在丘陵起伏、沟壑纵横的陕北高原,修建梯田是防止土壤侵蚀,改广种薄收为少种高产,实行农林牧并举的主要途径。但由于我们对当地的土壤、气候等自然规律没有完全掌握,对截短坡长、减缓坡度的效益认识不够深刻,三十年来,兴建的梯田虽然也起了增产拦泥的作用,但有些标准不高,耕作不便,增产不够显著,需要研究改进。现就梯田如何建设的问题谈些个人的看法。
In the hilly and hilly areas of North Shaanxi Plateau, the construction of terraced fields is to prevent soil erosion, change the thin harvest for a few kinds of high yield, the main way of implementation of agriculture, forestry and animal husbandry simultaneously. However, since we do not fully grasp the natural laws of the soil and climate, we do not have a deep understanding of the benefits of truncated slope length and slope reduction. Although the terraced rice fields have played a role in increasing sludge production in the past 30 years, some standards Not high, farming inconvenience, not enough significant increase in production, need to study and improve. Now on the issue of how to build terraces talk about personal views.
