| description | A soil pollution remediation and soil fertility improvement method based on smash-ridging tillage comprises the steps that (1) deep ditches are dug in the periphery of a cultivated land to form a drainage system, and the requirement for drainage and irrigation is met; (2) smash-ridging tillageof the cultivated land: the first smash-ridging tillage depth is 40 cm or above, the rice field depth is 25 cm or above, green manure is sown every time after smash-ridging tillage is conducted, and smash-ridging tillage is conducted every 2-3 months in combination with green manure returning and dressing; (3) dry and wet alternate moisture management is carried out according to weather conditions such as rainy seasons after each time of smash-ridging tillage, so that harmful substances such as residual heavy metals and pesticides in the soil move downwards to the bottom layer from the upper layer of the plowing layer, full-field water storage is carried out by utilizing rain in the rainy seasons,and the water is quickly |
