What Is a Beehive? A Detailed Introduction to Beehive Basics
1. Structure of a beehive A beehive with movable frames (movable-frame hive) is an important production tool for scientific beekeeping. When movable-frame hives are used for beekeeping, the hive can be opened at any time, the comb can be taken out for inspection, the condition of the colony can be understood, the life activities of the bees can be observed, and various bee products can be produced according to need and possibility; it is also convenient for migratory beekeeping. Beehives are placed in the open air for long periods, exposed to wind, rain, and sun, and the bees must live in the hive, rear brood, and store feed, so the structure of the hive must conform to the living habits of bees, with uniform standard dimensions, and be sturdy and du

Stropharia rugosoannulata: Introduction to a New Edible Mushroom Variety
Stropharia rugosoannulata, also known as the wine-red stropharia. Stropharia rugosoannulata is an edible mushroom cultivated in many European and American countries, and is also one of the edible mushrooms recommended by the Food and Agriculture Organization of the United Nations (FAO) for cultivation in developing countries. Cultivation of Stropharia rugosoannulata started relatively late in China. After trials and demonstration promotion in recent years, it has been cultivated in most regions of the country, but the cultivated quantity is small, and the amount of its products on the market is also very limited. Stropharia rugosoannulata has abundant cultivation materials; it can be cultivated simply by moistening crop straw with water; moreover, it has a wide range of adaptability, and can produce mushrooms within a temperature range of 4°C-30°C, with high yields as well.

An Introduction to a New Rapid Drying Method for Edible Mushrooms
A new rapid drying method for edible mushrooms is introduced below. It can greatly shorten the drying time while ensuring product quality. This method takes only 15 minutes to turn fresh edible mushrooms into dried products, with no loss or change in the nutrition and flavor of the edible mushrooms. It is worth adopting in the edible mushroom processing industry. The new rapid drying method uses a high-pressure room-temperature drying system. Fresh edible mushrooms are placed in a sealed dryer, and a high-pressure dry air stream is immediately introduced, causing the air to circulate within the dryer. Due to the flow of the gas, the moisture in the fresh edible mushrooms

How to increase the yield of edible mushrooms? Introduction to practical methods
1. Scratching method: When the mycelium has covered the surface of the substrate, gently sweep a clean bamboo broom back and forth over the substrate surface to remove or break up the spindly surface mycelium and old mycelium. After new mycelium is exposed, spray water and cover with plastic film to retain moisture and warmth; primordia will appear and mushrooms will fruit in about 7 days, generally increasing the yield by about 10%. 2. Startling method: After the substrate is fully covered with mycelium, press and pat the substrate surface with flexible wooden slats to vibrate it. When doing this, apply force evenly, do not leave deep marks, and do not damage the substrate surface. This can promote accelerated mycelial growth and rapid differentiation of fruiting bodies. This method is suitable for shiitake (Lentinula edodes), oyster mushroom (Pleurotus ostreatus), phoenix mushroom

Introduction to the Cotton "Dong A" Genic Male Sterile Germplasm Resource
In 1972, a male sterile cotton plant was discovered in the field, and after 3 years and 6 seasons of research, the cotton "Dong A" genic male sterile germplasm was successfully developed. Its male sterility trait is mainly controlled by a pair of recessive nuclear genes. It has the characteristics of stable inheritance of male sterility, easy transfer, strong combining ability, a wide range of restorer lines, a population male sterile plant rate of about 50 percent, and 100 percent male sterility per individual plant. It also has good yield potential and wide adaptability. Using the Dong A genic male sterile germplasm, 1 derivative male sterile line was developed. Among them, several derivative male sterile lines were further combined and screened to produce 12 hybrid
