试验和生产实践证明,玉米隔行去掉植株的雄穗(即去雄),能增产8—10％。这是玉米后期管理的一项增产新技术。去雄时一定要做到适时、适量,不损伤植株。适时,就是在玉米雄穗抽出顶叶16～17厘米、花粉尚未散落,用手能够握住时去雄。适量,就是采用隔一行去一行或隔一株去一株的方式。也可隔一行去两行。但不要成片去雄。边行和田块周围应保留部分植株不去雄,否则会影响其自然授粉。雄花不发达或花粉少的应适当少去雄。植株生长旺盛,雄花发达的可以多 Experiments and production practices have proved that removing the male offspring of maize intercropping (ie, extinction) can increase yield by 8-10%. This is a latecomer management of corn new technology. Going to be sure to be timely, appropriate, do not damage the plants. Timely, that is, in the top of the corn spike out of the parietal 16 to 17 cm, the pollen has not yet scattered, the hand can hold to the male. Moderate, is to use every other line to go one line or every other way to a strain. Can also be separated into two lines. But do not become a hero. Some plants should be kept around the border and field plots, otherwise it will affect their natural pollination. Male or female less developed pollen should be less appropriate to the male. Strong plant growth, male flowers developed more
