Embodiment 1

[0036] A kind of pinellia flood and drought staged seed propagation method, comprises the following steps:

[0037] (1) Seed collection and processing

[0038] In June, pick the immature pinellia seeds together with the inflorescence stalks in advance (the upper part of the spathe is withered, and the color of the seeds changes from green to white or slightly yellow) ( figure 1 ), put it in a mesh bag and put it in a cool and ventilated place for 2 days for use;

[0039] (2) Substrate treatment for seedling cultivation (substrate preparation)

[0040] Utilize dregs and perlite to mix according to the volume ratio of 3:1 to obtain the seedling-raising substrate, use the 1500-fold dilution of the deltamethrin emulsion and the 3000-fold dilution of the active ingredient content 30% hymexazol to the seedling-raising substrate Disinfect and reserve after 10 days;

[0041] (3) Cultivation substrate preparation: mix loam: medicine dregs (money herb dregs): perlite according to the...

Abstract

The invention discloses a segmented seed breeding method for pinellia chinensis flood and drought. By adopting floating trays for seedling cultivation and rationally adjusting the ratio of medicinal residue and perlite, the water content of the substrate can be precisely controlled to meet the higher water requirements for the germination of Pinellia pinellia seeds. , to ensure the smooth germination of pinellia seeds; the fermented dregs are rich in nutrients, providing sufficient nutrients for the early germination of pinellia. In the stage of dry-type seedling cultivation, the mixed matrix of loam, traditional Chinese medicine residue and perlite is used to domesticate Pinellia seedlings intensively to cultivate strong seedlings and reduce the incidence of seedlings. Moreover, the method of the invention can increase the germination rate of pinellia to more than 90%, reduce field management costs, facilitate the large-scale production of pinellia seedlings, and provide sufficient high-quality seed sources for pinellia planting.

Description

technical field [0001] The invention relates to the field of planting Chinese herbal medicines, in particular to a segmented seed breeding method for pinellia pinellia in flood and drought. Background technique [0002] Pinellia (Latin name), also known as Sanbutiao, Mayuguo, Yanziwei, etc., is a perennial herb of the family Pinellia. Its dry tuber is one of the commonly used Chinese medicinal materials, which has the functions of drying dampness and resolving phlegm, reducing adverse flow and relieving vomiting. According to different processing methods, it can be divided into pinellia, pinellia clear, pinellia ginger, pinellia fasciana, and mainly treats symptoms such as phlegm retention and vomiting, damp phlegm cough, qi reversal, chest tightness, and dizziness. [0003] Pinellia has three propagation methods: tubers, bulbils and seeds. Under field conditions, tubers and bulbils are the main propagation methods. After long-term excavation, the provenance of wild pinell...
