摘要
以设施番茄幼苗为试材,研究了"五丰-B6"、"五丰-001"、"五丰-002"3种自主研发的微生物菌剂对番茄幼苗株高、茎粗、冠幅、叶片数、叶绿素含量等指标的影响,以不添加任何成分为对照1(CK1)、生长调节剂S-诱抗素为对照2(CK2)。结果表明:3种微生物菌剂以及生长调节剂S-诱抗素对番茄幼苗的生长均具有一定促进作用,处理后的番茄幼苗各项生长指标与对照1存在显著差异;"五丰-B6"菌剂处理的番茄幼苗株高、茎粗、叶绿素含量均显著高于对照1(CK1)以及生长调节剂S-诱抗素(CK2),分别比对照株高、茎粗、叶绿素含量分别增加22.36%、34.03%、11.23%;"五丰-001"菌剂在增加植株冠幅方面表现显著,分别比生长调节剂S-诱抗素(CK2)增加8.30%,比CK1增加14.62%;综合各菌剂以及S-诱抗素对番茄幼苗生长影响的程度,依次为"五丰-B6">"五丰-001">"五丰-002">"生长调节剂S-诱抗素">CK1。
Taking the facilities tomato seedlings as experimental material, the effects of the control （CK1）, growth regulator S-induced resistance factors（CK2） and 3 bacterial strains （＇ WF-B6＇ ;＇ WF-001 ; and ＇ WF-002 ＇ ） on the tomato seedling plant height, stem diameter, crown width, leaf number, leaf chlorophyll content index were studied. The results showed that all the 3 microbial agents and the S-induced resistance factors（CK2） significantly enhanced tomato seedling growth as compared with the control treatment. Tomato seedlings treated with microbial agent ＇WF- B6; were significantly higher than the control in plant height, stem diameter and chlorophyll content. ＇WF-001＇ was the best in promoting the crown width extension, which was 14. 62 % higher than the control,and 8. 30 ; higher than the S-induced resistance factors （CK2）. Based on the comprehensive comparison, the effectiveness of the tested microbial agents and chemical agent on the tomato growth follows the order.＇ WF-B6 ＇〉 ＇ WF-001 ＇ 〉 ＇ WF-002 〉S-induced resistance factors CK2〉CK1.
