浅谈秋季造林技术

兴隆林业局现有高山、石塘等造林困难地块2万亩，这些困难地块的特点是山高坡陡气温低，解冻晚，6月上旬积雪才能化净，而此时圃地草木已萌动放叶，造林后。难成活成林。     

超临界CO2萃取汽相色谱-质谱联用分析糯米香茶中的挥发油

采用超临界CO2萃取糯米香茶（Teucrium manghuaense）叶片的挥发性成分，经毛细管气相色谱-质谱联用仪（GC—MS）分析，鉴定其中的43种挥发性化合物，用气相色谱峰面积归一法测定各组分的相对百分含量。结果表明，其主要成分为角鲨烯（39．4％）、亚麻酸（20．5％）、丁香酚（14．7％）、叶绿醇（7．89％）、棕榈酸（4．81％）、γ-衣兰油烯（3．36％）和4-（4，5-二甲基苯基）-哌啶（1．29％）等。本研究旨在为进一步开发利用糯米香茶资源提供科学依据。     

细角螺的繁殖生态条件及繁殖习性

Hemifusus ternatanus(Gmelin), a gastropoda living in the deep water areas of undertide,as well as a delicious seafood, was distributed mainly in Chinese southeast seas and Japanese seas near the coast. In this experiment Hemifusus ternatanus' breeding ecological conditions and its propagation habit were studied in order to provide an experimental foundation for the artificial breeding. The brood stocks of test animals collected from the waters in Taiwan Strait, and then were examinated their growing temperature， salinity, feeding and propagation habit in the laboratory. The re sults showed that the growing temperature for Hemifusus ternatanus ranges from 16 ℃ to 32 ℃, with an optimum temperature between 20 ℃ to 28 ℃ and between 23 ℃ and 28 ℃ for breeding. The optimum growth salinity was 18.3-32.3 though it much adapts to salinity from 13 to 35. They prefer to feed on bivalves particularly those with thin shells and byssusless. Hemifusus ternatanus is dioecious and fertilization finishes inside the body. It was called as egg vesicle procreation that the whole stages of embryo growth were developed within egg vesicle. Larva forms as soon as it leaves egg vesicle, which is called direct occurrence type. The larva became the juvenile after metamorphosis during 20-25 days development. It was first to obtained 233 juveniles with shell height 32-45 mm by an artificial breeding method.     

取食番茄、辣椒和人工饲料对斜纹夜蛾生长发育和繁殖力的影响

分别用番茄果实、辣椒果实和人工饲料饲养斜纹夜蛾,观察不同食料对斜纹夜蛾(Spodoptera litura Fabricius)的生长发育、存活、不同龄期幼虫的粪便重量、成虫产卵量的影响,组建相应食料下的斜纹夜蛾实验种群生命表.结果表明:喂饲辣椒果实的斜纹夜蛾幼虫发育历期和全世代显著长于喂饲番茄和人工饲料,喂饲人工饲料的斜纹夜蛾不同龄期幼虫的粪便重量显著重于喂饲辣椒果实;种群趋势指数(Ⅰ)均大于1, 内禀增长力(rm)均大于0,斜纹夜蛾种群呈增长趋势.     

鹌鹑致病性大肠杆菌分离鉴定及抗生素敏感性试验

为确诊四川某养殖场产蛋鹌鹑死亡的病因,本试验采集病死鹌鹑的肝脏、心血等组织分离纯化细菌,并进行了细菌形态观察、生化特性检查、16S r RNA分子鉴定以及药物敏感性试验。结果显示:从肝脏、心血等组织中分离的细菌为致病性大肠杆菌;分离菌对环丙沙星、阿米卡星、大观霉素、链霉素、庆大霉素、头孢噻肟的敏感率均在84%以上,对氨苄西林、卡那霉素耐药。
