Improved Design and Experiments of Rice Transplanter in South Double Cropping Rice Region
摘要
Abstract
In view of the problems of machine-transplanted row spacing is too large , and the number of planted hills is insufficient , it can't give full play to the yield potential of machine-transplanted in south double cropping rice region .A 2ZS-488B(264 mm row spacing)rice transplanter was designed and tested in the paddy field by refitting transplanting arm housing , seedling box , bracket ( includes left and right bracket and the middle bracket ) and kickboard by the ap-proach of mechanical optimum design method and agronomic techniques based on the 300 mm transplanter structure in south double cropping rice region .Field experiments were conducted in Jiangxi province in 2012 and 2013, involving different rice cultivars and two row spacing .The result showed that the machine had stable properties , the floating rate , injury rate and missing rate of rice seedling is 1 .47%,2 .41%and 1 .70%, and qualification rate of relative uniformity is 89.54%, respectively.The yield average increased 529.43 kg/hm2 , and average increase yield rate by 8.57%more than 300 mm row spacing .The research provides a research of machine-transplanted in south double cropping rice re-gion.It is conducive to the effective fusion of agricultural machinery and agronomy .关键词
