棉花田力宝盆栽肥效研究

采用盆栽试验方法，客观评价“田力宝微生物肥料”对棉花生长发育和产量的影响．生物试验和植株养分吸收测定结果表明，田力宝能够为棉花生长提供少量磷素营养，但不能满足棉花全生育期生长的需要，本观察到田力宝的固氮微生物活性，其处理效果与施用复合肥料比较差异悬殊，与不施肥处理相当，不可能取代化肥使用．

Report on Cotton Pot Cultural Experiment Applied TLB Microbial Fertilizer

Trp Subtrop Soil Sci, 1998, 7 (3): 210 ~ 214The effects of TLB microbial fertilizer(TLB) on cotton growth and development were studied by the methed of potculture in the research. The results of both bio-experiment and nutrient elements absorbed testing showed that TLBcould supply very small amount phosphate nutrition for cotton growth, but which couldn't be satisfied its need in wholegrowth period. It wasn't observed that there was activity of fixed-nitrogen microbial in TLB. The treatment effectswere quite different between TLB and complex fertilizer, and the treatment with TLB was just equal to the contrasttreatment (no fertilizer used). TLB can,t be used as a substitute for fertilizers.
