我县位于黔中向黔西北高原过渡的斜坡地段。为低中山、中山地貌,属黔中稻作区。90％的稻田分布在海拔1000～1400米的丘陵地区,少数面积分布在海拔1000米以下的河谷和海拔1400米以上的高山。为了探索我省水稻生产的高产规律,省农业厅粮油处与农技总站统一部署本试验,并安排我县为一个试点,承担高产、品比、密度、不同用量的追肥四个项目。经1980～1982连续三年的观察,现已结束,总结如下。
My county is located in Qianzhong to the northwest plateau slope transition. For the low Zhongshan, Zhongshan landscape, is a middle-Guizhou rice area. Ninety percent of the paddy fields are located in the hilly areas of 1,000 to 1,400 meters above sea level, with a few areas located in valleys below 1,000 meters above sea level and at altitudes above 1,400 meters above sea level. In order to explore the law of high yield rice production in our province, the Bureau of Grain and Oil of Agricultural Department of Hunan Provincial Department of Agriculture and the Agricultural Technology Depot unified deployment of this experiment and arranged for the county as a pilot to undertake four projects of top dressing with high yield, product ratio, density and different dosage. After 1980 ~ 1982 for three consecutive years of observation, is now over, summarized as follows.
