Problems solved by technology

Since the newly harvested seeds are not treated effectively or planted immediately, the seed vitality will be easily lost. Therefore, in production practice, only the method of storing Sanqi in the sand at room temperature can prolong the seed vitality for 60-90 days, but this method cannot prevent Embryo Morphological Development Process

Embodiment 1

[0039] The method for the storage of embodiment 1, Panax notoginseng seed

[0040] 1) Acquisition of seeds: Collect 3-year-old healthy plants. When the fruits are ripe, they are harvested in batches, and the pedicels are removed together. The flower discs and immature fruits are removed. The mature fruits are scrubbed in clean water, and the exocarp is removed to obtain seeds. After washing with clean water, disinfect with 0.1% sodium hypochlorite (NaClO) aqueous solution for 10 minutes, and then wash with clean water repeatedly.

[0041] 2) Seed drying: dry in the shade at 20°C and 40% relative humidity for 24 hours to obtain seeds with a moisture content of 55%.

[0042] 3) Low-temperature and humidity-controlled storage: mix the seeds treated in step 2) with dry perlite at a volume ratio of 1:1, put them into a tissue culture bottle (that is, an open container), and then place the tissue culture bottle Put it into an airtight container with water at the bottom, use an empt...

Embodiment 2

[0049] Implement the method for the storage of 2, Panax notoginseng seeds

[0050] Identical with method in the embodiment of the present invention 1; Difference is:

[0051] The refrigerated storage time in step 3) is 270, wherein during the refrigerated storage, the seeds are ventilated and turned every other month, and the seeds are ventilated and turned 9 times in total;

[0052] The time of refrigerated storage in step 4) is 90 days, wherein during the storage, the seeds are ventilated and turned every other week, and the seeds are ventilated and turned 12 times in total.

[0053] The total storage time of the method of the present invention is the seeds after 360 days, and the seeds that break dormancy after storage are detected according to the greenhouse pot plant simulation in Example 1 of the present invention, and the germination rate is 54.67%; Emergence detection was carried out in pot simulation, and the emergence rate was 48%, as shown in Table 1.

Abstract

The invention discloses a method for moisture-controlling and dry storage of Panax notoginseng seeds. It comprises the following steps: 1) seed treatment: collect the mature fruit of Panax notoginseng, rub the peel in water to obtain mature and plump seeds, wash them with clean water after disinfection; 2) dry the seeds: dry the seeds obtained in step 1) Dry in the shade; 3) mix the seeds processed in step 2) with dry perlite, pack in open containers, and then place the open containers in airtight containers to control humidity and refrigerate, wherein the bottom of the airtight containers add Water, the said open container is not contacted with said water with a spacer; 4) the seeds treated in step 3) are mixed with moistened perlite, and then refrigerated. The invention uses a sealed container capable of controlling a certain environmental humidity to control humidity and refrigerate the seeds, which can prolong the morphological development time of the seed embryos; and prolong the time for the seeds to break dormancy after the germination of the seed embryos, which is convenient for transportation and storage, and is beneficial to improve the quality of the seeds. Germination rate and emergence rate after planting.

Description

technical field [0001] The invention relates to a method for moisture-controlled dry storage of Panax notoginseng seeds, which belongs to the field of traditional Chinese medicine storage. Background technique [0002] Panax notoginseng is a perennial herb of Araliaceae ginseng, also known as Jinbuhuan, blood ginseng, Tianqi, etc. Its roots, stems, leaves, and flowers can be used as medicine. It is a traditional Chinese medicinal material with warm nature and sweet and slightly bitter taste. , has the effects of hemostasis, blood stasis, swelling and pain relief, and is the main raw material of Chinese patent medicines such as "Yunnan Baiyao", "Compound Danshen Tablets" and "Compound Danshen Dripping Pills". Modern pharmacological research shows that Panax notoginseng contains 51 kinds of notoginseng saponins, 77 kinds of volatile oils represented by β-elemene, 17 kinds of amino acids represented by notoginseng, and various activities such as notoginseng polysaccharides and ...
