高山冷寒区盘玉5号高产栽培技术初探

Study on High-yield Cultivation Techniques of Panyu No. 5 in Alpine Cold Region

应用2011年和2012年保基乡冷风村海拔1 600 m以上高山冷寒区域盘玉5号高产样板资料分析,结果表明:小春作物套种玉米能确保玉米3月20日前播种全苗,这样能够避过9月低温、多雨等天气,也能够降低大斑病等对于玉米产量的影响。以此利于形成高产性状,并归纳了套种作物套种玉米的高产栽培技术。

The author applied the data analysis of Panyu No. 5 high-yield model in the cold and cold area of the mountain above 1600 m above sea level in Baoji Township in 2011 and 2012. The results showed that the intercropping of corn in Xiaochun crop can ensure that the whole seedlings are planted before March 20, which can avoid the weather such as low temperature and rain in September, and reduce the impact of large spot disease on corn yield. This is conducive to the formation of high-yield traits, and summed up the high-yield cultivation techniques of intercropping crops.
