【摘要】 为了控制一年两熟地区夏季玉米免耕播种机的施水装置在施水过程中出现的水的飞溅现象,采用了二次回归正交组合设计试验方法研究了机组前进速度、喷水口的内径和喷水口的高度对溅水范围的影响,并通过SPSS软件建立了回归方程,确定了影响因素的最优组合和相关数值。更多还原

【Abstract】 In order to control the water splash phenomenon of the summer corn no- tillage irrigating- sowing machine in double cropping area,this test uses the quadratic regression combination design to study the influence of the unit forward speed,water spout inside and height on splash area. And the regression equation was established by SPSS software,and Regression equations with SPSS,determine the optimal combination of factors and the correlation value.更多还原
