最终单株总干物分配（％），麻骨４０．２、叶片１９．４、花器１６．４、原麻１４．０、麻壳８．１、叶柄１．８；各器官干物量对单株总干物量的直接通径系数，花器＞麻壳＞麻骨＞叶柄＞原麻＞叶片。在生育后期，叶片、叶柄和花器含Ｋ率降低，麻骨中则升高，高产品种原麻含Ｋ率也升高；各器官最终含Ｋ率，麻壳＞叶柄＞麻骨＞花器＞原麻＞叶片；麻壳、麻骨和原麻含Ｋ率与原麻产量呈显著正相关。Ｋ回报系数生育后期降低。高生物量、高产量、高耗Ｋ品种（如细叶青）在Ｋ肥充足条件下具有生产优势；中、低生物量和原麻产量、低耗Ｋ类型（如黄壳铜、竹子麻等）品种可作为耐低Ｋ资源利用
Total dry matter distribution of the final plant (%), Scutellaria biloba 40.2, leaf 19.4, flower 16.4, the original hemp 14.0, hemp 8.1, petiole 1.8; Direct path coefficient of total dry matter, flowers> Ma> Mau bone> petiole> the original hemp> leaves. In the late growth period, the K content of leaves, petioles and flowers decreased, while the content of K in high-yielding varieties also increased, while the K content in the high-yielding varieties also increased. Hemp> leaf; K contain rate of hemp, hemp bone and original hemp was significantly and positively correlated with the yield of raw hemp. K coefficient of return lower late childbirth. High biomass, high yield, high consumption of K varieties (such as fine leaf green) in the K adequate conditions have production advantages; middle and low biomass and crude output, low consumption K type (such as yellow shell copper, bamboo hemp, etc. ) Varieties can be used as low-K-resistant resources
