摘要:

本研究探究了设施大棚内施用不同用量氟啶胺对土壤微生物环境和小白菜生长的影响。结果表明:氟啶胺对设施土壤微生物有较好的抑菌效果,尤其对土壤放线菌和真菌的抑制效果更为明显,土壤微生物总量与氟啶胺用量呈负相关关系;施用氟啶胺降低了土壤脲酶、蛋白酶和脱氢酶的活性,增强了土壤磷酸酶的活性。此外,施用6.0 L·hm-2氟啶胺对小白菜根肿病的防控效果最好,3.0和4.5 L·hm-2处理次之;而随着氟啶胺用量的增加,小白菜的生物产量呈现先增加后降低的趋势,其中以1.5 L·hm-2氟啶胺处理后的产量最高,较对照增加22.2%。综上,在大棚蔬菜生产中氟啶胺的合理用量为1.5~3.0 L·hm-2

Abstract:

This study investigated the effects of different fluridine application rates in greenhouse facilities on soil microbial environment and Chinese cabbage growth. Results demonstrated that fluridine exhibited antibacterial effects on soil microorganisms,particularly pronounced against actinomycetes and fungi,with a clear negative correlation between total soil microbial biomass and fluridine application rates. Fluridine application reduced the activity of soil urease,protease,and dehydrogenase,while enhancing phosphatase activity. Notably,a fluridine rate of 6.0 L·hm-2 showed the most effective control of Chinese cabbage root swelling disease,followed by 3.0 and 4.5 L·hm-2. As application rate of fluridine increased,Chinese cabbage yield exhibited a "initial increase followed by decline" trend,with the highest yield achieved at 1.5 L·hm-2 treatment,showing a 22.2% increase compared with the control. In summary,the optimal fluridine application rate for greenhouse vegetables production is 1.5-3.0 L·hm-2.
