Breeding method of rhizoma polygonati seeds

Abstract

The scheme discloses a breeding method of rhizoma polygonati seeds, belonging to the technical field of breeding of rhizoma polygonati. The breeding method comprises the following steps: A, drying the rhizoma polygonati seeds until the water content is 8 to 10 percent, and refrigerating at the temperature of 1 to 3DEG C; B, 20 to 25 days before the seeds are sown, adjusting the refrigeration temperature of the seeds to 15 to 20DEG C and covering the seeds with 4 to 5 layers of gauze which is soaked into water and wet through; C, 2 to 3 days before the rhizoma polygonati seeds are sown, taking out the rhizoma polygonati seeds and soaking the rhizoma polygonati seeds with warm water with the temperature of 30 to 35DEG C for 35 to 40 hours; D, soaking the rhizoma polygonati seeds with a mixed solution consisting of brassinolide and gibberellin for 6 to 8 hours; E, sowing the rhizoma polygonati seeds on a substrate with the thickness of 3 to 5cm, and then spreading the substrate with the thickness of 2 to 3cm on the rhizoma polygonati seeds, and then watering through the substrate on the upper and lower layers of the rhizoma polygonati seeds with clear water, wherein the substrate is formed by uniformly mixing vermiculite, river sand and distillers' grains; F, after the rhizoma polygonati seeds are sown, keeping the moisture of the substrate at 35 to 40 percent, performing fertilizing and deinsectization in time. The rhizoma polygonati seeds are bred by adopting the method in the scheme, so the germination rate of the rhizoma polygonati seeds can be significantly improved.

Description

technical field [0001] The invention relates to the technical field of Polygonatum reproduction, in particular to a method for breeding Polygonatum. Background technique [0002] Polygonatum is also known as tiger ginger, chicken feet ginseng and so on. It is a plant of Liliaceae and Polygonatum, the rhizome is horizontal, cylindrical, and the nodules are enlarged. Leaves whorl, sessile. Medicinal plants have the functions of invigorating the spleen, moistening the lungs and promoting body fluid. In my country, Polygonatum is one of the commonly used medicines in traditional Chinese medicine. The medicinal history of Polygonatum has exceeded 2,000 years. It is recorded in the Chinese medical classics "Shenxian Zhicao Jing" and "Compendium of Materia Medica": "Huangjing broadens the middle and nourishes Qi, makes the five internal organs good, the muscles are full, the bone marrow is strong, and it will not age for many years. It will turn white and black, and the teeth wi...

Problems solved by technology

This kind of seed breeding method, in the sand storage process, although the dormancy of the sealwort seeds will be ended in advance, but a large amount of nutrients of the sealwort seeds will be consumed in the sand storage process, which is not conducive to the germination of the seeds when the seeds are sown; The lack of refined breeding management makes the germination rate of seeds only about 60%
