How to prevent diseases in oyster mushroom wall cultivation? Remember these five points
Disinfection treatment of the fill soil When cultivating oyster mushrooms in walls, the fill soil must be clean soil and must be disinfected before use. Two kinds of fill soil should be prepared: one for sealing the edges, for which soil with greater stickiness should be chosen to prevent the mushroom wall from leaking water; the other for internal filling, for which fertile garden soil should be chosen. Whichever kind of soil is used, it must be dug from more than 10 cm below the ground surface and sun-dried for 3-4 days, then mixed evenly with 1% lime and 0.1% carbendazim for disinfection; for the nutrient soil used as internal filling, add an additional 0.5% phosphate fertilizer

How to keep oyster mushrooms fresh? Introduction to five common preservation methods
Fresh storage: Fresh oyster mushrooms picked after harvest are difficult to sell in the short term due to market influences, so the fresh storage method can be used. The storage time of fresh oyster mushrooms at room temperature is greatly affected by temperature and air humidity. When the room temperature is 3°C to 5°C and the relative air humidity is around 80%, fresh mushrooms can be stored for one week. When the quantity of mushrooms is small, the oyster mushrooms can be placed in a jar containing a small amount of cold water and the jar mouth sealed tightly; even if the temperature reaches 15°C to 16°C, they can be stored for about one week. The oyster mushrooms can also be completely immersed in cold water, but the water must be clean and hygienic, and the iron content of the water should be less than 2 milligrams per liter

How Should Garlic Be Stored? Five New Methods to Teach You
There are many methods for storing garlic. Depending on the storage purpose and conditions, methods such as hanging storage, heap storage, burial storage, radiation storage, and chemical treatment storage can be used. They are specifically introduced as follows. 1. Hanging storage method: When harvesting garlic, the garlic intended for hanging storage should be strictly selected, removing those heads that are too small, have rotten stems and leaves, are damaged, or have been affected by moisture. Then spread them on the ground to dry in the sun until the stems and leaves become soft and yellow, and the outer skin of the garlic is dry. Finally, select 50 to 100 garlic heads of uniform size, braid them, and hang them under a cool, ventilated, rain-sheltered eave so they are air-dried and stored.

How to kill scarab beetles? Five effective control methods
The larvae of scarab beetles, commonly known as chicken-manure grubs, gnaw at the roots of seedlings. Besides biting through lateral roots and the main root, they can also strip and devour the root bark completely, causing missing seedlings and broken rows, and in severe cases even disastrous damage. Adult scarab beetles feed on both leaves and flowers, and they reproduce extremely quickly, so they can easily harm seedlings. They are a common major pest in forestry. The period when adults cause rampant damage is roughly from June to October, and this is the best time for control: it both controls the damage caused by adults and keeps the next generation's population density in check, yielding twice the result with half the effort.

Getting the five key steps right in Gastrodia elata cultivation can effectively increase yield
To achieve stable and high yields of Gastrodia elata, the first thing is to get the five pre-planting steps right: First, choose the site. Gastrodia elata cultivation can be adapted to local conditions, whether indoors, in air-raid shelters, semi-basements, or chicken coops. Because Gastrodia elata likes dark, damp, and cool environments, choose places with good ventilation and shade as much as possible, with semi-basements and outdoor trenches giving the best results. You can lay a layer of bricks before use, or increase the thickness of the bottom sand layer to enhance its water permeability. Second, if the indoor floor is concrete, use high-quality Armillaria mellea fungal material (spawn). Armillaria mellea fungal material

What are the pond-clearing methods? Remember these five before stocking fish fry
Before stocking fish fry, the aquaculture pond must be cleared to kill various predatory small wild trash fish, harmful aquatic animals and plants, parasite eggs, pathogenic bacteria, etc., creating a good environment for the growth of adult fish. The following five pond-clearing methods are introduced: 1. Clearing the pond with quicklime. When carrying out drainage pond clearing (that is, draining the pond water to a depth of 5-10 cm of remaining water before clearing), use 60-70 kg of quicklime per mu of pond; when clearing without draining, use 125-150 kg per mu of pond for every meter of water depth (200 ppm).

Five key measures for cotton seedling stage management
Cotton takes about one month from emergence to squaring, which is a single vegetative growth stage and an important growth period for promoting deep root penetration, preventing seedling diseases, promoting early development, and thereby achieving early squaring. Field management of plastic-film cotton mainly includes: timely releasing seedlings, intertillage and loosening soil, checking and replanting seedlings, disease and pest control, thinning and final thinning, etc. Cotton farmers everywhere have a lot of experience in cotton seedling stage management, which is worth promoting, and is summarized as follows: release seedlings early, seal holes late. When 50% of cotton seedlings have emerged and the cotyledons have flattened and turned green, the seedlings can be released in batches. Release seedlings

How can the efficacy of fishery drugs be improved? Master these five methods
Improve the binder The binder must be highly sticky, otherwise the drug will easily disperse and be lost in the water. Standard wheat flour is a relatively good binder material. For swallowing fish, it is best to make pelleted medicated bait or ball-shaped medicated bait for feeding. Add a feeding attractant Fish have a keen sense of smell; even if 1 gram of alanine is dissolved in 1 million liters of water, fish can still detect it. For example, if strongly aromatic Chinese herbal medicines such as star anise and Angelica dahurica are ground into fine powder to make a feeding attractant, and mixed into fishery drugs at a ratio of 10%-20%, or added to roasted soybean powder, wheat flour, etc., all have obvious feeding-attractant effects
