Tea tree mushroom cultivation: how can tea tree mushroom grow with high yield?

How can tea tree mushroom be planted with high yield? Please guide the method of planting Pleurotus ostreatus if you want to obtain high yield, you can refer to the following methods: first, growth conditions of Pleurotus ostreatus 1, nutrition. Pleurotus ostreatus is a kind of wood-rot fungus which has weak ability to decompose lignin and cellulose. Wild Pleurotus ostreatus is only born on Camellia oleifera. After artificial domestication, broad-leaved trees such as paulownia, maple, willow, oak and poplar can be used as cultivation materials. However, the miscellaneous sawdust with loose material and less tannin is more suitable for the growth of Pleurotus ostreatus. Wheat bran, rice bran and cake fertilizer can be fully used as nitrogen sources. In addition to the use of sawdust, bagasse, rice straw, cottonseed hull and fungus straw can also be used as carbon sources. Among the carbon sources, monosaccharides and disaccharides are the best, while starch and cellulose are weak. If there is only glucose in the culture formula, the mycelium growth is loose, and a small amount of sucrose is used, the mycelium will grow dense and flourish. It shows that mineral elements are needed in the process of mycelium growth. 2. Temperature. Pleurotus ostreatus is a medium-temperature edible fungus. On PDA medium, the spores could germinate in 24 hours under the condition of 26 ℃, and the fine hyphae could be seen with naked eyes after 48 hours. The optimum temperature for mycelium growth was 23 ℃ 28 ℃, stopped growing over 34 ℃, and could be preserved for 3 months at 4 min below zero. The temperature range of primordium differentiation of fruiting body was 12 ℃ 26 ℃, and the optimum temperature was 18 ℃. Lower or higher temperature would delay primordium differentiation. Low temperature, slow growth of fruiting body, but strong tissue, large mushroom shape and good quality; higher temperature, easy to open umbrella and form Pleurotus ostreatus. 3. Moisture. The water content of the culture medium for the cultivation of Pleurotus ostreatus should be controlled at 60%, 65%, that is, grasp a handful of the medium by hand, squeeze it hard, moist between the fingers, slightly drop but not flow, the fingers are loosened into pieces, and it is appropriate to spread out after landing. However, different kinds of sawdust and thickness are slightly different, so they should be mastered flexibly. When the mycelium grows, the air relative humidity is required to be less than 70%; the fruiting body formation and development period is 85% Mel 95%, and the growth period is appropriately reduced to prolong the product shelf life. 4. Air. Tea tree mushroom is a kind of aerobic macrofungus, which is very sensitive to carbon dioxide, and the concentration of carbon dioxide in poor ventilation is too high, which is easy to cause slow growth of mycelium, thick and long stalk of fruiting body, small cap, early opening of umbrella, deformed mushroom and so on. 5. Light. Pleurotus ostreatus is a light-dependent fungus, the fruiting body has the characteristics of phototaxis growth, and appropriate diffuse light is a necessary condition for the completion of normal life cycle. During the mycelium culture, the mycelium still grew in the absence of light, but did not form a fruiting body. The fruiting body is not easy to differentiate without light, and the suitable light intensity is 50ml / 300L. 6. acidity and alkalinity. The mycelium of Pleurotus ostreatus likes weak acid environment and is the most suitable for pH5.5-6.5. The mycelium grows sparsely and slowly below or above pH 4. Second, the method of seed production of Pleurotus ostreatus can be cultivated in spring and autumn. The cultivation season should be arranged according to the local temperature change law, and the appropriate time should be selected for cultivation. The practice shows that a large number of fruiting bodies will be formed when the temperature drops to 24 ℃ in the high temperature season and rises to 18 ℃ in the low temperature season. Therefore, the local temperature for spring planting is stable at 18 ℃ for 2 months, and the autumn temperature is stable at 24 ℃ for 2 months. (1) the production of bacteria. The production time of the cultivated species is equal to the number of days needed to push forward the cultivation of the cultivated species, and the production time of the original seed is equal to the actual opening days of the original seed cultivation forward. By the same method, the production time of the mother seed can be calculated. The culture time of Pleurotus ostreatus strains varies greatly in different media under the same culture conditions. 1. Mother seed production: the mother species of Pleurotus ostreatus is often selected from the cultivated or wild fruit bodies to be used as tissue separation materials with good growth and round shape. Through the adaptability test, the strains with good comprehensive economic characters were selected and used for demonstration and promotion. Formula 1: 200g potato, 20g glucose, 20g Agar, 1000 ml water, natural pH. Formula 2: 200g potato, 5g glucose, 5g sucrose, 20g Agar, 50g wheat bran (boiled juice), 0.15g magnesium sulfate, 1000 ml water, natural pH. According to the conventional preparation, sub-packaging, sterilization, bevel preparation. Isolation and culture. Under the aseptic condition, the stalk was cut short and broken longitudinally. At the connection between the stalk and the cap, a small piece of tissue was removed and transferred to the bevel medium. When the mycelia were cultured in a 25 ±2 ℃ incubator, the mother species was the mycelium growing all over the slope. 2. Original seed and cultivated seed production and culture: culture medium and production: the original seed commonly used wheat grain medium or sawdust medium, packed in mushroom bottles. Because of the large amount of seeds, sawdust is often used as the main raw material as the culture medium and packed in polypropylene bags, and the sawdust medium is the same as the cultivation material. Mix the raw materials with water (wheat grains need to be soaked and boiled), then put them into bottles and bags and compact them. Make a hole in the middle, clean the sticky material in the bottle bag, make the cotton plug, sterilize and cool according to the routine. Inoculation culture: the mother seed (or original seed) was inserted into the sterile condition, and each mother seed could be connected with about 5 bottles of the original seed. The cultivated species were cultured for 45 days, and the hyphae could grow full of bottles (bags). 3. Cultivation techniques of Pleurotus ostreatus: cultivation of Pleurotus ostreatus is divided into spring planting and autumn planting according to season. In spring cultivation, the mycelium culture stage needs proper heat preservation, the temperature rises in the later stage of fruiting body growth, grows fast, the fruiting body shape is small, the quality is relatively poor, and it is easy to be harmed by diseases and insect pests; in autumn cultivation, after inoculation, the mycelium culture temperature is more suitable. The fruiting body formed at lower temperature has larger blossom shape, good quality, less pollution of diseases and insect pests, higher bioconversion rate and good economic benefit. The cultivation sites can be cultivated indoors or outdoors, and the cultivation forms can be divided into shelf bag cultivation, wall bag cultivation and bed soil mulching cultivation. All localities can choose according to local conditions. (1) medium formula 1: miscellaneous sawdust 76%, wheat bran 20%, sugar 1%, calcium superphosphate 1%, calcium carbonate 1%, gypsum 1%. Formula 2: miscellaneous sawdust 68%, wheat bran 15%, tea seed cake powder 15%, sugar 1%, gypsum powder 1%. Formula 3: 58% sawdust, 20% cottonseed hull, 20% wheat bran, 1% sugar, 1% gypsum powder. Formula 4: miscellaneous sawdust 60%, bagasse 18%, wheat bran or rice bran 20%, calcium superphosphate 1%, gypsum powder 1%; formula 5: miscellaneous sawdust 60%, corncob 20%, wheat bran or rice bran 19%, gypsum powder 1%; the water content of the above formula is 60%, natural pH, autumn cultivation should add 0.1% 0.2% carbendazim Camellia oleifera cultivation area can add 10% tea seed shell powder, which can effectively increase the yield. (2) Indoor bag cultivation can make use of greenhouse, mushroom house and idle house, etc., and the cultivation of spontaneous bacteria to mushroom production can be completed in the same place. The environmental microclimate of indoor bag planting is easy to be controlled artificially, easy to manage, easy to obtain high quality and high yield, and is also suitable for factory cultivation. 1. The places used for indoor bag planting should be clean and sanitary, far away from workshops, warehouses and poultry sheds, and have good temperature regulation and light transmission. Comprehensive disinfestation and disinfection must be carried out before cultivation. First, after cleaning and cleaning, the insecticidal solution of dichlorvos of 800 times is sprayed, and after 5 days, it is fumigated with sulfur or formaldehyde solution to control the breeding of miscellaneous bacteria. 2. Mix and sterilize separately according to the selected cultivation material formula, weigh all kinds of raw materials, add water to mix evenly so that the water content can reach 60% 65A / e, pack the polypropylene corner bag with 17 × 33 × 0.005 cm polypropylene corner bag by hand or bagging machine, relax and tighten uniformly, the material surface is flat, the loading height is 13Muth15cm, and seal with non-cotton cover body or ring cotton plug. The sterilization was kept for 10 hours at 100 ℃ at normal pressure, and sterilized overnight or at 0.138 MPA at high pressure for 1.5 hours. 3. Inoculate and cultivate the sterilized and cooled material bag, pick up the person under aseptic condition, inoculate and cultivate seeds with shovel, and plug without cotton cover body or ring cotton plug. Try to block the bacteria to avoid fragmentation to prevent the death of the seed. The inoculated bacterial bag was placed vertically on the indoor shelf and cultured under the condition of 25i 2 ℃ for 55 days. The hyphae filled the whole bag. During the germicidal period, the room should be kept as dark as possible. 4. Harvesting and processing of Pleurotus ostreatus not only the cap is edible, but also the stalk is very fragile and tender, so it should be harvested with the cover and handle. When the fruiting body grows, the cap is still curled, and the spores are not yet harvested. One-time harvest can also be used to harvest large and small, old and young in batches, and attention should be paid to the protection of young mushrooms when harvested in batches. Generally, 4 batches of fresh mushrooms can be harvested, and 60 kilograms of fresh mushrooms can be produced for every 100 kg of dry material.
