For example, plant K content in seedling stage is usually less than 3 %, while during the period from plant transplanting to maximum tillering stage, plant K content reaches to a peak value (more than 4%), high K content in this period is favorable for ph

比如，苗期植株含钾量通常低于3%，从植株移栽至最大分蘖期达到峰值（大于4%），这一阶段高含钾量有利于光合作用。
