Abstract:Our study has shown that P. corylifolia absorbs and accumulates N2 and K2O most speedily in the periods of branching, flowering and fruiting, while P2O5 in the period of full floweringand fruiting. P2O5 is accumulated mainly in the seed and K2O 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 N2, 3.68kg of P2O5 and 10.21kg of K2O is needed.
