The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

本文用&Y&形嗅觉仪法和培养皿法测试了山楂叶螨Tetranychus viennenis Zacher对不同植物气味物质的嗅觉反应，并利用固相微萃取SPME吸附、用气相色谱—质谱联用仪GC-MS(gas chromatograph-mass spectrometer)分析了不同植物叶片的挥发性物质成分：同时采用海绵水盘法饲养山楂叶螨，研究了不同植物对山楂叶螨生长发育的影响，并测定了不同植物叶片中一些生化物质的相对含量。

The major dominant species of predatory enemies were Erigonidium graminicola and Theridion octomaculatum and their individuals were 81.4 percent of the total predatory enemy individuals of the community.1.2 Spatial patterns and their dynamics of major dominant predatory enemies ofarthropod communityThe research results showed that Pieris rapae distributed mainly on heart leaves and back of inner leaves of cabbage plants, Plutella xylostella distributed mainly on the back of cabbage leaves and Lipaphis erysimi distributed widely in cabbage plants. Among the major dominant species of predatory enemies, Sitticus sinensis distributed mainly on the front of leaves of cabbage plants in spring cabbage fields, and Misumenopos tricuspidata and Propylaea japonica distributed widely in cabbage plants.

在捕食性天敌中蜘蛛10种，捕食性昆虫3种，主要优势种为草间小黑蛛、八斑球腹蛛，其数量占捕食性天敌总数量的81.4%。1.2节肢动物群落主要优势种的空间格局及其动态研究结果表明，害虫优势种菜青虫主要分布于甘蓝心叶和甘蓝叶反面，小菜蛾主要集中分布在甘蓝叶的反面，而菜蚜在甘蓝植株内的分布较广；春甘蓝田捕食性天敌优势种中华跃蛛在外层叶正面分布较集中，三突花蛛与瓢虫类在甘蓝植株内的分布较广。

Both the thermophilous plants and hardy plants should be planted to keep the operation of the wetland system all tear round and the submerged plants and the emerging plants should be planted in a same space to make the wetland system more effectively.

在时间上，可将喜温植物与耐寒植物结合，以保证湿地系统的长年运行；在空间上，可将挺水植物与沉水植物结合，以保证湿地系统的处理效果。

During the study period, we found that plants were present only in natural creek banks, but not altered ones. Comparisons between natural banks without plants and altered banks revealed no significant difference in both shrimp abundance and distribution. However, there was significant difference in shrimp abundance when natural banks with plants and altered banks were compared, suggesting that construction might have negative effects on plants and, in turm, on shrimp abudance. Comparisons between reproductive and non-reproductive season yielded significant results in both shrimp abundance and distribution, which resulted from the recruitment of juveniles to local populations.

在实验期间，自然河段有水蕴草而整治河段没有水蕴草的存在，比较无水蕴草的自然河段与整治河段，发现无论是数量或出现率都没有显著差异，然而，在有水蕴草存在的自然河段之多齿新米虾数量与出现率则较整治河段高，显示哈盆溪可能因为整治工程影响了底质的型态，导致水蕴草不易生长，进而影响多齿新米虾的数量及出现率；在季节方面，结果显示，不同季节在数量和出现率上都有显著差异，而此差异是因为幼虾在生殖季大量加入族群所致。

Disease-resistance test of the plants demonstrated that the grey-mildew tolerance ofthe transgenic plants, which varied with different transgenic plants, was strongerthan that of the untransformed plants.

The writer thinks existing major problems:1、The confusion Produces by the same plant have the different name、the different plant have the same name、think the typeface meaning just the righteousness,even fabricate without basis etc; 2、Because dont understand living creature type and adaptability in the depth of the water for the plants , A great deal of aquatic plants death;3、In planting design, so much express of plants specification ,and many of them are disobey with biology characteristic, so the plants are hard for purchase or the result is very bad after plant; 4、Plant density more than 100 times or less than several decuples of normal.

作者认为存在的主要问题有：1、植物名称同物异名、同名异物、望文成义，甚至凭空捏造等等产生的混乱；2、植物生物型和水深适应性不了解造成的种植水深不符植物习性，从而使大量水生植物死亡；3、种植设计中，苗木规格的表述不妥，许多表述与植物的生物学特性相违背，造成苗木难以采购或种植后效果极差；4、种植密度严重偏大或偏小，偏大的大于正常的100多倍，小的则少几十倍。
