玉米种子抗压特性及裂纹生成规律
Anti-pressing Properties and Crack Formation Law of Corn Seed
摘要
Abstract
For reducing mechanical damage of corn seed in the process of threshing and mastering the law on anti-pressing properties and crack formation of corn seed, static compresses experiment of various varieties corn seeds were carried out on LDS microcomputer control and electron draw-press test-machine. Results showed that the largest breaking power would decrease with the increasing of seed humidity ratio. The largest breaking power was the biggest with level-placing manner and in turn flank-placing manner took second place, perpendicular-placing manner was the smallest. Anti-pressing competence of various varieties corn seeds was different under same placing manners. The shape, position and law of crack in various surface loaded was different under different placing manners.关键词
