    摘要:

    通过对常规露地直播栽培、比空栽培、育苗移栽、地膜覆盖4种不同玉米栽培方式的比较研究。结果表明:育苗移栽和地膜覆盖栽培使玉米物候期提前、穗部性状较为整齐、后期叶面积指数下降慢和群体质量较好,有较明显地增产效果,如果在适当的玉米收购价位,将使农户得到较好的经济效益。

    Abstract:

    The growing traits were studied and economic benefit of planting maize were compared under normal planting,interval planting,fostering seedling transplanting and plastic covering.Results of the experiment showed that the growth and development of maize were moved up by fostering seedling transplanting and plastic covering.Uniformity of ear trait was improved and the leaf area index dropped slowly in late of the season.In fostering seedling transplanting and plastic covering treatment,population structure was excellent and yield of maize was obviously improved.If the price was reasonable,maize cultivation could bring farmers more economic benefit.
