High-Temperature No. 9 oyster mushroom. (1) Characteristics: a high-temperature variety, growing in clusters; the cap is gray and turns dark gray when the temperature is below 20°C; the stipe is relatively firm; the gills are white; the fruiting bodies are relatively compact and dense, with high market quality. It is not susceptible to yellow mushroom disease or brown rot, and the biological efficiency of the first flush is about 150%. (2) Suitable temperatures: 6-38°C for mycelial growth, 12-36°C for fruiting.

How to cultivate high-temperature oyster mushrooms? Detailed explanation of key technical points
Late spring and early summer is a good time to cultivate oyster mushrooms. Because high-temperature oyster mushrooms fruit during periods of high air temperature and are prone to many diseases, the planted quantity is relatively small, but their price is 2 to 3 times that of the autumn-winter period. High-temperature oyster mushroom cultivation is technically difficult and the success rate is extremely low, so how to obtain high quality and high yield is a matter of greater concern to mushroom growers. Variety selection Many mushroom growers fail in cultivating high-temperature oyster mushrooms, mostly due to mistakes in variety selection. Some growers do not clarify the temperature type of the variety and plant casually, resulting in no fruiting or failure of mycelial growth because the temperature type is wrong, so it is essential to obtain spawn from

Key Techniques for Summer Cultivation of High-Temperature Oyster Mushrooms
As summer arrives and temperatures gradually rise, edible fungi on the market become increasingly scarce. Cultivating high-temperature oyster mushrooms for market at this time can yield considerable economic benefits. Variety selection. The main characteristic of high-temperature oyster mushrooms is tolerance to high temperatures; generally, any variety that can withstand 36°C can be selected. Currently, commonly used high-temperature varieties include 831, Shuangnai No. 3, and others. Cultivation method. Summer cultivation of oyster mushrooms is generally suitable for indoor growing, as this makes humidity easier to control. Bed width 80-100 cm, layer spacing 60 cm, with 6-7 layers possible, leaving

Introduction to the High-Temperature-Tolerant Wild Oyster Mushroom NP Variety
A pure strain obtained by tissue isolation after multiple collections of wild oyster mushrooms by the **Institute of Biological Soil and Desert Research, Chinese Academy of Sciences. The fruiting body primordia are solitary or clustered, and young primordia are white or light brown. The cap diameter is 10-12 cm, the thickness is 1-1.5 cm, and the cap is pure white or light brown. The flesh is white, the stipe diameter is 1.5-2.5 cm, the length is 2-6 cm, and the color is white. The spore print is white or light purple. It has wide adaptability and high-temperature tolerance, capable of fruiting at 30°C, but it can also fruit normally at a low temperature of 8°C.

Key points for azalea cultivation: suitable temperature is crucial
Azaleas are damaged when the temperature is too high or too low. Only under suitable temperature conditions can they develop and grow rapidly and robustly. Therefore, attention to the suitable temperature for azaleas should be a key point in azalea cultivation and management. Azaleas should be moved into a room with a temperature no lower than 5°C around Frost's Descent. During overwintering, different varieties have different temperature requirements. For example, summer azaleas should not be below 5°C, spring azaleas around 10°C, and Western azaleas about 8-15°C. It should be noted that below 3°C, varying degrees of cold damage may occur depending on the variety.

Azalea Biological Clock Disrupted by Temperature Changes
December 7 is Major Snow, one of the 24 solar terms in the lunar calendar, but at the Yuanjiajie Scenic Area in Wulingyuan, Zhangjiajie, at an altitude of 1100 m, large numbers of wild azaleas along the walking paths have produced fiery red blooms. In Mujiao Township, Tongdao Dong Autonomous County, Huaihua City, which has a well-preserved ecology, azaleas are also blooming in the wind. Azaleas generally bloom in early spring, so flowering in winter is truly rare. Amid a stretch of green shade, a cluster of purplish-red azaleas is blooming vibrantly, setting each other off against the cliff edge and the yellow leaves, drawing many tourists

High temperatures trigger heat stress in pigs, affecting their physical health
The high-temperature environment from June to September each year disrupts pigs' sex hormone secretion, throwing their normal estrus mechanism out of order, so that estrus symptoms become inconspicuous or the animals do not come into heat at all; high temperatures make pigs devote most of their energy to resisting heat stress, correspondingly weakening their other bodily functions, and for lactating sows and fattening pigs that need to eat large amounts of feed, this leads to insufficient nutrition and the phenomena of low milk output and slow growth; high temperatures make heat dissipation from the boar's testicles difficult, intensify sperm metabolism and shorten sperm lifespan, so that the motility of ejaculated sperm decreases or the sperm even die; high temperatures also increase the death of newly fertilized eggs and make implantation of the fertilized eggs more difficult, thereby lowering the conception rate of summer breeding.

Detailed Explanation of High-Temperature Open-Air Cultivation Technology for Shiitake Mushrooms Using Sawdust
The technology of cultivating shiitake mushrooms (Lentinula edodes) using sawdust as the raw material under high-temperature conditions of 30°C breaks the seasonal restrictions of traditional shiitake cultivation, allowing production in all four seasons. The method is: add water to sawdust and boil for 10-20 minutes, scoop out, drain, spread out and air-dry. For every 1.5 kg of dry material, add 500 ml of a mixed solution made from the filtrate containing 0.1% carbendazim and 0.2% monopotassium phosphate, mix well and let cool, then place the culture material on pieces of plastic film of about 0.17 sq m, mix in 40%-50% spawn, crumble and mix thoroughly, pour onto another piece of plastic

Key points to note during the fruiting period of shiitake mushrooms: regulation of temperature and humidity differences
Increase the day-night temperature difference. In late autumn and early winter, daytime temperatures are high and nighttime temperatures are low. Cover with a layer of film during the day so that the temperature inside the mushroom bed is 2°C-3°C higher than outside the film, then open the film after 10 p.m. so the temperature drops rapidly. After several consecutive days, a large number of primordia will emerge on the surface of the mushroom logs and develop into mushroom buds. Control the humidity of the mushroom yard. After color change, initially maintain the relative humidity of the mushroom bed at about 85%. As large numbers of mushroom buds differentiate into caps and stipes, lower the air humidity to about 80%. Create a suitable dry-wet difference. In the early stage of autumn mushrooms, the internal water content of the mushroom logs is relatively sufficient and can safely
