摘要：

为探讨施用丛枝菌根真菌(Arbuscular Mycorrhizal Fungi, AMF)及深色有隔内生真菌(Dark Septate Endophytes,DSE)菌剂对生姜生长的影响,以生姜为研究对象,选择AMF菌剂、DSE菌剂以及AMF+DSE混合菌剂进行大田试验,于生姜发根期采集生姜根系样品,进行根系侵染检测,于生姜收获期对生姜的产量及农艺性状进行相关分析。相对于空白对照,无论是单一功能微生物菌剂还是AMF+DSE混合菌剂,都会促进生姜的生长以及减少姜瘟病的发生;无论是单一菌剂还是复合菌剂都能侵染生姜根系,都能在生姜根系内定殖。大田施用不同微生物菌剂能显著提高生姜的产量,并增加生姜植株株高、分枝数、单株重以及降低病害的发生。其中,AMF+DSE混合菌剂处理的产量最高,为3257 kg/hm2,其次是AMF菌剂处理和DSE菌剂处理,分别为2725 kg/hm2、2402 kg/hm2,比对照产量1997 kg/hm2分别增产38.7%、26.7%、16.8%。对照的发病率最高,达到54.2%,而施用AMF+DSE混合菌剂、AMF菌剂和DSE菌剂的发病率分别为5.24%、8.27%、11.5%,明显降低了姜瘟病的发生。

Abstract:

The study aims to investigate the effects of arbuscular mycorrhizal fungi (AMF) and dark septate endophytes inoculum (DSE) on ginger growth. The ginger was used as material, and AMF, DSE and AMF+DSE combination were conducted in this study. During the rooting period, ginger root samples were collected for inoculation detection. The ginger yield and agronomic characters were analyzed with correlation analysis. Compared with the control, all treatment types (AMF, DSE and AMF+DSE combination) promoted ginger growth and decreased the occurrence of ginger wilt. Successful inoculation and colonization by AMF, DSE and AMF+DSE combination were confirmed in ginger roots. Application of microbial agents could effectively promote the growth of ginger and decrease the occurrence of ginger wilt. The highest ginger yield was achieved in the combination treatment with AMF and DSE (3257 kg/hm2), followed by AMF alone (2725 kg/hm2) and DSE (2402 kg/hm2). In comparison, the control resulted in a yield of 1997 kg/hm2. The yield increase was 38.7%, 26.7%, and 16.8% respectively for the combination treatment, AMF, and DSE. The control had a disease occurrence rate 54.2%, in contrast, the treatment groups exhibited a lower disease occurrence rate, with 5.24%, 8.27%, and 11.5% respectively for the combination treatment, AMF and DSE.

Key words: ginger, arbuscular mycorrhizal fungi, dark septate endophytes, microorganisms, agronomic characters
