| 摘 要： | 对烟草根系施用5种配方肥料，并分别检测烟草移栽前、后20，40，60，120 d的根际土壤微生物，比较研究了不同肥料对烟草根际微生物的影响．实验结果显示：随着有机肥比例的增加，烟草根际土壤中的真菌、细菌等数量均比不添加有机肥的处理（N0处理）呈增加趋势；其中，50％无机氮＋50％有机氮处理（N3处理）能显著增加烟草根际土壤中的微生物数量，真菌、细菌、霉菌数量分别达到2．46×10^5，2．96×10^8，2．95×10^4个/g ．在烟草种植中，施用50％无机氮＋50％有机氮的有机肥有利于提高烟草根际微生物的数量．

| Abstract: | This experiment was treated with 5 kinds of different proportion of organic fertilizer in the tobacco plants ,and the microorganism of 20 d ,40 d ,60 d ,120 d rhizosphere soil were tested respectively before and after the transplanting in order to study the effect of different organic fertilizer on tobacco rhizo-sphere microorganisms .The experimental results showed that ：with the increase of the proportion of organ-ic manure ,the amount of fungi ,bacteria and mould in tobacco rhizosphere were higher than the treatment without the addition of organic manure（N0 treatment）;among them ,the treatment of 50% inorganic nitro-gen ＋50% organic nitrogen （N3 treatment ）could significantly increase the number of microorganisms in the rhizosphere soil of tobacco ,and the quantities of fungi ,bacteria and mould were 2 .46 × 10^5 cfu/g ,2 .96 × 10^8 cfu/g ,2 .95 × 10^4 cfu/g respectively .The experimental results also revealed that the application of Organic fertilizer including 50% inorganic nitrogen and 50% organic nitrogen was conducive to improving the quantity of microorganisms in tobacco rhizosphere . |
