Funing County, Hebei Province, one of the key producing areas of rice, planting area of about 15 acres. From 1980 onwards, how to make use of the experimental crop has been explored. Several cultivation modes with high yield and high efficiency have been explored. In 1994, the area has grown by 17,000 mu with an annual economic benefit of 9.6 million yuan. Funing County 174 days frost-free period, the temperature ≥ 0 ℃ 80% of the accumulated temperature guarantee rate of 3941 ~ 4117 ℃, ≥ 10 ℃ 80% accumulated temperature guarantee rate of 3653.3-3873.3 ℃.
