摘要
对仁用杏林生物量及9种营养元素生物循环的研究结果表明:仁用杏林(4年)生物量为5.7849t/hm2。不同器官营养元素含量差异较大,N、P、K、Mg的含量叶中最高;Fe、Zn、Cu、Mn的含量吸收根中最高;不同营养元素吸收、存留、利用排序相同,归还排序不同。
he biomass and nutrient cycle of nine elements in the apricot stand for the almond have studied. The results show that the biomass of the stand (4-years) is 5.7849t/hm2. The divergence for content of nutrient element in different organs is larger, and the content of N,P,K,Mg in the leaves is highest and the content of Fe, Zn, Cu, Mn in the absorb roots is also highest. The arrange sequence for absorbent, existent and utilization of the different nutrient elements is same, but the arrange sequence for returning of them is different.
