摘要: 对豫南砂姜黑土水浇地高、中、低产田的土壤理化性状(耕层深度、犁底层厚度及土壤容重、有机质含量、碱解氮含量、速效磷含量、速效钾含量)进行分析,研究其与作物产量的相关性,明确砂姜黑土水浇地影响作物产量的关键土壤限制因子,为建立砂姜黑土水浇地合理耕层构建技术奠定基础。结果表明,豫南砂姜黑土水浇地耕层深度为7.25~20.00 cm,平均值为13.67 cm;犁底层厚度为4.75~19.50 cm,平均值为10.98 cm;土壤容重为1.16~1.58 g/cm3,平均值为1.45 g/cm3;土壤有机质含量为14.33~23.67 g/kg,平均值为19.81 g/kg;土壤碱解氮含量为58.80~98.02 mg/kg,平均值为76.09 mg/kg;土壤速效磷含量为7.00~26.28 mg/kg,平均值为15.70 mg/kg;土壤速效钾含量为79.59~171.94 mg/kg,平均值为124.47 mg/kg。不同产田土壤养分含量总体表现为高产田>中产田>低产田。作物产量与土壤容重、犁底层厚度呈极显著负相关,与耕层深度、土壤有机质、速效磷和速效钾含量呈极显著或显著正相关。豫南砂姜黑土水浇地限制作物产量的关键土壤因子由大到小依次为耕层深度、犁底层厚度、土壤有机质含量、土壤容重。

Abstract: The physicochemical properties(topsoil depth,plow sole thickness,soil bulk density,organic matter content,available nitrogen content,available phosphorus content,available potassium content)of irrigated high⁃,medium⁃ and low⁃yield lime concretion black soil in southern Henan were analyzed,the correlation between them and crop yield was studied,and the key soil limiting factors affecting crop yield were clarified,to provide a foundation for the establishment of reasonable topsoil construction technology of irrigated lime concretion black soil.The results showed that the topsoil depth of irrigated lime concretion black soil in south Henan was 7.25—20.00 cm,with an average of 13.67 cm;The plow sole thickness was 4.75—19.50 cm,with an average of 10.98 cm;The soil bulk density was 1.16—1.58 g/cm3,and the average soil bulk density was 1.45 g/cm3;The content of soil organic matter was 14.33—23.67 g/kg,and the average content of organic matter was 19.81 g/kg;The content of soil available nitrogen was58.80—98.02 mg/kg,with an average of 76.09 mg/kg;The content of available phosphorus was 7.00—26.28 mg/kg,with an average content of 15.70 mg/kg;The content of soil available potassium was 79.59—171.94 mg/kg,and the average was 124.47 mg/kg.The overall soil nutrient content of different yield fields was high⁃yield field>medium⁃yield field>low⁃yield field. Crop yield was extremely significantly negatively correlated with soil bulk density and plow sole thickness,and extremely significantly or significantly positively correlated with topsoil depth,soil organic matter content,soil available phosphorus content and available potassium content. The order of key soil factors limiting crop yield in the irrigated lime concretion black soil in south Henan was topsoil depth>plow sole thickness>soil organic matter content>soil bulk density.

Key words: Lime concretion black soil, Crop yield, Topsoil, Physicochemical properties, Soil nutrition content
