本文针对栽培花生，从大、小共生体双方研究了寄主植物─根瘤菌株组合的亲和性。结果指出：（１）在温室水培盆栽条件下，用菌株１４７－３接种的寄主植物结瘤、固氮能力育成品种＞普通型；（２）血清学鉴定出５个不同血清型菌株，其竞争力或回收率与寄主品种、根瘤菌株和土著菌数密切相关；（３）在温室与田间条件下，不同花生寄主─根瘤菌株组合存在着广谱或特异共生亲和性与非亲和性的差异，并鉴定出高效、广谱亲和的品种徐州６８－４和菌株１４７－３；（４）强亲和的品种─菌株组合比非亲和组合或不接种（对照）显著增产（Ｐ＜０．０５）。统计１９８７─１９９０年７省共２０５个点的亲和组合接种与不接种对比产量的结果，其增产频率为９７％，平均增产４２１．５ｋｇ／ｈａ，增产率１５．１％。现已在我国推广应用１０．１万公顷，获得明显的经济效益
In this paper, the compatibility of the host plant-rhizobium strain was studied from both large and small symbioses for peanut cultivation. The results showed that: (1) The nodulated and nitrogen-fixing ability of the host plants inoculated with strain 147-3 was> common in hydroponic pot culture in greenhouse; (2) Five serotype strains were identified by serology, Force or recoveries were closely related to host species, rhizobia strains and indigenous bacteria. (3) Broad-spectrum or specific symbiotic affinity and non-affinity of different peanut host-rhizobia strains under greenhouse and field conditions Differentiated, and identified high efficient, broad-spectrum affinity varieties Xuzhou 68-4 and strain 147-3; (4) Strong-affinity variety-strain combination significantly increased compared with non-affinity or non-inoculation (control) 0.05). Statistics From 1987 to 1990, a total of 205 spots in 7 provinces were used for inoculation and non-inoculation. The yield of the combination was 97% with an average yield of 421.5kg / ha and an increase rate of 15.1%. Now in China promote the use of 101,000 hectares, access to significant economic benefits
