摘要:
在玉米正常收获期间,明确器官含水率、力学强度和机收质量的变化规律,探明影响籽粒机收效果的直接因素,对实现玉米籽粒机收和提升机收质量具有重要意义.本试验以两个不同熟性品种为材料,采用半喂入式籽粒收割机,开展分期收获的田间试验研究.结果 表明,籽粒静态压碎强度(耐破碎性)和籽粒与穗轴连接强度(易脱粒性)分别与籽粒破碎率形成了直接的因果关系,两者同是影响破碎率的关键因素.籽粒压碎强度(x)与破碎率(y)可高度拟合为二项式回归关系(R 2=0.8827,P
摘要(英文):
This research studied the role of selected mechanical properties of grain and cob (in particular grain crushing resistance and the detachment resistance of grain on the cob) and plant and cob moisture content in determining suitability for machine harvesting in feed maize. This information is important for improving harvest outcomes for feed maize crops in Southwest China. An early and a late maturing cultivar were tested. The experiment involved a mechanical harvester and a large field study. It was found that the grain crushing resistance (CR...
