Scientific use of chemical control technology in cotton can effectively increase yield
Scientific chemical control of cotton is an important scientific measure for increasing cotton yield. Chemical regulation technology has three benefits: first, it helps strong seedlings to develop early, controls height and stabilizes growth, making it easier to give play to the yield-increasing advantage; second, it simplifies cotton field management, saving labor and cost; third, it promotes the transformation of second- and third-grade cotton seedlings, achieving balanced development and increasing yield and efficiency. The principle of chemical control is "small amounts, many times; light control, frequent adjustment." One should master "spray every time, control every time" or "control once at every interval" (flexibly according to soil fertility, rainfall, and growth condition), and it is best to "divide the amount for one application into three applications," ensuring the plant grows steadily and robustly "strong but not excessive" from beginning to end. If chemical control is done poorly, it can cause excessive growth or stiff seedlings that do not develop, affecting the normal growth of cotton. Therefore, in the process of implementing chemical control, the dosage of the chemical control agent must be strictly controlled.

Sexual propagation proves effective for gastrodia cultivation
Gastrodia is a flagship product among the traditional Chinese medicinal herbs of our province. As the quality of gastrodia cultivation degrades year by year and diseases become severe, gastrodia yields are low and returns are poor. How to solve this problem? Experts at the Fengcheng City Yulong Sexual Seed Propagation Demonstration Service Base have found a way: with the method of sexual propagation of gastrodia, not only do yields increase by 2-3 times compared with asexually propagated gastrodia, but the disease resistance of gastrodia is also greatly enhanced. What is sexual propagation of gastrodia? According to Mo Bingyao, an expert at the Fengcheng City Yulong Sexual Seed Propagation Demonstration Service Base, gastrodia cultivation in our province basically all uses

A Highly Effective Method of Using Mirabilite to Treat Pig Eczema
Eczema is a skin disease that occurs frequently in pigs in autumn. Acute and chronic eczema has the main symptoms of erythema, papules, and itching on the skin, and a few cases are accompanied by pustules, exudate, erosion, and scabbing, and it is especially harmful to suckling piglets. Based on practical experience in production, treatment with mirabilite has a highly effective result. Method: according to the size of the pig and the area of the affected part, take 50-200 grams of mirabilite respectively, add 200-500 milliliters of cold boiled water, and after dissolving, apply and rub the affected part, 4-5 times a day, or use a clean towel to dip the liquid and wipe the affected area, for half an hour each day,

Effective prevention and treatment methods for reproductive stress in breeding sows
1. Symptoms: (1) Abnormal bone metabolism, weak limbs and hooves, abnormal limb morphology and gait. Soft feet, hoof cracks, hemorrhage under the hoof shell, and in severe cases postpartum paralysis. (2) Sows show reproductive disorders, especially first-litter sows, with delayed estrus, anestrus or failure to come into estrus. More piglets born in the first litter, fewer in the second; or more in one litter and fewer in the next. Sows have weak disease resistance, reduced immune function, incomplete uterine involution, increased incidence of endometritis and mastitis, and are prone to various infections, with a higher culling rate. (3) Sow fertility and pig

How to treat swine asthma? Sharing effective remedies and new methods
Swine asthma is a chronic disease characterized mainly by coughing and wheezing, accelerated breathing, audible wheezing sounds, a dog-sitting posture, foamy discharge from the mouth and nose, and reduced appetite, and it mostly occurs in cold, damp weather or when the climate changes abruptly. Affected by feeding management and sanitary conditions, the mortality rate is relatively high when secondary infection occurs. The following combination of drugs can cure it in a very short time, with good results. The method is: inject 1 ml of Houttuynia cordata injection and 10 ml of ciprofloxacin hydrochloride injection per kilogram of pig body weight, and inject 5-10 ml of methylene blue injection and 0.01-0.03 ml of atropine sulfate injection per pig, all by intramuscular injection, twice a day, with 4 days as one course of treatment, and two courses for severely ill pigs.

Tea plants are prone to banjhi (dormant buds) after autumn, so effective prevention and control are very important
Banjhi in tea plants refers to the phenomenon where tea buds are slow to grow, or bud break is delayed with a low sprouting rate and the new shoots produced are rather small. When tea plants are in the banjhi state, it is extremely favorable for flower bud differentiation, causing the tea plants to produce a large number of tea flowers from late October to mid-November, which consumes a great deal of nutrients, directly affects the growth of tea leaves the following year, and accelerates the aging of the plant. Therefore, preventing banjhi in tea plants is very important. To prevent banjhi in tea plants, the tea garden soil should be fully tilled 3-5cm deep in summer and autumn, so as to cut the soil capillaries and

How can reproductive disorders in pigs be effectively reduced?
Reducing reproductive disorders in pigs: 1. Breeding healthy boars and sows: First, through vaccination or medication prevention, ensure that boars and sows are not troubled by diseases, especially the prevention of pseudorabies, swine fever, parvovirus, Japanese encephalitis, as well as infectious diseases such as chlamydia and eperythrozoonosis. Second, manage boars and sows well by stages, that is, reserve boars and sows, pregnant sows, farrowing sows, open sows, young boars, mature boars, etc., should all be cared for according to their respective characteristics and needs. Third, the prevention and treatment of limb and hoof diseases in boars and sows, and mastitis and metritis in farrowing sows.

How to effectively prevent and control contaminating fungi in Gastrodia elata cultivation
1. When cultivating fungal wood, carefully inspect the fungal branches and fungal logs. Contaminating fungi prefer saprophytic life, so fresh wood that is not decayed and free of mold should be selected for cultivating fungal logs, and the cultivation time should be shortened as much as possible. If contaminating fungi are found on the fungal logs, scrape them off if the infection is light and sun-dry for 1-2 days; discard them if the infection is severe. 2. Inspect the Gastrodia elata seeds used. If mold infection is found, scrape it off and sun-dry if the infection is light, or disinfect the affected area locally with 75% alcohol, carbendazim, etc. before use. Any Gastrodia elata seeds that are bruised or rotten must be discarded. 3. The filling material must be packed firmly, and never leave

How to effectively prevent browning after harvesting lilies?
During the harvesting and storage of lilies, due to prolonged exposure to sunlight, the color of lily scales changes from white to brown, a condition known as browning. Browning is an oxidation reaction that occurs under the catalytic action of biological enzymes in lily scales. Browning reduces the quality of commercial lilies; if they are seed lilies, the germination rate of browned bulbs is low, causing seed rot. This year lilies matured early, and harvesting is expected around early July, so attention should be paid to preventing browning early. During harvesting, attention should be paid to shading and covering. Under strong direct sunlight, lilies dug from the soil are often prone to
