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

Detailed Explanation of the Differences and Origins of Snake Sex Chromosomes
The sex of snakes is determined by sex chromosomes and belongs to the ZZ/ZW mechanism. To study the origin and evolution of snake sex chromosomes, Kazumi Matsubara and other researchers from the Creative Research Initiative Sousei (CRIS) at Hokkaido University in Japan used fluorescence in situ hybridization to measure the four-striped rat snake (Elaphe quadrivirg

What is the difference between Japanese euonymus (Euonymus japonicus) and Jiaodong euonymus (Euonymus kiautschovicus)?
Japanese euonymus and Jiaodong euonymus are evergreen plants of the same genus but different species, both good materials for hedges. The leaves of both are leathery, and there is no obvious difference in leaf shape, so many people lump them together. The main differences between the two are described below: 1. Plant form. Japanese euonymus has a compact form, the branches are relatively upright, and the natural branching point of the side branches is relatively high; Jiaodong euonymus has a loose form, the natural branching point of the side branches is relatively low, and the branches at the base are prostrate and can take root. 2. Leaves. Although the leaves of both are leathery, the fine serrations on the leaf margin of Japanese euonymus are more

What is the difference between ordinary Gastrodia elata and "Mingtianma"? Are they two different varieties?
After harvesting Gastrodia elata, select those that are large, uniform, and have a red "parrot's beak," wash them in water, peel them, boil them (adding alum water), shape them, dry them, and then fumigate them with sulfur; in this way the color is good, and through this fine processing "Mingtianma" is made. Most of those supplied for export are called Mingtianma. Gastrodia elata and Mingtianma are the same variety; the only difference is that the processing is coarse or fine.

Do different cotton varieties require different fertilization methods, and what are the similarities and differences?
Recently, when the author visited cotton-producing areas in counties and cities such as Tianmen, Hanchuan, Jingshan, and Jianli, as well as Huarong, Anxiang, and Nanxian in Hunan Province, many farmers asked about cotton fertilization techniques. They often regard fertilization as one of the important means of increasing yield, so they show great concern about fertilization techniques. Years of experience and lessons in cotton fertilization tell us that the common experience for increasing cotton yield through fertilization is: apply sufficient basal fertilizer, apply seedling fertilizer quickly, apply bud fertilizer steadily, apply flower and boll fertilizer heavily, and apply boll fertilizer universally. However, when it comes to different cotton varieties, there are differences in fertilizer application.

Differences Between Three Soft-Shelled Turtle Diseases and Their Prevention and Treatment Methods
In the process of soft-shelled turtle farming, some farmers cannot clearly distinguish white spot disease, white spot fungus disease and saprolegniasis, and blindly and indiscriminately use drugs when treating turtle diseases, thus affecting the effectiveness of disease prevention and treatment. Therefore, based on recent years of practice at soft-shelled turtle farms, the author summarizes the differences between the above diseases and comprehensive prevention and treatment methods as follows. I. Differences between white spot disease, white spot fungus disease and saprolegniasis in soft-shelled turtles 1. Different pathogens: the pathogen of white spot disease is Aeromonas hydrophila, Aeromonas sobria, etc.; the pathogen of white spot fungus disease is Mucor, which belongs to

Differences Between Fowl Plague and Fowl Cholera and How to Tell Them Apart
When fowl cholera is epidemic, chickens, ducks and geese often become ill and die at the same time, whereas Newcastle disease affects only chickens. Symptoms: In acute cases of fowl cholera the crop is full of food, whereas in Newcastle disease it is full of gas and fluid; chronic cases show nervous symptoms such as a twisted head and neck, while fowl cholera has no nervous symptoms and a short course. Necropsy: In fowl cholera a large amount of pale yellow fluid accumulates in the pericardial sac, with hemorrhage on the epicardium and grayish-white necrotic spots on the surface of the liver, and yellow caseous exudate is often found on the surface of the air sacs and intestines; whereas in Newcastle disease the liver has no necrotic spots,
