收获后花生植株力学特性研究

Research on Mechanical Properties of Post-harvest Peanut Plants

花生植株力学特性对挖掘、去土、输送和放铺等环节有重要影响。为提高花生收获机的生产率,以3种辽西地区主栽花生品种为对象,应用万能材料试验机研究含水率对花生收获后植株力学特性的影响规律。试验结果表明:在相同的含水率下收获摘果时,柄果接点更易断裂;花生品种对秧柄接点及柄果接点的拉力均影响显著。

The mechanical properties of peanut plants have significant effect on damage in digging, clearing soil, transport and laying down process. In order to improve the efficiency of peanut harvester and reduce the damage, three varieties of peanuts cultivated in west Liaoning was selected to study the effect of moisture rate on plant mechanical properties with universal material testing machine. The resuits show that under the condition of same moisture rate, peduncle node is more likely to be fractured while being harvested; and peanut varieties have a significant effect on both seedling node and peduncle node.
