| 摘 要： | 在酸性硫酸盐土壤未垦和已垦地上进行的磷矿粉田间试验结果表明，未垦地上直接施用磷矿粉对水稻有显著的增产作用，主要表现在促进水稻株高、分蘖数、穗数的增加上．但在已垦地上磷矿粉对水稻的增产作用不甚明显．施肥后对相关的土壤肥力状况变化也进行了报道．

Effect of Rock Phosphates From Different Sources on Rice Grown on Acidic Sulphate
Soils |
| |
| Abstract: | Effects of six types of phosphates(1 Calcine rock phosphate from Morocco, 2 Brut rock phosphate from Morocco, 3 Rock phosphate from Algeria, 4 Kunyang rock phosphate from Yunnan of China, 5 Single superphosphate（SSP）from Yunnan of China, and 6 Triple superphosphate(TSP）from Yunnan of China）on rice grown on both cultivated and uncultivated acid sulphate soils were studied in 1998. On uncultivated soils, all phosphates increased significantly the plant height, tiller numbers, panicle number and grain yield of the rice. Two available phosphates（SSP and TSP） increased the grain yield more significantly than all other rock phosphates. On cultivated soils, no significant difference in rice yields was recorded. |
