| 中文摘要: |
| 燕沟流域通过坡耕地改梯田、推广抗旱高产品种和地膜覆盖技术、增加化肥投入、大垄沟规范化种植、调整粮食作物种植比例,改造了生产要素组合条件,使粮食单产稳步提高,粮田生产力发生了较大的跃迁。到2000年,燕沟流域粮食作物播种面积较1997年减少了59.1%,粮食平均单产较1997年翻了两番,粮食总产量较1997年提高了33.7%,实现了减地不减产和增产增效的效果。 |
| 英文摘要: |
| The experiment and demonstration in Yangou catchments adopted such measures as conversing slope faming land into terrace land, extending drought-resistant crops varieties, increasing fertilizers inputs, adjusting the land area for grain production and improving the combinative factors of production elements to make the grain yield rapidly and steadily increase, and greatly enhance the productivity of grain-producing land. In the catchments, by 2000, the land area for grain production had reduced by 59.1% compared with that in 1997; but the average grain yield had quadrupled that in 1997 the total grain yield had increased by 33.7% compared with that in 1997, and then he effect that decreased grain land did not result in decreased grain production was realized. |
