Description
Technical field
This utility model relates to a kind of hami melon Maturity acoustics the cannot-harm-detection device.
Background technology
Hami melon is characteristic melon and fruit and the national geography famous special product in Xinjiang, and the cultivated area of hami melon quickly increases in recent years
Adding, 2002-2009 Annual planting area is from 2.60 ten thousand hm2Rise to 8.67 ten thousand hm2.But, on market, the hami melon quality good and the bad is not
One, reduce overall price.Its reason has: the hami melon quality that in (1), ground is introduced a fine variety in a large number is low, but is turned on Xinjiang " hami melon "
Plate, affect the reputation of Xinjiang fine work hami melon；(2) Xinjiang melon grower is in order to seize morning market, or adopts when five, sixty percent is ripe
Pluck, or use " ethephon " etc. to accelerate the ripening, make inferior hami melon come into the market, adulterate；(3) due to horticultural management water
Flat height is different, and same melon patch quality hami melon quality also has larger difference.The identification of tradition hami melon Maturity is mainly by seeing
(reticulate pattern and color), hear (fragrance), by (soft or hard), but fatiguability and testing result are big by subjective impact；Fruit durometer and sugar
Degree meter can be used to detect hami melon Maturity, but belongs to destructive detection.Therefore, the lossless inspection of hami melon Maturity how is realized
Survey, be hami melon industry problem in the urgent need to address, significant to improve commodity rate to realizing hami melon classification.
