Effects of Different Rhizobia Strains and Culture Substrates on Nodulation and Nitrogen Fixation of Two Faba Bean Varieties"Yunzao No.15"and"Lingxiyicun"in Yunnan Province
摘要
Abstract
[Objective]The substitution of vegetables with faba beans,coupled with the screening and inoculation of highly efficient nitrogen-fixing and broadly adaptive rhizobia,holds promise for fostering the sustainable development of vegetable-tobacco continuous cropping.[Meth-od]Two pot experiments were conducted,employing two faba bean varieties cultivated in Yuxi City,which named"Yunzao No.15"(YZ-15)and"Lingxiyicun"(LX-1).High-efficiency and high-compatibility rhizobia from 10 rhizobia strains with diverse genetic backgrounds were screened.For designated efficient rhizobia strains,a comparison of the effects of three different culture substrates on nodulation and nitrogen fix-ation was carried out.The shoot dry weight,root dry weight,SPAD,nodule number and nodule dry weight were measured.[Result]Compared with the control,the nodule number,nodule dry weight,shoot dry weight,root dry weight and SPAD of faba bean were significantly increased af-ter inoculation with the above 10 rhizobia strains.The symbiosis between"Yunzao No.15"with YX-2-26,WS-1-13,YL-1-23 and YL-1-35 ex-hibited significantly better effects than with the other 6 rhizobia strains,while the symbiosis of"Lingxiyicun"with WS-1-13,YX-2-26 and WS-1-18 was more favorable.Co-inoculation of WS-1-13 and YX-2-26 demonstrated excellent nodulation and nitrogen fixation effects in soil sub-strate that better than those in vermiculite substrate,leading to a significant increase in nodule number,nodule dry weight,shoot dry weight,root dry weight and SPAD.[Conclusion]This study successfully screened two rhizobia strains with high efficiency,broad-spectrum compatibility and strong adaptability,providing high-quality germplasm resources for the development and application of faba bean rhizobia inoculant in Yunnan Province.关键词
