Helen rice is full of particles, crystal clear, soft and smooth, and the rice is fragrant. It is rich in a variety of nutrients. The porridge syrup, such as milk steamed rice oil, is bright and fragrant (high in vitamin E). It is fragrant and palatable. The unique leftovers are not rejuvenated, and the nutritional value is extremely rich. Helen rice is affected by the unique geographical and climatic factors of the producing area, with more dry matter accumulation, moderate amylose content and higher amylopectin content. Due to the large temperature difference between day and night in the mature period of rice production, the accumulation of instant double-chain sugar in organic rice is more suitable for human health.

Helen City is located in the central part of Heilongjiang Province. It is a cold temperate continental climate with distinct seasons and concentrated precipitation. Helen is rich in natural resources and is one of the three black land in the world. It is known as the “granary”. Five rivers, such as the Tongken River, the Keyin River and the Helen River, traverse the east and west, and five large and medium-sized reservoirs such as Lianfeng and Dongfanghong and more than 30 small reservoirs are scattered. Helen is rich in rice, soybeans, corn and other food crops. Selenium (Se) was identified as an essential trace element in the 1950s. Selenium has good anti-oxidation, detoxification and anti-cancer effects. In 1973, the United Nations Health Organization announced that selenium is an essential trace element in human body. The Chinese Nutrition Society has listed selenium as one of the daily dietary nutrients. Eating natural selenium-rich rice is good for health. In 2010, Heilongjiang Provincial Department of Land and Resources census Helen soil, Helen is located in the main deposit zone of soil selenium deposit, Helen soil is naturally rich in selenium. The National Food Quality Supervision and Inspection Center detected a selenium content of 0.0329 mg per kilogram in selenium-enriched rice in Hailun City, Heilongjiang Province. Helen's selenium-enriched long-grain rice is affected by the unique geographical and climatic factors of the cold soil of the cold region in the producing area. The accumulation of dry matter is large. The temperature difference between day and night in rice maturity is large, and the high-dose double-sucrose content in rice can be said to be superior. Helen, a selenium-rich treasure, is naturally rich in selenium when it comes out, and it is between the content of the human body. This is unmatched by other products that add selenium to agricultural products. Helen is an important commodity grain base county in the country and an important raw material base for green organic food production in the country. It has been rated as an advanced county for grain production by the state for 12 consecutive years. Through the national project test, the Heilongjiang Provincial Bureau of Geology and Mineral Resources published authoritative data. Helen City is a selenium-rich core area in the Songnen Plain. After a rough calculation, Helen's selenium (0.325mg/kg-0.4mg/kg or more) cultivated land area is 2.24 million. Mu, accounting for 48.2% of the city's cultivated land area, foot selenium (0.175mg/kg-0.325mg/kg) arable land area of ​​2.41 million mu, accounting for 51.8% of the city's cultivated land area, which means that Heilongjiang's entire area of ​​4.65 million mu of cultivated land planted All agricultural and special products are all selenium-rich, and the natural selenium-enriched by-products reach 50%. At the same time, through the provincial geological and mineral resources bureau to the soil and environmental testing of the city, Helen soil is a pure land without heavy metal pollution, all of which meet the national environmental quality first-class standard, and naturally meet the requirements of AA-level green food base.

Helen rice quality technical requirements I. Variety Selection of varieties with suitable taste characteristics such as 绥粳4, 垦米12, 绥粳18, etc. 2. Site conditions The soil types of cultivated land are black soil, meadow soil and paddy soil. The thickness of the tillage layer is ≥ 25 cm, the soil organic matter content is ≥ 3%, and the pH is 6 to 7. Third, cultivation management Germination: From late March to early April, the intelligent germination chamber is soaked and germinated, the buds are good, uniform, and the germination rate is over 90%. 2. Adopt plastic shed squat-type dry seedling technology, sowing period from April 5th to April 15th, machine inserting seedlings 100g per bud seed, machine seedlings seedlings bud seed 125g per square, square bud seed 600 Up to 750 grams. The seeding is required to be uniform and the amount of the seeding is accurate. 3. Interplanting: During the transplanting period, the seedling mechanical transplanting in the conventional dry breeding period is from May 10 to May 25, and the age is 30 to 35 days; the large seedlings are planted from May 15 to 25, and the age is 35 to 40 days; Hectares ≤ 250,000 holes, 3 to 5 per hole. 4. Field fertilizer management: 30 tons of fertilizer per hectare, three rounds of application, strengthen soil fertility. Adopting the soil testing and formula fertilization technology, the potassium fertilizer in the high-yield research and development block should be appropriately increased, and the silicon fertilizer should be added. Applicable total fertilizer: pure nitrogen (N) ≤ 100kg, pure phosphorus (P2O5) ≤ 50 kg, pure potassium (K2O) ≤ 50kg. 5. Harvest: Harvest period is from September 15th to October 10th. 6. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. 7. Processing: rice → screening → cleaning → stone removal → magnetic separation → glutinous rice → grain separation → rice milling → broken rice → color selection → polishing → inspection → packaging. Fourth, quality characteristics Sensory features: Helen rice is full of rice, crystal clear and translucent, low white grain rate, small white belly, hard and tough texture, soft and delicious rice, not reborn. 2. Safety and other quality technical requirements: Product safety indicators and other quality technical requirements must comply with relevant national regulations.
