Correlation coefficients among rice yield and soil physico-chemical and biological properties.

Only the significant correlations are shown.Abbreviations: BD, bulk density; SOC, soil organic carbon; TN, total N; AN, available N; AP, available P; AK, available K; CEC, cation exchange capacity; ASi, available Si; AZn, available Zn; DH, dehydrogenase; BG, β-glucosidase; ARS, arylsulfatase; ACP, acid phosphatase; POD, peroxidase; G+, gram-positive; G-, gram-negative; TB, total bacteria; ACT, actinomycetes; AMF, arbuscular mycorrhizal fungi.Correlation coefficients among rice yield and soil physico-chemical and biological properties.

仅展示具有统计学显著性的相关关系。缩写说明：BD为容重（bulk density）；SOC为土壤有机碳（soil organic carbon）；TN为全氮（total N）；AN为速效氮（available N）；AP为速效磷（available P）；AK为速效钾（available K）；CEC为阳离子交换量（cation exchange capacity）；ASi为有效硅（available Si）；AZn为有效锌（available Zn）；DH为脱氢酶（dehydrogenase）；BG为β-葡萄糖苷酶（β-glucosidase）；ARS为芳基硫酸酯酶（arylsulfatase）；ACP为酸性磷酸酶（acid phosphatase）；POD为过氧化物酶（peroxidase）；G+为革兰氏阳性菌（gram-positive）；G-为革兰氏阴性菌（gram-negative）；TB为总细菌（total bacteria）；ACT为放线菌（actinomycetes）；AMF为丛枝菌根真菌（arbuscular mycorrhizal fungi）。水稻产量与土壤理化、生物学性状间的相关系数。
