1种稻对滨海盐碱土改良的效果1.1加快土壤脱盐过程种稻前1m土层含盐量为0.533%,经种稻五年降至0.235%,种稻15年降至0.119%,种稻35年降至0.114%。从多年变化规律看,稻田土镇盐分是处于淋溶大于或平衡状态的年循环变化过程。土壤继续向脱盐化方向发展。1.2加速了地
Effect of 1 Rice on Coastal Saline-Alkali Soil Improvement 1.1 Speeding up soil desalination The salinity of 1m soil layer before planting rice was 0.533% 0.119%, rice dropped to 0.114% 35 years. From the perspective of years of change, salt content in the paddy soil is in the process of leaching over or over the annual cycle. The soil continues to develop in the direction of desalination. 1.2 accelerated to the ground
