A pot experiment was carried out to study effects of mulching with four hyperaccumulator (Solanum photeinocarpum, Tagetes erecta, Galinsoga parviflora and Bidens pilosa) straws on the total phosphorus and total potassium content in all parts of Cyphomandra betacea seedlings under cadmium stress. The results showed that different hyperaccumulator straw had different effects on nutrients uptake of C. betacea seedlings. Compared with the uncovered, mulching with G. parviflora straw not only

Therefore, mulching with G. parviflora straw could significantly promote the nutrients uptake of C. betacea seedlings and provide references for improving nutrients absorption of fruit trees in cadmium contaminated soil.
