长期外源有机物料添加对双季稻产量、土壤肥力及土壤质量的影响
Effects of exogenous organic materials on the yield of double cropping rice,soil fertility and soil quality
摘要
Abstract
To investigates the effects of 13 consecutive years of different organic amendments on the yield of transplanting double-cropping rice,soil nutrient content,soil aggregates,and soil quality,straw and decomposed cow manure were taken as materials.In the field of Jinhua city of Zhejiang Province,three treatments,e.g.,chemical fertilizer alone(NPK),chemical fertilizer combined with straw and a rapid decomposer(RS),and controlled-release Bulk blending(BB)fertilizer combined with cattle manure(CM)were evaluated.The impacts of long-term organic amendments on the yield of double-cropping rice,soil nutrient content and soil quality were analyzed.The results showed that:The average yield of double-cropping rice from high to low was CM＞RS＞NPK.Compared to the NPK treatment,soil pH was significantly increased by 0.40 and 0.09 units under the CM and RS treatments,respectively(P＜0.05).The bulk density was significantly reduced by 13.69％in the CM treatment(P＜0.05).Compared to the NPK treatment,Soil organic matter,organic carbon,total nitrogen,and nitrate nitrogen contents were significantly enhanced under CM and RS treatments,which in descending order was CM,RS and NPK.Furthermore,the contents of alkaline nitrogen,ammonium nitrogen and exchangeable magnesium were significantly increased by 49.59％,66.26％and 106.06％in the CM treatment,respectively(P＜0.05).Soil aggregate stability,as indicated by the geometric mean diameter(GMD)and mean weight diameter(MWD),was also improved under the CM treatment,with the increases of 9.38％and 9.54％,respectively,compared to the NPK treatment.Soil quality index(SQI)was highest in the CM treatment,with a value of 0.71.In summary,the soil fertility and rice yield were significantly improved by applying controlled-release BB fertilizer combined with cattlle manure in the yellow mud field of central Zhejiang.关键词
