Abstract: 玉米移栽不但能够大幅度的提高产量,而且能够提高玉米品质,确保国家粮食安全.通过近年来的玉米纸筒育苗、机械移栽情况看,效果不太理想.下面,我就玉米育苗、机械移栽技术探讨如下: 一、育苗和苗期管理 1.品种的选择及处理.(1)品种选择:移栽的目的就是通过棚室育苗,延长玉米生育期,增加有效积温,达到增产的目的.所以品种的选择很重要,应当选择比当地生育期晚10 ~ 15天,或有效积温多200~250℃的品种,发挥品种的增产潜力.(2)种子处理:在播前10 ~15天,选择晴朗微风的天气,把种子放在阳光下连续晒2天,用35%的多克福种衣剂,按药种比1:70进行种子包衣,防治苗期地下害虫.
