Qing'an's 700,000 mu of rice adopts cold-region dry seedling cultivation and controlled irrigation technology for water saving and high yield
The controlled irrigation, water-saving and high-yield technology for cold-region dry seedling rice has been successfully tested in Qing'an. This year, 700,000 mu of rice in this county are using this technology. According to expert calculations, it saves about 450 cubic meters of water per mu, saves 11.2 yuan in pumping costs, and increases yield by an average of 22 kg per mu. In recent years, through the trinity approach of "engineering water saving, mechanism water saving, and technical water saving," Qing'an has reduced irrigation water per mu from nearly 1,000 cubic meters to 500 cubic meters. Over 10 years, it has expanded the paddy field area from 640,000 mu to 1.17 million mu, accounting for half of the cultivated land area. Last year

How is Acetes processed? A detailed guide to Acetes processing technology
Acetes, namely Acetes chinensis, also known as small white shrimp, water shrimp, etc., belongs to the class Crustacea, family Sergestidae, with a laterally compressed body and a thin shell. Body length is generally 2.5-4 cm. The rostrum is short and small, roughly triangular in side view, with the lower margin oblique and slightly curved, and the upper margin bearing two teeth; the telson is very short, rounded at the end, without spines, and the posterior half of the lateral margins and the terminal margin bear feather-like setae. The first three pairs of walking legs are tiny chelate, and the posterior two pairs are completely degenerate. The body is colorless and transparent, with only the mouthparts and the second antennae flagellum red, the ventral surface of the sixth abdominal segment slightly red, and the base of the endopod of the uropod bearing 3-8 red spots

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.

Detailed Explanation of Key Points for Soybean Narrow-Row Dense Planting Cultivation Technology
Soybean narrow-row dense planting cultivation is currently an advanced cultivation technology with a relatively large application area and rapid development speed in international soybean cultivation. Heilongjiang Province began this practice in the early 1990s and designated it as a key research project of the Provincial Party Committee in 1995. 1. Select suitable varieties and carry out proper seed treatment. Narrow-row dense planting must select short-stalked or semi-short-stalked varieties with lodging resistance and high yield potential. Currently, the more suitable varieties applied in production include Hefeng 25, Hefeng 35, Suinong 14, Beifeng 14, Beifeng 1

Detailed Explanation of Key Points of Soybean Good Seed Propagation Technology
Soybean is a self-pollinating crop. Due to mechanical mixing, adverse climatic conditions and cultivation conditions, as well as natural hybridization and other reasons, seed quality often deteriorates. Therefore, self-pollinated seeds cannot be used for a long time, and seeds should be replaced every three years. Thus, it is necessary to persist in purification and rejuvenation and to do a good job in good breeding work in order to maintain the seed quality of superior varieties. 1. Methods for purification and rejuvenation of soybean varieties (1) Line selection The commonly used method for soybean purification and rejuvenation consists of three steps: individual plant selection, line identification, and mixed high-multiplication propagation. Separate individual plant selection

Detailed Explanation of Key Points of Controlled Atmosphere Preservation Technology for Mushrooms
1. Harvesting: Harvest when the fruiting bodies have fully grown and their volume has increased noticeably. If harvested too early, the mushrooms will be of poor quality and the yield will be reduced; if harvested too late, the fruiting bodies are more likely to age, open their caps, and change color. During harvesting, mechanical damage should be reduced, and harvesting tools and packaging containers should be cleaned and disinfected. 2. Pre-storage treatment: After the mushrooms are harvested, trim off the mushroom stems. If the mushrooms have yellowed or turned brown, rinse them in a 0.5% citric acid solution for 10 minutes, remove them and drain off the water droplets, then quickly pre-cool the mushrooms. Pre-cooling is very important. Because at higher temperatures, it will accelerate

Detailed explanation of key points of mushroom preservation technology, easily extend storage time
Mushroom preservation methods include modified atmosphere preservation, low-temperature preservation, radiation preservation and brine preservation, etc. The methods are: modified atmosphere preservation uses simple modified atmosphere storage, within 3 to 5 days it can keep mushrooms fresh and tender without opening their caps, basically without browning, and with a water loss rate below 1%. At present, breathable plastic film bags are generally used for packaging, maintaining an oxygen concentration of 1% and a carbon dioxide concentration of 10% to 15% inside the bag, which can keep mushrooms white for 4 days with good freshness. Cold storage preservation: low temperature can keep mushrooms fresh and of high quality. During storage and transportation
