高灌蓝莓的成熟期不一致,在3～4周时间内需要有选择地采收3～5次。现在日本的蓝莓收获方式是采用一种具有5个速度调节挡的18mm线锯对树枝进行变速振动。为了能够找到采收效率最高且采收效果最好的振动速度,利用高速摄像机对蓝莓采收过程进行记录。之后利用数据统计,回放分析采收过程中的细节,以确定最佳振动速度和振动时间。通过对5种速度的分析,发现Ⅱ挡即频率为1670次min,在果枝周围振动2s是采收的最佳方式。在这种条件下,与3个高速挡同样可以分离87%成熟的蓝莓。同时仅分离了24%未成熟的蓝莓,该结果与Ⅰ挡无显著差异。
High-intensity blueberry is not the same maturation period, in 3 to 4 weeks need to selectively harvest 3 to 5 times. Japan now harvests blueberries by using an 18mm jigsaw with five speed-controlled stops to vibrate the branches. In order to be able to find the highest recovery efficiency and the best harvesting vibration velocity, the use of high-speed video camera to record the blueberry harvesting process. After the use of data statistics, playback analysis of the details of the harvest process to determine the best vibration speed and vibration time. Through the analysis of the five kinds of speeds, it is found that the second gear, ie the frequency of 1670 times min, is the best way to harvest when vibrating around the branches. Under this condition, 87% of ripe blueberries can be separated as well as the 3 high gears. Only 24% of immature blueberries were separated at the same time. There was no significant difference between this result and that of Ⅰ.
