The invention provides a method for reducing cadmium accumulation in cyphomandra befacea through mixed planting of galinsoga parviflora grafting offspring, and belongs to the technical field of plantheavy metal pollution repairing. The method is characterized by firstly grafting herba bidentis bipinnatae, serving as a stock with the galinsoga parviflora, serving as a scion, and then carrying outthe mixed planting on galinsoga parviflora grating offspring and the cyphomandra befacea, wherein a mixed planting ratio is 1 to 3. According to the method provided by the invention, the cadmium content in the cyphomandra befacea can be remarkably reduced, and the biomass of all parts of the cyphomandra befacea is remarkably increased; compared with the mixed planting of other hyperaccumulators, more efficient cadmium repairing capacity is expressed, and a best production effect can be achieved.

The invention provides a hybridizing method for grafted progeny of solanum americanum and soybeans to reduced cadmium accumulation in the soybeans and belongs to the technical field of heavy metal pollution repair of plants for hybridization. According to the hybridizing method, the grafted progeny of solanum americanum and the soybeans are adopted for hybridization, and the grafted progeny of solanum americanum are the progeny obtained by grafting tomatoes as rootstocks on solanum americanum. By using different heteroplastic grafted progeny of solanum americanum and the soybeans for hybridization and using a single type of soybeans and mixed ungrafted progeny of solanum americanum as contrasts, the influence of the different heteroplastic grafted progeny of solanum americanum on cadmium accumulation in the soybeans is researched under a condition of cadmium stress, and results show that when the grafted progeny of solanum americanum which are obtained by scion grafting of the tomato rootstocks and solanum americanum are adopted for being hybridized with the soybeans, the biomass of various parts of the soybeans can be significantly increased, and the cadmium content in the soybeans is effectively decreased. Compared with other heteroplastic grafted progeny of solanum americanum, the grafted progeny of solanum americanum have a more efficient cadmium repairing capability.

The invention provides a method for reducing cadmium accumulation in grapes through mixed planting of cosmos sulphureus grafting offspring, and belongs to the technical field of plant heavy metal pollution repairing for the mixed planting. The method for the mixed planting is characterized in that different cosmos sulphureus plant grating offspring in different sizes is adopted for carrying out the mixed planting with the grapes, and the different cosmos sulphureus plant grating offspring in different sizes is the offspring which is obtained by mutually grafting two cosmos sulphureus plants indifferent sizes. According to the method provided by the invention, different cosmos sulphureus grating offspring is adopted for carrying out the mixed planting with the grapes, the influence of different cosmos sulphureus grating offspring on the cadmium accumulation in the grapes under a cadmium stress condition is researched, a result shows that when different cosmos sulphureus plant graftingoffspring in different sizes is adopted for carrying out the mixed planting with the grapes, the cadmium contents of all parts of the grapes can be remarkably reduced, and meanwhile, the accumulationamount of cadmium in a hyperaccumulator-cosmos sulphureus can be effectively increased; compared with other cosmos sulphureus grafting offspring, more efficient cadmium repairing capacity is expressed, and a very good agricultural production effect can be achieved.

The invention discloses a chrysanthemum renovation method for soil polluted by heavy metal Cd. The method is characterized by comprising the following steps of (1) optimal selection of a chrysanthemumvariety; (2) field experiments of the selected chrysanthemum variety; (3) sample collection and analysis test; (4) evaluation of the renovation effect; (5) evaluation of the economic benefit. According to the method, a conditioner for promoting the absorption of heavy metal elements in rhizospheres is compounded, the renovation efficiency is improved, and the economic benefit is increased while the polluted soil is quickly renovated.

The invention provides a method of mixed planting of grafted progeny of Solanum photeinocarpum Nakamura et odashima for increasing cadmium accumulation of the Solanum photeinocarpum Nakamura et odashima, and belongs to the technical field of application of hyperaccumulators to remediation of heavy metal pollution of soil. According to the mixed planting method, the grafted progeny of the Solanum photeinocarpum Nakamura et odashima obtained from wild potato rootstock and the Solanum photeinocarpum Nakamura et odashima by scion grafting is subjected to mixed planting with non-grafted Solanum photeinocarpum Nakamura et odashima. Different grafted progeny of the Solanum photeinocarpum Nakamura et odashima is selected for mixed planting with the non-grafted Solanum photeinocarpum Nakamura et odashima, the influence of the different grafted progeny of the Solanum photeinocarpum Nakamura et odashima subjected to mixed planting on cadmium accumulation under the condition of cadmium stress is researched, results prove that the effects on the cadmium accumulation characteristic of the Solanum photeinocarpum Nakamura et odashima are completely different by mixed planting of the different grafted progeny of Solanum photeinocarpum Nakamura et odashima, when the grafted progeny of the Solanum photeinocarpum Nakamura et odashima obtained by grafting of the mild potato taken as rootstock and the Solanum photeinocarpum Nakamura et odashima as scion is subjected to mixed planting with the non-grafted Solanum photeinocarpum Nakamura et odashima, cadmium accumulation of the Solanum photeinocarpum Nakamura et odashima can be increased to the greatest extent, and efficient cadmium repair capacity is shown.
