| 摘 要： | 长达１５年的田间石灰长期定位试验结果显示：红壤施用３．７５～１５．００ｔ／ｈｍ２石灰石粉降低土壤酸度的后效可以维持４～１５年，使油菜增产和肥料利用率提高所维持的时间则可达１５年以上。红壤施用石灰可以提高油菜籽粒产量１７．５％～２９．８％，提高Ｎ、Ｐ和Ｋ肥料利用率的幅度分别为１７．６％～３３．０％，２５．６％～３９．７％和６．８％～３６．１％。

| Abstract: | The results of a 10year long term lime experiment shown that the residue effect of reducing soil acidity of red soil by liming 3.7515.00 t ground limestone/hm2 could last 415 years. However, the increased rapeseed yield and fertilizer utilization efficiency (FUE) by liming could last more than 15 years. Liming increased grain yield of rapeseed by 17.5).8%, and increased the ranges of FUE for N, P, and K by 17.63.0%, 25.69.7%, and 6.86.1%, respectively. |
