Alternate cooling and heating paris polyphylla seed propagation method

Abstract

The invention relates to an alternate cooling and heating paris polyphylla seed propagation method, which comprises the three major steps including seedbed selection and processing, seed selection and seed processing, and seeding, wherein a concrete seed selection and seed processing method comprises the steps that full and ripe paris polyphylla seeds with the thousand seed weight being 40 to 70g and without disease, mildew or damage are selected, and the seeds are soaked for 10 minutes by 30PPM GA for 10 minutes before the germination acceleration; then, the seeds are mixed with clean fine sand according to a mixture ratio of 2:1, episperm is removed through rubbing, and the seeds are cleanly cleaned and are soaked for 1 hours by 500 times of carbendazim; the processed seeds are buried into the wet sand to be processed for 2 months at 5 to 10 DEG C, are then placed to an 18-20-DEG C environment to be processed for 3 months, are next placed into a 5-10-DEG C environment to be processed for 1.5 months, and are then placed into a 20-22-DEG C environment to be processed for 1.5 months, and the attention is paid on the moisture preservation in the period. When the method provided by the invention is adopted, the germination period of the paris polyphylla seeds can be reduced from two years into one year, in addition, the germination rate of the paris polyphylla seeds is effectively improved, and the germination rate reaches more than 90 percent.

Description

Technical field [0001] The present invention is a plant cultivation technology field, which involves a method of breeding the seeds of the Dian heavy building. Background technique [0002] The Dianzhonglou, known as a unicorn, is a perennial herb.The rhizomes are stout, the stem height is 20-2500px, hairless, often purple -red, and the base has 1 to 3 membrane leaf sheath hug.5 to 11 leaves, green, round, 7-425px long, 2.2 to 150px width, is a long ovary and round or lanceolate, apex sharp or gradual, the base wedge -shaped to round, full,It is often a pair of obvious base veins, and the petiole is 0-50px.The top of the flower was born in the center of the impeller, the gender, the flowers stretched out, the flowers were extended, and the flowers were two rounds., Yellow -green, the upper part is often expanded to a narrow spare shape with a width of 2-5mm.The stamens are 2 to 4 rounds, 8-12 pieces, the flower medicine is 5-10mm long, and the medicine is obvious, and the length ...

Problems solved by technology

[0005] At present, the wild Parisia diarrhea is becoming increasingly depleted, and the market is mainly met by artificial planting; however, the seeds of Parisia diarrhea have obvious post-ripening effects, and the seed embryos need to be dormant and ripen before they can germinate, that is, they can only be unearthed after two winters under natural conditions. Seedlings with a low emergence rate
