摘要:

本研究以根际土壤为研究对象,设置菜心-玉米轮作与非轮作处理,分析土壤有机质含量、土壤有效磷含量、土壤微生物生物量磷(SMBP)含量、土壤酸性磷酸酶活性和土壤微生物生物量碳(SMBC)含量在轮作周期内的变化,并采用Pearson法分析各指标间的相关性。结果表明,菜心-玉米轮作处理的根际土壤有机质含量、有效磷含量、SMBP含量与酸性磷酸酶活性在作物种植期均显著(p<0.05)高于非轮作处理,SMBC/SMBP均低于非轮作处理,比值在30以下。土壤有效磷含量与SMBP含量、土壤酸性磷酸酶活性、土壤SMBC含量和土壤有机质含量之间呈极显著(p<0.01)正相关,相关系数分别达0.869、0.815、0.611与0.441,与SMBC/SMBP和土壤pH值呈显著负相关关系,相关系数分别达-0.397与-0.850。轮作显著激活土壤磷素循环,促进作物对土壤中磷素的利用,实现养分的平衡吸收,兼顾农业生产与土壤培育。

Abstract:

This study took rhizosphere soil as the research object, and set up Brassica campestris var. parachinensis rotation and non-rotation treatments to analyze the changes in soil organic matter content, soil available phosphorus content, soil microbial biomass phosphorus (SMBP) content, soil acid phosphatase activity, and soil microbial biomass carbon (SMBC) content during the rotation cycle. Pearson method was used to analyze the correlation between each indicator. The results showed that the organic matter content, available phosphorus content, SMBP content, and acid phosphatase activity in rhizosphere soil of the Brassica campestris var. parachinensis-maize rotation treatment were significantly (p<0.05) higher than those of the non-rotation treatment during the crop planting period, while the SMBC/SMBP ratio was lower than that of the non-rotation treatment, with a ratio below 30. Soil available phosphorus content was extremely significantly (p<0.01) positively correlated with SMBP content, soil acid phosphatase activity, SMBC content, and soil organic matter content with correlation coefficients of 0.869, 0.815, 0.611, and 0.441, respectively. However, it was significantly negatively correlated with SMBC/SMBP ratio and soil pH value, with correlation coefficients of -0.397 and -0.850, respectively. Rotation significantly activated soil phosphorus cycling, promoted crop utilization of phosphorus in the soil, achieved balanced-nutrient absorption, and balanced agricultural production and soil cultivation.

Key words: rotation, soil phosphorus, soil available phosphorus, soil microbial biomass phosphorus, acid phosphatase
