不同遮荫强度对几种苗木生长的影响

以黄金榕、花斑垂叶榕、乳斑榕的苗木为试验材料，来探讨不同遮荫强度苗木生长、水份利用及苗木生长环境的影响，试验表明：一层遮荫网处理的苗木比无遮荫网和二层遮荫网处理的苗木在株高、冠幅、根径以及叶片数目等方面均增长较快，苗木的地下部分、叶和茎含水量均较低。无遮荫处理利用较多水分，以及土壤温度在14：00点左右的时间明显高于所有的遮荫处理。     

关于我国海水网箱养鱼发展现状与危机分析及可持续发展的探讨

我国海水网箱养鱼发展现状是以个体联合体生产经营为主体的低技术水平的数量规模化，众多传统港湾已形成了大范围的严重超负荷养殖状态，其对环境巨大的污染力引发鱼病猖獗和频受赤潮侵袭，已面临严峻的养殖环境危机。本文综合分析了我国海水网箱养鱼的发展现状与负面效应及其现状危机，并初步进行了危机根源和可持续发展的讨论分析。

High frequency embryogenic callus induction and plant regeneration from mature caryposis of big bluestem and little bluestem

Big bluestem (Andropogon gerardii Vitman) and little bluestem [Schizachyrium scoparium (Michaux) Nash.] are native to the North America and are important forage grasses and ornamental grasses. Both grasses are proposed as ideal biomass producers for cellulosic ethanol production. To apply genetic transformation, which is an important tool for incorporating desirable agronomic traits into plants to both species, however requires an efficient and reproducible regeneration protocol. We used mature caryopses from big and little bluestem as explants and tested the effect of various combinations of 2, 4-dichlorophenoxyacetic acid (2, 4-D) (1, 2, 3, 4 or 5 mg l⁻¹) and kinetin (KT) (0, 0.1 or 0.2 mg l⁻¹) on embryogenic callus induction with LS as the basal medium. The highest percentage of embryogenic calli induction occurred on medium containing 2, 4-D alone at 2 mg l⁻¹ for ‘Bison’ and on medium containing 4 mg l⁻¹ 2, 4-D alone for ‘Bonilla’ big bluestem. For little bluestem, the highest percentage of embryogenic callus induction occurred on medium containing 3 mg l⁻¹ 2, 4-D plus 0.1 mg l⁻¹ kinetin, suggesting that addition of KT is beneficial. Shoot regeneration took place on LS basal medium without any plant growth regulator for both species, although the addition of KT increased both regeneration frequency and the number of shoots produced per callus. Rooting of shoots reaching about 2 cm long occurred readily with or without α-naphthaleneacetic acid (NAA). Rooted plantlets were all successfully established in the soil.     

中日森林文化比较研究及启示

日本是一个森林大国，拥有着丰富的森林资源和森林文化，其教训和经验对中国乃至全世界的后工业化国家都有着很大的启发和借鉴意义。对日本的森林状况进行回顾和评价，从其森林思想中汲取精华，不断挖掘森林文化所蕴藏的丰富含义，恢复和弘扬森林文化，这对中国正在开展的生态文明建设以及解决环境问题都能提供思考和帮助。     

基于ProE的香蕉假茎切块还田机构的模拟仿真设计与可行性试验

根据香蕉假茎先分段再进行无支撑切块还田的工艺设计思想，设计了香蕉假茎切块还田机构。该机构采用多把圆盘锯齿刀背刀交错布置于2条旋转轴上的类似对辊式运动原理的切块方法，利用ProE设计软件模拟仿真出合适的刀盘组合，以最快最准确的速度来完成切块机构的设计制作，并对此机构进行可行性试验。结果表明，采用嘲盘锯齿刀背刀交错布置在2条传动轴上的类似对辊式运动原理的切块机理可以实现切块作业。     

影响番茄离体培养再生的主要因素探讨

以5个番茄品种的子叶和下胚轴为外植体,对无菌苗的生理状态、激素组合、激素浓度和基因型等影响组培效果的主要因素进行探讨,建立了番茄的高效离体培养再生体系。结果表明,下胚轴和子叶均得到了高达100%的出愈率和95%以上的分化率;最佳的品种是T431;最佳激素组合为ZT1.0mg·L-1和IAA1.0mg·L-1。     

Effects of Three Drugs on Membrane Metabolism Against Cysticerci cellulosae in vitro

To investigate the effects and mechanisms of the benzimidazole carbamate and benmidine drugs on Cysticerci cellulosae and choose effective drugs on Cysticerci cellulosae, the membrane metabolism of Cysticerci cellulosae in vitro was tested after three kinds of drugs which were used respectively. The indexes included the contents of lipids, the contents of SA and the changes of the membrane fluidity. The results showed that oxfendazole could inhibit the membrane metabolism of immature and mature Cysticerci cellulosae in vitro, and albendazole only inhibited the mature one, while thibendimidine neither acted on the immature nor mature one.
