What Types of Physiological Deformities Occur in Mushrooms? A Full Analysis of Common Types
Mushroom deformities are mostly triggered by temperature differences or unfavorable environmental conditions; they may also be related to the strain used. The common deformed mushrooms mainly include the following types: 1. Hollow stipe. From the outside the mushroom looks normal, but when the base is cut off, part of the stipe is found to be hollow, usually with a ring-shaped cavity around a hard core. Afterwards, the cut surface of the stipe may split and curl backward, making the mushroom poor in appearance and reducing its marketability. Cause: This is mainly caused by low air humidity during the fruiting period, rapid evaporation of water from the mushroom body, and overly dry casing soil,

Analysis of Issues in the Formulation and Use of Complete Feed for Ussuri Raccoon Dogs
The raccoon dog is an animal endemic to East Asia, mainly found in China, Russia, Korea, Japan, Mongolia and other countries, and is divided into many subspecies. The Ussuri raccoon dog is mainly distributed in China's Heilongjiang Province, the eastern and southeastern regions of Jilin Province, and northeastern Korea. At present, the vast majority of raccoon dogs bred in captivity in China are Ussuri raccoon dogs originating from Heilongjiang Province. The raccoon dog is one of the fur-bearing animals with high economic value. Compared with foxes and mink, it has the advantages of bearing more cubs, a high survival rate, being easy to raise, and having a stable market; therefore, in recent years the number of raccoon dogs raised in China has steadily increased year by year, with good momentum

How does the large-seeded, high-yielding Huayou No. 5 soybean perform?
On September 30, right in the harvest season for field crops, the reporter saw in the contiguous fields of Huayou No. 5 soybean planted in Gongjiazhuang Village, Qiaoxi District, Shijiazhuang City: the golden leaves could no longer hide the pods covering the plants, the pods hanging on the stems were as densely packed as harvested corn wrapped around tree trunks, the plump beans seemed about to burst the pods, and the 3 seeds in each pod refused to be outdone, each growing perfectly round. Wang Yuling, the breeder of this variety and director of the Soybean Office of the Shijiazhuang Academy of Agriculture and Forestry Sciences, who was conducting a survey in the field, introduced that Gongjiazhuang Village has 1

Cause analysis and preventive measures for deformed mushrooms
In mushroom cultivation, the following deformed mushrooms occur at a relatively high rate. The causes and preventive measures are as follows: The "landmine mushroom" is caused by excessive ventilation of the mushroom house after the coarse soil particles are sprayed wet, low temperature, too late covering with fine soil, and overly wet fine soil particles, which make the primordia of the fruiting bodies attach too low; during the growth of the primordia, they are squeezed by the surrounding soil particles, so the mushroom shape is not round and the surface carries soil, resembling a "landmine." The preventive method is to strengthen water management; coarse and fine soil should be sprayed wet at the right time and slowly; after the coarse soil particles are sprayed wet, reduce ventilation and maintain the relative air humidity in the house at about 80%

Detailed Explanation of Key Techniques for Uniform Planting and High-Yield Cultivation of Soybeans
1. Determine planting density, row spacing and plant spacing according to varietal plant-type traits, branching and other characteristics. (1) Short-stalked, early-maturing, main-stem-type varieties resistant to lodging and branching: row spacing 30-40 cm, plant spacing 8-10 cm, retained seedling density 18,000-25,000 plants. 2. Determine planting density according to soil fertility level and management level at the plant spacing. After determining the planting row spacing according to the variety, density adjustment should also be made according to soil fertility conditions and water-fertilizer management level. 3. Sufficient soil moisture and early sowing. Early sowing can significantly increase yield and increase fat content
