Koizumi village is located in the mid-levels area, where many springs once flowed out from the crevices at the foot of the mountain, and the geographical environment and climatic conditions are unique. Since the Wanli period of the Ming Dynasty, rice cultivation has never stopped. According to legend, the spring water here was dug by Qi Huangong during the Spring and Autumn Period when he led a great army to crusade against Ganoderma lucidum and solitary bamboo, and the water quality was sweet. According to local legend, Koizumi's water quality is very good. At that time, the Qing court sent people to check the springs here. After weighing, it is considered that the water in Yuquan Mountain in Beijing is basically the same, but it is not adopted because it is far from Beijing. After the reform and opening up, it passed the appraisal of the national technical appraisal group for drinking natural mineral water. This is Koizumi in the northeast, passing through Yutian, Sanlitun and Linnancang, and reaching the natural mineral spring line of Dongjizhuang in the southwest. In Koizumi's area, it is understandable that the rice produced by long-term irrigation with mineral water is of good quality. In the 1970s and 1980s, due to various reasons, Koizumi's water output gradually decreased, and in the 1990s, it stopped dripping. During this period, rice fields, like spring water, grew from more to less and from less to nothing. Nowadays, the rice fields near Koizumi Village have already become dry fields, and even the shadow of rice can't be found, let alone "rouge rice". On 20 10, the local area tried planting again, sowing in a 60-mu planting base, ploughing the land, preparing organic fertilizers such as biogas residue, and drilling two mechanical wells. After the bumper harvest of rouge rice, a catty of rouge rice sold for 4000 yuan a catty, which brought huge benefits to farmers. In October, 20 12 165438 10, the column group of CCTV's Daily Agricultural Economics reported this with "Different Rouge Rice".
