Pretreatment promotes the enzymatic saccharification and fermentation of alfalfa, sorghum hybrid sudan grass, pearl millet, and erect milkvetch, and their energy performance decreases in order.

结论］预处理促进了紫花苜蓿、高丹草、御谷、沙打旺的酶解糖化发酵，4种牧草的能源性依次降低。

In addition, the inhibition effect on the elongation of radicle is higher than that on germ.

总体来看，紫花苜蓿对Cu污染的耐受程度大于红三叶和沙打旺。

The conclusion show as followings: Based on parameter recension of EPIC model, the correlation coefficient between simulated alfalfa forage yield and root zone soil water with observed value were 0.8957 and 0.9884, the correlation coefficient between simulated A.

2半湿润区紫花苜蓿30年的水分生产潜力模拟值为4.262～13.456t/hm~2，根层有效水含量在第8年达到极低值，受土壤水分降低的影响，苜蓿的水分生产力水平开始降低，干旱胁迫日数开始加重，且分别与当年和前一年的降雨量成正相关和负相关变化。

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.

一下农作物通常被认为是易受二氧化硫感染的：紫花苜蓿，大麦，荞麦，三叶草，燕麦，南瓜，萝卜，大黄，菠菜，唐莴苣，烟草。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
