| 摘 要： | 试验研究了控释肥和普通化肥对夏玉米产量、子粒品质、土壤性状以及肥料利用效率的影响。结果表明,施用控释肥有助于夏玉米干物质积累,提高夏玉米的穗粒数、容重和千粒重,比对照增产22.2%,比普通化肥增产4.3%;与施用普通化肥相比,施用等养分量控释肥更有助于提高子粒粗蛋白、可溶性糖的含量,显著提高肥料中的氮素表观利用效率、生理效率和生产效率。

| Abstract: | The experiment studied the effect on yield, grain quality of summer maize and topsoil properties about applying controlled-release fertilizer(CRF) and common fertilizer to summer maize. The results showed that applying CRF redounded to accumulate dry matter of summer maize, to increase grain kernels, volume weight, 1 000-kernels weight, and to increase yield by 22.2% than CK, 4.3% excelled to common fertilizer. Comparing with applying common fertilizer, applying CRF more improved soluble sugar content and crude protein content of grain.At one time, comparing with applying common fertilizer, applying CRF more improved apparent N-used efficiency, physiological efficiency, agronomy efficiency |
