摘要
【目的】研究不同根瘤菌接种方式对复播大豆生长及结瘤效果。【方法】以前期分离、鉴定、纯化的3株根瘤菌菌株为材料,对新疆南疆地区复播大豆新大豆8号进行种肥、随水滴施、拌种等接种方式试验,测定其根瘤数、根瘤干重、植株性状、产量及其构成因素的变化。【结果】接种根瘤菌均能促进大豆根系结瘤和生长发育,根瘤菌SN7-2促进效果最明显,其次是SMH12;根瘤菌接种方式中,根瘤菌拌种处理效果最好,其次是随水滴施。其中拌种SN7-2处理组合产量最佳达到3575.23 kg/hm^(2),拌种SMH12处理组合产量次之,达到3376.03 kg/hm^(2)。【结论】较好的根瘤菌和接种方式组合分别是根瘤菌SN7-2和SMH12拌种,其次是根瘤菌SN7-2滴施。
【Objective】To explore the effect of different rhizobia inoculation.【Method】On the growth and nodulation of the multiple sowing soybean,three rhizobia strains(NW5-3,SN7-2 and SMH12)were used as materials,and three inoculation methods of seed fertilizer,application with drip irrigation and seed dressing were carried out on soybean Xindou 8 in southern Xinjiang,the nodule number,nodule dry weight,plant traits,yield and the yield components were measured.【Result】Inoculation of rhizobia could promote root nodulation and growth of soybean,and the SN7-2 performed better than the SMH12 and NW5-3.Among the inoculation methods,the seed dressing treatment of rhizobia was the most suitable,followed by application with dripping water.Among them,the optimal yield of the seed dressing SN7-2 treatment combination reached 3,575.23 kg/hm^(2),seed dressing SMH12 treatment combination yield second reached 3,376.03 kg/hm^(2).【Conclusion】Under the experimental conditions,the most suitable match was the combination of seed dressing with rhizobia SN7-2 and SMH-12,followed by drip application with rhizobia SN7-2.
