| 摘要: |
| 1991～1993年在乾县中南部灌区，通过采用高产优质品种、实行“三密一稀”种植、科学配方施肥、建立合理群体结构及科学管理等综合配套技术，3年累计开发吨粮田2.07万hm2，达标1.39万/hm2，产量达15ｔ/hm2以上。试验证明，吨粮田的建设与开发是大幅度提高粮食产量、促进农村经济发展的战略措施，对解决人多地少、人增地减、粮食匮乏的社会问题有深远意义。 |

| Abstract: |
| During the period of 1991～1993 in the irrigated area in the mid-south of Qianxian County,the comprehensive perfection techniques of the rational population structure and scientific management were established through the adoption of high-yield,fine-quality crop varieties,the praetice of“3-close and l-sparse plantings”,and the application of scientifically prescribed fertilizers.With in 3 years 20.7 thousand hm2of one-ton-permu grain field were developed,13.9 thousand hm2 of them reached the target requirements with the yield of over 15t/hm2.The experiment has proved that the construction and development of one-ton-permu grain field are a strategical measure to increase grain yield to a great extent and to promote economic development in the countryside; they also have a profound and lasting significance for solving the social problems of large population with shortland,growing population with decreasing arable land,and food shortage. |
