我县位于甘肃省中部干旱地区,1989年在川水地种各种形式的带状丰产示范田11400亩,平均亩产557.9公斤,是这些地方粮食平均亩产的5.8倍。文峰镇65亩平均亩产960公斤,南安乡五一四社120亩平均亩产970公斤,小面积达到和超过“吨田”的也不乏其例。其措施是: 1.合理的带田形式万亩带状示范田分别种植在10个乡(镇)243个合作社之中,海拔高度从1620米到2167米都有分布。由于涉及面广,各地的气候条件及栽培条件差异较大。为此,
My county is located in the arid area in the middle of Gansu Province. In 1989, 11400 mu of various forms of belt-shaped high-yield demonstration fields were cultivated in Kanshui. The average mu yield was 557.9 kilograms, 5.8 times of the average per mu of grain in these areas. The average yield of 65 mu of Wenfeng Town is 960 kilograms. The average yield of 120 mu of Nanlou Town 514 Community is 970 kilograms. The small area has reached and exceeded that of “tons of land”. The measures are as follows: 1. A reasonable strip-shaped demonstration area of 10,000 mu is planted in 243 co-operatives in 10 townships (townships). The altitude is from 1620 to 2167 meters. Due to the wide range of coverage, climatic conditions and cultivation conditions vary widely. to this end,
