摘要
春玉米品种、密度、施氮量、施磷量四因素三水平试验表明,密度是影响洛南川道地玉米产量的主要因素,品种对玉米经济性状和农艺性状的改善具有显著作用。试验最优处理组合为A3 B3 C1 D2,即品种掖单19,密度6.0万/hm2,施氮量255 kg/hm2,施磷量75 kg/hm2。
The results of cultivation test of maize with varieties, density, N-fertilizer and P-fertilizer indicated that density was principal factor on the yield of maize, and varieties had important effect on the grain characters and agronomic characters. For highest yield, varieties, density, N-fertilizer and P-fertilizer of spring maize should be Yedan19, 6?04/hm2, 255 kg/hm2 and 75 kg/hm2 respectively.
