摘要
为推进辽西地区机械化旱作农业的发展,介绍鸭嘴式膜上打孔播种机的总体设计思路,并对机具性能进行田间试验。试验结果表明,该机平均播种深度为7.23 cm,变异系数为9.0%;平均穴距19.6 cm,变异系数为3.9%,符合机械化保护性耕作的要求。
In order to promote the development of dry farming in West Liaoning, this article gives a description of the structure design of the duckbill type film punch planter, and field tests were conducted on the equipment performance. Experimental results show that the machine sowing depth averaged 7.23 cm, the variation coefficient was 9.0%; the average hole spacing of 19.6 cm, and the coefficient of variation was 3.9%, all consistent with the requirements of mechanized conservation tillage.
