我县近六年来重视农业气候资源的开发利用,使农业布局、耕作制度、技术措施的采用趋向合理,变农业气候资源优势为经济优势,取得了一定的实际效益。一、海拔200米以上的丘陵≥10℃的活动积温4800—4300℃,不宜双季稻栽培,调整为稻麦两熟,使水稻生育期热量充足,夏无高温危害,春秋不受低温影响,又能充分利用光温效应,有利粮食高产。1982—1984年在不适宜粮食三熟制的地区扩种稻麦两熟7.5万亩,累计增产粮
In the recent six years, our county has attached great importance to the development and utilization of agricultural climate resources, which has made the adoption of agricultural layout, farming system and technical measures reasonable and has made economic benefits by changing the advantages of agricultural climate resources and has achieved certain practical benefits. First, the hilly above 200 meters above sea level ≥10 ℃ activity accumulated temperature 4800-4300 ℃, should not double cropping rice, adjusted to rice and wheat two crops, so that the rice during the growth period adequate heat, summer no high temperature damage, spring and autumn are not affected by the low temperature, But also make full use of light temperature effect, favorable grain yield. In 1982-1984, 75,000 mu of rice and wheat double crop were expanded in areas not suitable for grain,
