Winter mushroom cultivation techniques

The winter mushroom cultivation technique of straw mushroom originated in Nanhua Temple in Shaoguan, Guangdong Province. It was cultivated 300 years ago in China. It was introduced to overseas countries by overseas Chinese in the 1930s and is an important tropical and subtropical mushroom. The third largest cultivation of edible fungi, China's mushroom production ranks first in the world, mainly in southern China. Mushrooms are nutritious and delicious. Each 100g of fresh mushrooms contains 207.7 mg of vitamin C, 2.6 g of sugar, 2.68 g of crude protein, 2.24 g of fat, and 0.91 g of ash. Straw mushroom protein contains 18 kinds of amino acids, including essential amino acids 40.47-44.47%. In addition, it also contains various mineral elements such as phosphorus, potassium and calcium. In modern diets, people are paying more and more attention to food nutrition. Straw mushroom also appears on the table as a standing food, so the cultivation of straw mushroom has also received more and more attention.
The mushroom is a type of high temperature and high humidity type, suitable for growth in a constant temperature and humidity environment. The suitable temperature for the growth of the straw mushroom is 23 to 25°C, and the relative humidity of the air is 85% to 95%. Therefore, by moving the high-temperature grass mushroom to the low temperature winter season for cultivation, it must be cultivated in a greenhouse with good heat preservation capacity, thereby increasing the cost of raising the temperature and other aspects. Moreover, the straw mushroom produced in winter is twice the price of conventional cultivation in the summer, so it should be adjusted properly from the aspects of the formulation of cultivation materials and cultivation management, in order to increase the input-output ratio and improve economic efficiency. The main techniques for the winter cultivation of straw mushroom are described below.
First, choose the appropriate formula of culture materials, build piles of fermented straw mushroom back-season cultivation can not use a single nutrient formula with low nutrient, low yield, should use a nutrient-rich, high biological efficiency formula, such as the use of microbial microbial fertilizer, or Fertilizers are used to ferment human and animal manure at the place where fertilisers are used. 68% cottonseed hulls, 20% straw, urea 1%, lime 6%, calcium carbonate 3%, plant ash 2% or waste cotton 77%, straw 10%, wheat bran 5%, lime 8%. Using the secondary fermentation method, the cottonseed hulls are exposed to sunlight for 3 to 4 days, and the moisture content of the material is adjusted to 70% to 75% with lime water, and the pH value is 7-8. Days, then the material was moved to room, kept at room temperature 60 °C for 2 days or the material temperature of 70 °C for 10 hours.
Second, the use of gold treasure greenhouse warming agent preparation of winter greenhouses
1. Soil preparation and fertilization: remove field stubbles 15-20 days before planting, and deep-rotate flat stubble; fine-quality decomposed farmyard fertilizers (such as chickens, cattle, horses, sheep and other livestock excrement) 3-4 square centimeters per mu , After mixing with 70% of compound fertilizer and chemical fertilizer dosage, spread spatula evenly.
2. Standards for width and trenching: After fertilization for soil preparation, the width of 1.2-1.3 meters in width shall be crossed, and 40 centimeters wide in the middle and 30 centimeters in depth shall be used. The soil to be excavated shall be placed on both sides. .
3, the preparation and dosage of goldfish strains (fermentation agent): about 4 kg (4 bags) of Jinbao starter per mu, 40 kg of wheat bran or rice sugar, (about 3 kg of 60m 7m shed. 30 kg of bran or rice sugar, the newer the better.) Mix 1 kg of bacteria with 10 kg of rice sugar and mix evenly. Add about 8 kg of water to mix evenly. You can also mix the good bacteria at 20-25°C for 12-24 hours. (Add water and humidity standard. With hand-poured with good material, fingers see the water droplets do not drip is appropriate).
4, put the straw and fermentative agent: the prepared corn stalk flat put the ditch, after compaction is consistent with the ditch along the edge; straw put, first with 2% urea aqueous solution, spray wet surface straw, Then, the prepared fermentation bacterium was evenly spread on the straw and beaten with iron milling, and the vibration was properly applied to make the part of the fungus fall in the straw layer. It is recommended to use fertilizer to put in 1-2 parts per mu of chicken droppings (or Other livestock manures are evenly mixed with the remaining 30% of fertilizer compound fertilizer. Fertilizer application above can increase fertility and extend fertilizer effect for more than 1 year. The effect is better. This fertilizer can also be used to stratify the middle of straw, but Do not use too much. .
5. Cover soil and irrigation: After the straw, fungicide and fertilizer are applied, cover the soil. Cover the soil with 90% of the excavated earth and put it on the straw. Make sure that the straw is not damaged and the thickness of the soil is about 20 cm. , forming a high sorghum. The remaining 10% of the soil can be made on the channel to a slightly higher point to facilitate the aisle and watering. After the soil is planted, about 10 or so watering, the straw drenched. Watering 2-3 Day afterwards tidy up again. Prepare for colonization. .
6. Colonization and drilling: When planting, open the ditch or dig a hole to plant the seedlings at the distance of 5-10 cm from the ditch. Before the planting, plant the fertilizer (biofertilizer), fungicides, insecticides, and plant the ditch, and drench it. Planting water. Immediately after planting, drill a hole in the return pile. Use 3 cm thick tipped wood brazing or steel brazing to drill holes. The depth of the hole is about 15 cm to penetrate the straw layer diagonally. The purpose is to For good ventilation and release of carbon dioxide. .
Third, sowing and mushrooming before the management of the culture material fermentation is completed, adjust the moisture content of 65%, pH value of about 9, when the material temperature dropped to 35 °C can be sowing, can be used to spread the material spread bar, will soon 80 centimeters in width is divided into 5 equal parts, each width is 16 centimeters, the middle one is filled with fertilizer soil, each side is filled with material, the amount of material used is 10 kilograms per square meter, the material shop is slightly compacted and the strains are spread on the material surface. Use seed weight of 4% to 6%, then sprinkle a layer of culture material on the strain, and apply 5-6 cm of fat on the outside of the two culture materials, close the mushroom shed to make the shed reach 30 ~ 35 °C, 3 days to maintain high temperature and humidity without opening doors and windows, in order to facilitate the germination of mycelium. After ventilation every day for about 20 to 30 minutes, after 4 to 5 days when the mycelium eats material 2/3, you can spray a small amount of water, promote hyphae to eat through the material, 6 days after the mycelium long material, should be properly adjusted to the water , To enhance ventilation and light ventilation, promote the formation of fruiting bodies, 8 days after the beginning of the kinks mushroom buds, at this time, the material surface should be properly dried to increase the mushroom and reduce dead mushrooms.
Fourth, to strengthen the management of fruiting period, timely harvesting Seen after planting 10 days or so, the small white spotted mushroom buds appear densely and gradually grow up, and the first tidal mushroom can be harvested in 13 to 15 days; Production accounts for 60% to 70% of total production. Therefore, we must strengthen the management of temperature, humidity, gas and light. In the formation of mushroom buds, strengthen the exhaust ventilation and adjust the room temperature, room temperature to maintain 32 ~ 34 °C, air relative humidity to maintain 85% ~ 90%, reduce the amount of water spray. Increase the number of water spray. After each tidal mushroom is harvested, it is necessary to promptly clean up the surface of the material. Under the premise of keeping the temperature of the mushroom house basically stable, it will be sprayed with moisturizing agent to adjust the pH to a more alkaline condition and promote hyphae recovery. Supplementing water at the same time can make up some nutrient solution such as 0.1% urea and 5% bran water to promote the differentiation and development of fruit bodies. After 7 days, the second tidal mushroom can be harvested. If the objective is to harvest tidal mushroom, a production cycle takes about 20 days.
The straw mushroom grows very fast and often has an umbrella overnight, so it should be harvested in time. When the straw mushroom from the base wide, the top slightly sharper pagoda shape into an oval, mushroom quality from hard to soft, the color from deep to shallow, the capsule is not broken, the stipe cap was not out of the harvest when the most suitable. Usually harvested once in the morning, evening and evening. The fresh mushrooms that are harvested can be sold or processed by cutting off the mud on the surface of the mushrooms in time.
