Studies On The Automatic Quality Estimation And Grading Of Grafting Seedling

With grafting developing towards multi-species , industrialization, it's essential to develop the automatic grafting skill of seedling, based on the present automatic vegetable grafting device. This subject regarded vegetable shoot as the research object, first ,obtained the effective change range of some characteristic parameter value, such as the length of cotyledon, the width of cotyledon, the area of cotyledon,etc. through the physiological and physical characteristic experiments of three daily nursery stocks of watermelon, bottle gourd and squash separately, setting up standard sample characteristic data base of nursery by inputting some characteristic parameter value stock, and offered the basic data for the sample parameter, setting up of designing the software of the nursery stock measuring; second, obtained the characteristic value of testing nursery stocks by computer vision system carrying on a series of punishments of gathering the picture of the nursery stocks, and the picture digitization and code, transformation, enhancements picture filtration and picture cutting apart, etc, before automation is grafted. The grafting shoots after testing is dealt with automatically in grades in case of comparing with the characteristic parameter value of the sample shoot. The research signification of this subject is as follows: on one hand reducing the later stage disease of the nursery stock grafting; on the other hand recording theory of characters of standard grafting seedling in database, simulating the course of people selecting shoot in grade and setting up hierarchic model, realizing the computerization of the nursery stock grades automatically, promoting the development of nursery stock from relying on traditional artificial to using computer and from experience to theoric development, improving the grafting quality of nursery stocks, and promoting the fast development of factory cultivating growing seedlings and accelerating the perfection and development of the automation grafting technology.After testing by quality nursery stocks of watermelon and bottle grourd ,by comparing with man' s inspection, the accuracy of one grade and two grade measurement can get 100%.
