为了解决中、低产稻区水稻生产中存在的主要问题,我们于1982年～1984年深入到青田峡市蒋顶乡银光村和小坝乡中沟村,开展水稻大面积丰产示范工作,采用“一主两翼”的工作方法,即与农户签定技术承包合同,进行水稻大面积丰产示范为主,同时针对当地水稻生产中存在问题开展专题试验和调查研究,另一方面利用现场培训农民技术骨干,把科学种田的知识普及推广到千家万户,在栽培措施上,采用“一保三改”的栽培技术,即在采用良种前提下,实行“一次保全苗”和改秧田的高播量为合理播量,改本田的高密度为合理密植,改大头肥为匀施肥。由于措施具体,针对性强,贯彻有力,增产效果显著。三年来在中、低产稻区示范总面积为529.9亩,平均亩产1259.9斤,比对照及原单产水平877.3斤净增稻谷
In order to solve the major problems in rice production in medium and low yielding rice areas, we went to Yinuang Village, Jiangding Township, Qingtianxia City and Zhonggou Village, Xiaoba Township, from 1982 to 1984 to carry out large-scale and high-yield rice demonstration work. “One main two wings” method of work, that is, signed a contract of technology contract with farmers for large-scale demonstration of large-scale rice yield-based, at the same time for the local problems in the production of rice to carry out thematic experiments and research, on the other hand the use of on-site training farmer technology The backbone of the scientific knowledge of farming to promote universal access to millions of households in the cultivation measures, the use of “one security three changes” in cultivation techniques, that is, under the premise of the use of improved varieties, the implementation of “a security seedlings” For a reasonable sowing, change the high-density Honda reasonable close planting, fertilizer to change large fat fertilizer. As a result of specific measures, targeted, strong implementation, a significant increase in production. Over the past three years, the total demonstration area of middle and low-yielding rice areas was 529.9 mu with an average yield of 1259.9 kg per mu, a net increase of 877.3 kg over the control and the previous yield
