The origin of the name of Xiangshui, originated from the water flowing through the production area of ​​the Mudanjiang River flowing out of Jingbo Lake, the sound of running water that can be heard from a few miles inside and outside, called "sounding water", hence the name of Xiangshui Rice. Xiangshui Rice is a green and natural rice that is well-known at home and abroad. Its rice grains are as green as jade and crystal clear. When cooking, the flavor is attacking. The rice tastes soft and soft, and the rice is crystal-clear and translucent. The rice taste is fragrant and palatable. The cold rice does not regenerate. It is appetizing and refreshing. It can be said: "Miqing is as white as jade, and the amount of quality is like sand. The cooking juice is like milk, and the rice oil is bright and fragrant. 』

Geographical environment, Tian Cang, wild wheat, wheat ears, golden rice, Xiangning City, located in the southeastern part of Heilongjiang Province, belongs to the upper reaches of the Mudanjiang River between Zhangguangcailing and Laoyeling, which is the branch of Changbai Mountain. It is surrounded by mountains on three sides and belongs to the low hilly area with an area of ​​1.8 million cultivated land. The area of ​​acre, green food production base is 580,000 mu, and the area of ​​green rice production is 265,000 mu. Ning'an has a long history and superior natural environment. It is the world's second largest mountain lake, Jingbo Lake, National Forest Park, Crater Forest Park, and national key cultural relics protection unit. The Jinglongquan House site in the country is located in Ning'an. Ning'an City is a temperate continental monsoon climate. The annual average temperature is 3.5 °C, the spring is short, the winter and summer are distinct, and the temperature and precipitation are relatively large. The precipitation is 400-600 mm, and the potential of light energy is large, which is equivalent to the amount of solar radiation in the lower reaches of the Yangtze River. The annual average sunshine hours are 2600 to 2700 hours, and the active accumulated temperature of 10 °C or more is 2300 to 2700 °C. In the season of crop growth, the daily exposure is 8 to 10 hours, and the summer solstice can reach 13 to 14 hours. The soil in the territory is dominated by dark brown soil, followed by 9 soils such as white soil, meadow soil, river silt, marsh soil, peat soil and stony soil. The soil fertility is high (organic content 1.5% to 20%, PH is 5 to 7.5), and the water retention and fertilizer retention performance is good. The reason why Xiangshui Rice is of good quality and reputation is far-reaching, thanks to its excellent ecological environment. The land that grows is a large-area basalt “slate land” formed by the volcanic eruption of ancient volcanoes. The humus soil accumulates on it and has a thickness of 20-30 cm. The water quality is the upper reaches of the Mudanjiang River flowing out of Jingbo Lake. Underground spring water, the water quality is clean and excellent, without any pollution. Because the large area of ​​slate reflects heat, the ground temperature and water temperature are about 2~3 °C higher than the average rice field, and the rice maturity is high, which creates the unique rice quality of the ring water rice. Edible value. Cultural background history and legends The discovery of Xiangshui rice is produced in Bohai Town, Ning'an City, Heilongjiang Province. As far back as the Tang Dynasty, the Bohai Sea area has experienced advanced irrigation and rice cultivation techniques. According to the "New Tang Book and the Biography of the Sea", there was a ring of rice in the tribute of the Tang Dynasty. This shows that the reputation of the rice in the history of the water. Since the Tang Dynasty, to the Song, Yuan, Ming and Qing Dynasties, Xiangshui rice has always been the tribute to the royal family. After the founding of New China, Xiangshui Rice became the national banquet for the Great Hall of the People. About Xiangshui Rice, there is a legend in the local folks of Ning'an. A long time ago, there was an old violinist who played a good old guqin near the Longquan House in Beijing. He had a daughter like a flower, called a water child, and the two of them lived together. Wang Haishui County, Wang Haishui County, was outstanding in appearance and took her into the palace. The old violinist missed the water very much. He sat on the basalt on the shore of the Mudanjiang River every day and played his own thoughts. Later, the old violinist died, but the sound of the piano still echoed in the fields, and people called this place "thinking water." Because the rice produced in this area is delicious, people call the rice here, "Thinking Water" rice, which is today's rice. Brand Construction Heilongjiang Xiangshui Rice Industry Co., Ltd. was established in 1998. In 2004, it was restructured into a company limited by shares with a registered capital of 85.5 million yuan. It is a new type of agricultural enterprise integrating Ru0026D, planting, processing and sales of Xiangshui Rice. “National Key Leading Enterprises in Agricultural Industrialization”; the main product – “Shuishui” brand rice is a famous brand product in Heilongjiang Province; the “Yangshui” trademark is a well-known trademark in China. Xiangshui Rice Industry Park covers an area of ​​124,000 square meters. It has two world-class rice processing production lines. The production, storage, drying, testing and other facilities in the industrial park are advanced and complete. The company has two processing bases and three production lines. The annual processing capacity of rice is 150,000 tons and the storage capacity is 100,000 tons. Among them, Xiangshui Industrial Park rice processing production line uses world-class equipment such as Japanese Satake and Swiss Buhler, and is the largest rice processing plant in the southeast of Heilongjiang Province. The company has controlled 47,000 mu of slate fields in the core area of ​​volcanic lava terraces through the land transfer and Xiangshui Rice Professional Cooperative in Xiangshui Rice Protection Area of ​​Ning'an City, and established 33 Xiangshui Rice Cooperative Branches, and more than 3,000 farmers cooperated with the company. Household. The company has now established a production mode of intensive planting management, with an investment of 13 million yuan to establish the Xiangshui Rice Intelligent Temperature Control Nursery Park. Through the unification of rice varieties, unified planting regulations, unified production data, unified field management, and unified harvesting and processing, the production situation of breeding engineering, planting mechanization, variety research, field workshop, farmer workerization, and processing modernization has basically been formed. The establishment of a new type of "company + base + farmers" grain source construction pattern, not only effectively guarantee the company's grain source, promoted the company's industrialized operation, but also better mobilized farmers to increase production and income.

Technical requirements for quality of Xiangshui rice (1) Variety. According to the local accumulated temperature conditions, select high-quality, high-yield, disease-resistant, cold-resistant, and strong tillering varieties. The first accumulated temperature zone is mainly Fujiguang and Wuyou series, and the second and third accumulated temperature zones are above 397 and Kongyu 131. The main, or the varieties that meet the quality characteristics after the quality and variety, and the old varieties are oriented and improved. (2) Seed quality. Seeds are replaced every three years and their quality should meet the requirements of GB 4401.1 “Food crops and cereals”. (3) Site conditions. Climatic conditions: 125 days to 135 days without frost, effective accumulated temperature of 2300 ° C to 2700 ° C for annual activities, annual rainfall of 550 mm to 600 mm. Water source conditions: The irrigation water uses Jingbo Lake water in the upper reaches of Mudanjiang River and other clean and pollution-free water. Soil conditions: The soil type is mostly meadow silt, the soil layer is 20cm to 40cm thick, the organic matter content is 1.5% to 3%, and the pH value is between 6 and 7. Environmental conditions: monitored by the environmental monitoring department designated by the provincial green food management department, the environmental quality of the production area meets the requirements of the “Green Food Local Environmental Technical Conditions”. (4) Cultivation management. 1. Seed treatment After screening grass seeds and impurities, choose to sun-dried for 2d to 3d, then select the yellow muddy water or salt water with a specific gravity of 1.13, remove the glutinous rice, and rinse it twice with water. Then use 10% soaking spirit or 25% Shi Baoke 10ml water 50kg soaking seeds 40kg, soaking seeds at room temperature 15 ° C to 16 ° C for 6d to 7d, directly germination after soaking, bud length 1mm to 2mm when cooling to 15 ° C to 20 °C buds to be broadcast. 2. Breeding method: The seedlings are cultivated by means of large-scale sheds and dry seedlings. The standard of strong seedlings is 35d to 40d, the leaf age is 4 to 5, and the seedling height is 14cm to 18cm. 3. Time and density of transplanting: The daily average temperature is stable when it is inserted through 13 °C, and it is usually inserted from May 15th to 25th. Take a 30cm × 20cm single row or (40cm, 20cm) × 20cm wide and narrow rows and other specifications. 4. Water and fertilizer management: irrigation requires clean water, shallow water irrigation, and promotion of fertility. After the water is transplanted, the seedlings will be filled with 2/3 of the seedlings and returned to the green water. After returning to the green, they should be irrigated with shallow water to promote tillering. In the sub-segment period, when the temperature is below 17 °C, the water is poured from 15cm to 20cm, and the original water level is restored immediately after the cold damage. The milk is matured intermittently and the water is cut off at the end of the yellow ripening period. Fertilization requires the use of chemical fertilizers and organic fertilizers.
