玉米公顷产量超15000 kg配套技术研究

采用成单19为参试品种，在四川省喜德县海拔1700 m的孙水河谷冲积土壤上进行试验、采用营养土软盘育苗，定向栽培，施足底肥、配方施肥、化肥深施、防治病虫、人工辅助授粉，剔除老叶，授粉结束后，去雄花等配套技术。经实际验收，公顷产达到15235.5kg。创造了凉山州乃至四川省玉米高产纪录。

Research on Techniques of Maize Yield over 15000 kg/hm2

We adopt Chendan-19 as a trial maize variety and experiment on the alluial soil in the sunsui Valley which is 1700m above sea level in Xide County of sichuan province.We use such techniques as cultivation seedlings on nutrient soil in soft disks,oriented transplanting,supplying sufficient base fertilizer,prescribed fertilizer supplying,deep supplying of chemical feritlizer,preventing diseases and insects,artificial pollination,and excising old leaves and removing make flowers at the end of pollination.After the actual checking upon delivery,the yield reaches 1015.7kg per mu which sets up the high-yielding record in Liangshan region on even throughout Sichuan province.
