摘要:

探讨不同根瘤菌接种方式的实施效果,以前期分离、鉴定、纯化的3株根瘤菌菌株为供试材料,选用南疆地区复播大豆绥农35为供试品种,比较根瘤菌拌种、做种肥、随水滴施等接种方式的效果,测定大豆结瘤数量、根瘤干重、植株地上部干物质积累分配、产量及其构成因素等指标,探讨接种方式和根瘤菌对复播大豆干物质积累及产量的影响。结果表明,3种接种方式均能促进大豆根系结瘤,其中,以SN7-2拌种、SMH12做种肥,SN7-2做种肥和T6随水滴施大豆根瘤菌结瘤效果最好;SN7-2拌种,SMH12做种肥,SN7-2做种肥,T6随水滴施能显著促进大豆干物质积累,SN7-2拌种或者SN7-2做种肥、T6随水滴施均促进干物质向生殖器官分配;不同接种方式通过增加主茎节数、单株荚数、单株粒数和百粒重提高大豆籽粒产量,SN7-2适合以拌种或做种肥的方式接种,T6适合随水滴施。

Abstract:

To explore the effects of different modes of rhizobium inoculation on the biomass accumulation and the yield, three isolated, identified and purified rhizobium strains, and multiple soybean varieties of SUINONG35 was selected as materials, the effects of the three rhizobium inoculation application methods of seed dressing, seed fertilizer, and drip application on the rhizobia nodule number, dry weight of root nodules, aboveground dry matter accumulation and distribution, yield and its composition were compared. The results showed that the rhizobium inoculation could promote the nodule formation of soybean roots, among which, seed dressing inoculation method of SN7-2, seed fertilization inoculation method for SMH12 and SN7-2, and drip inoculation for T6 had the best nodule effect. Seed dressing inoculation method of SN7-2, seed fertilization inoculation method for SMH12 and SN7-2, and drip inoculation for T6 coiled significantly promote the dry matter accumulation of soybean. Seed dressing method and seed fertilizer inoculation method of SN7-2, and drip inoculation method for T6 could promote dry matter distribution to reproductive organs. The seed yield of soybean improved by increasing the number of main stem nodes, pod number per plant, grain number per plant and 100 grain weight with different inoculation methods. The seed dressing method and seed fertilizer method were suitable for the SN7-2, whilst, for the T6, the suitable application method was dripping.
