Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seed storage, and more particularly to a seed storage method for improving the germination potential of Lumnitzeralittore seeds. BACKGROUND

[0002] Lumnitzeralittore is a rare mangrove plant of the family Combretaceae and the genus Lumnitzera, and is a national first-class key protected plant. It is also rarely distributed in other countries and regions, and is only sporadically distributed in India, Sri Lanka, Myanmar, Thailand, Indonesia and Malaysia in Southeast Asia. In China, it is naturally distributed in Xincun Port and Tielu Port in Lingshui and Sanya, with 3 plants in Lingshui and 9 plants in Sanya, which is the most serious endangered true mangrove plant in China. The extremely low seed germination rate is the main factor leading to the endangerment of Lumnitzeralittore, and even if there is occasional germination, the survival rate of seedlings in the natural habitat is also low.

[0003] Currently, the seeds are usually collected and sown immediately. Since the flowering period of Lumnitzeralittore is from March to June, and the fruiting period is from June to October, if the seeds are collected and sown immediately after maturation, the seed germination time is long, and the seeds begin to germinate 2 months after sowing, and the seeds have not completely germinated until June of the next year, with a seed germination period of more than 8 months, a germination rate of about 10%, and a very uneven germination potential, which increases the difficulty of seedling cultivation and management, wastes manpower, and increases the cost of seedling cultivation. SUMMARY

[0004] The purpose of the present application is to provide a seed storage method for improving the germination potential of Lumnitzeralittore seeds, which improves the seed germination potential by selecting a favorable sowing time for sowing after the seed storage stage, and cultivating Lumnitzeralittore seedlings.

[0005] The above technical purpose of the present application is achieved by the following technical scheme: a seed storage method for improving the germination potential of Lumnitzeralittore seeds, comprising the following steps:

[0006] S1: collecting Lumnitzeralittore fruits and washing and soaking them in water for 15-20 days, with water changed every 5-7 days;

[0007] S2: removing the fruit skin from the Lumnitzeralittore fruits soaked for 15-20 days by rubbing them multiple times to obtain the kernel fruits;

[0008] S3: washing the peeled kernel fruits in clean water, taking them out, placing them in a gauze bag, and placing them in a cool place for 1-2 days to obtain Lumnitzeralittore seeds for seedling cultivation;

[0009] S4: Prepare the cultivation pot, 2 cultivation pots as a group, stacked, put a small hole with a diameter of 5cm in the upper cultivation pot, and block the hole of the cultivation pot with a pvc pipe wrapped with multiple layers of film; Place the prepared cultivation pot in a cool and humid place and cover it with plastic film;

[0010] S5: Lay 5cm thick coconut husk or loose loam soil on the bottom of the drilled cultivation pot, and then spread the treated red apricot seeds on the coconut husk or loam soil, with a seed thickness of ≤3cm;

[0011] S6: Prepare a certain proportion of salt water, immerse the red apricot seeds in the prepared salt water for 2-3 hours every day, then loosen the pvc pipe inserted in the cultivation pot, and let the water slowly leak into the lower cultivation pot; the next day, insert the pvc pipe tightly and then pour the water in the lower cultivation pot into the upper cultivation pot to immerse the red apricot seeds;

[0012] S7: Measure the salinity of the water body immersing the red apricot seeds every day, when the water body salinity is higher than 35‰, supplement clean tap water to adjust the salinity to 30‰; the prepared salt water is discarded after 1 month of use, and new salt water is prepared for immersing the red apricot seeds;

[0013] S8: After the storage period of the red apricot seeds is over, take them out, wash them with clean tap water, and then sow them.

[0014] The application further provides that in step S4, the cultivation pot is a plastic pot or a foam pot, and the length, width and height of the pot are 40cm, 30cm and 20cm respectively.

[0015] The application further provides that in step S6, the coarse sea salt and tap water are prepared in a proportion of 31:1000 to prepare salt water with a concentration of 30‰.

[0016] In summary, the application has the following beneficial effects: through the storage method for improving the germination potential of red apricot seeds provided in the application, the seed germination potential is improved through seed storage, the seed germination rate is improved, and the seedling growth is good after transplanting the seedlings.

[0027] S6: prepare a 30‰ salt water by mixing coarse sea salt and tap water at a ratio of 31:1000, immerse the Prunus armeniaca seeds in the prepared salt water for 2-3 hours every day, then loosen the pvc pipe inserted in the cultivation pot to allow water to slowly leak into the lower cultivation pot, and the next day, insert the pvc pipe tightly and pour the water in the lower cultivation pot into the upper cultivation pot to immerse the Prunus armeniaca seeds;

[0028] S7: measure the salinity of the water body for immersing the Prunus armeniaca seeds every day, and when the salinity is higher than 35‰, supplement clean tap water to adjust the salinity to 30‰; after the prepared salt water is used for 1 month, it is discarded and new salt water is prepared for immersing the Prunus armeniaca seeds;

[0029] S8: take out the Prunus armeniaca seeds after the storage period ends, wash them with clean tap water, and then sow them.

[0030] Red olive plums were harvested from a red olive orchard and soaked for 15-20 days. The drupes were then rubbed and peeled, and divided into four groups of 1,000 each. The four groups were placed in foam basins with a seed thickness of 3 cm. Two foam basins were stacked together. A small hole with a diameter of 5 cm was drilled in the upper foam basin. The hole was sealed with a similarly sized PVC tube wrapped with multiple layers of film. The prepared foam basins were placed in a cool, humid area and covered with plastic film. The length, width, and height of the foam basins were 40 cm, 30 cm, and 20 cm, respectively. The basins were immersed in saline solution with concentrations of 25‰, 30‰, 35‰, and 40‰ for 2 hours daily, followed by a slow release of the water. Six months later, the seeds were removed and sown, then incubated in 5‰ saline. They began to germinate 10 days after sowing and were nearly complete after one month. The number of seeds that germinated was 107, 116, 106, and 85, respectively, with germination rates of 10.7%, 11.6%, 10.6%, and 8.5%, respectively. The highest germination rate was achieved in seeds submerged in 30‰ saline.

[0031] 9,000 red plum fruits were collected from a red plum forest and, after soaking, rubbing, and peeling using the aforementioned method, placed in foam basins with a seed thickness of 3 cm. The basins were submerged in 30‰ saline for 2 hours daily. After 7 months, the seeds were removed and sown and incubated in 5‰ saline. Eight days after sowing, the seeds began to germinate. One month later, 1,021 seeds had germinated, for a germination rate of 11.3%. The seedlings were later transplanted into nutrient bags, where they are growing well.

After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
