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.

Weather changes trigger acute dehydration and death in rabbits, requiring vigilance
In August 2007, an acute intestinal infectious disease characterized by severe diarrhea, dehydration and rapid death occurred in the breeding rabbit flock of a rex rabbit farm. The incidence rate was about 60%, and the mortality rate reached 40%. Based on epidemiology, clinical symptoms and pathological changes, combined with laboratory testing, it was finally diagnosed as Tyzzer's disease in rex rabbits. The relevant situation is reported as follows. I. Onset process: A rabbit farm raised 1000 rex rabbits, of which more than 200 were breeding rabbits. In early August, after 5 consecutive days of local rain and with the temperature exceeding 3

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

How to prevent mushroom spawn degeneration? Practical control methods
Spawn degeneration can lead to slow mycelial growth, weakened resistance to the environment, contaminant microorganisms and so on, an earlier or delayed fruiting body formation period, and indistinct flushes of mushrooms. There are many causes of spawn degeneration, among which impure spawn and gene mutation are the main reasons; in addition, excessively high temperatures and mixed cultivation of different strains can all cause spawn degeneration. Measures to prevent spawn degeneration include: ensuring pure culture of the spawn, taking care not to use spawn contaminated by foreign microorganisms, and not cultivating in close proximity connected to each other; strictly controlling the number of subcultures, reducing mechanical damage,

How to prevent rabbit breed degeneration? Master these practical methods
Causes of degeneration: Extensive management and inbreeding. Only emphasizing the rabbit's trait of eating grass without supplementing with concentrated feed causes nutritional deficiency and breed degeneration. Ignoring the blood relationship of breeding rabbits and mating closely related animals causes poor disease resistance in offspring rabbits, slow growth, smaller body size, deformities, and breed degeneration. Lack of strict selection measures: not paying attention to selecting and retaining breeding rabbits according to breed characteristic requirements, often selling off the large, fast-growing, well-conditioned ones first and keeping the small, thin, weak ones to continue raising, causing gradual breed degeneration. Mating

Precautions for Deep Plowing and Soil Maturation in Plum and Apricot Orchards
The issues to note during deep plowing are: after deep plowing, water must be applied immediately so that the soil and roots are closely integrated, otherwise drought damage is likely to occur. In orchards on river beach land, if there is a clay pan layer formed by yellow silt soil or gumbo in the lower layer, this layer must be broken through during deep plowing, otherwise a false high water table is likely to form during the rainy season, and it is also unfavorable for root expansion. The depth of deep plowing should vary according to soil texture. Heavy clay soil should be plowed deeply, and sand and organic fertilizer should be mixed in when backfilling; sandy soil should be plowed shallowly, but if the lower layer is semi-weathered rock (crisp stone), then it should be plowed deeply to thicken the soil

Key Technical Points for Site Selection and Land Preparation in Honeysuckle Cultivation
(1) For the seedling nursery, it is advisable to choose sandy loam soil close to a water source, convenient for irrigation, loose and fertile, and well-drained. After selecting the site, plow the soil deeper than 30 cm, harrow it fine and level it, and apply 1500-2000 kg of decomposed barnyard manure or compost per 667 sq m as base fertilizer. Then shallow plow and harrow once, and form beds 100-200 cm wide and 20 cm high. Use these as seedbeds for cutting propagation and sowing propagation. (2) For the planting site, use wasteland slopes, field edges, ditch edges, and in front of and behind houses

What are the methods for keeping shiitake mushrooms fresh with sealed packaging and refrigeration?
There are many methods for keeping shiitake mushrooms fresh, including quick freezing, refrigeration, chemical treatment, controlled atmosphere, and microwaving. Shiitake mushrooms to be kept fresh by dehydration and refrigeration should stop being sprayed with water 10 hours before harvest and be harvested when they reach eight-tenths maturity. After harvest, select them and remove impurities, cut off the mushroom stems, grade them according to customer requirements, then place the shiitake mushrooms on a mat with the gills facing down and dry them in sunlight. In autumn and spring, dry them for 3-4 hours; in summer, dry them for 1-1.5 hours. After drying, the dehydration rate of the shiitake mushrooms is 25%-30%, that is, 100 kg of fresh shiitake mushrooms becomes 70-75 kg after drying. At this point, when pinched
