The ferro-ric rice is planted in the cold soil black soil advantageous industrial belt in the third accumulative temperate zone and the fourth accumulative temperature zone in Heilongjiang Province. It belongs to the northern temperate continental climate, with high soil organic matter content, fertile soil, good permeability and 80% of rice producing area. Self-flow irrigation, good water quality and no pollution. Good soil and climatic conditions make the iron rice color white and jade, the crystal is crystal clear, the taste is sweet and soft, the nutrition is unique and rich. When cooking, you can smell the rich rice flavor, and still maintain good taste after cooling. A must-have item on the table.

At present, the rice planting area of ​​Tieli City has grown to 652,000 mu, of which green organic rice planting area is 414,000 mu, accounting for 63.5%, and grain output is 517,000 tons. Tieli City has won many honorary titles such as China Green Ecological Rice Demonstration City, National Grain Production Advanced County, and National Ecological Demonstration Zone. “Tieli Rice” also passed the national geographical indication protection product certification, and was successfully approved as a geographical indication certification mark.
