哈茨木霉SQR-T037对茄子幼苗促生效应的研究

摘要

[目的]为研究木霉SQR-T037对茄子幼苗的促生效应.[方法]以“种都墨茄”为试验材料,采用盆栽土培的方法,设无机肥CK、有机肥OF、哈茨木霉SQR-T037菌液灌根3个处理.[结果]木霉SQR-T037菌液灌根处理相对于无机肥CK和有机肥OF处理能在0.05水平显著提高茄子生物量,但对茄子叶片的叶绿素SPAD值和POD活性无明显影响；SQR-T037菌液灌根处理对茄子根系的生长无明显的促进作用,但对茄子幼苗的根系活力有一定的促进作用；SQR-T037菌液灌根处理能在0.05水平显著增加茄子幼苗的干物量积累.[结论]木霉SQR-T037对茄子苗期的生长具有显著的促生效应.%[Objective]The research aimed to study the growth-promoting effect of SQR-TO37 on eggplant seedlings. [ Method] With Zhongdu ink eggplant as the experimental material, through pot-cultivation, three treatments were set as chemical fertilizer-CK, organic fertilizer-OF and fermentation broth of T. harzianum SQR-T037 to fill the roots. [ Result ] The fermentation broth of T. harzianum SQR-T037 treatment could obviously improve the biomass of eggplant seedlings compared with CK and OF treatment, ,but it had little effects on chlorophyll content of eggplant leaf, SPAD value nor POD enzyme activity. SQR-T037 fermentation broth had no obvious effects on the growth of root system, but it could increase the root activity of eggplant seedlings. SQR-T037 treatment could extremely increase the dry matter accumulation of eggplant seedlings. [ Conclusion] The growth-promoting effect of SQR-T037 on eggplant seedlings is obvious.
