摘　　要：以绿橙园土壤和绿橙苗为材料,施用不同改良剂进行盆栽改良试验。结果表明,施用有机肥和改良剂对绿橙园土壤的酸碱度、有效养分及土壤结构都有着积极的改进作用,还可以促进绿橙苗的生长。通过各处理间的对比试验,发现各处理以有机肥(2‰)+熟石灰(1‰)和有机肥(2‰)+钙镁磷肥(1‰)效果最优。土壤pH分别较对照提高了1.23和0.82,土壤交换性铝含量分别减少了97.65%和96.86%;二者土壤团粒结构占比增加1.52%以上;绿橙苗地上部分干重高于对照40.09%以上。Green orange garden soil and green orange seedling were used as materials,and different soil modifiers were used to carry out pot experiment.The results showed that the application of organic fertilizer and soil modifiers could improve the pH,available nu⁃trients and soil structure of green orange garden soil.It can also promote the growth of green orange seedlings.Through the contrast test among the treatments,it was found that the effect of organic fertilizer(2‰)+hydrated lime(1‰)and organic fertilizer(2‰)+cal⁃cium magnesium phosphate(1‰)were the best.Compared with the control,the pH of soil increased by 1.23 and 0.82,the exchange⁃able aluminum content of soil decreased by 97.65%and 96.86%,respectively,the percentage of soil aggregate structure increased by more than 1.52%,and the dry weight of aboveground part of green orange seedling was higher than that of the control by more than 40.09%.
