Abstract: In order to explore the effect of organic fertilizer with Bacillus natto on crop growth and increase the resistance of crops on basal stem rot microbe Rhizoctonia solani,organic fertilizer with fish viscera was produced using Bacillus natto as fermental and functional microbe. The final fertilizer was utilized in the experiment of testing crop' s resistance to R. solani:seeds of tomato and pepper were respectively sowed in garden soil and garden soil with infected R. solani,and the growth of which were compared. B. naato and R. solani were cultivated in petri dish for their confrontation. The results revealed that there was no significant effects of the final organic fertilizer on the germination of both seeds. In two groups of garden soil with fertilizer,both of tomato and pepper growth were nearly 3 times of that in garden soil without fertilizer. In the infected garden soil without fertilizer,the percentage of basal stem rot for tomato and pepper seedlings were 55% and 50% respectively;while in the infected garden soil with with fertilizer,the percentage of basal stem rot for them were respectively 11% and 17%. Bacterial colony on confrontation of B. naato and of R. solani in petri dish showed that R. solani was inhibited. Overall,the above result indicated:R. solani was inhibited by B. natto,and the growth of tomato and pepper was enhanced by the organic fertilizer produced with B. natto fermentation,and the percentages of basal stem rot for tomato and pepper seedlings decreased.
