摘要
以水田机械化深翻技术为基础,采用对比试验验证深翻作业模式的可行性。试验结果表明:在农艺允许情况下,应尽量增加翻耕深度;秋季水田土壤含水率较高,对动力要求高;秸秆根茬高度宜控制在25~35 cm之间;秋季翻耕作业应采用高速档位匀速前进。
On the basis of mechanized subsoiling technology in paddy field,the feasibility of subsoiling operation model was verified by comparative test.The results showed that:The ploughing depth should be increased as much as possible under the permission of agriculture;The soil moisture content of paddy field in autumn is high,which requires high power;The height of straw stubble should be controlled between 25 and 35 cm;In autumn ploughing operation should adopt high speed gear to move forward at a constant speed.
