池塘底泥营养盐释放的室内模拟研究(英文)

[Objective] The study aimed to research the nutrients release of ponds sediment.[Method] The sediments which from a new pond(A) and an old one (B) these analyses used to carry out indoor experiment under the anaerobic dark condition for researching on nutrient release. The N(nitrogenous) and P(phosphorous) release were analyzed every two days.[Result] At the prophase, the N release in B was bigger than that in A, while the decline sediment release in A was gentle.[Conclusion] There was no accumulation of organic compound during the breeding time. The NH4-N was the main form of N release; and the P release was correlated with N release, while PO4-P was the main form of P release.     

World Association for the Advancement of Veterinary Parasitology (W.A.A.V.P.) guidelines for evaluating the efficacy of acaricides against (mange and itch) mites on ruminants

These guidelines have been prepared to assist in the planning, conduct and interpretation of studies for the assessment of the efficacy of acaricides against mange and itch mites on ruminants. Information is provided on the selection of animals, dose determination, dose confirmation and field studies, record keeping and result interpretation. These guidelines also are intended to assist the investigators on how to conduct specific experiments, to provide specific information for registration authorities involved in the decision-making process, to assist in the approval and registration of new ectoparasiticides, and to facilitate the worldwide adoption of standard procedures.     

短稳杆菌100亿孢子／毫升悬浮剂防治甘蓝小菜蛾毒力测定和田间试验

短稳杆菌（Empedobacterbrevis）是从罹病死亡的四龄斜纹夜蛾幼虫尸体中分离、筛选、纯化而来的生物农药创制新品种。经初步试验,该农药对鳞翅目害虫有较好的防效。为摸清进一步提高该农药防治甘蓝小菜蛾药效的有效途径,探索光照、温度、湿度、稀释浓度、防治对象不同虫龄与防治效果之间的关系,设置室内和田间药效试验,探析田间应用技术,为合理、科学、大面积推广使用该农药提供科学依据。     

牛不同生长发育时期卵泡AKP酶与G-6-P酶的活性变化

用组织化学方法观察了AKP酶(碱性磷酸酶)和G-6-P酶(葡萄糖-6-磷酸酶)在牛各生长发育时期卵泡的活性变化.结果表明:不同发育时期的卵泡数量与AKP酶和G-6-P酶活性反应阳性之关系极为显著,其中有腔卵泡的酶活性反应显示之数量多于腔前卵泡;但G-6-P酶活性反应之阴性卵泡显著多于阳性卵泡.AKP酶活性强于G-6-P酶.腔前卵泡酶活性位置显示之主要在颗粒细胞和卵母细胞上,而有腔卵泡酶活性位置则主要在内膜细胞上.
