摘    要:白云石改良酸性黄红壤三年定位试验结果表明:酸性黄红壤施用白云石可以降低土壤交换性铝的含量,提高土壤pH值和交换性钙、镁的含量,显著提高作物产量,且有明显的后效。第1—6季作物分别增产10.8%~13.4%、21.5%~48.6%、9.4%~16.2%、10.9%~44.6%、7.9%~22.0%和6.6%~29.8%。白云石施用量为600kg hm-2时,降酸作用可维持3季作物以上;白云石施用量为2500 kg hm-2时,降酸作用可维持6季作物以上。

关 键 词:白云石  酸性黄红壤  产量  化学性质

Abstract:The results of the three-year field location experiment showed that the application of dolomite could increase soil pH,decrease soil exchangeable Al content,and increase exchangeable Ca,Mg contents and crop yield significantly.The 1-6 season crops yield increased by 10.8%-13.4%,21.5%-48.6%,9.4%-16.2%,10.9%-44.6%,7.9%-22.0% and 6.6%-29.8%,respectively.The results also showed that the application of dolomite had residual effect which depended on its application rates.When the amount of dolomite application was 600kg ha~(-1),the effect of reducing soil acidity could last for 3 seasons,while it was 2500 kg hm~(-2),the effect could last over 6 seasons.
Keywords:Dolomite  Acid red-yellow soil  Yield  Chemical properties
