Soil was found to be a slight carbon sink during recovery processes in the agro -pastoral area of the northern Loess Plateau with SOCD, being （2.11 kgCm-2） in scrubland 〉（1.95 kgCm-2） in secondary m-2 ） in artificial grassland 〉（ 1.69 kgCm-2 ） in abandoned farmland and 〉（1.68 kgCm-2） in farmland.

以黄土高原北部水蚀风蚀交错带地区不同生长年限的紫花苜蓿人工草地及其退化后形成的次生草地为主要研究对象，探讨了SOCD的动态变化特征。

The purpose was to study the effect of alfalfa and smooth brome grass with different mix-sowing ratio on silage quality.

［目的］研究不同比例的无芒雀麦与紫花苜蓿混播对青贮效果的影响。

The present thesis showed that root elongation of alfalfa (Medicago sativa L.) during a 24-h period was inhibited by 80% by the exposure to 5 umol L-1 Al and its roots was obviously stained by eriochrome cyanine R; however, the roots of stylo need to be exposure to 30umol L-1 Al in order to get obviously stained with its root elongation was inhibited by 68%, which shows, for stylo, its ability of tolerance to aluminum is strong.

本研究发现，5 μmol L~(-1)AlCl_3使紫花苜蓿根长抑制80.0％，铝处理后的根尖被铬天青明显染色，而柱花草经30 μmol L~(-1)的AlCl_3处理后方观察到根尖明显染色的现象，根的伸长受抑制68.0％，表明柱花草抵御铝毒能力较强。

The following crop plants are generally considered susceptible to sulfur dioxide: alfalfa, barley, buckwheat, clover, oats, pumpkin, radish, rhubarb, spinach, squash, Swiss chard and tobacco.
