方法通过田间试验，研究在高寒地区种植紫花苜蓿后其土壤中有机质、氮素、磷素、钾素等养分的变化情况。

To understand the adaptability and ion regulation mechanisms of Medicago sativa, Melilotus officinalis, and Astragalus adsurgens seeds at their germination stage to saline environment, the seeds were treated with different concentrations of NaCl, and their germination rate and recovery germination rate ere determined. In the meantime, the changes of main ions contents in seed embryos and the water uptake by the embryos at 400 mmol L^(-1) of NaCl were investigated.

试验对3种豆科牧草紫花苜蓿、草木樨、沙打旺的种子，在萌发阶段对盐渍环境的适应性和离子调控机制进行了研究，测定了盐渍环境中种子的萌发率和恢复萌发率；同时，对400mmolL^(-1)NaCl处理后，种子恢复萌发、胚的主要离子含量变化、水分吸收等情况进行了测定。

The representative strain SDW018 of group Ⅲ nodulated Phaseolus vulgaris, Vigna unguiculata, Glycine max, Leucaena leucocephala, Medicago sativa, Lotus corniculatus. The other tested strains nodulated 1 to 3 leguminous plant species respectively.

群Ⅲ的代表菌株SDW018可与菜豆、豇豆、大豆、银合欢、紫花苜蓿、百脉根等结瘤。

Soil noncapillary porosity of model two had the maximum in soil surface(11.11%) and decreased with soil depth increased.

仁用杏+紫花苜蓿和仁用杏+红豆草模式地土壤非毛管孔隙度随土壤深度有先增后减的趋势，在40cm层达到最大值(分别为：6.46%，5.65%)。

The increased amount of non--exchangeable NH4^＋-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^＋-N （P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively）. NH4^＋-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^＋-N increased significantly when added （NH4）2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^＋-N from （NH4）2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^＋-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d （P=0.0434）, but not significantly at 40 d and 60d （P=0.7378 and 0.5375）. The increased amount of non-exchangeable NH4^＋-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^＋-N, the increased amount of non-exchangeable NH4^＋-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.

培养期间非交换性NH4^＋-N的增加量均表现为以土垫旱耕人为土最大，其次是黄土正常新成土，简育干润均腐土和干湿砂质新成土较小；添加有机物料极显著影响培养期间的非交换性NH4^＋-N增加量（培养20d、40d和60d时P分别为0.0002，0.004和0.0003），表现为紫花苜蓿和长芒草土壤非交换性NH4^＋-N的增加量均极显著高于不添加有机物料的对照土壤；在培养20d、40d和60d时，加（NH4）2SO4土样非交换性NH4^＋-N的增加量显著大于不加（NH4）2SO4土样（户分别为0.0037，0.0033和0.0027），这是土壤对（NH4）2SO4中NH4^＋-N固定的必然结果；不同植被类型土壤培养20d时的非交换性NH4^＋-N增加量差异显著（P=0.0434），培养40d和60d时差异不显著（p分别为0.7378和0.5375）；长期秸秆和氮肥配施土壤非交换性NH4^＋-N增加量大于不施肥对照土壤，但差异不显著土壤黏粒、全氮和有机质与培养0d、20d、40d和60d时土壤的非交换性NH4^＋-N含量均呈极显著正相关；而非交换性NH4^＋-N的增加量与粘粒无相关性，但与全氛和有机质呈显著正相关。
