The experimental results show that the experimental device and detection method can effectively estimate to hatching for 5-7 days after the eggs can hatch, the accuracy rate was 93.3-94.2%. In addition, the experimental apparatus and test method is simple, economical and practical, which is in line with the actual needs of agricultural production.
