Organic-inorganic granular fertilizer made of chicken manure powder plus N,P, K chemical fertilizers and microelements B,Zn, Mn, et al. was convenient for storage,transport and application. Experiments on 5 formulas of organic-inorganic granular fertilizer for 4 vegetable species were carried out. The result showed that the formula 2 in which B was included should be the optimum formula for the vegetable growth. The fertilizer formula 2 was then applied to autumn cabbage, autumn cucumber and white gourd in application amount experiments. The results showed that 337. 5 kg/hm2 was the rational application amount of organic-inorganic granular fertilizer for the vegetable growth among the application amounts tested(0,112. 5, 225,337. 5, 450 kg/hm2). This study indicated that some microelements,especially B,included in the organic-inorganic granular fertilizer were the major factors in the increase of vegetable yield. This correspond well to the results obtained from the soil microelements investigation in some vegetable areas.
