摘　　要：研究了苹果杂种实生树营养元素含量及其相互间的关系。结果表明,在栽培条件一致、树体生长发育正常的情况下,不同品系苹果树同一种营养元素含量差异很大,其中氮、磷、钾、钙、镁、铁、锌、锰、硼的含量范围分别为1.576-2.194%、0.070-0.215%、0.51-1.78%、0.52-2.97%、0.24-0.63%、0.014-0.058%、0.001 -0.016%、0.007-0.052%、15.2-36.9 mg/kg;养分离子被苹果树体吸收时,氮和铁、锰、硼离子间,磷和镁、锌、锰离子间,钾和钙、镁、铁、锌离子间,锌和锰、硼离子间有拮抗作用,氮和磷、钾、钙、镁、锌离子间,磷和钾、钙、硼离子间,钾和锰、硼离子间,钙和镁、铁、锌、锰、硼离子间,镁和铁、锌、锰、硼离子间,铁和锌、锰、硼离子间,锌和锰、硼离子间,锰和硼离子间有协助作用。The authors studied the content and relation of nutrition element of apple(Mαλυσ) crossbreed tree. The results showed that the observably difference of the content of the same nutrition element was found among the varied varieties of apple tree in the same planting condition and common growth and developing condition, the range of content is N(1.576%-2.194%), P(0.070%-0.215%), K(0.51%-1.78%), Ca(0.52%-2.97%), Mg(0.24%-0.63%), Fe (0.014%-0.058%), Zn(0.001%-0.016%), Mn(0.007%-0.052%), 8(15.2-36.9 mg/kg) . Antagonism was showed between N and Fe,Mn,B,P and Mg,Zn,Mn, K and Ca,Mg,Fe,Zn, Zn and Mn,B,while synergism was showed between N and P, K, Ca,Mg, Zn, P and K, Ca, B, K and Mn,B, Ca and Mg, Fe, Zn,Mn,B, Mg and Fe,Zn,Mn, B, Fe and Zn,Mn, B, Zn and Mn, B, Mn and B when these nutrition ions were absorbed by the apple tree.
