摘　　要：以17%多福悬浮剂和20%福克悬浮剂2种种衣剂为供试材料,以辣椒为试验对象,进行温室大棚栽培试验,确认种衣剂使用的安全性,研究其对辣椒出苗、生长、果实品质及其根际土壤微生态的影响。结果表明:多福和福克对辣椒出苗和苗期生长均无显著影响,而多福影响辣椒现蕾期和开花期株高的生长,分别比对照减少4.60%和9.12%;多福减少开花期叶绿素含量,而福克无显著影响,多福和福克均显著影响辣椒根系活力,福克对根系活力的影响更为显著,在苗期、现蕾期和开花期分别比对照降低33.72%、78.05%和55.88%;多福和福克均降低辣椒品质相关指标中的硝态氮含量,分别比对照降低35.09%和27.94%;多福和福克不同程度影响辣椒根际土壤微生态,苗期和现蕾期对辣椒根际土壤脲酶、磷酸酶和过氧化氢酶活性的影响比较明显,多福和福克不同程度减少辣椒根际土壤细菌数量,而增加真菌数量;多福减少辣椒根际土壤速效磷的含量,而福克没有显著影响。To confirm the application safety of 17% Carbendazim · Thiram and 20% Thiram ·Carbofuran suspensions on pepper,cultivation experiment in plastic house was conducted to study the effects of the two seed coating agents on pepper germination,growth,fruit qualities and the micro ecology in the rhizosphere soil.The results showed that Carbendazim · Thiram and Thiram ·Carbofuran had no significant adverse effects on pepper germination and seedling growth,while compared with control,Carbendazim · Thiram decreased the height of pepper at squaring and flowering stage by 4.60% and 9.12% respectively;Thiram · Carbofuran reduced the content of chlorophyll at flowering stage,while Thiram·Carbofuran had no significant effect on the content of chlorophyll;both seed coating agents had significant effects on root activity of pepper,and compared to control,Thiram·Carbofuran decreased the root activity at seedling,squaring and flowering stage by33.72%,78.05% and 55.88% respectively;compared to control,both Carbendazim· Thiram and Thiram·Carbofuran decreased the content of nitrate nitrogen in pepper fruit by 35.09%and 27.94%respectively;Carbendazim·Thiram and Thiram·Carbofuran influenced the micro ecology of pepper rhizosphere soil to different degrees,with significant effects on the activities of urease,phosphatase and catalase in the rhizosphere soil of pepper at seedling and squaring stage;Carbendazim·Thiram and Thiram·Carbofuran decreased the amount of bacteria in the rhizosphere soil of pepper to different degrees,while increased the amount of fungi;Carbendazim·Thiram decreased the content of available phosphorus in the rhizosphere soil of pepper,while Thiram·Carbofuran had no significant effect on available phosphorus.
