New bamboo-rice varieties successfully bred at the Meizhou research base
Recently, the author learned from the bamboo-rice research base of the Meizhou Agricultural School in Meizhou City, Guangdong Province that various experiments on drought resistance, disease resistance and ratooning ability of bamboo rice will be carried out here this year, and scientific research on new varieties such as the special bamboo rice "bamboo purple rice" will also be launched. At the same time, bamboo rice 966 and bamboo rice 989 will continue regional trials across the province. Meizhou City has also set up 6 sites in Jiaoling, Meixian, Xingning and Wuhua counties and cities, totaling 300 mu, for trial demonstration planting of bamboo-rice cultivation techniques. The agricultural school has opened a test base to conduct drought-resistance tests on bamboo rice 966 and disease-resistance tests on bamboo rice 989.

Qinghai Successfully Introduces a New Fish Species from Russia
The new fish species introduced from Russia for trial breeding - the whitefish (Coregonus peled) - will be promoted on a large scale in Qinghai Province. The introduction of this "foreign fish" has not only broken the previously rather monotonous aquaculture pattern in the province, but also moved Qinghai's fisheries one step closer to the international market. In order to make the whitefish breeding and cultivation technology more mature in the province's aquaculture sector, Qinghai Province recently invited Alexander Ivanovich Litvinenko, president of the Research Academy of the Siberian Fisheries of the Russian Federation and academician of the Russian Academy of Sciences, to visit Qinghai for inspection and technical analysis, and to provide market information.

New cotton variety Suza 3 successfully developed in Jiangsu
The new cotton variety "Suza 3", jointly bred by the Institute of Industrial Crops of the Jiangsu Academy of Agricultural Sciences and other institutions, has been successfully developed and recently passed national new variety approval in Jiangsu Province. It is reported that this is Jiangsu Province's first two-gene transgenic insect-resistant hybrid cotton. Tests show that it has strong resistance to common pests such as the cotton bollworm and the pink bollworm. According to experts, at present the insect-resistant cotton in the cotton region of China's Yangtze River basin generally has only a single insect-resistant gene - the "BT insect-resistant gene", while Suza 3, in addition to containing the above gene, also has the "C

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. Last winter's cuttings

Ninghua, Fujian successfully introduces "Taiwan Fat Ginger" and enjoys a bumper harvest
Li Xinfu, a ginger farmer in Xiasha Village, Zhongsha Township, Ninghua, Fujian, began introducing 15 mu of "Taiwan Fat Ginger" in 2004. Through two years of trial planting, he accumulated relatively rich successful experience in high quality and high yield. This year, he rented 100 mu of rice fields in Gaoshengbei to plant "Taiwan Fat Ginger", and fresh ginger has now begun to be sold on the market. The average yield per mu can reach 2000 kg. All products are exclusively sold by Longyan Taifu Agricultural Development Co., Ltd. at 2.4 yuan per kg. A net profit of more than 3000 yuan per mu can be obtained, with remarkable benefits. According to the characteristics of "Taiwan Fat Ginger" being tolerant of fertilizer, fond of shade,

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,
