前言我省的固有耕作制度是“以壠作为基础,扣交替的輪耕制度”。近十几年来随着新式畜力农具、机引农具的推广使用,继而出現了壠平結合的平翻平播后起壠的耕作方法。固有壠耕作制是农民在长期生产实践中創造出来的,适于当地环境条件的畜力和手工操作的耕作制度。經驗証明,两者对我省实現农业机械化尙不能完全适应。固有壠耕作制度,虽对当地自然条件有較大的适应性,但因原有的工具不能适应发展农业生产的要求,对实現机械化和提高播种质量都有一定影响。平翻平播后起壠耕作制,虽基本上可以适应机械耕作,(但只能在一定区域內推广或仅适于某 Preface The province’s inherent farming system is “to 垅 as the basis, buckle alternate rotation system ”. In the past ten years, with the popularization and application of new-typed livestock tools and machine tools, there has emerged a tillage method of combining flat-topping and flat-screen sowing. The inherent farming system is a farming system created by peasants in long-term production practices and adapted to the local environmental conditions and animal husbandry. Experience shows that the two can not fully adapt to the realization of agricultural mechanization in our province. Although the inherent farming system has great adaptability to the local natural conditions, the existing tools can not meet the requirements of developing agricultural production and have an impact on the mechanization and the improvement of sowing quality. Flat-screen flat-screen plowing farming system, although basically can adapt to mechanical farming (but only in a certain area to promote or only suitable for a
