Abstract: To solve the problem of how to improve garlic yield in applying different amount of organic fertilizer. We have studied the effect of applying‘Jinmanyi’(a name of an organic fertilizer) to the garlic‘Yu 5th’, adopting the method of combing field trials and laboratory experiments, in which used‘Yu 5th’garlic and‘Jinmanyi’as test materials. The test showed that the application of different amount of‘Jinmayi’(a name of an organic fertilizer) on garlic had a significant influence on the yield of garlic bulb and garlic sprouts. Compared with single application of fertilizer, single application of organic fertilizer on garlic yield decreased garlic bulb and garlic sprouts, respectively by 40.1%, 37.78%. With equal amount of application with organic fertilizer and fertilizer, the former always yields higher than the latter, of which the increase rate of garlic bulb was 2.4%-10.1%, and the increase rate of garlic sprouts was 3.19%-9.85%. Therefore, garlic that applied with different amount of‘Jimanyi’had prominent economic benefits. Besides, the application of different amount of‘Jimanyi’had a great effect on soluble solids. After applying organic fertilizer to garlic, the garlic bulb and garlic sprouts contain much higher soluble solid, respectively 1.94%-7.38%, 3.43%-12.72%, compared with single application of fertilizers, increased the number of yellow blades and decrease the number of green leaves. Compared with the application of pig manure,‘Jimanyi’had little influence on total number of blades of garlic but had great effect on its yield of garlic bulb and garlic sprouts. The comprehensive test showed that the application of‘Jimanyi’with 6000 kg/hm² would receive the highest economic income, which was a relatively desired fertilizer amount.
