【 摘 要 】

In order to study the effects of treated wastewater combined with manure and chemical fertilizers on the nutrients content and forage yield in corn, field experiments were conducted in 2007. The experiments were conducted in a split plot design with three replications. The treatments were comprised of two levels of irrigation water (W1= well water and W2= wastewater) in the main plot and five levels of fertilizer (F1= unfertilized, F2 = 100% manure, F3= 50% manure, F4= 100% fertilizer, and F5= 50% fertilizer) in the subplot. Results showed that, compared to ordinary water, irrigation with treated wastewater significantly increased fresh and dry forage yield of corn. The treatment using treated wastewater also had a significant effect on N, P, and K contents in corn forage. However, wastewater had no significant effect on plant Fe, Mn, and Zn contents. Among the fertilizer treatments, the highest fresh and dry forage yields and the highest N, P and K contents belonged to the treatments using 100% fertilizer. The highest Fe, Mn, and Zn contents were observed in plants in the treatment with 100% manure.
