The results showed that the both two plasmids could stablely maintained in 7653R under both free-living and symbiotic conditions and the stability was up to 100%.

结果表明：在自生与共生条件下，供试标记质粒在华癸中生根瘤菌中均能稳定存在，且稳定性达到100％。

The application of rhizobia inoculant can drastically reduce the dose of chemical nitrogen fertilizer and decrease the environmental pollutions.

使用根瘤菌剂接种豆科作物可以大幅减少化学肥料的施用量，降低环境污染。

In addition, production methodologies, formulations and quality control of non-rhizobial inoculant are not well developed, thereby reducing the chance that farmers can purchase a product beneficial to crop production.

另外，对非根瘤菌剂的生产方法、配方及质量控制还有待进一步的研究。所有这些都降低了农民购买对作物生产有利的产品的机会。
