[目的]探讨氮磷钾对秋玉米产量及经济性状的影响。[方法]采用正交试验设计L4（23），3因素2水平4个处理：无肥区（CK）、无钾区（施P、N）、无磷区（施N、K）和无氮区（施P、K），分析氮磷钾对南方秋玉米产量及经济性状的影响。[结果]施氮极显著增加了秋玉米产量、穗长、穗粗、穗行数、行粒数、千粒重和出籽率，而对秃顶率无影响；施磷显著提高了秋玉米产量和穗长，显著降低了秋玉米穗行数和秃顶率，极显著降低了秋玉米千粒重和出籽率，而对稳粗和行粒数无影响；施钾则极显著降低了秋玉米穗长、行粒数、千粒重、出籽率和秃顶率，而对产量、穗粗和行粒数无影响。[结论]施氮和施磷能提高秋玉米产量，改善秋玉米的经济性状。
[目的]探討氮燐鉀對鞦玉米產量及經濟性狀的影響。[方法]採用正交試驗設計L4（23），3因素2水平4箇處理：無肥區（CK）、無鉀區（施P、N）、無燐區（施N、K）和無氮區（施P、K），分析氮燐鉀對南方鞦玉米產量及經濟性狀的影響。[結果]施氮極顯著增加瞭鞦玉米產量、穗長、穗粗、穗行數、行粒數、韆粒重和齣籽率，而對禿頂率無影響；施燐顯著提高瞭鞦玉米產量和穗長，顯著降低瞭鞦玉米穗行數和禿頂率，極顯著降低瞭鞦玉米韆粒重和齣籽率，而對穩粗和行粒數無影響；施鉀則極顯著降低瞭鞦玉米穗長、行粒數、韆粒重、齣籽率和禿頂率，而對產量、穗粗和行粒數無影響。[結論]施氮和施燐能提高鞦玉米產量，改善鞦玉米的經濟性狀。

[Objective] The aim was to study tile effects of different N-P-K levels on yield and economic traits of southern autumn maize. [Method] The effects of different N-P-K levels on yield and economic traits of southern autumn maize were studied in a [L4（23） orthogonal experiment with 4 treatments： no fertilizer （CK）, no potassium （with P and N）, no phosphorus （with N and K） and no nitrogen （with P and K）. [Result] The result showed that N very significantly increased the yield, ear length, ear diameter, row number, row grains, thousand seed weight and the rate of seed, but had no effeets on hald rate. P increased the yield and ear length, but decreased signifieantly the row number and the bald rate, and decreased the thousand seed weight and the rate of seed very significantly; but had no effects on ear diameter and row grains. K very significantly decreased ear length, row grains, thousand seed weight, rate of seed and the bald rate; but had no effects on yield, ear diameter and row grains. [Conelusion] It was suggested that applying N and P fertilizer could improve the yield and economic traits of southern autumn maize.
