Detailed Explanation of Lily Propagation Techniques: Common Methods and Key Operation Points
Mainly propagated by scales, bulbs and bulbils. I. Cultivating seed bulbs (1) Scale propagation When lily leaves begin to turn yellow in autumn, select robust disease-free plants, dig up the bulbs, cut off the base to separate the scales, take the inner-layer scales, and from September to October on prepared beds, open furrows and plant them at a plant spacing of 3 cm and a row spacing of 17 cm, cover with 3 cm of soil, and cover with grass to preserve moisture. After planting, small bulbs grow from the cut surface, develop into new plants in the spring of the 2nd year, and in autumn are either transplanted for final planting or continuously cultivated for 3 years; the large ones are dug up for

Key Points and Detailed Operation Methods of Lily Whitening Processing Technology
Lily is one of the important health vegetables. The traditional processing method is to blanch the harvested lily and then dry it in the sun. Lily dried by this method still has a relatively high moisture content, is not resistant to storage, and is prone to discoloration. In the past, people used sulfur fumigation to maintain the whiteness of lily, but lily processed by this method is harmful to people's health. Now the dehydration method is used to dry lily, the moisture content is low, and after color protection, blanching and dehydration, discoloration is not likely to occur, which better solves the quality and safety problem of lily caused by sulfur fumigation.

Detailed Explanation and Operation Methods of Pig Castration Techniques
Pig castration is one of the castration techniques for various livestock, poultry and pets. It occupies an important position in veterinary surgery and is an indispensable technique in pig production. Here a brief explanation of pig castration techniques is provided. The principle and purpose of pig castration: the ancients called the testis "shi", so removing the testis of male livestock is also called desexing, and this term has been used to this day. Of course, the castration of livestock and poultry includes not only male livestock and poultry but also female livestock and poultry. Castration of livestock and poultry is the removal of the reproductive glands of livestock and poultry, that is, the removal of the testis or ovary. Castration

Detailed Explanation of Processing Techniques and Operation Methods for Deer Tail
Deer tail is composed of caudal vertebrae, cavity, muscle fibers, adipose tissue, caudal gland, connective tissue capsule and skin. Due to different deer species, its shape and size also vary. The red deer tail is thick and plump, relatively short and wide, with a bluntly rounded tip, making it a superior quality product among deer tails; while the sika deer tail is relatively long and cone-shaped. The female deer tail is relatively short and thick, while the male deer tail is relatively long. Deer tail has been used as a precious tonic and strengthening agent since ancient times in China, and is also a very delicious delicacy. Traditional Chinese medicine holds that deer tail has the effects of benefiting essence, supplementing deficiency, and nourishing and strengthening yang.

What are the specific operation methods for broodstock rearing ponds?
The daily operations of the managers in the rearing pond directly affect the feeding of the broodstock and the success or failure of the rearing. Because the large yellow croaker is very timid and easily startled, the sounds made by managers walking around in the rearing room, feeding, handling tools, and so on, as well as the sudden change in lighting caused by opening the door, may cause the large yellow croaker to temporarily stop feeding or feed less, and may cause it to swim wildly and dash about, so that it hits the pond wall or jumps out of the pond, causing injury or death and affecting the normal development of the broodstock's gonads.

Processing operation key points and quality control methods for mackerel and Spanish mackerel
Mackerel and Spanish mackerel are rich in nutritional value, with DHA and EPA content second only to tuna, and can enhance the body's immunity. They are also very low in price and are well received by consumers at home and abroad. However, mackerel and Spanish mackerel contain a relatively high amount of histidine. When the fish is not fresh or has spoiled, after the action of decarboxylase produced by bacteria, histidine is decarboxylated to produce histamine. When histamine accumulates to a certain amount, there is a risk of poisoning after human consumption. Therefore, process conditions must be strictly controlled during processing to ensure product quality. 1. Processing operation key points

What precautions should be taken when processing snake venom? A full breakdown of the key operational points
1. Pay attention to safety when extracting and processing snake venom. To strictly prevent venomous snakes from injuring people, the movements for releasing the snake during and after venom extraction must be quick. When returning a snake that has been milked to its cage, first place the snake's body inside, and when the snake's head approaches the edge of the container opening, let go quickly. If you cannot withdraw your hand in time when releasing the snake, you can easily be bitten by the snake striking back. 2. Venom extraction equipment must be strictly sterilized. 3. If the venomous snake clamps onto the vessel and will not let go, you may gently swing the snake's trunk; if it still will not release its bite, you may gently twist its neck, or use a small stick or your finger to stimulate the snake's cloaca. Never pull hard

Detailed explanation of large icefish processing technology, mastering the key operation points
Large icefish, also called noodle fish, was originally widely distributed in the main stream and affiliated lakes of the middle and lower reaches of the Yangtze River. Its flesh is tender and delicious, rich in nutrients, and eating it gives a special fresh cucumber-like aroma. Large icefish generally has a body length of about 20 cm, with no bones or spines, and is a small valuable fish with very high economic value, deeply welcomed in domestic and international markets. From 1985 to the early 1990s, the reservoir transplantation and propagation of large icefish was carried out comprehensively across our country and achieved success. Its distribution area is continuously expanding, and output is increasing day by day. How to do a good job in

Key Technical Points for the Early-Stage Operation of Edible Mushroom Growing Substrate
Preparing a good edible mushroom growing substrate is very important, as it directly affects the growth of the edible mushrooms and the grower's returns. Here I will use the preparation of growing substrate with Jinbaobei fermentation agent as an example to introduce the key operating points. 1. Material preparation: Prepare Jinbaobei edible mushroom substrate fermentation aid at 0.1% of the substrate weight (that is, one part per thousand; if discarded substrate is being reused, it may be added at 0.2%); pre-soak or rinse the crushed or cut main material in advance to pre-wet it, and adjust the moisture to 60-70% and the pH to about 8. If the moisture is too low, it is not conducive to the rapid reproduction of functional microorganisms,

Detailed explanation of the specific operation techniques for flower and fruit thinning in pear trees
1. Master the timing of flower and fruit thinning. Flowering, fruit set, and the number of cells in young fruit are mostly determined by stored nutrients. Remove as many excess flowers and fruits as possible to reduce wasteful consumption and concentrate all nutrients on the flowers and fruits that should be retained, so they can grow into large fruits. Therefore, from this reasoning, earlier thinning is better: thinning flower buds is better than thinning flowers, and thinning flowers is better than thinning fruits. However, decide whether to thin buds, thin flowers, thin fruits, or combine all three according to the year's flower quantity, weather during the flowering period, tree vigor, fruit-setting ability, and other conditions. For pear orchards with a large flower quantity (an "on" year), good weather, and a heavy workload, you can
