摘要
违期作业造成的适时性损失是大豆经济损失重要原因之一,以海伦市为研究对象,分析该地区大豆收获作业适时性损失规律,为确定合理收获作业期提供科学依据。采用去除边界效应、相同种植管理方式等措施保证收获时间为唯一变量,依据随机区组试验法确定每日收获小区试验区内具体位置,采用罗曼诺夫斯基准则剔除异常试验数据,运用IBM SPSS Statistics 23软件分析试验数据,结果表明,试验地区大豆适时损失随收获日期呈抛物线规律变化。
One significant reason of soybean economic loss is timeliness loss, which caused by default-time operation. Taking Hailun county as research objective, timeliness loss regularities changing with soybean harvesting date were analyzed according to experiment data, which were the scientific accordance for reasonably ascertaining harvesting date. Removing boundary effect the same sowing ways and field management methods were adopted in order to control harvesting date as the only variable. Harvesting plots of each day were determined on the basis of randomized block test method. Abnormal testing data were eliminated adopting Romanowski criterion. Regularities were obtained applying IBM SPSS Statistics 23 software, which show timeliness losses were parabolic changing with soybean harvesting time.
