Abstract

A pot experiment was carried out to study the effects of intercropping on zinc (Zn) uptake of maize and sweet potato seedlings. Intercropping with sweet potato increased the root biomass of maize seedlings, but reduced the stem, leaf and shoot biomasses of maize seedlings. Intercropping with maize increased the root, stem, leaf and shoot biomasses of sweet potato seedlings. Intercropping decreased the chlorophyll and carotenoid contents in maize seedlings, but increased that in sweet potato seedlings. Intercropping decreased Zn content in roots of maize seedlings, and increased Zn contents in stems, leaves and shoots of maize seedlings, which increased by 7.32% of shoots compared with the monoculture. For sweet potato, Intercropping increased Zn contents in roots, stems, leaves and shoots of maize seedlings, which increased by 30.76% of shoots compared with the monoculture. Therefore, intercropping could inhibit the growth of maize seedlings and promote the growth of sweet potato seedlings, and improve Zn uptake of two crops.
