连年翻地作为土壤耕作的基本措施,已有悠久的历史,它在发展农业生产和提高农作物产量过程中,超过很大作用,至今仍在农业生产中广泛应用。但翻地使有机质的分解加速,土壤失墒严重,机械耗能量大,作业成本高。为此,借鉴国内外低耗高效妁少耕法经验,研究麦豆产区少耕法的效益。提出麦、豆不同轮作方式下的适宜的少耕法,并探讨抗旱保墒和培肥地力及其增产的效应,为生产上提供科学依据。本地区土壤特性:质地粘重,透水性差,耕性不良,适耕期短,冻结期长达十个月
As the basic measure of soil cultivation, perennial turning has a long history. It has played a significant role in the development of agricultural production and the improvement of crop yield. It is still widely used in agricultural production. However, turning the ground to accelerate the decomposition of organic matter, soil moisture loss serious, mechanical energy consumption, high operating costs. For this reason, drawing lessons from domestic and foreign low-efficient and low-tillage less experience, to study the benefits of less tillage farming methods. The suitable tillage method under the different rotation modes of wheat and beans was put forward and the effects of drought resistance and soil conservation and soil fertility improvement and their yield increase were discussed to provide a scientific basis for production. The soil characteristics of the region: sticky texture, poor water permeability, poor tillage, short adaptability, freezing period of up to ten months
