用盆栽试验研究了施用锰肥和锌肥对京郊缺锰潮土(DTPA-Mn3.54ppm,DTPA-Zn0.55ppm) 上生长的冬小麦体内锰元素的积累与分布模式的影响,结果表明,冬小麦对锰有两次吸收高峰,分别在冬前期和开花期;施锰增加了植株对锰的吸收,施锌则对锰锰的吸收、转移和再分配产生拮抗作用。随生长期时间的推移,地上部锰的浓度呈“N”字型变化,锰的浓度分布模式相对稳定,不受施肥处理的影响。
Pot experiments were conducted to study the effects of manganese and zinc fertilizers on the accumulation and distribution pattern of manganese in winter wheat grown on the Mn-deficient terrain (DTPA-Mn3.54ppm, DTPA-Zn0.55ppm) in the suburbs of Beijing. The results showed that winter wheat Manganese had two peak absorption, respectively, in the winter pre-flowering and flowering; application of manganese increased the absorption of manganese plants, while the application of manganese on Mn and Mn absorption, transfer and redistribution of antagonism. With the growth period of time, the aboveground manganese concentration showed “N” shape change, manganese concentration distribution pattern is relatively stable, not affected by fertilization treatment.
