The resuIts showed that the appIication of special controI ed reIease fertiIizer for rapeseeds avoids earIy decIine of rapeseed resuIting from fertiIizer Ioss by one-off appIication, improves the number of green Ieaf before winter, and extends photosynthetic Iifespan of pods, which significantIy increases yields. What＆#39; more, with higher output-input ratio, the fertiIizer takes ad-vantages in saving cost, Iabor and increasing yield.展开更多
在大棚辣椒种植中施用宜施壮缓控释蔬菜配方肥,比当地常规施肥增产304 kg/667 m 2 、增幅6.61%;肥料投入净增152元/667 m 2 ,产值净增942.4元/667 m 2 、增幅6.77%;肥料氮磷钾配比更加协调合理,肥料利用率明显提高。总体来看,在氮磷钾...在大棚辣椒种植中施用宜施壮缓控释蔬菜配方肥,比当地常规施肥增产304 kg/667 m 2 、增幅6.61%;肥料投入净增152元/667 m 2 ,产值净增942.4元/667 m 2 、增幅6.77%;肥料氮磷钾配比更加协调合理,肥料利用率明显提高。总体来看,在氮磷钾总养分投入减少近9%的情况下,辣椒还增产6%以上,每667 m 2 净增产值近1 000元,因此该肥可大面积推广应用。展开更多

文摘通过正规的田间小区试验,研究宜施壮块茎作物专用肥在利川马铃薯上的适宜用量,成功拟合了专用肥用量与马铃薯产量的一次、二次、三次函数关系,并用二次函数计算出专用肥的最高产量用量及最佳经济用量分别为 88.1 kg/667 m 2 、77.6 kg/667 m 2 ;专用肥适宜用量有利于马铃薯干物质的积累,专用肥用量增加马铃薯的氮磷钾含量呈升高趋势,土壤有效磷、速效钾也呈升高趋势,但对土壤有机质和全氮影响不明显,化肥用量增加会增大土壤酸化的风险。
