解决水土流失和土壤贫瘠的问题,必须研究水和土壤运动规律 水土流失问题,已经成为当今最大的农业环境问题,干旱缺水和土壤贫瘠化已是我国北方农业生产的两个瓶颈,北方旱作农业要有较大发展,必须解决干旱缺水和土壤贫瘠化问题。而解决这两个问题的关键在于研究水和土壤这两个农业环境要素的运动规律,如果我们能从水循环中开发淡水资源,依靠土循环恢复土壤肥力,三北旱作农业就可能摆脱缺水和土壤贫瘠的困境,得以较大发展。
To solve the problems of soil erosion and soil infertility, we must study the laws of water and soil erosion, which has become the biggest agricultural environment problem today. Drought and water shortage have become the two bottlenecks of agricultural production in northern China. To have greater development of agriculture, we must solve the problems of drought and water shortage and soil impoverishment. The key to solving these two problems lies in studying the law of movement of water and soil, the two agro-environmental factors. If we can develop fresh water resources from the water cycle and rely on the soil cycle to restore soil fertility, agriculture in the Three North Dynasties may get rid of water shortage And soil poor plight, to greater development.
