Abstract

A pot experiments were conducted to study the effect of mulching tolerance plant straw on phosphorus and potassium uptakes of Cyphomandra betacea seedlings under cadmium (Cd) stress, four tolerance plants (Digitaria sanguinalis, Clinopodium confine, Plantago asiatica, Ranunculus sieboldii) straw were used as materials to mulch on the surface of Cd-contaminated soil and planted C. betacea seedlings. Cd-contaminated soil-mulched tolerant plant straw had effect on the contents of phosphorus and potassium in C. betacea seedling plants. Except for the P. asiatica straw mulching treatment, the contents in phosphorus and potassium in the roots of C. betacea seedlings treated with D. sanguinalis straw, R. sieboldii, and C. confine straw were significantly higher than those without soil-resistant straw. The contents of phosphorus and potassium in shoots of C. betacea seedlings were higher than those of control after mulching four tolerant plant straw, indicating that mulching tolerant plant straw promoted the translocation of phosphorus and potassium to the shoots of C. betacea seedlings. This experiment showed that compared with the P. asiatica straw, the straw mulched with D. sanguinalis straw, the C. confine straw, and the R. sieboldii straw were more beneficial to the uptake of tolerant in Cd-contaminated soil by C. betacea seedlings.
