Problems solved by technology

[0004] To measure the respiration intensity of seeds, you can measure the content of carbon dioxide, use acid titration or infrared carbon dioxide analyzer, but these two methods can not fully reflect the changes in the concentration of carbon dioxide in the air every moment, for materials with weak respiration , due to the small amount of exhaled carbon dioxide, the reaction is not sensitive, which affects the accuracy of the measurement

Abstract

The invention provides a detector capable of detecting seed vigor in batches and a detection method thereof. The detector structurally comprises a seed breathing cavity, a filter screen, a light absorption box and a spectrograph, the seed breathing cavity is located above the light absorption box, and the seed breathing cavity and the light absorption box are isolated through the filter screen; the light absorption box is square, a reflecting lens group is arranged in the light absorption box, and an incident hole and an emergent hole are formed in the side wall of the light absorption box; the transmitting end of the spectrograph is connected to the incident hole, and the receiving end of the spectrograph is connected to the emergent hole; and light enters from the incident hole, is refracted for multiple times in the reflecting lens group and then is emitted from the emergent hole. The detector disclosed by the invention can be used for detecting the seed vigor in batches, and has the advantages of small size, convenient carrying and moving and high detection accuracy.

Description

【Technical field】 [0001] The invention relates to a detector capable of detecting seed vigor in batches and a detection method thereof. 【Background technique】 [0002] Seeds are an important means of production for national survival and development, and the selection of high-vigorous seeds has a positive effect on agricultural production. With the development of technology, the requirements for the accuracy, speed and non-destructiveness of seed viability detection are getting higher and higher. The traditional germination test method is used for the detection of seed vitality. Although the accuracy is high, the test period is long and the operation is cumbersome. The conductivity test method recommended by the International Seed Testing Association (ISTA) has the characteristics of convenience and speed, but requires a conductivity tester and cannot achieve mass testing. [0003] Respiration is the main physiological characteristic of the seed itself, and all living seeds...
