在大田常规施肥条件下，通过对不同熟期的三个青花菜品种从移栽到收获植株养分吸收和干物质积累特性的分析和测定表明：青花菜一生中对各营养元素的最大吸收量顺序由于品种熟期不同而稍有差异，每生产1000kg青花菜吸收的N、P、K、Ca和Ma量分别为1545～20.06kg、1.45～2．51kg、8．98～10．87kg、7.32～9．48kg和1．65～2．40kg；青花菜的吸肥高峰出现在花球形成时；不同器官干物重占植株最大干重的比例顺序均为叶＞花球＞茎＞根，早熟品种玉冠的花球所占比例较高。
Under routine fertilization conditions in the field, analysis and determination of nutrient absorption and dry matter accumulation characteristics of three broccoli cultivars at different maturity stages from transplanted to harvested plants showed that the order of maximum absorption of nutrient elements during the life of broccoli Due to the slight difference in maturity of cultivars, the amounts of N, P, K, Ca and Ma absorbed by broccoli per 1000 kg were 1545-20.06 kg, 1.45-2.51 kg, 8.98-10.87 kg, 9.48kg and 1.65 ~ 2.40kg respectively. The peak of fat absorption of broccoli occurred when flower bulbs were formed. The proportion of dry matter weight to plant maximum dry weight in different organs was leaf> flower ball> stem> root, Yu crown spent a higher percentage of flower balls.
