The surface activity of Hibiscus syriacus has been studied and shows thatHibiscus syriacus has good surface activity.The influence of temperature,saltness,water hardness and pH on the surface activity of its aqueous solutionsis also studied and shows little influnce.Also the mixture systems of Hibiscussyriacus with some anioic surfactants have been studied and the results show thatthe mixture systems can produce remarkable synergism.

天然表面活性植物木槿叶的应用研究本课题对天然植物原料木槿叶提取物中的表面活性物的性质(临界胶束浓度、表面张力和起泡性能)及其影响因素(温度、pH、水硬度和盐度等)进行了系统的研究，结果表明木槿叶表面活性物具有较好的表面活性，且它的cmc和〓在一定范围内受一些因素的影响也不大，是一种理想的香波原料；同时也研究了木槿叶活性物与其它温和型的阴离子表面活性剂的复配体系，表明具有明显的协同增效效果。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

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。
