A broad expanse of the river was turned to blood;1 in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous;2 in one place a long, slanting mark lay sparkling upon the water; in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced; the shore on our left was densely wooded, and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun.

不远处红光闪成金黄；孤零零的一根原木在河中漂浮而来，呈一线醒目的黑色；河的一处，一条长长的斜影横落在水面上，闪闪烁烁；另一处，水面被翻滚的水波打碎，仿佛蛋白石放射的斑斓色彩；红彩最淡处是一片平静的水面，覆盖着优雅的环形和放射状的波纹，细腻如绘；河左岸是一片浓密的森林，一条长长的崎岖小径划破树林的一片荫翳，闪闪如银；一株光秃秃的枯树高耸于密林之上，仅剩的一杆青枝随风摇曳，像火焰闪耀在阳光洒下的一览无遗的壮美之中。

After 14D and 28D, Observe the color of the leaves,Count the number of leaves and respectively measure the seedling's height、root long、wet weight、dry weight、relatively water content、chlorophyll content、soluble sugar content、proteid content、nitrate reductase activity and Peroxide enzyme activity to discuss the effect of each element to the tomato seedling.

为材料，进行缺氮、缺磷、缺钾、缺铁的溶液培养，分别在培养14d和28d后观察其叶色，计算叶数并测定了各缺素植株的株高、根长、鲜重、干重、相对含水量、叶绿素含量、可溶性糖含量、蛋白质含量、硝酸还原酶活性和过氧化物酶活性。

The results showed that the POD total activity and isozymes obviously changed after Paulownia trees were infected by witch's broom.

结果表明，泡桐感病后，叶片的POD总活性没有显著变化，枝、根韧皮部的POD总活性。病株高于健株。

The result showed that this strain could colonize in many plants, such as capsicum, tomato, eggplant, cabbage, lettuce, cowpea, wheat, corn and rice.

结果表明：该菌株的内生宿主范围较广，可以通过种子、叶片表面以及根际土壤等进入辣椒、番茄、茄子、白菜、生菜、豇豆、小麦、玉米、水稻等多种植物体内定殖。

Average soil water content had increasing trend during the whole growing stage of cotton, stem height and root length of cotton were increased with the water application rate.

土壤平均含水率在棉花全生育期内有着上升的趋势，在2种滴灌模式下，棉花株高和根长随灌水量的增加而增高。

The results showed that root cutting and potassium application could increase the chlorophyll content of leaves in upper and middle stalk positions, which resulted in larger leaf area and more dry matter accumulation in the leaves.

结果表明：在不同施氮量条件下，打顶时断根追钾促进了烟株中、上部烟叶叶面积的扩展和叶质重的增加，其叶绿素含量尽管高于对照，但没有影响到烟叶的落黄和成熟。

The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.

结果表明，在生长季节内，林内温度低于林外温度，林下人参生长发育较差，产量较低；林分郁闭度为0.7~0.8时，人参的净光合速率、株高、单根重、叶绿素含量等指标较高；而郁闭度过高或过低都会影响人参生长发育；随着人参年龄的增加，净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求，为林下人参生长发育提供最适宜的生态环境。

The ribosomal 16s rDNA of these two strains were amplified and the PCR products were sequenced.

对含有这两个菌株成分的混合生防菌剂GJ23进行对根结线虫的离体生物测定。
