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-containing fertilizer was made by Aspergillus niger Ap-2, and the content of available phosphorus in soil was increased by 141.94% under the experimental conditions. The field experiment was conducted in the tobacco-producing area of ​​Heilongjiang province for two years. The results showed that the treatment area was Bud stage 3 to 5 days in advance, leaf maturity of 5 to 10 days in advance, the end of the harvest 15 days in advance, single leaf weight, superior tobacco ratio, the average price and other economic traits and tobacco internal quality are better than the control, saving Part of phosphate fertilizer, has produced obvious economic benefits.
