Abstract: red bean also contains many trace elements and inorganic salts, such as manganese, calcium, magnesium, zinc, potassium, iron, copper and the like. Nutrition in red beans is similar to green beans, some even more than green beans. In order to popularize and promote the innovation and development of red beans and its products, choose a relatively rare red bean sprout in the market for the material, and explore its growth status in different concentrations of pure milk. use the high-quality milk, "Mengniu Deluxe" on the market treated to work as experimental material, made 4 times, 20 times, 100 times and 500 times diluted in some degree, solution while red bean sprouts which has been treated by deionized water work as the control group.
Experiments show that, from the growth point of view, 4-fold and 20-fold diluted solution exhibited a repression effect on the growth of red bean sprouts, and 4-ford one is far-gone. 500-ford and 100 fold diluted solution of milk could both promote the growth of red bean sprouts, and the promotion by 500-fold diluted solution of milk was much obvious. In view of the growth quality of red bean sprout, the nitrogen content and vitamin C content in the sprout treated by diluted milk were higher than control group. We also found a positive correlation between the nitrogen content, vitamin C content and the concentration of the diluted solution of milk. In dry weight, too.
Key word: red bean sprouts, growth, quality,pure milk, diluted solution
