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.

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.
