Method for reducing sleeping cycle of Paris polyphylla seeds

Abstract

The invention discloses a method for reducing a sleeping cycle of Paris polyphylla seeds; the method comprises the following operation steps: collecting mature Paris polyphylla seeds; removing skins of the Paris polyphylla seeds; naturally drying the Paris polyphylla seeds for 20 days at 15-25 DEG C; after mixing the Paris polyphylla seeds and soil with water content of 30-40% according to a ratio of 1:3, putting the seeds and the soil in a refrigerator; gradually reducing the temperature of the refrigerator from 20 DEG C at a speed of 4 DEG C per day until the temperature reaches 0 DEG C; placing the seeds and the soil in the refrigerator for 30 days; gradually increasing the temperature of the refrigerator to 20 DEG C; taking out the seeds and the soil and placing the seeds and the soil at 15-25 DEG C for 30 days; repeating the operation again; taking out the Paris polyphylla seeds; and then planting the seeds on a seedling raising bed; covering 2 cm-thick soil on the seedling raising bed; and thoroughly watering the seedling raising bed, so that the seeds are germinated in the soil after 50 days. Through the adoption of the method, the seedling emergence period of the Paris polyphylla seeds is reduced and the germinating rate of the Paris polyphylla seeds is increased.

Description

Technical field [0001] The invention relates to a planting method, in particular to a method for shortening the dormancy period of the seeds of Chonglou. Background technique [0002] Chonglou (Latin name: Paris polyphylla Smith var, chinensis (Franch) Hara) is a commonly used Chinese medicinal material, which has the effects of clearing heat and detoxification, reducing swelling and pain, cooling the liver and relieving convulsions. Wild Chonglou is depleted day by day, mainly relying on artificial planting to satisfy the market; however, Chonglou seeds have obvious post-ripening effect. The seed embryos need to mature after dormancy to germinate, that is, after two winters under natural conditions, seedlings can be unearthed, and The emergence rate is low. Summary of the invention [0003] In view of the shortcomings of the prior art, the present invention aims to provide a method for shortening the dormancy period of C. C. multiflorum seeds to ensure that the emergence period...

The wild chrysanthemum is becoming increasingly exhausted, and the market is mainly met by artificial planting; however, the seeds of chrysanthemum have obvious post-ripening effects, and the seed embryos need to be dormant to be ripe before they can germinate, that is, it takes two winters under natural conditions to emerge from the ground and become seedlings. low germination rate
