小叶锦鸡儿(Caragana microphylia)是一种极抗寒和抗旱的豆科植物,既能防风固沙、保持水土,又可为畜牧业提供优质饲料,是干旱草原、荒漠草原植被恢复的先锋植物。本研究通过施用地木耳提取液及根瘤菌菌剂对小叶锦鸡儿幼苗的生长进行了研究。结果表明,2种微生物制剂对该植物的生长均具有显著的促进作用,田间栽培试验中,根瘤菌菌株HBU037001接种种子出苗率高达91.1%;地木耳提取液1/20原液浓度、菌株HBU037002处理的小叶锦鸡儿幼苗生物量分别比对照提高11.5%和17.7%;地木耳提取液1/10原液浓度+菌株HBU037001的联合处理表现最好,可提高植物生物量高达28.2%。
Caragana microphylia is a very hardy and drought-resistant legume that can not only wind and sand, maintain soil and water, but also provide high-quality feed for animal husbandry. It is also a pioneer plant in arid grassland and desert steppe restoration. In this study, the growth of Caragana microphylla seedlings was studied through the application of the extract of Agrocybe aegerita and rhizobia. The results showed that the two kinds of microbial agents had a significant promoting effect on the growth of the plants. In the field experiment, the inoculation rate of the inoculated seeds of Rhizobium strain HBU037001 was as high as 91.1%; the concentration of 1/20 of the Ammopiptanthus nivalis extract and the strain HBU037002 The biomass of Caragana microphylla seedlings increased by 11.5% and 17.7% respectively compared with that of the control. The combined treatment of 1/10 stock solution of Auricularia Auricular and strain HBU037001 performed the best, which could increase the plant biomass up to 28.2%.
