Example Embodiment
[0013] Example 1: A phytocombination method for remediation of heavily cadmium-contaminated paddy soil. The specific embodiment is as follows: (1) the combination of plants for restoration is: reeds, lotus seed grass, water bamboo shoots, barnyardgrass, duck tongue, and willow sage; (2) the planting method is: different types, different heights (3) Plant harvest period and harvest method: 50 days after plant planting, when the amount of absorbed and extracted Cd reaches a saturated state (see appendix figure 2 ) is harvested in one go, the whole plant is uprooted and then processed centrally. After the plants are harvested, the soil is leveled, and the next round of phytoremediation can be performed as needed; (4) Water management of paddy fields: before restoration, the paddy fields are irrigated to a thin water layer (about 3 cm), and then plants are planted. Drain the standing water after the plants are alive, and let the soil dry naturally until it is slightly dehydrated...
