- 摘要:
- 以辣椒为研究对象,以5种微生物菌剂为试验材料,开展不同微生物菌剂对辣椒土壤改良效果,筛选出能够缓解辣椒连作障碍及合适的微生物菌剂,以期得到当地最优的微生物菌剂,为宁南连作辣椒改良技术集成提供参考依据。结果表明:施加微生物菌剂处理影响各生育期连作辣椒土壤碱性磷酸酶的活性,土壤碱性磷酸酶活性随生育期的延长呈现先升高后略有下降的趋势;微生物菌剂处理下土壤速效钾含量随各生育期变化不大,但显著影响开花期和成熟期土壤有机质含量;不同微生物菌剂处理对不同生育期的土壤全磷含量影响程度不同。综上所述,施加微生物菌剂均对缓解辣椒连作障碍表现出积极的正向作用。
- Abstract:
- Taking peppers as the research object and five microbial agents as experimental materials,the effects of different microbial agents on improvement for the soil of peppers were studied to screen for suitable microbial agents that can alleviate the obstacles of continuous cropping of peppers,in order to obtain the optimal microbial agent in the local area and provide reference for the integration of continuous cropping peppers improvement technology in Ningnan.The results showed that the application of microbial agents affected the activity of alkaline phosphatase in the soil of continuous cropping peppers at different growth stages,the activity of soil alkaline phosphatase showed a trend of first increased and then slightly decreased with the extension of growth period;the content of available potassium in soil under microbial agent treatment didn′t significantly change with different growth stages,but it significantly affected the soil organic matter content during the flowering and maturity stages;the impact of different microbial agents on the total phosphorus content of soil at different growth stages varied.In summary,the application of microbial agents had a positive effect on alleviating continuous cropping obstacles in peppers.
