鸡粪和猪粪对小麦生长及土壤重金属累积的影响
Effects of Application of Chicken Manure and Pig Manure on the Growth of Wheat and Heavy Metal Accumulation in Soil
摘要
Abstract
Excessive application of organic manure could result in potential threat to environment.The pot ex-periment was carried out to study the effects of the application of chicken manure and pig manure to soils with rela-tively high heavy metal content on the growth of wheat and the accumulation of heavy metal in soil.The results showed that with the increasing of chicken manure,soil Cu,Zn,Cr,Pb,Cd increased obviously.With the increasing of the amount of pig manure,soil Cu,Zn,Cd increased obviously.The soil heavy metals contents of all the treatment did not exceed the Chinese Soil Environmental Quality Standard Ⅱ(GB15618-1995).Compared with the treatment of chemical fertilizer,chicken manure of 60,90 t/ha significantly increased soil Cu content,was 16.70% and 18.61%,respectively.The soil Zn,Cr content for the treatment of chicken manure (15 -150 t/ha) increased sig-nificantly,varied from 33.86% -326.45% and 9.43% -31.65%,respectively.For the treatments of chicken ma-nure of 90,150 t/ha,soil Pb and Cd content increased significantly.The soil Pb content increased 19.41% and 22.91%,respectively.The soil Cd content increased 30.83% and 50.49%,respectively.The soil Cu and Zn for 45 -150 t/ha pig manure treatments increased,varied from 19.67% -61.53% and 7.78% -32.68%,significantly. Pig manure of 150 t /ha significantly increased the soil Cd content,was 50.43%.The heavy metal contents in wheat grain sample of all the fertilization application treatment were lower than the National Food Hygiene Standards (GB2762-2012).关键词
