摘要
[目的]验证阿根廷利索公司大豆根瘤菌剂与北方大豆主栽品种的结瘤能力。[方法]以黑河43号为供试品种，采用完全随机区域排列方式，设5个处理，每个处理用不同的大豆根瘤菌剂( Rizoliq Top、Rizoliq Top + Premax、Signum +Premax-Signum、LLI + Premax-LLI)进行拌种，调查大豆植株的生长性状和小区产量。[结果] Rizoliq Top菌剂数量为国家标准最低标准的5.2倍；包衣后种子带菌量为5.48×104 CFU/mL；菌剂Rizoliq Top+Premax和LLI + Premax-LLI在荚数、粒数、百粒重方面与对照相比差异不显著，但均高于对照，产量显著高于对照，分别增产14.32%和22.96%。[结论]大豆根瘤菌Rizoliq Top+Premax和LLI+Premax-LLI与黑河43号相互适配性好，增产效果显著。 Signum+Premax-Signum和Rizoliq Top与黑河主栽品种黑河43号大豆适配性差或不适应黑河环境，导致增产效果不理想。
Abstract
Objective] To test the nodulation ability of rhizobia inoculants produced by Rhizobacter Argentina S. A. to nodulate host legume plants of main soybean cultivar in the north of China. [ Method] By adopting the randomized complete block design, five treatments were de-signed with Heihe 43 as the tested varieties. Different soybean nitragins ( Rizoliq Top, Rizoliq Top + Premax, Signum +Premax-Signum, LLI+ Premax-LLI) were used for each treatment. The growth traits and plot yield of soybean plant were investigated. [ Result] Rizoliq Top was 5. 2 times of the minimum standards in national standards. The number of rhizobium after coating was 5. 48 × 104 CFU/mL. Rizolip Top+Pre-max and LLI+Premax-LLI were higher than CK in pod number and seed number per plant and 100-seed weight, but there were no significant differences. The yields were obviously higher than that in CK, which increased by14. 32% and 22. 96%, respectively. [Conclusion] Rizoliq Top+Premax and LLI+Premax-LLI have a good mutual compatibility with Heihe 43, showing significant yield increasing effects. The unsatis-factory performances of Signum+Premax-Signum and Rizoliq Top are possibly due to their poor adaptation to Heihe43 which is the main soy-bean cultivar, or they are not suited to climatic conditions of Heihe city.
