烟草专用生物有机肥对烤烟磷吸收·分配的影响

Effects of Flue-cured Tobacco Specific Fertilizer on Absorption and Allocation of Phosphorus

[目的]研究烟草专用生物有机肥对烤烟磷吸收及分配的影响,为黑龙江烟区生物有机肥的合理应用提供理论依据。[方法]试验于2013年在黑龙江省牡丹江烟草科学研究所(宁安)进行,共设4个处理:T1无肥处理(CK),T2当地常规施肥(烤烟专用肥),T3有机肥,T4生物有机肥。[结果]T4处理总磷积累量分别高于其他3个处理74.43%、31.43%、35.83%;T4处理的茎、下部叶、中部叶、上部叶分别比T3处理提高9.48%、29.05%、56.04%、84.81%,高于对照。[结论]T4处理对提高烤烟磷吸收与积累的效果最佳。

[ Objective ] The effects of bio-organic fertilizer on phosphorus absorption and the content of flue-cured tobacco were studied to provide a theoretical basis for the reasonable application of bio-organic fertilizer in Heilongjiang tobacco zone. [ Method] Test was carried out in Mudanjiang tobacco scientific research institute （Ning＇ an） in 2013. Four treatments were set, such as T1 no fertilizer treatment （CK）, T2 the local conventional fertilization treatment （flue-cured tobacco specific fertilizer） ,T3 the organic fertilizer treatment and T4 the bio-organic fertilizer treatment. [ Result] Total phosphorus accumulation of T4 treatment was higher than the other three treatments by 74.43%, 31.43% and 35.83%. Stem, lower leaves, middle leaves and upper leaves of T4 treatment were higher than T3 treatment by 9.48% , 29.05% , 56. 04% and 84.81%. [ Conclusion] The effects of T4 treatment was the best on the improvement of the phosphorus absorption and the content of flue-cured tobacco.
