摘要
为了研究微生物菌肥对冀西北坝上地区生菜田土壤酶活性及微生物数量的影响,以生菜土壤为研究对象,设置10个处理,在生菜收获时取土样测定酶活性及微生物数量。结果表明,各处理土壤细菌、放线菌数量均多于CK,真菌数量则少于CK,以底施木美土里复合微生物菌肥1 200 kg/hm2+苗期喷施育苗宝贝菌剂(浓度1∶200)(处理M2Y2)的效果最明显,其次为底施木美土里复合微生物菌肥600 kg/hm^2+苗期喷施育苗宝贝菌剂(浓度1∶200)(处理M1Y2),二者细菌和放线菌数量较CK分别增加了58.81%、63.93%和117.55%、95.91%,二者真菌数量较CK分别减少了68.98%和65.56%;土壤脲酶、转化酶和过氧化氢酶活性均以处理M2Y2最高,M1Y2次之,底施木美土里复合微生物菌肥1 800 kg/hm2+苗期喷施育苗宝贝菌剂(浓度1∶200)(M3Y2)位居第三,且三者均显著高于CK,其他处理酶活性或高于CK,或低于CK,只有菌肥和菌剂配比适宜(浓度1∶200)时,对酶活性的促进效果最好。
The investigation was carried out to explore the effects of the microbial fertilizers on lettuce soil microorganism and enzymic activity using the soil of planting lettuce as test materials, ten treatments were set up. The soil was sampled to analyze microorganism quantities and enzymic activity at harvest. The results showed that amounts of bacteria and actinomycetes in the soil of all treatments were more than CK;The number of fungi in all treatments were less than CK, and the effect of treatment of application of compound microbial bacterial manure in 1 200 kg/hm2+microbial inoculum(concentration 1 ∶200)(M2 Y2) was the most obvious, followed by the treatment of application of compound microbial bacterial manure in 600 kg/hm^2+microbial inoculum(concentration 1∶200)(M1 Y2), which amounts of bacteria and actinomycetes of the treatment M2 Y2 and M1 Y2 were increased by 58.81%, 63.93% and 117.55%, 95.91% than CK, their number of funigi were decreased 68.98%and 65.56% than CK, respectively. The soil urease and invertase and the catalase activity of the treatment M2 Y2 were the highest, M1 Y2 was the second, the treatment of application of compound microbial bacterial manure in 1 800 kg/hm^2+microbial inoculum(concentration 1∶200)(M3 Y2) was the third, and their enzymic activities were significantly higher than CK, but the enzymic activities of other treatments higher than CK or lower than CK. Only when the ratio of bacterial fertilizer and fungicide was suitable(concentration 1∶200), the promotion effect on the enzyme activity was the best.
