Abstract:
With self-made beer sludge compost and seedling of apple as test materials，to analyze the short-term effect of beer sludge compost application of different contents (25，50，100，200 g/kg，code of treatment BSC1，BSC2，BSC3，BSC4) on apple seedling roots growth，physiological characteristics and heavy metals enrichment.By the potted split-root planting way，the effect of beer sludge compost discussed about different contents on apple seedlings root heavy metals enrichment，antioxidant enzymes (SOD，POD，CAT)，and other physiological characteristics and the root morphology.The results showed,each treatment on both sides of the partition root growth，physiological characteristics and heavy metals enrichment were different，the enrichment contents of heavy metals Cr，Zn，Cu and MDA in root were positively correlated with the applying content of beer sludge compost，and significantly higher than the corresponding control on the other half.Along with the applying of beer sludge compost content increased，root morphology，antioxidant enzyme and root activities were showed a trend of increased and then decreased.BSC1，BSC2 and BSC3 could significantly promote the root growth and increase the underground biomass，and each treatment application of sewage sludge compost were 1.40，1.69，1.24，1.69 times to the corresponding control in the other half.For the apple seedlings root SOD activities，BSC2＞BSC1＞BSC3＞BSC4.Compared with the corresponding in the control of the other half，the apple root CAT activities of BSC1，BSC2 and BSC3 were respectively higher 28.78%，82.25%，25.57%，and BSC4 was 24.22% lower than CK4，including BSC2 was significantly higher than BSC1，BSC3，BSC4(P＜0.05)，BSC3 and BSC1 were no obvious difference.There were role in promoting on the apple root POD activities with different applying contents，which were respectively 1.41，1.83，1.42，1.14 times to the corresponding in the control of the other half，and the difference significant(P＜0.05).In this experiment，the effect of apple seedlings root growth were different with the beer sludge compost application rate，as a whole，the root was not produced the enrichment phenomenon of heavy metals and MDA about 50 g/kg beer sludge compost，and which could promote root growth，enhance antioxidant enzyme and root activities.
