| 摘 要： | 为探索适宜普洱地区玉米高产栽培的优化农艺措施,以云瑞47、云优105两个玉米杂交种为材料,研究不同类型玉米品种在不同密度和不同施肥水平下产量的变化规律.结果表明：不同品种产量差异显著,在相同密度和施肥水平上云优105高于云瑞47;云优105栽培密度在82500株/hm2和施肥水平N37 kg/hm2、P2O5 225kg/hm2、K2O270 kg/hm2处理下产量最高;云瑞47栽培密度82 500株/hm2和施肥水平N375 kg/hm2、P2 O5 225 kg/hm2、K2O270 kg/hm处理下产量显著高于其它处理.

| Abstract: | In order to explore appropriate maize cultivation techniques in Pu＇er, taking Yunrui47, Yunyoul05 as test material, yield variation of different varieties under different planting density and different fertilization level were studied. The results showed that the yield of different varieties had significant difference, yield of Yunyoul05 was higher than Yunrui47 under the same planting density and fertilization level, planting density of Yunyoul05 was 82500 plants/hm2 and fertilizer level N, P2O5, K20 were 375 kg/hm2 , 225kg/hm2 , 270kg/hm2 respectively, the yield was highest; Planting density of Yunrui47 was 82500 plants/hm2 and fertilizer level N,P2O5 K2O were 375kg/hm2 , 225kg/hm2 , 270kg/hm2 respectively, the yield was significantly higher than other treatments. |
