通过对麻株不同生育期各器官N、P、K及有机碳的测定发现:N在叶片中的分布最多,韧皮部次之而麻骨中为最低。随着生育期的推进,各部位的N含量由于麻株对其的稀释效应而呈下降趋势。叶片下降缓慢,而韧皮部和麻骨下降较快,在氮肥不足的情况下表现更为突出。而P、K在麻株体内分布相对较均匀,消长速度较缓慢。有机碳以骨>皮>叶,并且其含量受外界因素影响不大。通过对C/N的分析发现,五裂叶前麻株以N素代谢为主,而五裂叶后则以碳代谢占主导地位,为此,在五裂叶前施重肥并适当增施N肥,对红麻的高产稳产有着极其重要的意义。
Through the determination of N, P, K and organic carbon in different organs of Hemp at different growth stages, it was found that the distribution of N was the highest in leaves, followed by the phloem and the lowest in Bone. With the promotion of the growth period, the content of N in each part showed a downward trend due to the dilution effect of hemp strain. The leaves decreased slowly, while phloem and numb bone decreased rapidly, under the condition of insufficient nitrogen fertilizer more prominent. However, the distribution of P and K in hemp was relatively uniform and the growth and decline rate was relatively slow. Organic carbon as bone> skin> leaf, and its content is not affected by external factors. Through the analysis of C / N, it was found that the N genera predniferae were predominantly N-metabolized, whereas the Corynebacterium tenuiflora was dominated by carbon metabolism. To do this, N fertilizer, kenaf yield of high yield is extremely important.
