How to prevent and treat swine enzootic pneumonia? Pig farmers need to master these methods
The pathogen is Mycoplasma hyopneumoniae. Piglets and suckling pigs are most susceptible, while adult pigs show latent infection without symptoms, mainly reducing productivity. It occurs when stimulated by adverse stress factors, characterized by coughing and panting (abdominal breathing), often secondary to pleuropneumonia, Streptococcus, swine pneumonia, cold, etc. At this point, body temperature rises and symptoms worsen, requiring comprehensive treatment. Prevention and control: 1. Strengthen disinfection. "Minxing Disinfection Star" or "Minxing No. 5 Disinfectant" can be used. Try to achieve self-breeding and self-raising in epidemic prevention work.

How to manage greenhouse apricots? Master these four technical points
1. Fertilizer and water management. Apply base fertilizer every autumn. The base fertilizer is mainly organic fertilizer such as livestock manure, compost, and cake fertilizer, appropriately mixed with some nitrogen, phosphorus, and potassium fertilizers. After covering with plastic film, no more topdressing is applied; after fruit set and during the hard-core stage, spray once with 0.3% urea plus 0.2% compound micronutrient fertilizer and 0.3% monopotassium phosphate. Install drip irrigation pipes in the greenhouse and water reasonably according to soil moisture. Do not water too much, so as to avoid excessive growth of new shoots and cause physiological fruit drop. 2. Training and pruning. For "Y"-shaped training, mainly retain lateral branches (main branch branching angle about 70 degrees

How is Lycoris radiata processed? These processing methods must be mastered
Lycoris radiata mostly grows in shady, damp forest edges, on embankments, in cemeteries, or beside roads. The underground bulb is broadly elliptical or nearly spherical, with a grayish-black outer skin; the linear leaves grow in clusters, dark green on the surface and glaucous green on the underside. The margins are entire; the flowers appear before the leaves, and in autumn a flower stalk emerges from the bulb, bearing several stalked flowers at the top arranged in an umbel. The flowers are bisexual, with large petals that curl backward, usually bright red or with white edges, and no fragrance; the stamens and pistils are very long and protrude beyond the flower. Lycoris radiata can be dug up year-round; when digging, be careful not to bruise the bulb, or it will easily rot. After digging, it is best to process it immediately.

What to Do When Rice Seedlings Suffer Fertilizer Burn? Master the Correct Remedial Methods
Blindly increasing the amount of chemical fertilizer applied will cause various physiological disorders in rice seedlings, making growth and development abnormal after transplanting. Applying excessive amounts of undecomposed organic fertilizer will also cause poor growth of rice. This kind of physiological disorder caused by excessive fertilizer application is "fertilizer burn." 1. Causes of fertilizer burn There are many causes of fertilizer burn in rice seedlings, which can be summarized into three: First, improper fertilization methods. For example, applying ammonia water or ammonium bicarbonate under high temperature at noon, the volatilized ammonia gas causes fumigation damage to rice plants.

How should fishery drugs be used in a standardized way? Master these key points for medication
Fishery drug residues are currently the most common source of contamination in aquatic products. There are many reasons for excessive drug levels in aquatic products, among which the abuse of drugs and feed additives is the main culprit. Standardized medication is a fundamental measure for preventing excessive drug residues in aquatic products, improving the quality of aquatic products and crossing the "green barrier". For this reason, the author discusses how to use fishery drugs in a standardized way from the following aspects, for the reference of the vast number of farmers. 1. Strictly implement national laws and regulations In recent years, relevant departments have successively issued

How to fatten up thin cattle? These fattening techniques must be mastered
1. Selecting thin cattle. Not just any thin cattle can be purchased for fattening. Only thin cattle that have become thin due to poor feeding management, heavy work, and other such reasons can be rapidly fattened through careful feeding and management. Great care must be taken when selecting thin cattle, and one must absolutely avoid purchasing thin cattle that are too old, extremely weak in constitution, or suffering from chronic digestive tract diseases or infectious diseases. 2. Disease prevention and deworming. Newly purchased thin cattle must undergo a comprehensive examination, and only after being vaccinated against foot-and-mouth disease, brucellosis, and Clostridium welchii disease can they be admitted to the barn and mixed with other cattle. Before formally starting

How to scientifically restrict-feed young chickens? Master these technical points
Under normal circumstances, young chickens should be given restricted feeding. In restricted feeding, some chicken raisers believe that the less the chickens eat the better, and the poorer the feed quality the better; therefore, they provide young chickens with a single feed, with no regularity, no plan, and no standard, and manage them carelessly. In fact, this practice misunderstands the original meaning of restricted feeding. The purpose of restricted feeding is to control the chicken's weight gain, prevent the chicken from reaching sexual maturity too early (laying too early), maintain the standard laying start time and body weight, slightly inhibit its growth, and prevent the chicken from increasing body

How to Choose Land for Codonopsis Planting? These Methods Must Be Mastered
Codonopsis is a deep-rooted plant, and mature plants prefer light, so it is best to choose deep, fertile, sunny sandy loam for cultivation. Low-lying, waterlogged, and heavy clay soil is not suitable for cultivation; water accumulation in the soil easily causes root rot, poor aboveground plant growth, and low yield with poor quality. Slightly acidic to neutral soil with a pH of 6.5-7 is preferable. Legume and grass family crops are best as the previous crop; vegetable crops as the previous crop are prone to disease and should not be chosen. Continuous cropping is prohibited, and generally 3-4 years should pass before replanting.

How to Grow Dendrobium Orchids? Mastering These Cultivation Tips Is All You Need
Dendrobium orchids, along with Cattleya, Phalaenopsis and Vanda, are ranked as the four major tropical ornamental orchid groups, and they are one of the largest genera in the orchid family. According to differences in their biological characteristics and ecological requirements, they can be divided into two major categories: deciduous dendrobiums and evergreen dendrobiums. There are many Dendrobium varieties, and those commonly grown for ornamental purposes include Dendrobium densiflorum, Dendrobium thyrsiflorum, Dendrobium phalaenopsis, Dendrobium nobile, Dendrobium primulinum, Dendrobium loddigesii, Dendrobium fragrans and others. Dendrobium flowers are beautiful in shape and form, making them important cut flower and potted plant varieties. To grow Dendrobium orchids well,
