Abstract:
A heavy metal cadmium deactivator for activating the activity of sulfur-reducing bacteria in rice field soil, and an application thereof. The deactivator is constituted by electron shuttles alone or electron shuttles and electron donors, but cannot be constituted by electron donors alone. The mass ratio of the electron donors to the electron shuttles is (1:3)-(1:8). Also, a heavy metal cadmium deactivating method for activating the activity of microorganisms in rice field soil, such as sulfur-reducing bacteria. By applying the functional deactivator to rice field soil, the activity of microorganisms, such as sulfur-reducing bacteria, can be activated, thereby accelerating the reduction process of sulfur and iron in soil to facilitate the fixation of cadmium; cadmium adsorption and accumulation in rice is reduced to achieve secure production in fields moderately or lightly polluted by cadmium.

Claim (Index 10):
The method of deactivating the heavy metal cadmium for activating the activity of sulfur-reducing bacteria in rice field soil according to  claim 9 , wherein:\n the heavy metal cadmium deactivator is applied as a base fertilizer 5 to 10 days prior to rice transplanting or as an additional fertilizer during rice tillering and rice field sunning, or is applied in both periods; the dosage of the heavy metal cadmium deactivator is 50-300 kg/mu; the heavy metal cadmium deactivator may be applied as a base fertilizer 5 to 10 days prior to rice transplanting according to the following steps: the rice field needs to be raked evenly for the application of the heavy metal cadmium deactivator before rice transplanting; after application of the heavy metal cadmium deactivator, it is necessary for the rice field to be kept flooded more than 3 cm for more than 15 days; the heavy metal cadmium deactivator may be applied as an additional fertilizer during rice tillering and rice field sunning according to the following steps: sprinkling the heavy metal cadmium deactivator around the rice roots instead of on the leaves, and meanwhile not over drying the soil, so as to ensure that the moisture content in soil is greater than 70% of the saturated moisture content; timely irrigation is necessary when the moisture content in soil is insufficient; after the heavy metal cadmium deactivator is applied, the rice field should be irrigated to over 5 cm in flooding within 3 days and kept flooded for more than 5 days.
