A Detailed Guide to Selecting and Using Fishery Drugs: A Practical Guide for Farmers
When selecting fishery drugs, the "three certificates" must be complete (production license, production approval certificate, execution standard number), and there must be a product quality certificate. Legitimate fishery drug manufacturers have applied for registered trademarks; the trademark design, image, text, etc. are indicated on the packaging, labels, and instructions, and are marked with the words "registered trademark" or a registration mark. The quality of the inner and outer packaging materials of fishery drugs should be good. Generally, the packaging is marked with instructions for use, trade name, chemical name, drug composition, content, production approval number, manufacturer name, address, production batch number, production date, validity period, indications or functions and main treatments,

A Detailed Guide to Using Sacrifice Branches in Stump Bonsai
In the process of creating stump bonsai, branches that are temporarily used at a certain stage to achieve a specific styling goal are called "sacrifice branches." Such branches have broad application value in styling work. 1. Strengthening roots: Although a stump has a root on one side, it is very thin and weak, and is very disproportionate to the roots on the other sides. At this time, if a branch is cultivated above the tree base near this root and kept in a certain vigorous state, it will drive the rapid growth of this nearby root, thereby achieving the styling idea as quickly as possible. After that, the utilized branch can be cut off and trimmed so that no obvious trace remains.

Detailed Explanation of the Open-Field Cultivation Technique for Shiitake Mushrooms Using Substitute Materials
Recently, Gutian County in Fujian Province hosted the National Edible Fungi Technology Market. More than 700 people from research, production and management units as well as specialized household growers from 20 provinces, municipalities and autonomous regions gathered in Gutian. After visiting the county's field-cultivated shiitake mushrooms, everyone praised them without exception. Gutian County uses a new technique for open-field cultivation of shiitake mushrooms with substitute materials, and mushrooms emerge 70-80 days after inoculation. On average, every 100 kg of sawdust or cottonseed hulls can produce 8-12 kg of dried shiitake mushrooms, which is more than 10 times the per-unit yield of the old log cultivation method, and the production cycle has been shortened from the original more than two years to 10 months. The product's shape

Correct methods for using cotton seedling protection agent
I. Methods for using cotton seedling protection agent The cotton seedling protection agent consists of three bags: large, medium and small. The specific seed soaking steps are: 1. Soak 5 kg of cotton seeds in clear water mixed with three parts hot (about 70°C) and one part cold for 5 minutes, remove the cotton seeds and squeeze out excess water. 2. Dissolve the small bag of reagent in 0.5 kg of clear water, pour it into the cotton seeds soaked in the three-hot-one-cold clear water, stirring while pouring, and after thorough stirring leave for 24 hours (stirring 2~3 times during this period). 3. Dissolve the medium bag of reagent in 1.54 kg of clear water, pour it into the cotton seeds soaked with the small bag of reagent

Detailed Explanation of High-Temperature Open-Air Cultivation Technology for Shiitake Mushrooms Using Sawdust
The technology of cultivating shiitake mushrooms (Lentinula edodes) using sawdust as the raw material under high-temperature conditions of 30°C breaks the seasonal restrictions of traditional shiitake cultivation, allowing production in all four seasons. The method is: add water to sawdust and boil for 10-20 minutes, scoop out, drain, spread out and air-dry. For every 1.5 kg of dry material, add 500 ml of a mixed solution made from the filtrate containing 0.1% carbendazim and 0.2% monopotassium phosphate, mix well and let cool, then place the culture material on pieces of plastic film of about 0.17 sq m, mix in 40%-50% spawn, crumble and mix thoroughly, pour onto another piece of plastic

Nine precautions for using fishery drugs in summer
Summer is a period of high incidence of fish diseases, and also a peak period for the use of fishery drugs. The following points should draw everyone's attention: 1. When two drugs are mixed for use, they should first be dissolved separately in water before mixing. Copper sulfate, ferrous sulfate, potassium permanganate, etc. should all be dissolved in water in a wooden bucket or wooden basin. Powdered drugs such as bleaching powder and trichlorfon should first be mixed with a small amount of water into a paste, then diluted with water, so as to prevent caking that may be mistakenly eaten by fish. The following drugs cannot be mixed: bleaching powder and quicklime, copper sulfate and quicklime, trichlorfon and quicklime. 2. Appli

Common Diseases Causing Persistent High Fever in Pigs and Their Prevention and Treatment Methods
(1) Swine fever: The pig's body temperature rises to 40-42°C and does not subside persistently; appetite decreases or the pig stops eating, mental depression, shivering, lying prone and sleepy, huddling together or burrowing into straw; when standing and walking, the back is arched and the waist bent, limbs are weak, movement is slow, gait is unsteady and swaying, conjunctiva is red with purulent discharge, first constipation, then diarrhea; at the base of the ears, abdomen, inner sides of the limbs and other areas there are purplish-red bleeding spots that do not fade under finger pressure. Lesions: systemic lymph nodes are enlarged with peripheral hemorrhage, showing a red-and-white mottled marble-like appearance; the kidneys become pale with pinhead-sized bleeding spots on the surface; the spleen is enlarged and hemorrhagic, with the edge

Comparative Trial of Six Strains in Substitute-Material Cultivation of Lentinula edodes Using Liquid Spawn
In recent years, China's shiitake (Lentinula edodes) production has developed rapidly, with substitute-material cultivation of shiitake being particularly prominent. The traditional solid spawn production technology for shiitake requires a rather cumbersome three-stage process of mother culture, stock culture and cultivation spawn before it can finally be expanded to the production of cultivation bags. Its high labor intensity, cumbersome process, high rate of contaminant mold infection and long growth cycle all greatly restrict the development of shiitake. In this experiment, liquid spawn of 6 shiitake strains was cultured and compared in cultivation, so as to provide a certain theoretical basis for the promotion and application of liquid spawn for shiitake. 1 Materials and Methods 1

What are the precautions for using fungicides during the cotton seedling stage?
1. When choosing a fungicide, first understand the nature of the fungicide. There are two types of fungicides: one is a protective agent, which is used to prevent plants from developing disease, such as Bordeaux mixture, mancozeb, and carbendazim; the other is a therapeutic agent, which is applied after plants have developed disease to kill or inhibit the pathogens that have invaded the plant body. Therapeutic agents work better when applied in the early stages of disease, such as compound fungicides like kangkuening and baozhida. 2. Fungicides should be sprayed before 9 a.m. or after 4 p.m. If sprayed under the scorching sun, the chemicals break down and evaporate easily,
