Jing'an in Jiangxi Successfully Cultivates the World's Rare White Tea
Recently, the world's rare tea variety -- white tea -- was successfully cultivated through stem cuttings in the experimental garden of the tea factory in Luowan Township, Jing'an County, Jiangxi Province. White tea is one of the world's rare and precious teas, belonging to the asexual, fruitless cultivated plant species. On the international market, 1 kilogram of white tea sells for as much as 5,000 yuan RMB, giving it relatively high economic value, but very few regions in our country produce white tea. According to Zheng Guangshui, who is responsible for white tea production management in Luowan Township, Jing'an County, the former Shijing Tea Factory in Jing'an County successfully introduced and transplanted 40 mu of white tea in 2000.

How to raise pullets for egg production successfully? Detailed explanation of key technical measures
When chicks are 7 weeks old, they are moved into the growing house and enter the growing stage. Whether this stage is successful or not largely determines the physique and laying performance of laying hens after sexual maturity. Therefore, to raise high-yielding replacement laying hens that meet breed requirements, the key link is to do a good job in the feeding and management of growing chickens. 1. Do a good job in disinfecting the environment inside and outside the chicken house to create a relatively safe living environment for the flock. Many diseases on laying hen farms are caused by horizontal transmission. Therefore, disinfecting the chicken house, the surrounding environment, and the chickens themselves to cut off the links of horizontal disease transmission is an effective way to control disease occurrence and reduce chicken deaths. The specific technical measures taken are: ① Two weeks before introducing the chickens, first thoroughly clean and wash the chicken house, then wash and disinfect it with disinfectants such as Baidusha or Aidifu. ② Use formalin plus potassium permanganate for fumigation disinfection at a ratio of 30 ml plus 15 g, keep it sealed for 1-2 days, and pay attention to increasing the temperature and humidity of the chicken house to improve the disinfection effect. ③ One day before introducing the chickens, spray disinfect once with Youlüjing or iodine preparation disinfectant, and disinfect the floor with a 1%-2% caustic soda solution. ④ After introducing the chickens, carry out disinfecting with chickens present 1-2 times per week, alternating disinfectants to avoid the emergence of drug resistance. In seasons with frequent disease, disinfect 2-3 times per week. In hot summer, disinfect once a day, which can also play a certain role in preventing heatstroke and cooling.

Biotech pigs capable of producing a cerebral thrombosis treatment drug have been successfully bred by South Korean scientists
South Korean scientists have successfully bred "biopigs" that produce a cerebral thrombosis (cerebral hemorrhage) treatment drug through their urine. The South Korean Rural Development Administration recently stated: "By injecting the genetic gene for treating cerebral thrombosis (TPA) into pig fertilized eggs, we successfully bred 4 pigs that can excrete cerebral thrombosis treatment substances through their milk and urine." South Korea has become the world's second country after the United States to breed, through genetic modification, animals capable of producing cerebral thrombosis treatment substances. The United States, in 1997, through genetic modification technology,

Why do mushrooms sporadically appear before the mycelium has fully spread
Normally, after the mycelium has fully spread, fruiting begins after a few days of recovery. But sometimes fruiting bodies appear when the mycelium has only spread through 2/3, or even 1/2, of the mushroom log, which is abnormal. Some people advertise that their spawn produces mushrooms before the mycelium has fully spread as a superior "early-maturing, high-yielding spawn," but that is deceptive nonsense; in reality, when this happens, it is a sign of spawn degeneration. There are also external factors, such as: (1) using too much spawn, so old spawn blocks produce mushrooms. (2) packing the substrate too tightly, and the cultivation bag

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.
