黄壤

It showed that the inverse circular function equation had the best fitting to the process of yellow soil releasing cadmium at conditions with different acid rain. Besides, polynomial equations and two-constant equations can also describe this process properly.

结果表明，反三角函数方程对多种酸雨条件下黄壤吸附态镉释放过程的拟合度最佳，此外多项式方程、双常数方程也能较好地描述这一过程。

Relati/onships between the relative height and the mean velocity explain that the effect to slow the velocity down of Centipede grass is the best, that of Bermuda grass is the second, and that of Carpet grass is the worst whatever the bottom is yellow loam or red loam.

经实验结果推得理论解合理，由相对高度与流速之关系图可看出：在土壤为黄壤及土壤为红壤的状况下，减缓流速效果皆以假俭草为最佳、百慕达草次之，最差者为类地毯草。

The yellow soil, fly ash and sand and stone are analyzed for their abilities of clearing from the impurities to choose the best combination of soil stuffing, in which stuffing is 60cm thick, fly ash covers 5 percent ,and sand and stone are in the ratio of 3 to 1. The acclimated activated sludge added to the soil stuffing in two ways, the PVC tube used which is 160 cm high and whose inside diameter is 110cm, the pint-sized soil stuffing columniation is set up in the lab.

对所选黄壤、粉煤灰、砂石的去污能力进行分析，最终确定粉煤灰投加量为5%、土：砂质量比为3：1为最佳的土壤填料组合，土壤填料厚度为60cm，并以两种方式将驯化的活性污泥添加到土壤填料中，采用内径为11cm、高160cm的PVC管建立起实验室小型的土壤填料柱系统。

Six cultivars of Vaccinium ashei were grown on acid yellow soil, which were introduced from Jiangsu Institute of Botany in March 2000. All cultivars grew well and began to come into blossom and bear fruit in the following year.

摘 要：2000年3月从江苏植物研究所引进美国兔眼蓝浆果6个品种在贵州麻江县酸性黄壤上试种，2001年试花结实，2002年全部单株挂果。

Meters above sea level there is a large area below the distribution of pine forest, Shan-lin, Mao bamboo, soil is red soil (500 meters) and yellow (50-800 or 100 meters); 800 meters above the Huangshan pine and chestnut, chemical incense, bubble tree forests, mountain yellow brown soil; 1500 meters above the grass, mountain meadow soil coppice.

海拔80米以下分布有大面积马尾松林、杉林、毛竹林，土壤为红壤（500米以下）和黄壤（50—800或100米）；800米以上为黄山松林及锥栗、化香、泡树次生林，山地黄棕壤；1500米以上为草丛，山地矮林草甸土。

Soil sampled including red soil and yellow soil is obtained from Liping County and is covered by different vegetations such as Phyllostostachys pubescens, Cunninghamia lanceolata (8,12,14,60 years), Shrubs, Broadleaf, Camellia Oleifora Abel, Couch grass and Pine trees.

本论文的研究材料来自贵州省黎平县，分别在红壤和黄壤主要土壤类型上，按照不同人工林，分为毛竹，杉木(8年)，杉木(12年)，杉木(16年)，杉木(40年)，灌木林，阔叶林，油茶，茅草，松树共16个处理。

Meanwhile with increasing the total amount of leaching water (250mL~750mL), the gross of 5Zr in leaching water changed indistinctively, which indicated that once 95Zr was absorbed by soils, it was very difficult to unbind by water.

刁。4cm土层范围内，红黄壤和海泥则分别为%。02%一97.16%和95.94%~98.01%；(3)随淋溶水盐度的增加，表层土(0一0.2cm)中952：的量明显提高，表明水体盐度增加有助于提高土壤对952：的吸附率。3、研究了卿鱼对952：的吸收和在其体内的分布动态以及95Zr在水生生态系统中的行为特性，并运用非线性拟合方法建立其数学模型。

Results showed that high quality black tea was mainly produced in red soil, red yellow soil and intermountain alluvial terraces formed by fluvial outwash, with loose soil texture and high soil organic matter content.

分析表明，优质红茶产地主要是红壤、红黄壤和河流冲积形成的山间冲积台地，土壤质地疏松，有机质含量较高。

Compared carbon pools and turnovertime under different soil types, the result shows: soil total organic carbon is grey cinnamonforest soil＞dark-brown soil＞meadow soil＞brown coniferous forest soil＞red soil＞yellowsoil＞yellow brown soil＞paddy soil＞red soil＞flubo-aquic soil＞fengsha soil,temperate forest soil＞subtropical forest soil＞subtropical cropland soil＞temperate dry soil.Active carbon is temperate forest soil＞subtropical soil.

对不同土壤类型的碳库及其驻留时间进行比较，得出：有机碳含量呈现：灰褐土＞暗棕壤＞草甸土＞棕色针叶林土＞红壤＞黄壤＞黄棕壤＞水稻土＞农田红壤＞潮土＞风沙土，温带森林土壤＞亚热带森林土壤＞亚热带农田土壤＞温带干旱土壤；活性碳含量是温带森林土壤＞亚热带的土壤。

In purplish soil, the number of dominant microbial populations in the rhizosphere was greater than in the other two soils, and the population diversities of bacteria and actinomycetes were even greater and more constant, suggesting that the community structures of microorganisms in neutral purplish soil were more reasonable than in both yellow earth and yellow rendzina, which was probably related to the low incidence of tobacco bacterial wilt in the neutral purplish soil.

烤烟根际微生物的种群多样性及其变化在不同土壤中表现也不一样，相对于黄壤和黄色石灰土，在中性紫色土中，根际微生物的优势种群数目较多，根际细菌和放线菌种群更具多样性，而且较稳定，表明其群落结构更为合理，这可能与中性紫色土上的烟草青枯病发生率较低有一定关系。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
