What are the methods for killing foxes and removing their pelts?
For foxes raised for commercial use, when their fur is mature they should all be killed and skinned, and the raw pelts given preliminary processing. Foxes are relatively large in body size, so the method of killing mink by breaking the neck vertebrae cannot be used. Fox farms in various places have worked out several practical methods for killing foxes, mainly the drug method, the heart air injection method and the electric shock method. Whichever method is used, the principles are that the operation must be simple and practical, the killing must be quick, the pelt must not be damaged, and the fur must not be soiled. 1. Drug method: the drug used is succinylcholine chloride

How to Skillfully Master the Pig Feed-to-Water Ratio? A Must-Read for Pig Farmers
Mixing pig feed with too much water and making it too thin is a long-standing habit among rural people. It has many drawbacks: First, when the feed is mixed too thin, the water content in the daily ration increases relatively, the nutritional components are insufficient, saliva secretion is greatly reduced, the gastric juice is diluted, and the feed stays in the stomach for a shorter time, severely reducing the feed's utilization rate. Second, it increases the physiological burden and raises the body's heat consumption. In addition, in autumn and winter, because pigs urinate more, the pigpen becomes damp and cold, seriously affecting the pigs' growth, development and health. It can thus be seen that pig feed is better prepared as a moist mash, which not only saves

A Detailed Explanation of the Origin and Development History of Black Tea ⟧2⟧Black tea originated in the Ming Dynasty in the 16th century. During the tea manufacturing process, it was discovered that sun-drying could replace the fixing (kill-green) step
Black tea originated in the Ming Dynasty in the 16th century. During tea manufacturing, it was discovered that sun-drying could replace fixation (kill-green), and after rolling the leaves turned red, thus producing black tea. The earliest black tea production began with Souchong black tea in Chong'an, Fujian. In the Qing Dynasty, Liu Jing's "Pian Ke Yu Xian Ji" records: "At the ninth bend of the mountain there is Xingcun town, where tea experts gather. Tea produced elsewhere in the province such as Shaowu and Jiangxi Guangxin, with black leaves and red soup, locally called Jiangxi Wu, is all privately sold to the various firms of Xingcun." After the appearance of Xingcun Souchong black tea, Congou black tea gradually evolved. In the 1920s, India crushed tea leaves during processing to make broken black tea, and in the 1950s our country also began trial production of broken black tea.

Earthing up ginger requires attention to technique; master the skills for a steady high yield
Earthing up is an important measure that determines ginger yield and quality. Only with proper earthing up can ginger grow vigorously and yield high. The rhizome of ginger needs to grow in a dark, moist environment, and stops growing when exposed to light. Therefore, earthing up should be carried out as the ginger grows. If earthing up is not done in time, the ginger rhizome becomes exposed to the air, which seriously affects ginger quality and yield. What methods should be mastered for earthing up ginger? How should earthing up be carried out to better promote rhizome expansion and increase yield? Li

Methods for Skillfully Applying Foliar Fertilizer to Tea Plants to Improve Quality
If famous tea is contaminated, especially export products, its output value and reputation will suffer serious damage. To improve tea quality and yield, in addition to measures such as growing green manure in tea gardens, mulching to retain moisture, applying sufficient farmyard manure after each harvest, and improving tea-making techniques, foliar fertilizer should also be used skillfully. This is a good method that uses a small amount of fertilizer, takes effect quickly, and yields high returns, generally increasing yield by 20%-30% or more. The techniques are: Fertilization timing. When the new shoots of each round of tea in spring, summer, and autumn sprout and grow to the stage of one bud and one initial leaf, choose a windless sunny day at early morning, evening, or on a cloudy day for spraying, once a week for 2-3 consecutive sprays. Spray until water drips from the leaf surface. Fertilizer ratio. Mainly nitrogen, phosphorus, and potassium, supplemented by micronutrient fertilizers, with a ratio of 4:1:1. Micronutrient fertilizers are proportioned according to the principle of supplementing whatever the tea plant lacks. Fertilization concentration. The fertilization concentration is related to the fertilizer variety and weather conditions. According to experiments, urea is 0.5%, superphosphate 1%, potassium sulfate 0.5%, zinc sulfate 50-100 ppm, and ferric molybdate 20-50 ppm. If the concentration is too high, fertilizer damage is likely to occur; otherwise, it will not be effective. Combination with multiple substances. It can be combined with pest control, sprinkler irrigation, and plant growth regulators, saving labor and making mechanized operation easier to achieve. Chemical properties of fertilizers and pesticides. Acidic fertilizers should be combined with acidic pesticides, and alkaline fertilizers with alkaline pesticides, so as not to produce chemical reactions or precipitates, preventing mutual cancellation of fertilizer and pesticide efficacy. Use biological pesticides to control pests and diseases. Using biological pesticides to control tea plant pests and diseases is the best choice, as it is safe, reliable, pollution-free, and harmless, with low cost and high control efficacy, such as Bt emulsion, Bacillus thuringiensis, Beauveria bassiana, agricultural antibiotics, and plant antibiotics.

How to skillfully manage late-season wheat? These technical points must be mastered
Ensure sufficient soil moisture and base fertilizer. For late-season wheat, never rush to sow by seizing moisture; on the premise of ensuring adequate soil moisture, apply heavy base fertilizer, and where conditions permit, apply 3-5 cubic meters of high-quality farmyard manure per mu; at the same time, according to yield requirements, mix 2/3 of the total nitrogen, phosphorus and potassium chemical fertilizers invested throughout the growth period with farmyard manure, spread them on the surface and plow them into the soil. Choose the right variety and increase the seeding rate. Late-season wheat is suitable for semi-winter varieties, which can be selected according to local conditions. At the same time, determine the actual number of days of late sowing according to local autumn temperatures. Generally, it is advisable to increase the seeding rate by 0.5 kg for each day of delayed sowing, and never
