The studies show that Ginseng red coating root disease is a non infectious disease.The direct cause is that under the special soil environment,the Fe2＋,Fe3＋ around the roots is fixed,oxidized and deposited in phellem of the roots,and it cause the changes of the regular physiological and biochemical activities in Ginseng plant,it is a comprehensive action of many factors.

结果表明：人参红皮病为非侵染性植物病害，其发生的直接原因是在特定的土壤条件下，Fe2＋、Fe3＋在参根周皮木栓层固定、氧化沉积和参株不正当的生理生化活动综合作用的结果。

In one heavy thunder-shower the lightning struck a large pitch pine across the pond, making a very conspicuous and perfectly regular spiral groove from top to bottom, an inch or more deep, and four or five inches wide, as you would groove a walking-stick.

在一次雷阵雨中，曾有一道闪电击中湖对岸的一株苍松，从上到下，划出一个一英寸，或者不止一英寸深，四五英寸宽，很明显的螺旋形的深槽，就好像你在一根手杖上刻的槽一样。

The metabolites produced by NJ-08 strain made the leaves of Eleusine indica yellow and wilting, and showed good herbicidal activity against the indicator plant and weeds such as Stylosanthes guianensis, Urena lobata, Crotalaria mucronata and Capsicum frutescens with the inhibition rate to radicel and embryo of above 90%.

NJ-08菌株产生的代谢产物作用于牛筋草，可使叶片黄化或枯死，代谢产物对指示植物及杂草如柱花草、地桃花、猪屎豆和辣椒的胚根胚芽生长都有明显的抑制作用，抑制率均超过了90%，显示出很好的除草活性。

In a word, according to the research of pulp wastewater treatment using pond-reed system, we discovered that the complex system can removal wastewater pollutants effectively, at the same time, the salinity of soil is dramatic decreased through wastewater washing, which bring many active results: increasing of N, P, and organic matter; enhancing of soil microbes, enzymes, MBC/TOC, and soil respire rate; increasing of reed height and yield, decreasing of weed diversity; affecting of transporting ability of Ca, Mg, K, Zn, and Mn , and improving of water shortage, salinity resistance and rhizosphere metabolized secretion conditions, all those improved the weak ecosystem.

总之，经过对生物塘-芦苇湿地系统处理造纸废水的研究，发现系统能有效去除废水中有机物，同时废水灌溉还极大的降低了土壤盐分，产生了一系列积极效应：系统内氮、磷、有机质增加；土壤微生物和酶活性增强；MBC/TOC及土壤呼吸强度提高；芦苇株高和产量增加，而杂草的多样性减少；同时也会影响系统内钙、镁、钾、锌、锰等离子迁移，改变系统受盐碱和缺水胁迫的现状和根际代谢状况，极大地改善了滨海盐碱生态系统现状。

Beneficial bacterium Bacillus subtilis B908, which has distinct control effect for eye-spot disease caused by Rhizoctonia sp., is isolated from rhizosphere of rice.

One cellulase-production strain TC1 was screened. It was identified as Rhizopus sp. based on identification method of fungi.

筛选得到1株纤维素酶产生菌TC1，根据真菌的分类鉴定方法，鉴定为根霉属菌(Rhizopus sp。)。

According to analysis of salt tolerance indexes, it was obtained that salt inhibited seed germination and seedling growth along with the increase of salt concentration, the relative germination rate, germination index and relative simple activity index, seedling root length and plant height reduced gradually, membrane permeability of leaves increased.

结果表明，盐胁迫对燕麦种子萌发和幼苗的生长有抑制效应，而且随着盐浓度的增加，相对发芽率、发芽指数、简易活力指数、幼苗根长和株高逐渐降低，叶片质膜透性逐渐增加。

They although cut went out to go up sinuately hill alley, but on the road if encounter an a Qing Teng, oak that prick a leaf, or one individual plant is called intimately by them the plant of the smoke tree and so on of " daughter red ", their would rather lowers his head to bow, sideways detour and over-, the life that also wants these green gives way, do not make they suffer any kill cut down and trample.

他们虽然开凿出了弯弯曲曲的上山小路，但路上假如遇见一根青藤、一棵刺叶栎，或者一株被他们亲昵地称为"女儿红"的黄栌之类的植物，他们宁肯低头弯腰、侧身绕路而过，也要给这些绿色的生命让路，不使它们遭到任何戕伐和践踏。
