Effects of Mushroom Residue Application on Soil Microorganisms, Soil Fertility,Yield of Summer Maize(Zea mays L.)
摘要
Abstract
A field experiment was conducted to study the effects of mushroom residue on soil microorganisms,soil fertility and maize yields.This study designed 4 application levels of 0(CK),10 000(LM),15 000(MM) and 20 000 kg(HM) mushroom residue per hectare.The results showed that the quantity of bacteria,actinomycetes,fungi in the HM,MM,LM treatments increased by 68.0％-133.3％ (P＜0.01),60.0％-95.2％ (P＜0.01),29.4％-47.1％ compared to the CK,respectively.Soil organic matter,active organic matter,available N,available P and available K in the HM,MM,LM treatments were 14.7％-25.0％ (P＜0.05),35.3％-47.1％ (P＜0.01),9.7％-13.8％(P＜0.05),17.6％-25.6％(P＜0.01),9.6％-15.7％ higher than the CK,respectively.The ratio of active organic matter to total organic matter increased from 14.7％ to 17.2％-17.6％.The maize yields in the HM,MM and LM treatments increased by 9.62％,9.18 ％,7.07％ (P＜0.05) compared with the CK.The results showed that mushroom residue application could significantly improve the soil microorganisms,nutrient contents and the yield of summer maize.关键词
