摘要
为探究中国保护性耕作研究的产量效应及区域分布情况,收集自2006年至2019年3月公开发表的涉及保护性耕作的研究论文,对田间试验条件下具有明显产量效应的期刊论文进行整理分析。研究发现,在全部产量研究的结果中,增产、平产、减产的研究结果所占比例分别约为60.96%、24.32%和14.72%。保护性耕作产量效应的区域特色表现在东北地区实施保护性耕作产量研究结果多为增产,增产结果约占77%;而平产和减产的研究结果在黄淮海、华北平原较多,分别约为32%和22%。在保护性耕作产量研究的试验中,秸秆处理措施研究占全部研究的60%以上,少免耕研究相对较少,且免耕是减产研究结果中占比最多的保护性耕作措施。小麦、玉米、水稻仍然是保护性耕作主要的研究对象,78%以上的研究集中在这三种作物上。随着生态环境日益受到重视,越来越多的作物将成为保护性耕作的研究对象。
To understand the effects of conservation tillage on crop production and regional distribution of conservation tillage research in China,we analyzed the relevant research from 2006 to March 2019 and summarized our findings herein.Our investigation indicated that,among all research papers regarding conservation tillage,the percentages of reported yield increase,no effect,and yield reduction were 60.96%、24.32%and 14.72%,respectively.The effect of conservation tillage on crop production was distinct in different regions:yields were mostly increased in Northeast China(77%);while yields were either not affected or reduced at a considerable proportion in the Huanghuaihai(32%)and North China Plains(22%).Among different practices of conservation tillage,straw treatment studies accounted for more than 60%,and reduced or no-tillage were less studied.Wheat,maize and rice remain the main research subjects for conservation tillage,with more than 78%of studies focusing on these three crops.In addition,no-tillage caused the most yield reduction in all protective tillage measures.
