Technical Field

[0001] The invention relates to the technical field of edible fungus cultivation, and in particular to a method for simulating wild cultivation of red stem bamboo fungus by utilizing dead bamboo resources. Background Art

[0002] As an important species in the development of the edible fungi industry in Guizhou Province, the red-stemmed bamboo fungus has the characteristics of high yield, rich nutritional value and crisp taste. Other studies have shown that the wild resources of the red-stemmed bamboo fungus are distributed in different bamboo forests. Bamboo provides nutrition for the growth and development of the red-stemmed bamboo fungus, especially the rotten and degraded bamboo can accelerate the growth and development of the red-stemmed bamboo fungus. In the traditional cultivation process of red-stemmed bamboo fungus, it often relies on broad-leaved tree chips or other non-renewable resources, and is often directly covered with soil during cultivation. Tongzi County, as a large county for the cultivation of square bamboo in Guizhou Province, has a large-scale native square bamboo forest resources. The current planting area of ​​square bamboo has exceeded 1 million mu. In order to increase the yield of bamboo shoots in square bamboo forests, it is necessary to thin out the bamboos that are too old in the square bamboo forests. The reuse rate of felled bamboo is low, and the waste of resources is serious. Therefore, it is necessary to rationally utilize square bamboo forest resources to plant red-stemmed bamboo fungus without affecting the yield of bamboo shoots, form a "bamboo fungus, bamboo, and bamboo shoots" three-bamboo industry, and develop a red-stemmed bamboo fungus cultivation method that efficiently utilizes dead bamboo resources to achieve sustainable utilization of resources and increase economic benefits. Summary of the invention

[0003] To solve the above problems, the purpose of the present invention is to provide a method for simulating wild cultivation of red-stemmed bamboo fungus using dead bamboo resources, which can improve the reuse rate of felled bamboo, save resources, reduce the planting cost of red-stemmed bamboo fungus, achieve sustainable utilization of resources and increase economic benefits.

Example

[0018] This embodiment provides a method for simulating wild cultivation of Dictyophora rubra using dead bamboo resources, comprising the following steps: S1. Thin out the over-old bamboos in the other party's bamboo forest, dig out the bamboo whips and bamboo roots, and shave off the bamboo branches and bamboo leaves on the edge of the bamboo poles. Then, pile up the bamboo poles, bamboo whips, bamboo roots, bamboo branches and bamboo leaves separately for later use.

[0019] S2. Crush bamboo whips, bamboo roots, bamboo branches and some cracked bamboo poles into particles and soak them in water for more than a week to prepare the broken bamboo residue for later use; mix the rotten bamboo leaves under the forest with sandy loam in a ratio of 1:3, add 0.5 times water and ferment for 1 month, then spread it out and expose it to the sun for 2-3 days to prepare humus soil for later use.

[0020] S3. Prepare the culture soil, which is made by composting the following raw materials in weight percentage: 62% crushed bamboo residue, 23% humus, 1% sugar, 1% calcium sulfate, 0.2% potassium dihydrogen phosphate, 0.07% magnesium sulfate, and adjust the pH to 5.1 with 1% citric acid. The water content of the culture soil is 70%.

[0021] S4. In July, trenches 2 were dug downwards on the soil layer 1 in the gaps of the bamboo forest at an altitude of 1,300 meters. Figure 1 As shown, the cross section of the groove 2 is an inverted trapezoidal structure, and the depth of the groove 2 is about 45 cm.

[0022] S5. Stack two or more water collection layers 3 from bottom to top at the bottom of the trench 2, such as Figure 1 and Figure 2As shown, each water collection layer 3 is composed of a plurality of first arc-shaped bamboo pieces 31 placed side by side with the concave surface facing upwards and a plurality of second arc-shaped bamboo pieces 32 placed with the concave surface facing downwards, wherein a second arc-shaped bamboo piece 32 is placed above two adjacent first arc-shaped bamboo pieces 31 to form a primary water storage layer at the bottom of the ditch. The two adjacent first curved bamboo pieces 31 are parallel to each other and there is a gap between them. The second curved bamboo piece 32 covers the gap between the two adjacent first curved bamboo pieces 31, and the second curved bamboo piece 32 contacts the tops of the two adjacent first curved bamboo pieces 31 directly below it through the bamboo nodes on its inner side. At the same time, the two ends of the cross section of the second curved bamboo piece 32 extend to the tops of the two adjacent first curved bamboo pieces 31 directly below it and are suspended in the air. After being arranged in this way, the suspended second curved bamboo piece 31 can block the water vapor evaporating from the soil. After the water vapor rises and hits the inner side of the second curved bamboo piece 32, it condenses into water droplets and slides along the edge of the second curved bamboo piece 32 into the first curved bamboo piece 31 for storage. After the water content of the filling layer above the first curved bamboo piece 31 decreases, the water in the first curved bamboo piece 31 can replenish water to the filling layers on its upper side. After the water content of the filling layer above the first curved bamboo piece 31 increases, the excess water flows down and enters the first curved bamboo piece 31 for storage. The first curved bamboo piece 31 and the second curved bamboo piece 32 are both arranged along the length direction of the groove and are obtained by breaking the bamboo piece 31 along the axial direction with a bamboo pole. The cross-sectional curvature of the first curved bamboo piece 31 is about 2 / 3π to 3 / 2π, and the cross-sectional curvature of the second curved bamboo piece 32 is about 2 / 3π. At the same time, the bamboo node plates on the inner side of the bamboo nodes of the first curved bamboo piece 31 are not removed, thereby dividing the interior of the first curved bamboo piece 31 into multiple natural water storage chambers.

[0023] S6. A lower filling layer 4 made of bamboo slag is laid on the (uppermost) water collection layer 3 as a secondary water storage layer and water vapor channel. The water content of the lower filling layer 4 is above 85%. The lower filling layer 4 is relatively loose inside, which is convenient for water to penetrate up and down.

[0024] S7. A middle filling layer 5 made of a mixture of bamboo slag and humus soil is laid on the lower filling layer 4 as a third-level water storage layer and a nutrient supplement layer; the water content of the middle filling layer is also above 85%. The weight ratio of humus soil to bamboo slag in the middle filling layer is 1:4.

[0025] S8. In the filling layer 5, a culture tank 6 (one or more) is set up along the length of the groove 2 for cultivating red bamboo fungus; as Figure 1 and Figure 3 As shown, the culture tank 6 is a trough-shaped body surrounded by a lateral bamboo tube 61, a bottom bamboo tube 62 and a bridging bamboo tube 63 and filled with a culture medium 7, wherein the lateral bamboo tube 61, the bottom bamboo tube 62 and the bridging bamboo tube 63 are all obtained by breaking a part of bamboo along its axial direction to form an axial opening to expose its interior.

[0026] There are two lateral bamboo tubes 61 , and the axial openings of the two lateral bamboo tubes 61 face downward and are arranged on the middle filling layer 5 along the length direction of the groove 2 .

[0027] There are two bottom bamboo tubes 62 and they are arranged between the two lateral bamboo tubes 61 along the length direction of the groove 2. The axial openings of the two bottom bamboo tubes 62 face upward and are embedded in the middle filling layer 5. The side of each bottom bamboo tube 62 extends to the bottom of the lateral bamboo tube 61 on the same side. The bottom bamboo tube 62 is filled with a water-retaining material 8 that contacts the bottom of the culture medium 7.

[0028] The bridging bamboo tube 63 is arranged above the two bottom bamboo tubes 62 and covers the gap between the two bottom bamboo tubes 62 , and its axial opening faces downward. At the same time, both sides of the bridging bamboo tube 63 extend to the upper inner sides of the two bottom bamboo tubes 62 and contact the water-retaining material 8 in the bottom bamboo tubes 62 .

[0029] The portion of the middle filling layer 5 located directly below the lateral bamboo tube 61 protrudes upward and enters into the lateral bamboo tube 61, and at the same time extends into the bottom bamboo tube 62 to contact the water-retaining material 8, but does not contact the inner side of the lateral bamboo tube 61; the portion of the middle filling layer 5 located directly below the bridging bamboo tube 63 protrudes upward and enters into the bridging bamboo tube 63, and at the same time extends into the bottom bamboo tube 62 to contact the water-retaining material 8, but does not contact the inner side of the bridging bamboo tube 63.

[0030] The water-retaining material 8 is obtained by mixing humus soil, sandy soil and expanded bamboo residue in a ratio of 1:3:6. The expanded bamboo residue is obtained by expanding the bamboo residue with an expander. The water content of the water-retaining material 8 is above 85%.

[0031] S9. A layer of prepared culture medium 7 is spread in the culture tank 6, and then a plurality of holes are punched around the red bamboo fungus stick 9 and then sandwiched in the middle of the culture medium 7, and then the fungus material inside the red bamboo fungus stick 9 is evenly sprinkled on the surface of the culture medium 7. When the water and nutrients in the culture medium 7 are reduced, the water and nutrients in the water-retaining material 8 will continuously supplement the water and nutrients of the culture medium 7 (nutrient water is brought into the culture medium 7 with the flow of water). Similarly, the water-retaining material 8 is supplemented by the middle filling layer 5 on the one hand, and by the water condensed at the bottom of the inner side of the lateral bamboo tube 61 and the bridge bamboo tube 63 on the other hand. This part of water is the water vapor evaporated from the middle filling layer 5. After hitting the inner bottom of the lateral bamboo tube 61 and the bridge bamboo tube 63, it condenses into water droplets and slides along the edge of the lateral bamboo tube 61 and the bridge bamboo tube 63 to the water-retaining material 8 of the bottom bamboo tube 62. As for the supplement of nutrients in the water-retaining material 8, water is supplemented from the middle filling layer 5 to the water-retaining material 8, and is simultaneously brought into the water-retaining material 8 by the water. Similarly, the water in the middle filling layer 5 can also be supplemented through the lower filling layer 4 and the water collecting layer 3 below it, and the water in the lower filling layer 4 and the water collecting layer 3 is supplemented through the bottom soil, thereby ensuring the continuity of water, keeping the culture material 7 in a high humidity state, ensuring the humidity environment and nutrition required for mushroom production, and ensuring normal mushroom production.

[0032] S10. The middle filling layer 5 and the culture medium 7 are covered with an upper filling layer 10 composed of sandy loam, which has good permeability and facilitates the downward penetration of surface water; the thickness of the upper filling layer 10 directly above the culture medium 7 is 3-5 cm.

[0033] S11. A covering layer 11 is covered on the surface of the upper filling layer 10 to block the evaporation and rising water vapor in the soil, so that it condenses into water droplets and falls back into the soil; the covering layer 11 is composed of bamboo leaves and has a thickness of 2-5 cm.

[0034] After cultivation, mushrooms will appear in October, mycelium will attach to dead bamboo in November and December, and bamboo fungus will grow normally in March of the following year.

[0035] Other aspects of the present invention that are not described in detail are all conventional techniques known to those skilled in the art.

[0036] It should be noted that the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0037] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
