摘要
为了弄清成熟蓝果忍冬结合力的特性和变化规律、给机械化收获提供技术依据,在蓝果忍冬成熟期间对4个常见品种果实结合力进行了为期16天的跟踪测试。通过分析研究得出:所测试的4个蓝果忍冬品种的结合力分布在0.1~1.7 N之间(P<0.05),各品种结合力分布区间略有不同,所测试的野生阿尔泰忍冬、蓓蕾的结合力高于蓝鸟和长白山野生蓝靛果忍冬;各品种结合力随时间呈现出不同程度的下降趋势;同一天内下午的结合力显著大于上午的结合力(P<0.05);晴天与阴雨天的结合力无显著性差异。通过因子分析,可将影响结合力的因素测试时间、上下午、相对湿度、温度及天气状况转换成环境因子和时间因子。
In order to understand the characteristics of the picking force of Lonicera edulis and variation,The four common varieties were tracking test 16 days during Lonicera edulis harvest. The test results show that the picking force is mainly distributed in 0. 1 ~ 1. 7N( P < 0. 05),and the distribution range of picking force is slightly different: the test picking forces of L. caerulea subsp. altaicai and Berel are greater than Bluebird and wild L. caerulea var. edulis of Changbai Mountain,and showing vary degrees of downward trend as time. The picking force in the afternoon are significant than it in the morning of the same day( P <0.05),and no significant differences between sunny and rainy days. According to factor analysis,the factors affecting the picking force,including test time,morning and afternoon,relative humidity,temperature,weather conditions can be converted into environmental factors and time factor.
