Description

Technical Field

[0001] This invention relates to the field of lichen cultivation technology, specifically a method for cultivating and increasing the yield of lichen. Background Technology

[0002] Nostoc commune, also known as earth ear, lichen, earth fungus, ground fungus, thunder fungus, ground soft fungus, and sweet potato skin, is a combination of fungi and algae. It typically grows in dark, damp places and is dark in color, somewhat resembling softened black fungus. Nostoc commune is rich in protein, various vitamins, and minerals such as phosphorus, zinc, and calcium. Scientists at the Weizmann Institute of Science in Israel have discovered that a component in nostoc commune can inhibit the activity of acetylcholinesterase in the human brain, thus potentially having a therapeutic effect on Alzheimer's disease. Nostoc commune is a delicacy, best suited for soups, offering a unique flavor. It can also be used in cold dishes or stews, and is considered a cooling food.

[0003] The thallus of *Gnaphalium affine* is firm and gelatinous, initially spherical, later expanding into a flattened form, several centimeters in diameter, often a perforated membranous or leathery substance. Sometimes it exhibits irregular curls, resembling wood ear mushrooms, and appears blue or olive in humid environments; after drying, the thallus turns yellowish-green or yellowish-brown.

[0004] Nostoc commune has a wide range of habitats and adapts very well to varying temperatures, from the frigid Antarctic to the scorching deserts, from snow-capped mountains above 5000 meters to areas traversed by volcanic lava flows. It is highly drought-tolerant and undemanding in terms of soil. It thrives even in places where grass struggles to grow, and even after decades of dormancy, it quickly recovers upon contact with water. Furthermore, Nostoc commune prefers calcium and is an indicator plant for calcium-rich soils. It grows abundantly in calcium-rich areas such as limestone karst regions and the loess plateau of northern China. It possesses considerable biomass in areas with high calcium content and low pollution, such as desert grasslands. Its reproductive method primarily involves heterocellular division of the algal filaments into several small segments called phycogenes, which easily break off from the heterocellular cells. Each phycogene then grows into a long filamentous body through cell division. This method of reproduction via phycogenes is also a form of vegetative propagation. It can fix nitrogen through heterocellular division. It is edible. It has been a common wild vegetable for thousands of years, growing mainly in calcium-rich environments such as karst regions and the loess plateau of northern China. It is remarkably resilient, able to withstand prolonged drought, high temperatures, cold, and high radiation through dormancy, and then quickly revitalize and reproduce upon the arrival of rain.

[0005] Nostoc commune is highly nutritious. As people's demand increases, the quality and quantity of naturally grown Nostoc commune can no longer meet the demand. Therefore, artificial cultivation and increased production are needed to meet people's demand for Nostoc commune. In response to the above problems, a cultivation and yield-increasing method for Nostoc commune is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a method for cultivating and increasing the yield of *Gnaphalium affine*, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-5 In this embodiment of the invention, a method for cultivating and increasing the yield of *Gnaphalium affine* includes the following steps:

[0035] Step 1: Breeding;

[0036] Step Two: Modify the planting land;

[0037] Step 3: Planting;

[0038] Step 4: Install the sunshade components;

[0039] Step 5: Regular Management;

[0040] Step Six: Harvest.

[0041] Step one involves screening wild lichen or the selected seeds for sterilization and cultivation, and then selecting superior lichen as the original species.

[0042] Step two involves manually weeding the planting land. The planting land is transformed from bottom to top into a slow-release layer 1, an isolation layer 2, and an attachment layer 3. A drainage ditch 4 is installed on the planting land for drainage. The planting land is selected from abandoned travertine areas that have been free of pollution for more than three years, thus realizing the utilization of wasteland. The drainage ditch 4 is conducive to the drainage of water accumulated in the planting land.

[0043] The slow-release layer 1 is composed of soil, fermented leaves, and decomposed sheep manure; the isolation layer 2 is a mesh or non-woven fabric; and the attachment layer 3 is a mixture of pebbles, sand, cobblestones, etc. There are two isolation layers.

[0044] Step three involves dividing the original seed cultivated in step one into 3cm long segments and planting the diced lichen into small pits dug in the attachment layer.

[0045] The shading component in step four includes a support frame 6, which is straddling the planting area in parallel. Both ends of the support frame 6 are inserted into and fixed in the drainage ditch 4. A storage mechanism 7 is fixedly installed on one side of the support frame 6. A shading net 8 is installed inside the storage mechanism 7. A connecting rod 9 is fixedly connected to one end of the shading net 8. A corresponding bracket 10 is fixedly connected to the connecting rod 9. The bracket 10 is engaged with the support frame 6. By pulling the shading net 8 through the connecting rod 9, the shading net 8 covers the support frame 6, thus shading the lichen planting area.

[0046] The storage mechanism 7 includes a housing 15, with a rotating shaft 18 rotatably connected inside the housing 15. A strip-shaped opening 16 is provided through the top of the housing 15. The shade net 8 passes through the strip-shaped opening 16 and is fixedly connected to the outer wall of the rotating shaft 18. One end of the rotating shaft 18 passes through the housing 15 and is fixedly connected to a turntable 17. A locking mechanism is provided on the turntable 17. By rotating the rotating shaft 18 through the turntable 17, the rotating shaft 18 can roll up the shade net 8 and store it.

[0047] The card holder 10 has a card slot 11, which is engaged with the support frame 6. The outer wall of the support frame 6 has a connecting groove 14. A connector 13, which is adapted to the connecting groove 14, is fixedly connected to the card holder 10 within the card slot 11. The connector 13 is built into the connecting groove 14 and is slidably connected to the connecting groove 14. The card holder 10 is provided with a locking bolt 12. The end of the support frame 6 away from the storage mechanism 7 has a threaded hole adapted to the locking bolt 12. A limiting rod is fixedly connected to the outer wall above the strip opening 16. The shade net 8 passes through the limiting rod. When the connecting rod 9 moves, the card seat 10 moves on the support frame 6 along with the connecting rod 9. The connector 13 fixedly connected in the card slot 11 of the card seat 10 is built into the connecting slot 14, thereby limiting the connection of the connector 13 and the connecting rod 9. By rotating the locking bolt 12, the locking bolt 12 is threadedly connected to the support frame 6, thereby fixing the connecting rod 9. At the same time, the limiting rod limits the shade net 8.

[0048] In step five, water pipes 5 are laid in the planting area. Water pipes 5 are equipped with spray nozzles. Water pipes 5 regularly deliver water and nutrient solution. The nutrient solution is a nutrient juice made mainly from wild alfalfa and a certain amount of wild grass, mixed with appropriate organic nitrogen, phosphorus and methyl methacrylate fertilizers. After the original seeds of the lichen are planted, water is sprayed every 3 hours through water pipes 5 to keep the growing environment moist. At the same time, the nutrient solution is watered 1-2 times a week to ensure the nutrition for the growth of the lichen.

[0049] Step six involves manual collection and screening to collect and screen the planted lichen.
