Detailed Explanation of Mushroom Cylinder Cultivation Technology in Cold Greenhouses (Part 1)
I. Sowing Time: In the Xinbin area, from March 20 to April 10, preferably completed before Qingming Festival. When the temperature inside the greenhouse reaches above 5°C, cylinder production and cultivation can begin. II. Ingredient Mixing and Sterilization. Formula 1: Broadleaf sawdust 87%, wheat bran 8%, rice bran 8%, cornmeal 3%, gypsum 1%, with a moisture content of 58%-62%. Formula 2: Broadleaf sawdust 50 kg, wheat bran 10 kg, gypsum 1 kg, with a moisture content of 58%-62%. 1. Mixing: The mixed material should be sterilized promptly and must not be left for more than 2-3 hours, to avoid the growth of contaminant bacteria that could result in incomplete sterilization.

Extreme potassium deficiency in cotton fields can cause large numbers of plants to die
Cotton is a crop sensitive to potassium deficiency, especially since the development of BT transgenic insect-resistant cotton, potassium-deficient cotton fields often show severe disease, premature aging, few and small bolls, poor boll opening and deteriorated fiber quality. Four or five years ago, rapid soil nutrient tests on cotton fields in central and southern Hebei showed that most soils had available potassium content below 80PPM (mg/kg), which is severe potassium deficiency, and some soils were below 40PPM, reaching the level of extreme potassium deficiency. The data measured by soil nutrient rapid testers is not precise; some soil samples measured available potassium content of 0

Detailed Explanation of the Method for Making Shiitake Mushroom Spawn for Field Cultivation in Greenhouses
After the spawn logs are made, place them in the stove for sterilization, keeping them at 100°C for more than 16 hours. When mixing ingredients according to the conventional formula, absolutely do not reduce any ingredient in the formula. The raw materials should be fresh and free of mold. The inoculation time is early December. Before inoculation, seal the inoculation room and disinfect it with potassium permanganate at 7 grams per cubic meter and formalin at 13 milliliters per cubic meter for 6 hours; inoculation personnel must also be disinfected before entering the inoculation room to inoculate, and inoculation should not be done on rainy days. After inoculation is completed, carry out a second disinfection, then close the doors and windows for 3 days. After 3 days, open

Can distiller's grains be used as a substrate for growing oyster mushrooms?
It is acceptable to use distiller's grains instead of wheat bran as a supplement for producing oyster mushrooms. The usual amount is about 20%, and the other 70-80% can be cottonseed hulls, sawdust, or similar materials. Because distiller's grains are fairly acidic, some lime or similar material should first be mixed in before use, bringing the pH down to 6-6.5.

Method for ridge cultivation of Gastrodia elata in plastic greenhouses
Cultivating Gastrodia elata in ridges inside plastic greenhouses can be done on either a large or small scale, with low investment, high returns, and savings in labor, effort, and arable land. It requires no fertilizer, no pesticide spraying, and no weeding, and delivers significant economic benefits. The technique is described below: 1. Site selection: It is advisable to choose a shady slope or a gentle slope with half shade and half sun, sandy soil with good permeability, and slightly acidic or neutral soil with a pH of 5.5-6.0 for building the site. 2. Greenhouse construction: Follow the construction method for vegetable greenhouses, facing north and south, with the size determined by the scale of Gastrodia elata cultivation, generally 8 m wide and the length depending on the terrain

How to treat rectal prolapse in pigs? Introduction to commonly used therapies
Rectal prolapse in pigs falls into two situations: the first is that the sick pig can retract the prolapsed tissue on its own when standing, but it protrudes again when defecating; the second is that the sick pig cannot retract it on its own when standing. For the latter, surgical treatment is often adopted, with a cure rate of up to 100%. Now, for the first situation, a simple therapy worth promoting is introduced. Use a 0.1-0.2% potassium permanganate solution, while it is still warm, to wash the affected area, dry it with sterile gauze, and apply an appropriate amount of river snail meat paste to the affected area. Preparation of river snail meat paste: wash the river snails, remove the shells and take the meat, use a 0

How to prevent and control red and white plastron disease in soft-shelled turtles? Detailed explanation of causes and prevention methods
Red and white plastron disease in soft-shelled turtles (commonly known as red plastron and white plastron disease) has been a relatively serious turtle disease in China in recent years, and so far there is still no ideal treatment method. However, through efforts in various aspects, the main pathogens and disease onset conditions of red and white plastron disease have basically been identified, and breakthrough progress has been made in prevention, especially in research on disease prevention with Chinese herbal medicines and immune vaccines, laying a foundation for controlling the occurrence of red and white plastron disease in the future. Based on relevant domestic research and my own practice, the author introduces the occurrence and prevention of red and white plastron disease as follows, for reference and application by interested parties.

Key Technical Points for Environmental Control in Greenhouse Lily Cultivation
In lily cultivation, besides having high-quality bulbs, strict control of the growing environment according to the requirements of different varieties throughout the entire growth process is also needed to produce lily products with good plant form and high quality. If conditions are not well controlled, it will not only affect the plant form of the lilies, but in severe cases also affect plant growth, and may even prevent normal flowering. The following briefly introduces environmental control during lily cultivation based on the requirements of lily planting. 1. Greenhouse A good growing environment can ensure the normal growth of lilies.

How to cope with severe weather in winter and spring greenhouse oyster mushroom production?
In winter and spring, severe weather such as snowfall, cold waves, strong winds, prolonged overcast fog, and sustained low temperatures often arrives uninvited. In mild cases it causes reduced oyster mushroom yields and lower quality; in severe cases it causes total crop failure. Therefore, prevention of and response to severe weather should be strengthened. Main preventive measures: wipe the greenhouse film to improve light transmittance; inspect the greenhouse facilities to ensure the greenhouse's insulation performance; prepare insulating and warming items such as straw mats and old greenhouse film. Response management measures: Cold wave and strong wind cooling weather: Before a cold wave and strong winds arrive, seal the vents tightly, cover the greenhouse film securely, and add a layer of intact old plastic film over the straw mats.

Detailed Explanation of Key Techniques for Oyster Mushroom Cultivation in Greenhouses
Oyster mushrooms grow fast, have strong stress resistance, come from a wide range of substrate sources, are easy to cultivate and manage, and can be grown in all four seasons. In our province, greenhouse cultivation is the main method. Through extensive research, the author has compiled the cultivation techniques for greenhouse oyster mushrooms as a reference for fellow farmers. 1. Variety selection: In early spring, medium-temperature varieties should be used; in late spring and early summer, medium- and high-temperature varieties should be used; in summer and autumn, high-temperature varieties should be used. 2. Production season: For medium-temperature varieties, stock spawn is made in November-December, and production spawn is made in January-February; for high-temperature varieties
