桃树机械疏花试验与分析

Experiment and Analysis of Peach Mechanical Flower Thinning

机械疏花是果园机械化生产的重要环节,而疏花机构的运行参数是影响疏花效果的关键因素。为此,采用正交试验方法,分析了单根疏花绳的材质、长度、直径和电机转速等因素的不同水平对冲击力和桃树疏花效果的影响,并通过试验结果的极差和方差分析得到疏花绳材质是影响冲击力的显著性因素,疏花绳直径既是影响冲击力和疏花率的首要因素也是显著性因素。研究表明:冲击力越大,疏花率越高,作业效果越好。进一步试验得到桃树疏花的最优参数组合:疏花绳材质为尼龙,直径为2mm,长度为50mm,电机转速为300r/min。

Mechanical flower thinning is an important part of orchard mechanized production.The operating parameters of flower thinning mechanism are the key factors affecting the effect of flower thinning.In this paper,the orthogonal test method is used to test the effects of different levels of factors such as the material,length,diameter and motor speed of a single flower thinning rope on the impact force and peach blossom thinning effect.Through the range and variance analysis of the test results,it is concluded that the material of the flower thinning rope is the significant factor affecting the impact force,and the diameter of the flower thinning rope is the primary factor and also the significant factor affecting the impact force and the flower thinning rate;The research shows that the greater the impact force is,the higher the flower thinning rate is,and the better the operation effect is;Through further tests,the optimal parameter combination of peach blossom thinning is obtained as follows:the material of peach blossom thinning rope is nylon,the diameter is 2mm,the length is 50mm,and the motor speed is 300rpm.
