Ap-2号溶磷菌Aspergillus niger在烟草种植上的应用效果

The Applicable Effect of Ap-2 Aspergillus Niger Dissolve Phosphorus Microorganism in the Planting Tobacco

用Ap-2号黑曲霉Aspergillus niger制成磷菌肥,在试验条件下增加土壤速效磷含量141.94％,并在黑龙江省产烟区进行了两年田间试验,结果表明,处理区比对照区现蕾期提前3～5天,叶片成熟期提前5～10天,采烤终期提前15天,单叶重,上等烟比例,均价等经济性状及烟叶内在品质均好于对照,可节省部分磷肥,产生了明显的经济效益。

The phosphorus bacterium fertilizer were produced with Ap-2, Aspergillus niger, and were added into the soil, can be impel the content of the quick resslts phosphorus increased by 141.94%, in condition of the experiments and field experiment was carried out by using these the fertilizer in Hei-longjiang province in 1989 to 1990. The result indicated that date of flower bud advance 3 to 5 days compared to contrasts The date of leaf mature advance 5 to 10 days compared to contrast.The closing date of the flue-cured tobacco advance 15 days compared to contrast. The weight of single leaf, the proportion of high-quality tobacco, the average value et al properties of economy as well as internal quality of tobacco -were higher than contrast. As well cut down on part of the chemical phosphorus fertilizer as also produced economical benefits marredly.
