近年来,淮北地区有机肥施用量逐年减少,作物秸秆大量浪费,实在可惜,为了开发利用秸秆资源,我们从80年代起,就开始对秸秆直接还田技术试验示范、推广,取得了显著效果.为了更好地利用当地丰富的秸秆资源,克服秸秆还田的盲目性,使秸秆还田各项技术环节有章可循,提高秸秆还田效益,推动秸秆还田技术的发展.根据淮北地区一年多熟制种植习惯、气候变化、土壤状况、种植制度和秸秆还田方式等实际情况,在各地区多年深人研究和总结群众经验的基础上,提出秸秆还田的技术要领.
In recent years, the amount of organic fertilizer in Huaibei area has been decreasing year by year, and a great waste of crop stalks is a pity. In order to develop and utilize straw resources, we started to test and popularize straw direct returning to fields technology since the 1980s and achieved remarkable results. In order to make better use of the abundant straw resources in the area and overcome the blindness of returning straw to soil, the technical aspects of returning straw to soil can be followed in order to improve the efficiency of returning straw to soil and promote the technology of returning straw to soil. Years of cooked planting habits, climate change, soil conditions, planting system and straw return to the actual situation in many areas in various years of in-depth study and summary of the masses based on the experience, put forward the technical essentials of straw.
