摘要

According to the measurements of the field conditions and physical parameters of ev KWS3148 sugar beet during harvesting stage,its planting mode has been established.SPSS was used to measure the main interval and frequency distribution of physical and geometric parameters for sugar beet,the relative position of sugar beet to soil has been determined,and the physical and geometric model of sugar beet was established.According to the test of the pulling force of sugar beet harvesting,the required pulling force of sugar beet under natural soil condition and the condition of the cut loosen soil on both sides by artificial have been achieved,which were (365 ± 196) and (259 ± 176) N,respectively.The pulling force was significantly correlated with the weight of root tuber and the size of the minor axis of the ellipse(P<0.0l),which is the intersecting surface of the root tuber.And it has notable bi-factorial correlations with the weight of root tuber,the maximum cross-sectional dimension and the length of root tuber at the 0.01 level.The pulling force was correlated with soil conditions,and was slightly related with the root systems of sugar beet.The test results indicated that the height of a root tuber above the ground is (60±24.4)mm,the maximum width of a root tuber is (120±28) mm,the length of the root tuber was (202±45.3) mm,the weight of the root tuber was (1198±530) g and the wedge angle of a sugar beet was (15.3°±2.14°).The established geometric model of sugar beet could provide a reference for the design of topper and harvester of sugar beet.%对收获期“KWS3148”甜菜进行田间状况和物理参数的测定,确定了甜菜种植模式.利用SPSS统计软件,得到了甜菜主要物理几何参数指标的变化区间和频率分布,明确了甜菜在土壤中的相对位置,建立了收获期甜菜的几何物理模型.通过甜菜的起拔力对比测试,得到了土壤自然状态下甜菜所需起拔力为(365±196)N,两侧松土后甜菜所需起拔力为(259±176)N.甜菜的起拔力峰值分别与块根质量、块根截面椭圆的短轴尺寸在0.01水平(双侧)上显著相关,块根质量、块根最大截面尺寸、块根长度在0.01水平(双侧)上双因素显著相关.甜菜起拔力与甜菜品种和土壤的状况相关,与甜菜根系关系不大.试验结果:块根地上高度为(60±24.4) mm,块根横向最大尺寸为(120±28) mm,根块长度为(202±45.3)mm,块根质量为(1198±530)g,甜菜的楔角为(15.3±2.14)度及甜菜的几何模型,可为甜菜的杀秧、收获等机具的设计、研发提供理论基础.
