以鲁单818为供试品种,在磷钾量相等、氮量分别为全量和80%模式下,研究了控释肥对玉米产量、土壤养分含量以及肥料利用效率的影响。结果表明,控释肥处理有助于玉米物质积累,提高玉米的产量和肥料利用率,比CK增产17.61%~24.39%,比习惯施肥增产0.59%~6.38%;全量A控释肥的产量最高,但综合衡量,本试验条件下,以控释肥A 80%施氮量即192 kg/hm2水平最为合理。
以魯單818為供試品種,在燐鉀量相等、氮量分彆為全量和80%模式下,研究瞭控釋肥對玉米產量、土壤養分含量以及肥料利用效率的影響。結果錶明,控釋肥處理有助于玉米物質積纍,提高玉米的產量和肥料利用率,比CK增產17.61%~24.39%,比習慣施肥增產0.59%~6.38%;全量A控釋肥的產量最高,但綜閤衡量,本試驗條件下,以控釋肥A 80%施氮量即192 kg/hm2水平最為閤理。

Based on the equal amount of phosphorus and potassium , Ludan 818 was used to study the in-fluence of controlled-release fertilizer on maize yield , soil nutrient contents and fertilizer use efficiency in the application mode of full and 80%nitrogen.The results showed that the application of controlled -release fer-tilizer improved the dry matter accumulation , maize yield and fertilizer use efficiency .It could increase the yield by 17.61%~24.39%and 0.59%~6.38%respectively compared with the CK and conventional fertili-zation .The maize yield was the highest when the controlled -release fertilizer A was full used .But in compre-hensive consider, it was optimum to use the controlled -release fertilizer A at 80%amount (192 kg/hm2).
