According to the macro-characteristics and distribution law of dioritic microgranular enclaves, the special texture and structure, the contrast between the main rock-forming minerals of dioritic microgranular enclave and the host rock, as well as the genesis analysis on double crystal type percentage of 6 187 plagioclase, the conclusion is drawn as follows: despite the variety of the genesis types of dioritic microgranular enclave in Fangshan granodiorite, most of the genesis type is probably the result of the xenolith metamorphic transformation.

根据闪长质微粒包体的宏观特征及分布规律、特殊的结构构造、主要造岩矿物与寄主岩的对比以及6187个斜长石双晶类型百分率的成因分析得出，房山花岗闪长岩体中的闪长质微粒包体尽管有多种成因，但有不少可能是捕虏岩包体变质改造的结果。

The pot experiment results showed that inoculation with A1501 and A1513 could promote the growth and grain yield of rice. Comparison with the non\|inoculation, the grain yeild of rice treated with A1501 and A1513 increased by 8 5% and 10 3% respectively. And %Ndfa of rice shoot and grain estimated by 15 N\|isotope dilution method was 9 00% and 11 5%, respectively, which was consistent with the increment of the total N(8 5% and 11 6%,respectively).

盆栽结果表明，接种A.faecalis 显著提高了水稻的生长，接种A1501 和A1513 的水稻稻谷产量分别比未接种提高了85％和103％，用15N 同位素稀释法估测水稻地上部总氮中来源联合固氮的百分率达900％和115％，其结果与水稻地上部总氮量的增加幅度（86％和116％）基本一致。
