一种关于多粒穴播的成穴性能检测方法的研究
The Research of Detection Method about Multi Grain Bunch Planting's Hole Forming Performance
摘要
Abstract
The quality of the hole forming of hill-drop drill which adopts ditching sowing is determined by the number of seeds released by the seed metering device at once and a variety of factors in the whereabouts of millet .Some factors are uncontrollable factors , the distribution of seeds in the seed ditch cannot be determined .Therefore , if we want to assess the performance of the seeding machine , there is a problem that can not be avoided , that is , how to measure the point formation and hole distance .At present , there is a national standard determination of single grain seeding performance , but not have multi grain bunch planting determination standard .In this paper , the hole size ( seed group longitudinal length),the number of points, and the distance of the points of the 2BXQ-6 type millet sowing machine were defined, and the basis for determination is according to the performance requirements of agricultural expert on millet multi grain bunch planting .In this paper , the sowing data samples were analyzed by using the cluster analysis in mathematical statis-tics and combining with the professional statistical software , and according to the analysis results to determine the per-formance of multi grain planting and put forward a detection method about hole forming performance of multi grain seed .关键词
