Outdoor dormancy breaking rapid propagation seedling raising method for polygonatum sibiricum seeds and polygonatum sibiricum seedlings

Abstract

The invention discloses an outdoor dormancy breaking rapid propagation seedling raising method for polygonatum sibiricum seeds and polygonatum sibiricum seedlings. The method comprises the following steps: cleaning: thoroughly scrubbing polygonatum sibiricum seeds; disinfection: disinfecting the seeds with a disinfectant; coating: soaking the seeds in a gibberellin solution, adding the seeds into a fludioxonil suspending agent, and performing uniform stirring for coating; outdoor dormancy breaking: uniformly mixing the seeds with river sand, scattering the mixture into sandy soil at the altitude of 1200-1500 meters, laying a straw mat on a compartment surface, laying a sunshade net on the straw mat, taking out the seeds and the river sand together after breaking dormancy of the seeds, and uniformly spraying the gibberellin solution; and seedling raising: scattering the seeds into soil located at the altitude of 400-600 m, building a sunshelter and a greenhouse integrated greenhouse, and laying a layer of wood chips on matrix soil. According to the method, dormancy breaking is carried out on the polygonatum sibiricum seeds in the high-altitude and low-temperature environment, the dormancy period of the polygonatum sibiricum seeds can be shortened to one year from two years through the seedling raising method, the seedling raising period is effectively shortened, and various operating costs in the seedling raising process are reduced.

Description

technical field [0001] The invention relates to the technical field of dormancy-breaking of seeds, in particular to an outdoor dormancy-breaking and fast-growing seedling method of Polygonatum seeds and Polygonatum seedlings. Background technique [0002] Polygonatum, also known as: Chicken Head Polygonatum, Yellow Chicken Vegetable, Pen Tube Vegetable, Claw Ginseng, Tiger Ginger, Chicken Claw Ginseng. It is a plant of the genus 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. At present, sealwort is widely planted and developed because it is widely used in medicine and also as a food material. [0003] After the sealwort seeds are sown, it takes 2 years of dormancy to germinate and grow into sealwort seedlings. Since the dormancy period before germination of the sealwort seeds is too long, a lot of labor m...

Problems solved by technology

[0003] After the sealwort seeds are sown, it takes 2 years of dormancy to germinate and grow into sealwort seedlings. Since the dormancy period before germination of sealwort seeds is too long, a lot of labor maintenance costs and time costs are required

In the prior art, Polygonatum sowing adopts the method of indoor sowing, and the cost of the space occupied by indoor sowing is very high, and during the dormancy period of up to 2 years, it needs to continuously occupy the indoor space for germination, which brings excessive costs to the operator. economic pressure
