土壤酸碱性是土壤的一个重要特性,也是影响土壤肥力的一个重要因素。它一方面引起土壤一些性质的变化;另方面直接影响作物的生长。一般作物在中性、弱酸性、弱碱性土壤中生长最适宜,过酸过碱都会影响作物的生长。因此,我们必须了解土壤的酸碱性 Soil acid-base is an important feature of the soil, but also an important factor affecting soil fertility. On the one hand, it causes some changes of soil properties; on the other hand, it directly affects the growth of crops. General crops in neutral, weakly acidic, weakly alkaline soil growth is the most appropriate, over-acid over-alkali will affect the crop growth. Therefore, we must understand the pH of the soil
