红壤是一种棕红色或红棕色的土壤,广泛分布在我国南方山区或丘陵地区。由于高温多雨的气候,使土壤中有机质和矿物质迅速分解,并使分解出的盐分与养分溶解在雨水中沿着坡面淋失。因此,冲刷严重的瘦红壤都存在酸性大,养分不足和结构不良等缺点。 Red soil is a reddish brown or reddish brown soil, widely distributed in mountainous areas in southern China or hilly areas. Due to the hot and rainy climate, organic matter and minerals in the soil are rapidly decomposed and the dissolved salts and nutrients are dissolved in rainwater to lean along the slope. Therefore, scouring the thin red soil are acidic, nutrient deficiencies and poor structure and other shortcomings.
