Abstract:
Taking rape as material,to evaluate the security of sludge organic fertilizer,effects of different application rates of sludge organic fertilizer (0,50,100,200,400 g/pot) on yield and content of heavy mental in soil and rape were studied.The results showed that the yield increased with the application rates.but the yield didn’t increased when the application rats was above 200 g/pot.The Cu,Zn contents of soil and plant of 400 g/pot were the highest,but there was no difference among the other treatments.The heavy mental contents of soil and plants were within the security standard of agricultural products and soil quality.
