研究表明:补骨脂N、K_2O吸收累积速度高峰在分枝期、花果盛期,P_2O_5在花果盛期;N、P_2O_5积累量主要分布在籽粒,K_2O在茎杆;其养分的积累和干物质积累成正相关;每生产100kg补骨脂需吸N 10.59kg、P_2O_5 3.68kg、K_2O 10.21kg。
The results showed that the peak accumulation of N, K_2O in podiflora was at the branching stage, the flowering stage and the flowering stage of P_2O_5. The accumulation of N and P_2O_5 was mainly distributed in kernels and K_2O in stems. The accumulation of nutrients and Dry matter accumulation is positively correlated; each production of 100kg psoralen need to absorb N 10.59kg, P_2O_5 3.68kg, K_2O 10.21kg.
