摘要
在萨拉斯阿南农业大学研究站进行了2018年收获季生物氮磷钾联合施用对水稻生长、产量和养分吸收的影响。试验采用随机区组设计，共设12组不同水平铁(Fe)和锌(Zn)处理组合，加或不加生物氮磷钾联合体(Azotobacter sp.、Azospirillim sp.和Bacillus sp.)， 3个重复。Thasra试验田土壤为粘壤土质地，有机碳、速效氮、速效磷含量中等，速效钾含量高，速效锌、铁含量中等。结果表明，施用RDF + 75% Zn + 75% Fe + Bio-NPK复合物(T12)显著提高了水稻籽粒和秸秆的产量和氮、磷、硫吸收。施用RDF + 100% Zn + 100% Fe + Bio-NPK (T10)显著提高了秸秆铁含量和籽粒锌含量。施用RDF + 75% Zn + 75% Fe + Bio-NPK (T12)显著提高了水稻籽粒和秸秆对铁和锌的吸收。施用RDF + 100% Zn + 100% Fe + Bio-NPK (T10)时，水稻秸秆对Cu的吸收量最大。不同处理对水稻收获后土壤速效氮、磷、钾、硫、锌、锰、铜含量均无显著影响。RDF + 75% Zn + 75% Fe (T11)处理显著提高水稻收获后土壤有效铁含量(7.10 mg kg-1)。T12 (RDF + 75% Zn + 75% Fe + Bio-NPK联合体)处理土壤中固氮菌、固氮螺旋菌、增磷菌和钾动员菌的数量均高于对照。
Effects of bio-npk consortium on growth, yield and nutrient uptake by rice under clay loam textured soil
Field experiment was conducted to see the effects of bio-NPK consortium on growth, yield and nutrient uptake by rice during kharif season of 2018 at Research Station, Anand Agricultural University, Thasra. The experiment was laid out in a randomized block design, comprising of twelve treatment combinations of different levels of iron (Fe) and zinc (Zn) with or without bio-NPK consortium (Azotobacter sp., Azospirillim sp. and Bacillus sp.) with three replications. The soil of Thasra experimental field was clay loam texture, medium in organic carbon, available nitrogen (N) and phosphorus (P), high in available potassium (K) and medium in available Zn and Fe. Results revealed that application of RDF + 75% Zn + 75% Fe + Bio-NPK consortium (T12) recorded significantly higher yield and uptake of N, P and S by rice grain and straw. The Fe content in straw and Zn content in grain increased significantly with application of RDF + 100% Zn + 100% Fe + Bio-NPK consortium (T10). Significantly higher Fe and Zn uptake by grain and straw of rice was observed with application of RDF + 75% Zn + 75% Fe + Bio-NPK consortium (T12). Maximum Cu uptake by rice straw was recorded with application of RDF + 100% Zn + 100% Fe + Bio-NPK consortium (T10). The available N, P, K, S, Zn, Mn and Cu content in soil after harvest of rice failed to show any significant influence with different treatments. Significantly higher available Fe (7.10 mg kg-1) in soil after harvest of rice was found in treatment with RDF + 75% Zn + 75% Fe (T11). Maximum population of Azotobacter, Azospirillum, phosphate solubilizing bacteria and potassium mobilizing bacteria in soil was found in treatment T12 (RDF + 75% Zn + 75% Fe + Bio-NPK consortium) over control.
