固氮菌在白肋烟上的应用

Study on the Ultilization of Nitrogen Fixation Bacteria in Burley Tobacco

试验采用两种固氮菌肥与氮肥配合施用 ,用正交实验方法 ,探讨了各种肥料配比对白肋烟产量和产值的影响 ,结果表明 :白肋烟每株施氮 15g ,肥力高牌菌肥 2 g ,肥老大牌菌肥 1g时能获得理想的产量和产值 .

By use of orthogonal design, the author studies the effect on the yield and output value of Burley tobacco according to the proportion of different fertilizer. The result shows that when the mixture which include 25?g nitrogen, 2?g“nongdage” and 1g“feilaoda” bacteria fertilizer per stock is used, the yield and output value of Burley tobacco will be enhanced.
