吉林省吉安市凉水乡农科站1990年在海关村进行了10亩地的玉米去雄试验,去雄后的玉米叶色浓绿,茎秆增粗,叶片功能期延长6～7天,雌穗抽丝期提前2～3天,提早成熟6～7天,果穗增长,穗粒数和百粒重都有明显增加。秋后测产,亩增产玉米52公斤,比对照增产10.5%。玉米去雄是一项简单易行的增产措施。因一个雄穗能产生1.5～3亿个花粉粒,而一个雌穗一般只有500～1000朵小花,花粉量供大于求。因而去雄后
Ji’nan City, Jilin Province Liangshui agricultural station in 1990 in the customs village of 10 acres of maize to male test, to masturbate corn leaf color dark green, stem thickening, leaf function extended 6 to 7 days, female Spike silk stage 2 to 3 days in advance, early maturity 6 to 7 days, ear growth, grain number per spike and 100-weight have increased significantly. Measured after the autumn, acres of corn yield 52 kg, 10.5% more yield than the control. Maize to male is a simple and easy stimulation measures. Because a tassel can produce 1.5 to 300 million pollen grains, while a typical ear is only 500 to 1000 flowers, the amount of oversupply of pollen. So to male after
