摘要
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。
Our study has shown that P. corylifolia absorbs and accumulates N_2 and K_2O most speedily in the periods of branching, flowering and fruiting, while P_2O_5 in the period of full floweringand fruiting. P_2O_5 is accumulated mainly in the seed and K_2O in the stem. The nutriment accumulation is positively correlated with that of dry substances. To produeo 100kg of P. corylifolia an absorption of 10.59kg of N_2, 3.68kg of P_2O_5 and 10.21kg of K_2O is needed.
