| 摘 要： | 采用田间试验方法,在土壤中施用不同水平组合的磷、锌肥,在小麦的不同生育时期(苗期、拔节期、抽穗期、灌浆期以及成熟期)分器官对磷-锌营养关系进行了研究.结果表明,施磷降低了小麦地上部各器官锌含量,且水平越高效果愈明显,在作用时间上主要表现在生长前期(苗期、拔节期和抽穗期)；小麦苗期、拔节期和成熟期地上部各器官磷含量在施锌...

| Abstract: | A field experiment using 4 genotypes of winter wheat(Zhongyu6,Xianyan22,Xiza1,Zhengmai9023)which have different zinc efficiency was conducted to investigate the interaction of P-Zn of wheat plants under different combinations of Zn and P fertilization rates.Zinc rates were supplied at two levels of deficient(0 kg/ha)and normal(7 kg/ha),and P was designed in five rates,namely,0(deficiency),50(low),100(normal),150(high),200(excess)kg/ha.The obtained results showed that P application to soil led to shoot zinc ... |
