【摘要】 本文在分析我国化肥施用以及存在问题的基础上,从分步实施精确农业的思想出发,分别进行了手控交量施肥机和自控变量施肥机的研究。重点阐述了手控交量施肥机的工作原理及关键部件设计,试验表明,该机施肥量调节方便,性能稳定,有应用前景。最后,简介了能够实现精确农业意义上的自动变量施肥系统。本文是精确农业智能机具研究的初步尝试,对我国精确农业的发展具有实际意义。更多还原

【Abstract】 In this paper, the variable rate fertilizer applicators of hand controlling (VFAH) and that of automatic controlling (VFAA) are investigated, under the consideration to practice the idea of precision agriculture (PA) progressively and solve the problems of the inappropriate using of the fertilizer in our country. The working principle and key components of the VFAH are set forth. Experiments show that the adjusting of the VFAH is convenient and its performance is steady. At last, a kind of VFAA that can satisfy the requirement of PA is introduced. The research of this paper is a preparatory work of the study on the aptitude machine of PA. It will make a significant contribution for the development of PA in China.更多还原
