本文选用具有代表性两种母质发育的褐土进行盆栽试验。结果表明，红土母质褐土施钾在拔节期谷子对Ｎ、Ｐ、Ｋ、Ｃａ、Ｍｇ、Ｆｅ、Ｍｎ、Ｃｕ和Ｚｎ的吸收均有促进作用，而在黄土母质褐土上谷子对Ｃａ、Ｍｇ和Ｍｎ的吸收都随施钾量增加而下降。施钾对谷子苗期生长发育有明显的促进作用，有助于谷子穗分化，增加千粒重，加速光合产物的运输，提高谷子产量。
In this paper, the representative of the two parent material development of cinnamon pot experiments. The results showed that potassium fertilization in red soil parental cinnamon promoted the uptake of N, P, K, Ca, Mg, Fe, Mn, Cu and Zn at the jointing stage. However, And Mn absorption decreased with the increase of potassium supply. Application of potassium on the growth and development of millet significantly promote the role of cereal spike contribute to differentiation, increase 1000-grain weight, speed up the transport of photosynthetic products and improve the yield of millet.
