在水稻工厂化穴盘育秧播种过程中，排种器的投种过程是影响播种性能的最后环节，为满足排种器播种性能要求，对投种过程中种子运动规律、投种机理等进行了理论分析。把投种过程分为及时投种、延迟投种和强制投种过程，推导出每个过程中排种器各参数与穴盘运动速度间的关系式，并对投种过程进行了高速摄像分析，验证了理论分析的合理性。建立了型孔长度与排种器相关参数间的限制关系式，分析表明合理选择排种器设计参数，能够保证种子...
Varietal Difference and Temperature Response of Local Soil-Reduction around Germinating Rice Seed
Direct sowing Germination Rice Seedling emergence Soil reduction Varietal difference
2009/7/31
Local soil-reduction occurs around rice seed when it is sown into flooded soil, and the reduction inhibits seedling emergence. Seedling emergence is more inhibited when the reduced soil area is forme...
Development of Rice “Seed-Mats” Consisting of Hardened Seeds with a Cover of Soil for the Rice Transplanter
Cover of soil Dormancy Germination Hardening Rice Seedling Seed-mat Storage life
2009/7/21
Conventional seedling mats for rice transplanters in Japan are heavy to carry, and much labor is required to collect, wash and store the nursery boxes. In addition, seeding time overlaps with the labo...

基于蚁群算法的稻种轮廓自适应提取方法（Self-adaptive Method for Extracting Rice Seed’s Contour Based on Ant Colony Optimization Algorithm）
稻种 图像处理 轮廓提取 蚁群算法
2010/2/26
针对传统轮廓提取方法自适应能力不强的问题，提出一种基于蚁群算法的稻种轮廓提取方法。将数字图像看作一个二维网格，以稻种轮廓为蚂蚁要寻找的食物，以梯度与方向作为启发信息，蚂蚁在启发信息与信息素强度的共同引导下搜索真实轮廓。为了加快算法的收敛速度，增强蚁群的搜索能力，定义了合理的启发信息与信息素更新机制，并研究了算法中初始参数之间的关系与规律。最后，用两种光照条件下采集的图像测试该算法。实验结果表明，该...
