Description

Technical Field

[0001] The invention relates to the technical field of matsutake mushroom propagation promotion, and in particular to a method for preserving, promoting propagation and increasing yield of matsutake mushroom. Background Art

[0002] Matsutake, a name derived from China, was recorded in Tang Shenwei's book "Jingshi Zhenglei Beiji Bencao" (1082-1094) during the Yuanyou period of Song Zhezong. It was named because it grows under pine trees and its buds are like deer antlers. Also known as pine mushroom, pine mushroom, etc., it is a plant of the genus Trichoderma of the family Trichostomaceae. It is an exogenous mycorrhizal fungus of trees such as pine and oak. It is a rare and precious natural medicinal fungus in the world. It is known as the "king of fungi" and is a second-level endangered species in China. Fresh matsutake is umbrella-shaped, bright in color, with a brown cap and a white stipe. Both have fibrous hair scales, white and tender flesh, fine texture, and a strong special aroma. It is mainly produced in the Qinghai-Tibet Plateau area such as Sichuan, Tibet, and Yunnan. It grows in pine forests with an altitude of 1600m to 4200m and a tree age of more than 20 years. It has high requirements for the growth environment and needs to form mycorrhizal fungi with pine trees to grow. They need to rely on the roots of pine trees to survive. The species include Qinggang Tricholoma matsutake, false pine tricholoma, chestnut brown pine tricholoma, etc. Matsutake is rich in protein, 18 kinds of amino acids, 14 kinds of essential trace elements for the human body, etc.

[0003] Previously, researchers tried to develop artificial cultivation technology for Matsutake, including rapid synthesis of seedling mycorrhiza, synthesis of artificial mycorrhiza in mature forests, and induction of artificial fungus ponds, but with little success. In 2020, Matsutake was listed as an endangered species in the world (Red List) by the World Conservation Union. Due to the lack of research on the conservation and propagation technology of Matsutake, the Matsutake currently on the market are all collected from the wild, which is far from meeting people's needs. Therefore, it is necessary to provide a method for conservation, propagation and production increase of Matsutake. Summary of the invention

[0004] In order to overcome the problems existing in the background technology, the present invention can increase the yield of Matsutake and improve the quality of Matsutake, thereby promoting the sustainable and healthy development of the wild edible fungus industry.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a method for preserving, promoting the propagation and increasing the yield of Tricholoma matsutake, comprising the following steps:

[0007] (1) After the matsutake mushrooms are found to have emerged from the soil, the mushrooms with a stem diameter of 2-3 cm are selected and covered with substrate. When the fruiting bodies are 0-2 cm above the ground surface, they are covered with yellow sand soil; when the fruiting bodies are 2-3.5 cm above the ground surface, they are covered with black sand soil; when the fruiting bodies are 3.5-5 cm above the ground surface, they are covered with humus soil;

[0008] (2) First, pile up the matrix around the unearthed matsutake mushrooms to form a base, then continue to cover the matrix on the top of the matsutake mushrooms and pile it into a cone shape. After 2-3 days, cover it again with the same matrix, and repeat this process twice;

[0009] (3) Insert the two ends of the bamboo strips or branches into the soil above the matsutake mushrooms and the substrate to form a high

[0010] A 25-40cm arch shed is built and covered with cardboard and dead branches and leaves; the construction of the arch shed can prevent rainwater from eroding the soil and causing it to become compacted and less breathable, thus affecting the growth of the fruiting bodies of Matsutake.

[0011] (4) Matsutake mushrooms are harvested 6-8 days after they emerge from the soil. At this time, their commercial value is maximized and it is suitable for harvesting.

[0012] In the above technical solution, the matrix includes yellow sand, black sand and humus soil, and the pH value is 5-6.

[0013] In the above technical solution, the yellow sand soil has a particle size of less than 20 mm, a porosity of 14%-28%, and a bulk density of 1.1-1.4 g / cm 3 , air-water ratio 1:4-10, humidity 17%-25%.

[0014] In the above technical solution, the black sand has a particle size of less than 20 mm, a porosity of 24%-35%, and a bulk density of 1.2-1.4 g / cm 3 , air-water ratio 1:6-11, humidity 20%-25%.

[0015] In the above technical solution, the humus soil has a particle size of less than 20 mm, a porosity of 30%-40%, and a bulk density of 0.7-0.9 g / cm 3 , air-water ratio 1:5-9, humidity 50%-70%.

[0016] In the above technical solution, the matsutake mushrooms grow in a woodland environment with an altitude of 1600-2900m, a rainfall of 800-1000mm, a sunshine duration of 2200-2400h, an average annual temperature of 16-22°C, and a soil temperature of 9-20°C.

[0017] In the above technical solution, the height of the stacked cones in step (2) needs to be greater than 20 cm.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention changes the covering matrix, uses yellow sand, black sand and humus as the covering matrix, and uses different covering matrices according to the different sizes and growth conditions of the matsutake after unearthed, thereby changing the microenvironment for the growth of the matsutake, thereby promoting the matsutake to grow continuously and grow out of the ground. Under this method of conservation and propagation promotion, the length of the matsutake mushroom body increases by 6-8 cm, and the weight of a single matsutake fruiting body also increases by 40-60 g. The weight of each matsutake is 90-130 g, which improves the yield and quality of the matsutake and expands the production efficiency.

[0020] 2. The present invention selects a suitable covering matrix according to the different sizes and growth states of the matsutake mushrooms after they are unearthed, selects soil with suitable soil bulk density, porosity and water content, and makes slight adjustments to the growth environment of the matsutake mushrooms so that the matsutake mushrooms are in a more suitable environment during the spore germination period and the mycelium growth period, thereby extending the vegetative growth period of the matsutake mushrooms, increasing the length, height and weight of the matsutake mushrooms, and delaying the opening time of the matsutake mushrooms, thereby preventing the spores from scattering after the matsutake mushrooms open and reducing the nutritional value. The yield of the matsutake mushrooms will be greatly increased, and the quality will also be improved, thereby greatly improving the economic benefits.

[0021] 3. The method of the present invention is simple to operate, easy to be widely promoted and applied, and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS
