我市属鄂西南丘陵地区,境内海拔150～300米间约有水田3.5万亩,占水田总面积25％。这一带,年≥10℃积温5012～5235℃,现行种植制度是油稻或麦稻两熟。为了挖掘耕地的增产潜力,开拓新的利用途径,三年来,连续开展了再生稻试验示范。1988年从海拔150～200米的五眼泉周湾村起步,试种汕优64再生稻5.9亩,获头季平均亩产591.7公斤,再生稻亩产203.6公斤的较好收成,第二年扩大到近百亩,头季亩产485公斤,再生稻亩产154公斤。1990年向海拔300米左右的毛湖埫乡逐鹿山村推进
My city is southwestern Hubei Province, hilly areas, the territory of about 150 to 300 meters above sea level paddy fields about 3.5 million mu, accounting for 25% of the total paddy field. This area, the annual ≥ 10 ℃ accumulated temperature 5012 ~ 5235 ℃, the current planting system is double ripe rice or wheat. In order to tap the yield potential of cultivated land and explore new ways of utilization, the demonstration experiment of regenerative rice has been carried out continuously for three years. In 1988, the project started from Zhouwan Village of Wuyaoquan at an elevation of 150-200 meters to test 5.9 acres of Shanyou 64 ratoon rice, achieving a good harvest of 591.7 kilograms per mu in the first season and 203.6 kilograms per mu for regenerating rice. The second year Expanded to nearly 100 acres, the first quarter of 485 kg per mu, 154 kg of reclaimed rice per mu. In 1990 to about 300 meters above sea level Maoyu Township Zhuerlu mountain village to promote
