中文摘要：

通过田间试验研究了解磷生物有机肥、玉米专用有机无机复混肥和玉米缓控释专用肥对皖北夏玉米隆平206和秦龙14产量的影响,探讨了解磷生物有机肥对夏玉米产量形成的作用机制。研究结果表明,施用解磷生物有机肥可显著提高夏玉米隆平206和秦龙14的产量,供试肥料处理玉米产量大小顺序为解磷生物有机肥〉玉米专用有机无机复混肥〉玉米专用缓控释肥,解磷生物有机肥通过增加玉米穗数和穗粒数,改善玉米产量构成,提高玉米产量。皖北夏玉米肥料施用解磷生物有机肥和玉米专用有机无机复混肥较为适宜。

英文摘要：

Through field experiments, the effects of phosphate - solubilizing bacteria fermented with organic fertil- izers, corn special organic -inorganic complex fertilizers, corn special slow/controlled release fertilizer on yield formation of summer maize in North of Anhui Province were studied, the mechanisms of phosphate - solubilizing bacteria fermented with organic fertilizers on summer corn yield formation were discussed. The results were as follows. Application of phosphate - solubilizing bacteria fermented with organic fertilizers could significantly improve the yields of summer corn Longping 206 and Qinlong 14. The order of corn yields of the tested fertilizers is phosphate -solubilizing bacteria fermented with organic fertilizers 〉 corn special organic - inorganic complex fertilizers 〉 corn special slow/controlled release fertilizer. Application of phosphate - solubilizing bacteria fer- mented with organic fertilizers could improve corn yield components and increase corn yield by adding corn ear numbers and ear grain numbers.. The suitable fertilizer is phosphate - solubilizing bacteria fermented with organic fertilizers or corn special organic - inorganic complex fertilizers in summer maize cultivation in North of Anhui Province.
