The invention belongs to the technical field of rice production, and discloses a rice production method for lowering heavy
metal cadmium pollution. The rice production method for lowering heavy metalcadmium
pollution comprises the steps: after autumn harvest, stubble is left in a
paddy field,
plant ash is scattered for covering, plowing treatment is conducted after 3-7 days, and heavy
metal polluted water is prevented from entering the
paddy field; early-mature rice varieties with high
disease resistance are selected to be pretreated, and seeds are soaked, disinfected through
trichloroisocyanuric acid, and then subjected to pregermination and
seedling culture for standby application; about 15 days before
transplanting of rice seedlings, water treated through caustic soda or
lime and
polyaluminum chloride conducts field
steeping, and arabis gemmifera is planted on the two sides of ridges; and after field
steeping is completed, the
paddy field is ploughed, special
fertilizer is applied,then the rice seedlings are transplanted, and regular drainage, water replenishing and fertilization are conducted. The adopted method is simple and good in effect, the
cadmium treatment cost is lowered, the
economic benefits of farmers are increased, the rice yield is increased, and
food safety is ensured.
