摘要：以南阳麦饭石为土壤改良剂,利用恒温土培实验系统地研究麦饭石用量对湖南攸县典型酸性土壤的p H值和阳离子交换性能的影响。研究结果表明:麦饭石可以有效提高供试土壤的p H值,恒温培养时间越长,供试土壤的p H值提高幅度越大;施用麦饭石可显著提高土壤的盐基饱和度,24 h培养时间内,盐基饱和度增大的速率最快;麦饭石还可以有效降低土壤的交换性酸和石灰需要量。
The pH and cation exchange of typical acidic soil which from You county of Hunan province were studied by taking Nanyang medical stone as soil conditioner, using constant temperature soil culture experiment systemically. The results showed that with the increase of medical stone dosage, the pH of experimental soil increased gradually, the longer the test, the faster the rate of pH increased. The degree of base saturation of soil was improved significantly by using medical stone, in 24 h, the rate of the degree of base saturation increased fastest. Adding medical stone to soil can reduce the amount of exchangeable acidity and lime requirement in the soil effectively.
