| 摘 要： | 在低pH的酸性红壤、近中性的黄棕壤和高pH的盐土中加入茶叶、稻草、大豆3种植物茎叶碎末进行室内培养，研究不同植物材料在短期腐解过程中对不同土壤pH的影响。结果表明：经过14d培养后，茶叶轻微降低红壤和盐土的pH，对黄棕壤的pH没有影响；稻草亦显示出类似的趋势；大豆叶可使酸性红壤和中性黄棕壤的pH有一定程度升高，但使盐土的pH有所下降。

| Abstract: | By mixing tea powder, rice straw powder and soybean leaf powder into low-pH red soil, near-neutral-pH yellow brown soil and high-pH salt soil, the changes of soil pH were explored. After 14 d incubation with tea powder and rice straw powder red soil and salt soil showed a slight decrease in the pH value, while yellow brown soil remained the original pH value. On the contrary, after incubation with soybean leaf powder the pH value of red soil and yellow brown soil significantly increased, while the pH value of salt soil reduced. |
