摘要
为探究连续13年不同有机物料添加对双季稻产量、土壤养分含量、团聚体及土壤质量的影响,在浙江省金华市水稻田,采用育秧移栽种植模式,设置单施化肥(NPK)、化肥配施秸秆添加快腐熟剂(RS)和控释掺混肥(BB)配施腐熟牛粪(CM)3个施肥处理,分析了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。结果表明:各处理双季稻产量由高到低均表现为CM>RS>NPK;与NPK相比,CM和RS的土壤pH分别升高0.40和0.09(P<0.05),CM的土壤容重降低13.69%(P<0.05),CM和RS的土壤有机质、有机碳、全氮和硝态氮含量的差异均达到显著水平,由高到低均表现为CM>RS>NPK;CM的碱解氮、铵态氮和交换性镁含量显著高于NPK(P<0.05),分别较NPK升高49.59%、66.26%和106.06%,CM的土壤团聚体几何平均直径(GMD)和平均重量直径(MWD)分别为1.05和1.90,分别较NPK升高9.38%和9.54%,CM的土壤质量指数(SQI)最高,为0.71。综上,控释BB肥配施腐熟牛粪可显著提升浙中黄泥田土壤肥力和水稻产量。
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 doublecropping 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.
