小冠花硬实种子破皮处理工艺参数优化

Process parameter optimization of breaking treatment for hard seed of Coronilla varia L.

为了解除小冠花(Coronilla varia L.)种子硬实,根据小冠花种子的基本特征设计了硬实种子破皮处理机。通过因素二次正交旋转回归试验,考察了破皮盘间隙、差转速、下破皮盘转速对硬实种子处理的影响,得出试验指标与影响因素的回归模型。结果表明,破皮盘间隙和差转速对处理的影响极显著(p<0.01),下破皮盘转速对处理的影响显著(p<0.05);硬实种子处理的最佳工艺参数是破皮盘间隙为2mm,差转速为74r/min,下破皮盘转速为128r/min。研究结果为解除小冠花种子硬实提供了技术指导。

In order to break the hard seed of Coronilla varia L.,the hard seed breaking machine was designed according to the major characteristics of Coronilla varia L.seeds.With three-factor quadric orthogonal regression composite experimental design,the influences of the space between two plates,the rotational speed difference between two plates and the bottom plate rotational speed were investigated,and the regression equation was obtained.The results showed that the effects of space and rotational speed difference between two plates on experimental target were extremely significant（p〈0.01）,and the effect of the bottom plate rotational speed on experimental target was significant（p〈0.05）.The optimum process parameters were as followed：2 mm between two plates,74 r/min of the rotational speed difference between two plates,128 r/min of the bottom plate rotational speed for the breaking-machine.These results can provide technical guidance for the breaking hard seed in Coronilla varia L..
