摘要
选择兰考县玉米种子市场上有代表性、当地栽培面积较大、该区域主推的5个玉米品种(厚启321、富豫369、厚启501、金北516、登海605)进行大田试验,在拔节期、抽雄期、灌浆期、成熟期进行采样,通过对供试玉米品种不同时期株高、茎粗、干物质积累量、氮磷钾养分含量、千粒质量、产量等指标进行测定和分析,研究不同玉米品种农艺性状、养分吸收和产量的差异,以筛选适合当地种植的高产玉米良种。结果表明,厚启321和登海605这2个品种成熟期地上部干物质积累量较大,分别为16492.60、15911.85 kg/hm^(2)。成熟期,厚启321地上部氮素累积量较高,为11.67 kg/hm^(2);厚启321、金北516和登海605地上部磷素累积量较高,分别为4.25、3.98、3.78 kg/hm^(2);厚启321和登海605地上部钾素累积量较高,分别为27.94、27.67 kg/hm^(2)。厚启321产量最高,为11984.20 kg/hm^(2),之后依次为登海605、金北516、厚启501、富豫369,产量分别为11965.13、11299.61、10900.58、9826.45 kg/hm^(2)。通过对比不同品种的农艺性状、养分吸收和产量,发现厚启321和登海605的丰产指标较好,可以作为高产、高效优良玉米品种在兰考县进行推广,金北516、厚启501、富豫369相对来说略差一些。
In this paper,Five maize varieties(Houqi 321,Fuyu 369,Houqi 501,Jinbei 516,Denghai 605),which were representative in the maize seed market of Lankao County,had a large local cultivation area and were mainly promoted in the region,were selected for field test.Samples were collected at the stages of joint,despatch,filling and maturation.By measuring and analyzing the plant height,stem diameter,dry matter quantity,nitrogen,phosphorus and potassium nutrient content,thousand-grain weight and yield of different corn varieties in different periods,the differences of agronomic traits,nutrient absorption and yield of different corn varieties were studied,so as to screen the excellent corn varieties with high yield suitable for local cultivation.The results showed that the above-ground dry matter of Houqi 321 and Denghai 605 at maturity was higher,which was 16492.60 kg/ha and 15911.85 kg/ha,respectively.Houqi 321 had higher above-ground nitrogen accumulation(11.67 kg/ha),and Houqi 321,Jinbei 516 and Denhai 605 had higher above-ground phosphorus accumulation(4.25,3.98,3.78 g/ha),respectively.The varieties with higher above-ground potassium accumulation were Houqi 321(27.94 kg/ha)and Denghai 605(27.67 kg/ha).The highest yield of Houqi 321 was 11984.20 kg/ha.The yield of Denghai 605 was 11965.13 kg/ha,Jinbei 516 was 11129.61 kg/ha,Houqi 501 was 10900.58 kg/ha,and Fuyu 369 was 9826.45 kg/ha.By comparing the differences of agronomic traits,nutrient absorption and yield of maize varieties,it was found that,Houqi 321 and Denghai 605 had better yield indexes,and could be promoted as excellent maize varieties with high yield and high utilization rate.Jinbei 516,Houqi 501 and Fuyu 369 were relatively worse.
