玉米去雄是一项简而易行的增产措施。据试验去雄比不去雄的一般增产10—13％以上,所以有句农谚“玉米去了头,力气大如牛”。玉米去雄增产的原因是,玉米在不同的生长阶段,植株的生长中心不同,营养物质的分配也就不一样。拔节前,根、茎、叶是生长中心,消耗的养分占整个植株的80％,拔节到雌穗开始分化,根茎叶和雌、雄穗消耗的养分各占二分之一,基本是平衡
Maize to male is a simple and easy stimulation measures. According to the test to increase the male than the general increase of more than 10-13%, so there is a saying of agriculture “corn went to the head, great strength.” Maize to male growth of the reason is that corn in different stages of growth, plant growth centers are different, the distribution of nutrients is not the same. Before jointing, the roots, stems and leaves are the growth centers. The consumed nutrients account for 80% of the whole plants. The stems begin to differentiate after jointing and jointed. The nutrients consumed by root, stem,
