Paris polyphylla seedling raising and large-scale planting method

Abstract

The invention relates to the technical field of traditional Chinese medicinal material planting, in particular to a paris polyphylla seedling raising and large-scale planting method. The paris polyphylla seedling raising and large-scale planting method comprises the following steps: S1, seed selection and sand storage treatment: in the mature period of paris polyphylla seeds in autumn, selecting and harvesting the seeds which are full, free of plant diseases and insect pests and dark red in color, and taking out the seeds after sand storage treatment; S2, skin breaking treatment: performing ultrasonic skin breaking treatment on the seeds; S3, seed soaking and germination accelerating: soaking the seeds with a paris polyphylla seed soaking solution for 2-5 hours, and sowing the seeds after the seeds root; S4, sowing and seedling raising: respectively planting the rooting seeds into porous seedling raising trays filled with a sterile culture medium; S5, seedling stage management; S6, field management; and S7, harvesting: harvesting paris polyphylla tuber finished products after cultivation is performed for 3-5 years. Aiming at overcoming the defects in the prior art, the paris polyphylla seedling raising and large-scale planting method is provided and can increase the survival rate of paris polyphylla planting and shorten the seedling raising period.

Description

technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, in particular to a method for raising seedlings and large-scale planting of eucalyptus. Background technique [0002] Chonglou, also known as four unicorn lotus, seven-leaf one-branch flower, and Chonglou-one-branch arrow, belongs to Liliaceae and is a perennial herb. The medicinal part is the dry tuber of Chonglou, which is bitter in taste, slightly cold, slightly poisonous, and returns to the liver meridian. It has the effects of reducing heat and detoxification, reducing swelling and stopping bleeding, cooling the liver and relieving convulsions, etc. The medicinal polyphylla is mainly collected in the wild, and some are artificially introduced and cultivated. Due to excessive excavation, the reserves of wild resources have further shrunk, and the price has risen year after year. [0003] At present, the planting of Chonglou is mainly for seed germination and rhizome...

AI Technical Summary

Problems solved by technology

Planting rhizomes in sections will occupy a large amount of raw materials for production, which will intensify the contradiction between cultivated seeds and medical raw materials. In addition, the rhizomes after cutting are easy to be infected with mildew and rot due to the difficulty in controlling the moisture and temperature in the field, and the loss rate of germplasm materials is as high as 50%. % or more, the reproduction rate is low, the emergence is irregular, it is inconvenient to manage, and the planting cost is also high, which is not conducive to the large-scale promotion of the planting of double building

The seeds of Chonglou have the physiological characteristics of post-embryo ripening. Under natural conditions, it takes two winters to germinate, and the emergence rate is only about 20%. The reproductive coefficient is low and the seedling cultivation period is long.
