The content of alkali-hydrolyzable nitrogen， available potassium， and slow-release potassium in the soil with diferent acid regulation measures also increased to varying degrees.The N P K + L + G M + O M treatment had the best improving effect on rice yields，with increases of 4 . 5 0 % in the yield of early rice and 6 . 1 0 % in the yield of late rice.The NPK+GM treatment had the highest net income of rice planting， which increased by
