摘要: 为了探索纳豆菌有机肥对作物的生长作用及其提高作物对茎基腐病原菌-立枯丝核菌的抗性能力,以纳豆菌作为发酵菌兼功能菌制作鱼内脏有机肥,将成品有机肥进行作物对立枯丝核菌的抗性应用实验:将番茄和辣椒种子播种于感染立枯丝核菌的园土及原园土中,对比植株在两种园土中的生长情况,并进行纳豆菌与立枯丝核菌平板对峙培养试验。结果发现,成品有机肥对两种种子发芽的作用都不明显,两种作物在两种园土中加肥组的植株生长量均达到无肥组的3倍左右,染菌园土中不加肥的番茄和辣椒苗茎基腐病苗率分别是55%和50%,加肥组的番茄和辣椒苗茎基腐病苗率分别是11%和17%;平板对峙培养的菌落状况显示立枯丝核菌生长受到抑制。结果表明,纳豆菌对立枯丝核菌生长具有抑制作用,用纳豆菌发酵制作的有机肥提高番茄和辣椒的生长量,并减少这两种作物的茎基腐病苗率。

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.
