| 摘 要： | 为探寻比磷石膏更好的黄壤耕地调理剂,采用田间小区试验的方法,在黔西县进行了不同调理剂改良黄泥土的效应试验.结果表明:沸石、磷石膏、粉煤灰在垄作、规范化种植的基础上玉米增产效果明显,粗蛋白含量明显提高,土壤有机质、全量氮、磷、钾比对照土壤略有增加,土壤pH、有效磷略有增加.综合考虑认为,粉煤灰的改良效果与磷石膏相当,沸石是比磷石膏更好的土壤调理剂.

| Abstract: | The plot test was conducted to investigate effects of different ameliorants on yellow soil for replacing the phos-gypsum in Qianxi county. The results showed that the maize yield and crude protein content were significantly increased by using zeolite, phos-gypsum and coal ash under the ridge and standard cultivation, the pH and organic matter, total N,total P, total K and available P contents of the tested soil were slightly more than those of CK, the improvement effect of applying coal ash was about equal to phos-gypsum and the zeolite was the better soil ameliorant compared with phos-gypsum. |
