摘要 以封丘县潮土为研究对象,结合当地常规施肥和不施肥(对照)处理,在大田条件下研究了在200 kg/hm2供氮水平下金阳牌有机无机肥料、金正大控释肥、红四方纳米控失肥3个新型肥料对夏玉米籽粒产量和蛋白质产量的影响.结果表明,在3种新型肥料中,红四方纳米控失肥对提高玉米产量和玉米籽粒蛋白质效果最明显,分别较常规施肥提高16.2%和18.9%;其次为金阳牌有机无机复合肥,其效果仅次于红四方纳米控失肥;最后是金正大控释肥.以上结果表明,在3种新型肥料中,红四方纳米控失肥对夏玉米增产和改善品质效果最好,而其他肥料(金阳有机无机肥、金正大控释肥)的缓控效果不能在当季显现,可能主要是由于夏玉米生育期相对较短引起的. Under field conditions, taking fluvo-aqnic soil as the experimental object soil in Fengqiu county, grain yield and protein of summer maize were studied through applying three types of new fertilizers,that is organic complex fertilizer (OMF) of Jinyang, controlled release fertilizer (CRF) of Kingenta and controlled loss fertilizer (CLF) of Redsifang, respectively. There was the same amount of nitrogen (N) application with 200 kg/hm^2 in each fertilizer treatment. Result showed that grain yield and the protein yield of maize grains were increased by three fertilizers application. In all experiment treatments, the CLF treatment could better increase the yield and the protein yield of maize grains than that of the other fertilizers, and its grain yield and protein yield were 16.2 % and 18.9 % higher than the conventional fertilizer application, respectively, and the second was OMF, the last was CRF. In conclusion, comparing with control and conventional treatment, maize grain yield and protein could be increased by three new type fertilizers application,especially the CLF with the highest yield and protein yield mainly due to fast nutrient release of the CLF in accordance with mass nutients use during short growing period of summer maize.
