Comprehensive High-Yield Cultivation Techniques for Soybean in High-Cold Regions
Soybean is the main crop in the Jiamusi region of Heilongjiang Province, with an annual sown area of more than 900,000 mu, accounting for more than 75% of the total sown area. For a long time, due to the cold climate, short frost-free period, insufficient accumulated temperature, and lack of suitable varieties, soybean yields have remained stagnant at only about 150 kg, and in disaster years even less than 100 kg. In view of this, based on the climatic characteristics of Heilongjiang Province, we have developed several techniques suitable for soybean

8 Precautions for Selecting Superior Soybean Seeds
1. Pay attention to the seed purity and germination rate. 2. Pay attention to whether free consultation and technical guidance are promised. 3. Pay attention to whether sales outlets have been set up indiscriminately. 4. When mail-ordering seeds, pay attention to sending money via the local post office (branch); do not enclose cash in the letter. Clearly write your detailed address and name, and note the variety and quantity purchased in the remarks column. 5. Pay attention to clearly identifying the trademark and packaging marks. 6. Pay attention to agreeing on the seed price. 7. Pay attention to whether seed quality is guaranteed. 8. Pay attention to contacting by phone or letter before introducing a variety, and you may also consult the relevant units.

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.

Analysis of the Key Points of Integrated High-Yield Technology for Rainfed Soybean
I. Basic Information: 1. Project source: One of the projects under the "Comprehensive Technical Research on Increasing Production in the Sanjiang Plain Agricultural Region" issued by the National Science and Technology Commission during the "Sixth Five-Year Plan" period. A national key research project. 2. This project was reviewed in December 1985 by an appraisal committee composed of 20 experts and scholars including famous professors Wang Jinling and Zhang Zijin from China's soybean science community. The appraisal concluded that the research direction was correct, the approach was right, the measures were appropriate, and the results were remarkable, with an obvious yield-increasing effect on subsequent crops as well. Breakthrough progress had been made in integrated research and supporting technologies,

Analysis of the Northeast Soybean Market and an Explanation of the Principles of Genetically Modified Technology
1. So-called genetically modified crops are created by using biotechnology to transfer genes from certain organisms into other species, altering the organism's genetic material so that its traits, nutritional quality, consumption quality and other aspects are changed toward goals needed by humans. In our country, genetically modified organisms are still relatively rare. Up to now, only 6 genetically modified crops have been approved for commercialization by the Ministry of Agriculture's Bioengineering Safety Committee, of which 3 involve crops, namely two kinds of tomatoes and one kind of sweet pepper. 2. Recently, news has spread frequently across various parts of the country that soybeans and soybean meal are rising across the board.
