Abstract:

This experiment was conducted to explore the effect of carbendazim and bio-organic fertilizer on the apple replant disease. The Malus hupehensis Rehd. seedlings were planted in pots with apple replant soil. The effect of carbendazim combined with bio-organic fertilizer on Malus hupehensis Rehd. seedlings growth,and soil enviroment were studied. Compared with replant soil control,carbendazim,bio-organic fertilizer combined ap plication could improve root respiration rate,promote the growth of root system,improve the biomass of seedlings. The plant height and root respiration rate were increased 38% and 36% respectively. The bacterial/fungal ratios reached 19.07 times of control group of  apple replanted soil,so that it became the maximum number among the three groups. The soil fungi community structure was changed,the combined application treatment had higher simpson index and lower shannon index,pielou index and margalef index;bio-organic fertilizer,carbendazim and bio-organic fertilizer combined application had significant effects on the soil enzymes. Therefore,carbendazim and bio-organic fertilizer combined application had the better effect on apple replant disease remission.

Key words: Malus hupehensis, replant disease, carbendazim, bio-organic fertilizer
