摘 要:通过盆栽试验,探究不同浓度长枝木霉菌拌种后对绿豆开花期、结荚期和成熟期农艺性状的影响。以小明绿为试材,于生长季5—8月期间比较菌种比为0%(LCK)、0.5%(LA)、1%(LB)、2%(LC)、3%(LD)共5种处理对绿豆植株的促生作用。结果表明:0.5%菌种比处理在开花期对绿豆的生长指标促进作用明显;2%、3%菌种比处理在结荚期和成熟期表现优异;干物质积累与株高、根长、叶绿素含量、根冠比、地上含水率呈极显著正相关,与地下含水率呈极显著负相关。由此可见,高浓度木霉菌处理更利于绿豆生长。

Abstract: In order to promote the application of Trichoderma green prevention and control, the effects of different concentrations of Trichoderma long on the agronomic traits of mung bean at the flowering, pod bearing and maturity stages were investigated through pot experiment using Trichoderma long as experimental material. With Xiaoming Green as the test material, during the growing season from May to August, the promoting effect of 5 treatments with 0% (LCK), 0.5% (LA), 1% (LB), 2%(LC) and 3% (LD) on mung bean plants was compared. The results showed that 0.5% bacterial strain had a significant effect on the growth index of mung bean at the flowering stage. The 2% and 3% strains showed better performance in pod - bearing and mature stage.Dry matter accumulation was significantly positively correlated with plant height, root length, chlorophyll content, root-cap ratio and overground water content, while negatively correlated with underground water content. Pot experiment showed that high concentration of Trichoderma was more beneficial to mung bean growth.

绿豆[Vigna radiata(linn.)wilczek],又名青小豆、植豆,属一年生直立草本[1]。绿豆首载于宋朝的《开宝本草》,有“绿色珍珠”的美譽[2],具有极高的食用和药用、保健价值。近年来,绿豆需求量逐年增加[3],如何绿色高效种植绿豆已成为目前绿豆种植研究的重点之一。研究发现,木霉菌(Trichoderma)具有产效双增的效果[4],不仅可以修复土壤环境、防治病害,还能促进植物生长[5]。而且,当外源植物生长调节剂浓度过高对植物产生药害时,木霉菌还能降低这种抑制作用;当浓度处于低水平时,木霉菌还可起到促进作用,这种双向调节对于作物生长意义重大[6]。目前,木霉菌在辣椒、黄瓜、草莓等园艺作物和水稻、玉米等农作物、林木、中药材等都得到应用并且促生效果显著[7-14],然而木霉菌对绿豆生长的影响尚未见报道。笔者采用……
