寒地包衣玉米种子压缩特性试验研究
Experimental Study on Compression Characteristics of Cold Coated Maize Seed
摘要
Abstract
The parameters of geometrical size , the 1000-grain weight , caesural angle , glide friction angle of Long dan 47 budded seeds were tested .Three axis dimensions of length is 9.287mm;width is 7.64mm, thickness is 5.98mm, caesural angle is 32.20 degrees, glide friction angle is 25.40 degrees, the 1000 grain weight of is 369.5g.By using CTM2050 microcomputer control electronic universal material testing machine , get the Dragon Dan 47 corn seeds in the flat, upright, side discharge conditions compression curves , consistent with the PEAL-READ model by fitting curve , and obtain the maximum compression load .Results showed the seeds are more vulnerable to the impact of external compres-sion of grain in the side and stood .The flat compression load is 2 .6 times of vertical setting compression load and is 2 .7 times of the side compression load .关键词
