Embodiment 1

[0018] A method for improving the germination rate of Polygonatum rhizome without buds, comprising the following steps:

[0019] 1. Obtain no-bud rhizome nodes.

[0020] 2. Dehydration: Lay the no-bud rhizome nodes on the ventilated and cool ground to dehydrate them by 30%. During the dehydration process, the ambient temperature is 25°C, and the no-bud rhizome nodes cannot be piled up, and the thickness of the tiles should not exceed 15cm. Turn over every 2 days. The dehydration time depends on the environmental conditions. Generally, the dehydration time lasts for about 1 week.

[0021] 3. Low-temperature storage: Lay the dehydrated non-bud rhizome nodes in an orderly manner in a frame filled with moist fine sand. The water content of the fine sand is 8%. During the tiling process of the rhizomes, there are 1cm interval. Move the frame with bud rhizome nodes to a refrigerated warehouse with a temperature of 3°C for dark storage. During the storage period, check the situatio...

Embodiment 2

[0025] A method for improving the germination rate of Polygonatum rhizome without buds, comprising the following steps:

[0026] 1. Obtain bud-free rhizome nodes

[0027] 1.1 Excavation of rhizomes: After autumn, the above-ground part of Polygonatum japonicus is gradually withered. Before frost, the rhizomes of Polygonatum japonicus are excavated to avoid damage to the rhizomes of Polygonatum japonicus, and try to keep the fibrous roots on the rhizomes intact.

[0028] 1.2 Seed selection: Select rhizomes with complete appearance, no pests and diseases, and excellent appearance from the excavated rhizomes of Polygonatum rhizomes to use as propagating rhizomes.

[0029] 1.3 Segmentation: Segment the selected Polygonatum Rhizome, cut off the rhizome nodes with bud heads and store them separately, and segment the remaining rhizomes with a knife to obtain no-bud rhizome nodes, each with 3 no-bud rhizome nodes , the length of each no-bud rhizome node is 5cm, and the mixture of plan...

Abstract

The invention discloses a method for accelerating germination, and particularly relates to a method for increasing the germination rates of bud-free rhizomes of rhizoma polygonati. The method for increasing the germination rates of the bud-free rhizomes of the rhizoma polygonati includes steps of bud-free rhizome node acquisition, dehydration, low-temperature storage and germination accelerating.The water loss of the of bud-free rhizome nodes can reach 25%-30% at the step of dehydration. The method has the advantages that the bud ratios of the bud-free rhizomes of the rhizoma polygonati can be greatly increased by the aid of the method in the following year after the bud-free rhizomes of the rhizoma polygonati are dug, and obvious effects can be realized.

Description

technical field [0001] The invention relates to a method for accelerating germination, in particular to a method for increasing the germination rate of Polygonatum rhizome without buds. Background technique [0002] Polygonatum is a plant of the genus Polygonatum in the family Liliaceae. The rhizome is enlarged in segments and sweet in taste. It has the functions of nourishing the spleen, moistening the lungs and promoting body fluid. At present, sealwort on the market mainly comes from the excavation of wild populations. In recent years, some planting enterprises have begun to artificially breed and plant sealwort. The provenance mainly comes from the domestication of wild species, but there are still many technical problems unsolved in the process of planting and propagation. The artificial breeding of Rhizoma Polygonatum is mainly propagated to the next generation through seeds and rhizomes. Seed breeding has always had a low emergence rate due to technical means. In cont...
