什么是小麦的分蘖和分蘖节? “分蘖”是专指禾谷类作物植株基部所发出的分枝(侧茎)而言(“分蘖”这个词也可作为动词来用,就是指发生侧茎的过程,即农民所说的“棵(木义)”)以小麦来说,当幼苗出现三片叶子以后不久,就可以看到在第一片叶的叶鞘内露出分枝的顶端,它是由第一叶叶鞘基部的腋芽萠发来的,这就是分蘖。随后顺次从第二叶、第三叶的叶鞘伸出第二与第三个分蘖。这些分蘖都是从主茎上生出的,称为第一级分蘖。如果条件适合,第一级分蘖也可再生出分蘖,就叫第二级分蘖。依此类推,甚至可以生出第三级、第四级以至更多级的分蘖,使一株麦苗形成一个密集的株丛。 What is the tillering and tillering of wheat? “Tillering” refers to the branching (stems) that occur at the base of plants that specifically refer to cereal crops (the term tillering is also used as a verb to refer to the occurrence of lateral stems The process, which the farmer calls “tree (woody)”) In wheat, shortly after the emergence of three leaves in the seedling, one can see that the top of the branch is exposed in the leaf sheath of the first leaf, The axillary buds of the first leaf sheath base send hair, which is tillering. Subsequently, the second and third tillers are extended from the leaf sheaths of the second leaf and the third leaf in turn. These tillers are born from the main stem, known as the first-level tillers. If the conditions are right, the first level tiller can also be regenerated tiller, called the second level tiller. By analogy, it is even possible to produce tillers from the third, fourth and even more levels so that a single wheat seedling forms an intensive plant cluster.
