, and the survival rate of the seeds is improved; and the planting method provided by the invention is easy to promote, has a high income and a lower risk, and lays a good foundation for a large range of artificial planting of the Paris polyphylla Var. yunnanensis.

Description

technical field [0001] The invention relates to a seedling raising and planting method of Chonglou dianthus, belonging to the technical field of traditional Chinese medicine cultivation and planting. Background technique [0002] Dianzhonglou, also known as unicorn lotus, is a perennial herb. The rhizomes are thick, 20-2500px high, glabrous, often purple-red, with 1-3 membranous leaf sheaths covering the stem at the base. 5-11 leaves, green, whorled, 7-425px long, 2.2-150px wide, obovate-oblong or oblanceolate, apex acute or acuminate, base cuneate to round, entire, It often has a pair of obvious basal veins, and the petiole is 0-50px long. Flower terminal in the center of the leaf wheel, bisexual, pedicel elongated, perianth in two whorls, outer tepals 4-6, green, ovate or lanceolate, inner and outer tepals the same number, linear or filamentous , yellow-green, the upper part often expands into a narrow spatulate 2-5mm wide. Stamens 2-4 rounds, 8-12 pieces, anthers 5-10...

AI Technical Summary

Problems solved by technology

Under natural conditions, it takes 2 winters, about 18-22 months, for the germination of the seeds of Dianzhonglou, and the emergence rate is relatively low, and the seedling rate is even lower, less than 1%.

Due to the limitation of resources and environment, few people have studied the reasons for the low germination rate and poor seedling growth rate of P.
