Abstract：Citrus Gonggan is the main cash crop in Deqing County and the surrounding area, but anthrax and abnormal climate oftten lead to bad effects on its production and farmers income. To explore the amino oligosaccharins's function on Gonggan's disease prevention, yield increasing and quality improving, a field test about amino Oligosaccharins on Gonggan was carried out. Oligosaccharins-spraying 1000 times dilution treatment was used on the period of spring sprouting, bloom stage, flourishing florescence and physiological fruit-falling of citrus gonggan with routine management, and the routine management as control. The results showed that the number, weight and colour of young fruit leaves with treatment was signficiantly better than that of routine management. The incidence of anthrax of oligosaccharins-spraying and routine management are about 1.4% and 10.3% separately, per fruit weight are 108.17g and 86.85g separately, the weight gain rate increase to 24.55%. The fruit surface is smooth and uniform coloring with Oligosaccharins-spraying treated, thus the fruit quality is improved. The acidity degrade by 12.05%, the content of Vc rise about 29.74% with Oligosaccharins-spraying treated, which are significantly different through square error analysis. The tests illustrated that Oligosaccharins treatment can improve disease resistance and the quality of the compound, and the production was increased.
