Fully Enclosed Cutting Propagation Technique for Azaleas
1. Selecting and building the cutting bed: Choose a sheltered, shady, well-drained site to build the cutting bed. Cover it with a black shade net (60% to 70% shading rate); the sides of the shade net must hang down to the ground so that the entire structure is in a cool, shady environment. On the seedbed, set up a small arch tunnel with a center height of 40 cm. Cover it with a layer of plastic film, then a layer of black shade net (60% to 70% shading rate). 2. Laying the substrate: In early May, mix leaf mold and perlite (1:1) evenly and spread it in the seedbed to a depth of no less than 30 cm. Level it

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 Skillfully Master the Pig Feed-to-Water Ratio? A Must-Read for Pig Farmers
Mixing pig feed with too much water and making it too thin is a long-standing habit among rural people. It has many drawbacks: First, when the feed is mixed too thin, the water content in the daily ration increases relatively, the nutritional components are insufficient, saliva secretion is greatly reduced, the gastric juice is diluted, and the feed stays in the stomach for a shorter time, severely reducing the feed's utilization rate. Second, it increases the physiological burden and raises the body's heat consumption. In addition, in autumn and winter, because pigs urinate more, the pigpen becomes damp and cold, seriously affecting the pigs' growth, development and health. It can thus be seen that pig feed is better prepared as a moist mash, which not only saves

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

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 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.
