摘要
为获得优质高效的肥料精量化施撒效果,本研究以橡胶专用颗粒肥为对象,采用响应面设计试验与分析方法,研究了橡胶专用颗粒肥在含水率、跌落高度和碰撞接触面3因素交互作用下对肥料跌落后反弹高度响应结果的影响。结果表明,3因素交互获取最佳的响应值组合为跌落高度49.36 cm,2 cm厚塑料板,8.93%的肥料湿度,经平行试验验证并获得橡胶专用颗粒肥与塑料板、钢板和肥料平铺面的恢复碰撞系数分别为0.72、0.64和0.41;各因素对肥料反弹高度的影响大小顺序为碰撞材料A>肥料含水率C>跌落高度B,AC的交互作用和二次项A2水平显著,随着碰撞材料A发生变化,反弹高度呈塑料板(‒1)>钢板(1)>肥料平铺面(0)响应趋势。上述结果对于肥料颗粒运动仿真分析、适配的农机具原理分析、主要结构设计和用料选型以及橡胶专用颗粒肥的物化特性持续优化均具有重要的实际指导意义。
The effect on the response of fertilizer rebound height after the interaction of three factors of rubber special granular fertilizer in moisture content,drop height and collision contact surface was studied by the response surface design test and analysis method to obtain a high-quality and high-efficiency fertilizer fertilization effect.The prediction results showed that the best response value combination obtained after the interactive experiments of the three factors was a drop height of 49.36 cm,a 2 cm thick plastic plate,an 8.93%fertilizer humidity.The results were verified in parallel experiments and a recovery collision coefficient of rubber-specific granular fertilizer with the plastic plate,steel plate,and fertilizer tile.It was 0.72,0.64 and 0.41 respectively.The conclusion of the analysis was that the effect of each factor on the rebound height of the fertilizer was in the order of impact material A>fertilizer moisture content C>drop height B.The interaction of AC and the second term A2 level was significant.As the collision material A changed,the rebound height showed a response trend of plastic plate(‒1)>steel plate(1)>fertilizer tile surface(0).The results have important practical guiding significance for the simulation analysis of fertilizer particle movement,the analysis of suitable agricultural machinery principles,the main structural design and material selection,and the continuous optimization of the physical and chemical characteristics of rubber special fertilizer.
