Small tricks to increase oyster mushroom yields: learn these methods for higher production
1. Water with mushroom root water. Put the mushroom roots trimmed off after adding into a pot, add water just to cover them, boil for 20 minutes, take the filtrate, add 7-10 times clean water, and pour it into the water trough on the mushroom wall after harvesting the first flush. This liquid has complete nutrition and is absorbed and converted quickly, generally increasing yield by 10%. 2. Spray hormones. During the young bud stage, spray 0.5‰ ethephon solution once each during the oyster mushroom bud stage, young mushroom stage and cap expansion, 50 ml per square meter each time, which can promote budding and early maturity and increase yield by 20%. 3. Spray trace elements

How to control humidity for higher yields when growing oyster mushrooms indoors?
When growing oyster mushrooms indoors, humidity control is the key to success, and management after fruiting begins is especially important. At this stage, if the humidity is too low, the mushrooms will shrivel, stop growing, or even die; if the humidity is too high, the mushrooms rot easily. Practice has shown that controlling humidity by spraying water is hard to master, and sometimes spraying too heavily on the surface of the substrate affects the development of mushroom buds, causing young mushrooms to die and reducing or even wiping out the harvest. Here is a clever method that controls humidity without spraying water and can also increase oyster mushroom yields. Get some cotton cloth and a jar, cut the cotton cloth into a strip 8 cm x 40

Adding table salt to oyster mushroom substrate can increase yields
In oyster mushroom cultivation, using carbendazim to control contamination by foreign fungi is effective, but pesticide residues remain in the mushrooms, which is harmful to human health, and the cost is relatively high. According to experiments: when cultivating oyster mushrooms on raw substrate, adding 1.5 kg of table salt per 100 kg of dry substrate (dissolved in advance in a measured amount of water) and mixing thoroughly can prevent infection by foreign fungi and also bring mushrooms out 5-7 days earlier. At the same time, because table salt is rich in sodium, calcium, magnesium and other metal ions needed for oyster mushroom growth, if a 10% salt solution is sprayed in the early stage of fruiting body differentiation and after each flush is harvested, the mushrooms can be free of pesticide residues and their quality

Seven methods of applying nutrient solutions to increase oyster mushroom yields
1. Sucrose and calcium carbonate phosphate mixed solution: sucrose 1%, calcium carbonate 1%, potassium dihydrogen phosphate 0.1%. Use when the mycelium has covered the mushroom bed and before fruiting bodies appear. 2. Urea and citric acid mixed solution: urea 0.5%, citric acid 0.1%, adjust pH to 7 with sodium hydroxide. Use after the first flush of mushrooms is harvested. Using it after the second flush is not effective and instead hinders oyster mushroom growth. 3. Sugar, urea and citric acid mixed solution: sucrose, citric acid and urea 1% each, adjust pH to 7. Same

Semi-underground three-dimensional cultivation of oyster mushrooms yields high output and good returns
Semi-underground three-dimensional bed-frame cultivation of oyster mushrooms is a new approach explored in recent years to achieve high yields and improve economic returns. According to trials, on an area of 20 sq m, with 2000 kg of substrate, the annual output of oyster mushrooms is about 2500 kg, with a biological efficiency of over 120%. The key technical points are as follows: 1. Building the greenhouse: first dig a pit 1.8 m to 2 m deep and 4 m to 5 m wide, with the length determined as needed, and place the three-dimensional bed frames inside. On top, use bamboo poles and plastic film to build an arched shed, pack the surrounding edges firmly with soil, and cover with straw mats. Leave ventilation openings of about 30 square cm on all four sides, east, west, north and south, and build a small door on the west side for workers to enter and exit.

High-nutrition formula cultivation of oyster mushrooms can achieve exceptionally high yields
The high-nutrition, exceptionally high-yield cultivation technique for oyster mushrooms uses raw materials such as wheat straw and rice straw, and adopts measures including high-nutrition formulas, removing the plastic casing from the mushroom logs, and covering with nutrient soil, so that the input-to-output ratio reaches more than 1:10, with very significant economic benefits. 1. Strain selection: choose wide-temperature varieties such as Changbai No. 1. The suitable cultivation time is from September of the current year to April of the following year. 2. Formula and treatment: there are 4 formulas: ① 50% soybean straw (crushed), 40% corncob or wheat straw, 8% cornmeal or wheat bran, 2% lime. ② 70% wheat straw, 27% wheat bran, 1% compound fertilizer

For lilies to achieve high yields, doing the three changes well is key
1. Change from using inferior seed bulbs to high-quality seed bulbs. Choose excellent varieties such as Longya lily as seed. Lilies need to be purchased from other regions as seed, which is an important measure for lily rejuvenation. Choosing seed bulbs with little or no virus is the key to high-yield lily cultivation. At the same time, pay attention to choosing thick, plump, and large seed bulbs. Use bulbs propagated from scales or directly use the daughter bulbs from the mother bulb as seed. 2. Change from sowing too early to sowing at the right time. Sowing too early makes it easy to encounter drought, often causing seed rot, and the high temperatures in early August are not conducive to breaking the dormancy period of lily seed bulbs. After sowing, roots often do not grow, and it is prone to

How can outdoor cultivation of Gastrodia elata achieve high yields?
Artificial cultivation of Gastrodia elata adapts to a very wide range of conditions; regardless of the height of the mountain, regardless of shady or sunny slopes, and regardless of sandy or loess soil, Gastrodia elata production can be developed. So how can high yields be obtained? ① Flat planting on hillsides. In mountainous areas with heavy autumn waterlogging and rain, when Gastrodia elata is planted in pits, except in a few well-drained places, the pits mostly accumulate water, causing rot and reduced yields. Cultivation by piling soil on the slope surface occupies much land and is easily affected by summer drought and high temperatures, which is unfavorable to the growth of Armillaria mellea and Gastrodia elata, making high yields difficult to obtain. However, bed planting or horizontal cultivation can achieve high yields. The method is: on slopes above 25°C, because rainwater

Why oyster mushroom logs grown with casing soil produce high yields
Bagging and inoculation: Select fresh cottonseed hulls, add 1% gypsum, 1% lime and 0.10% carbendazim, with a material-to-water ratio of 1:1.3-1:1.5. After mixing evenly, pile on a concrete floor to ferment for 3-5 days, then bag. When bagging, first tie one end of the material tube firmly, add a small amount of spawn, then when the material fills half the bag, sow 5-6 pieces of spawn the size of red dates at the edges of the material, then continue filling with material; once the bag is full, sprinkle a layer of spawn on the surface of the material and tie the bag opening firmly.

What are the reasons why oyster mushroom yields are getting lower and lower
Recently, many growers have called to ask: why are oyster mushroom yields getting lower and lower these days? Compared with previous years, the difference is far too great. For this reason, the author conducted a survey and found the following problems: Serious pollution of the cultivation environment. The vast majority of growers cultivate in greenhouses year after year. Deteriorating environmental conditions and incomplete disinfection are the main reasons for reduced oyster mushroom yields. According to tests, the background count of contaminating microorganisms in a new site was 63.95 per square meter, with bacteria accounting for 95%, and 150 colonies per square meter. After the first cultivation cycle ended, the background count of contaminating microorganisms was 20 times higher than before. These contaminating microorganisms control the growth of oyster mushrooms to some extent, and the more cultivation cycles there are, the lower the oyster mushroom yield.
