Observed the influences of changing organic load on main microbe, the results showed that high load can cause the nematode mass rearing, made the sludge abnormal and the effluent quality bad. Branched zoogloea possesses stronger tolerance for water quality and shock loading, so did not change.

四，人为的改变有机负荷，观察其对于主体微生物的影响，结果表明高负荷容易引起线虫的大量繁殖，使得污泥发生异常，出水水质差，而主体微生物枝状菌胶团对冲击负荷的耐受力较强，并未发生明显改变。

RDNA-ITS sequence analysis of 30 populations showed that there is difference among M. incognita, M. hapla, M. arenaria, M. javanica, M. panyuensis, M. zhanjiangensis. and M. hainansis, whereas little rDNA-ITS sequence difference among three normal Meloidogyne species.

通过对30个种群的rDNA-ITS序列分析，发现番禺根结线虫、海南根结线虫、北方根结线虫、湛江根结线虫、南方根结线虫、爪哇根结线虫和花生根结线虫种间的DNA-ITS区碱基序列存在差异，但后3种常见种之间差异小。

First, according to the life cycle, epidemiology of major parasites, biologic characteristic of middle host and autochthonic weather, the periodical monitorial procedure was established, including the parasites were inspected in February, May, August and November every year, respectively.

采用粪便寄生虫虫卵检测和虫体鉴定方法调查四川凉山半细毛羊原种场及周围的羊寄生虫，主要有血矛线虫、奥斯特线虫、仰口线虫、夏伯特线虫、食道口线虫、毛首线虫、肺线虫、细颈线虫、片形吸虫、前后盘吸虫。

Previously, the strain K14 was screened with strong nematocidal activity, and a new water soluble nematocidal compound 2, 4, 6-triacetylenic octane diacid was isolated from the fermentation broth of K14 in this work. It is the first report that polyalkyne compound had nematocidal activity.

前期工作中筛选到一株对线虫活性强的食线虫菌物K14，我们对其产生的杀线虫活性化合物进行了进一步活性追踪分离，从其发酵液中分离到一个具杀线虫活性的新化合物2，4，6-三炔辛二酸，为水溶性成分，是首次报道多炔类化合物具有杀线虫作用。

The 111076 nematode individuls were classified into 43 genera and 4 trophic groups. Among them, 32 genera of nematodes belong to beneficial un-plant parasitic (bacterivorous, fungivorous, omnivorous/predatory) nematodes and 11 genera of nematodes belong to baneful phytophagous nematodes which accounted for 1/4 of nematode collectivity, especially the nematodes in the genus of Tylenchus and Filenchus, involved 51 (91%) and 42 (75%) species of flowers, repectively.

经鉴定111076条线虫分属43个属，4个营养类群（食细菌、食真菌、杂食/捕食和植物寄生线虫），其中有益的非植物线虫属32个，有害的植物线虫属11个，占总调查属数量的1/4，相对比例较大，特别是垫刃属和丝尾垫刃属的线虫出现的频率较高，涉及花卉51种和42种，分别占调查花卉总数的91％和75％。

The individual density was 4.77 inds. per gram dry soil. The results indicated that the number of soil nematode fluctuated significantly with season, the number of soil nematode in autumn is significantly more than that in summer and in spring. Shannon-Wiener index, Pielou index, Margalef index and Trophic diversity index were used in analyzing the diversity of nematode community, ranking Cc＞Pm＞Clc, while Simpson index ranking Pm＞Clc＞Cc. The value of f/b, MI index, PPI index, MMI index, MI2-5 index, SI index and EI index were used in analyzing the characteristics of the functional structure of the nematode communities, ranking Cc＞Pm＞Clc, while PPI/MI value ranking Clc＞Pm＞Cc. It showed that the Clc was disturbed significantly.

研究结果表明，土壤线虫数量存在明显的季节波动，秋季明显高于夏季和春季；土壤线虫群落多样性指数、均匀度指数、丰富度指数和营养类群指数大小依次为阔叶林、针叶林和混交林，而优势度指数却表现为：针叶林＞混交林＞阔叶林；土壤线虫群落营养类群f/b值、MI 指数、PPI 指数、MMI指数、MI2-5指数、SI指数和EI指数均表现为：阔叶林＞针叶林＞混交林，而PPI/MI指数则表现为：混交林＞针叶林＞阔叶林，表明混交林受干扰明显；土壤理化特征与线虫数量、属数、生态指数间也存在明显相关关系。

The effects of bur cucumber as rootstock on the mass of the first fruit, the number of female flowers on the main stem in 20 nodes, plant height, area of the biggest leaf, number of leaves, stem diameter, number of nodes were in the middle of the effects of black seed pumpkin as rootstock and self-rooted cucumber.

结果表明，棘瓜嫁接可使'中农21号'黄瓜的第1雌花开放期和始收期提前，对根瓜质量、20节内的雌花数、株高、最大叶面积、叶片数、茎粗和节数的影响小于'黑籽南瓜'嫁接处理；前者的抗寒能力、净光合速率强于后者和自根苗；棘瓜嫁接对黄瓜具有增产、抗枯萎病、抗根结线虫的作用，并且果实品质显著优于以黑籽南瓜嫁接的。

Only Ciliates had a clear peak of species number (28 species) among soil ...

4气温和地表温度对群落变化的影响较小：对线虫的种数变化有显著负相关；对原生动物、大中型土壤动物种数变化也只有阶段性的相关。
