| 摘 要： | 田间试验结果表明,酸性黄红壤上施用白云石粉显著降低了土壤交互性铝含量和提高了土壤pH值,其 降酸作用与白云石粉用量呈正相关。适当施用白云石粉能够极显著提高油菜产量。白云石粉用量在1 600kg/hm2 时,油菜达到最高产量2 518kg/hm2。此外,施用白云石粉改善了土壤的养分状况,提高了油菜植株的养分含量和 养分吸收量。

| Abstract: | The experiment using dolomite for the amelioration of acidic yellow-red soil was conducted.The results indicated that dolomite application reduced soil exchangeable Al and increaed soil pH significantly.The effect of acidity reduction was positively correlated to the amout of dolomite.Proper dolomite application significantly increased rapeseed yield in the acidic yellow-red soil.The highest yield can be obtained when dolomite application was 1 600kg/hm~2.Besides,dolomite application improved soil nutrient condition,raising nutrient content and uptake of rapeseed plants. |
