Abstract
[Objective] The aim of the study was to seek whether municipal sludge organic fertilizer could be used in spinach.[Method]The influence of sewage sludge compost application on spinach growth and soil environment were studied,a greenhouse,soil column tester experiment was conducted with different levels of sludge compost,organic fertilizer source was sewage sludge compost which obtained from the Panggezhuang sludge composting plant in Beijing.A two factor gradient test design with four treatments(rates of sludge application expressed as sludge to soil area)of 0(control),2,4,and 6 kg/m2 and two soil types(loam soil and sand soil)with 3 replications was established to test spinach plant height,diameter,leaf area,heavy metals of spinach and soil nutrient and organic matter and soil heavy metals.[Result]The application of sewage sludge compost showed that,on the growth promoting effect of spinach,4 kg/m2 sludge treatment was better than the others.Compared with no sewage sludge application,sludge treatment had promoted growth of spinach,increased nutrient and organic matter in soil,sewage sludge compost had been a significant correlation with the content of heavy metals in sludge.[Conclusion]Municipal sludge organic fertilizer could be used in spinach,the amount of imposed appropriate was 4 kg/m2.
