摘要

To study the effects of cutting after grafted on nutrient uptake of wild vegetables, four rootstocks (Brassicapekinensis, Brassica napus, Raphanus sativus and Rorippa dubia) were used to graft Nasturtium officinale, and then cutting the seedlings of scions and planted in selenium (Se) contaminated soil. The nitrogen (N), phosphorus (P) and potassium (K) uptakes of N. officinale were investigated by the pot experiment. The rootstocks of B. pekinensis, B. napus, R. sativus, and R. dubia improved the N uptake ability of N. officinale in Se-contaminated soil, but reduce K uptake ability of that. The rootstocks of B. pekinensis, B. napus, and R. sativus increased the P contents in shoots of N. officinale, and the rootstock of R. dubia had on significant effects on that. Therefore, the rootstocks of B. pekinensis, B. napus, R. sativus, and R. dubia could significantly affect the N, P, and K uptake of N. officinale cutting seedlings after grafted, and the best rootstock was R. sativus in Se-contaminated soil.

Officinale的氮（N），磷（P）和钾（K）上升。 B.Pekinensis，B. Napus，R. Sativus和R. Dubia的砧木改善了N. Officinale在SE污染的土壤中的N摄取能力，但降低了k吸收能力。 B.Pekinensis，B. Napus和R. Sativus的砧木增加了N. Officinale芽中的P含量，R. Dubia的砧木对此产生了重大影响。因此，B.Pekinensis，B. Napus，R. sativus和R. Dubia的砧木可能会显着影响嫁接后N，P和K的N，P和K摄取N. Officinale切割幼苗，最好的砧木是R. Sativus硒污染土壤。
