specific Embodiment approach 1

[0018] Specific embodiment one: the method for high-efficiency seedling cultivation of Shuisu seeds in this embodiment is implemented according to the following steps:

[0019] 1. Seed collection and pretreatment: According to the phenological characteristics of Shuisu, the mature seeds (dark brown seeds) of Shuisu were collected several times between late July and late August. After removing impurities and shriveled seeds, the The seeds are placed in a cool and dry place to air-dry to obtain air-dried seeds;

[0020] 2. Nutritional soil configuration: According to the characteristics of the wild habitat of Shuisu and the demand for nutrients, the peat soil and vermiculite are fully mixed and configured according to the volume ratio of 1:1 to obtain the nutritional matrix;

[0021] 3. Seed disinfection: soak the air-dried seeds obtained in step 1 in distilled water to obtain soaked seeds, and then transfer them to an ethanol solution with a volume percentage of 70% to 75% for ...

specific Embodiment approach 2

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the rachis of the inflorescence is not destroyed each time the stachys seed is collected, and the immature seeds above the inflorescence are kept to continue to mature.

specific Embodiment approach 3

[0028] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 1, the mature seeds of Shui Shui Shui are collected twice between late July and late August.

Abstract

The invention relates to an efficient breeding method of nectariferous plant Stachys baicalensis seeds and aims to solve the technical problems that current Stachys baicalensis area is reduced greatly, the work for converting farmland to wetlands is short of industrial and technical support, and the Stachys baicalensis seed breeding technology is in shortage. The breeding method includes the stepsof firstly, collecting manure Stachys baicalensis seeds, and performing air drying in a dry plate; secondly, sufficiently mixing peat soil and vermiculite according to the proportion of 1:1 to obtaina nutrition medium; thirdly, impregnating the dried seeds into distilled water, and then transferring into an ethanol solution for impregnation; fourthly, impregnating the sterilized seeds in warm water of 30-60 DEG C; fifthly, sowing into culture cups; sixthly, placing water into the culture cups to perform culture; seventhly, performing final-period management. The method has the advantages that by the variable-temperature germination accelerating method, seedling emergence time is shortened, and breeding success rate is increased greatly ; hormones or pesticides are not used in the breeding process, the method is capable of saving cost, ecological, environmentally friendly and suitable for large-scale greenhouse breeding, and the cultured seedlings are robust.

Description

technical field [0001] The invention relates to a method for raising seedlings of the nectar source plant Shuisu. Background technique [0002] The project of returning farmland to wetland can gradually restore the integrity, nature and diversity of the wetland ecosystem and improve its fragile ecological environment. It is one of the specific measures to restore the damaged wetland and ensure that the existing wetland will not be degraded. However, it is necessary to consider both natural ecological factors and the current social and economic conditions for returning farmland to wetlands. Reasonable alternative livelihoods also affect the smooth implementation of the policy of returning farmland to wetlands. At present, my country still lacks good models and technologies for returning farmland to wetlands, which restricts the development of the work of returning farmland to wetlands. [0003] Stachys baicalensis belongs to the genus Stachys of Labiatae, and it is produced ...
