| 摘 要： | 在广东酸性土壤上施用以碱渣为物料生产的活性钙镁肥,水稻获增产、增收,并具改土作用,其肥效和用量受土壤钙镁供给状况及土壤酸度的影响。有效钙镁含量低、酸性强的土壤,钙镁肥作用效果大、增产率高、需肥量较多;反之,较少。

| Abstract: | Rice experiments were conducted for studying active calcium-magnesium fertilizer in acid soil of Guangdong Province. The results showed that the effects of active Ca-Mg fertilizer were obvious on increasing yield and income, and improving soil. Application rate was determined by soil available Ca and Mg content. Crop response of Ca-Mg fertilizer was more significant when soil available Ca and Mg content was low, and soil acidity was serious. |
