Abstract:
Taking pakchoi and radish as material,the effects of reclaimed water irrigation and sludge fertilization on the seed germination rate and seedling growth of pakchoi and radish were analyzed.The results showed that the reclaimed water irrigation favored both germination of pakchoi seeds,growth of pakchoi underground part and increase of fresh weight.The biomass of pakchoi irrigated with reclaimed water+sludge fertilizer increased by 55.70% compared to the pakchoi only treated with clean water.Sludge fertilizer favored seeds germination and growth of radish.The biomass of radish irrigated with reclaimed water+sludge fertilizer increased by 52.98% compared to the radish only treated with clean water.The latter one had the shortest root length and the minimum weight.The total chlorophyll content of pakchoi irrigated with clean water was the highest,while the MDA content was the lowest.There was negative correlation between total chlorophyll content and MDA content of pakchoi (r=-0.7048),while there was no significant correlation between them in radish leaves.The chlorophyll content of radish irrigated with clean water was the highest,while the MDA content of radish irrigated with reclaimed water and fertilized with sludge was the highest.
