Soybean molecular breeding technology successfully developed by South Korea
The Agricultural Biotechnology Research Institute of South Korea's Rural Development Administration recently successfully developed a soybean molecular breeding technology, which means that South Korea's mass production of organic soybeans containing anti-cancer components will become a reality. South Korea's regeneration technology for soybean plant bodies through tissue culture is not well developed, so trait-transformed soybeans are mainly imported from the United States. The Rural Development Administration revealed that molecular breeding technology is called third-generation genetic engineering technology. Using this technology, soybeans with higher added value can be produced, which is of great significance for increasing farmers' income.

New colorful soybean varieties successfully cultivated in Henan
A type of soybean displaying a riot of colors has recently been successfully cultivated by the Agricultural Science Institute of the Huangfanqu Farm in Henan Province and has begun to be vigorously promoted. Besides the commonly seen yellow, this soybean also comes in black, red, green and other colors, and each color is further divided into several sub-varieties according to the depth of its shade. Colorful soybeans are a high-efficiency cash crop; besides being eaten, they also have high ornamental and medicinal value. Compared with the ordinary soybeans cultivated in the past, the newly cultivated colorful soybeans show no difference in planting techniques or yield. According to expert predictions, the market

Key Points of Agaricus bisporus Cultivation Technology to Help You Grow Successfully
Agaricus bisporus, also called white mushroom or button mushroom, is commonly known simply as mushroom. It is the most widely cultivated and highest-yielding edible fungus in the world. It has high nutritional value and good market demand (especially after China's accession to the WTO, export volumes doubled). Its main production raw materials are rice straw, corn stalks (cobs) and livestock manure, with high yields and extremely significant economic benefits. Therefore, in recent years it has developed quite rapidly in China, spreading from the traditional main growing areas of Fujian and Zhejiang in the south to Hebei, Shandong, Anhui, as well as Hunan, Hubei, Jiangsu and other places. The rise of this industry has indeed enabled many

Black potatoes successfully cultivated in Heilongjiang Province
The potatoes people see in daily life are all yellow or white, but now a kind of black potato has been successfully cultivated in Mudanjiang City, Heilongjiang Province. This potato is black-purple in appearance, with an oblong tuber shape and deep purple flesh. Its starch content is higher than that of ordinary potatoes, and its texture is more "mealy" than ordinary potatoes. Li Hongxing, a senior agronomist at the Mudanjiang City Vegetable Science Research Institute, said that this potato took 4 years to cultivate successfully, and through successive years of generation-advancing cultivation, 0.4 hectares have been cultivated so far. Last autumn, the harvest reached 8,500 kilograms, and starting this year it can be

Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control
