Abstract:在盆载条件下,采用严重缺硼和轻度缺硼的两种土壤,研究了棉花硼氮营养的相互关系及其对棉花生长发育、产量品质的影响。三年研究结果表明:在两种土壤上,均以B(1ppm)×N(300ppm)配合施用,棉花产量最高,纤维品质最优,硼氮互作效应极显著。在两种土壤上单施氮肥均使缺硼症状加重,高硼时,适量增施氮肥使硼中毒症状减轻。在苗期,棉株体内硼的含量和单株吸硼量均因施氮而提高,现蕾后,单株吸硼量仍随施氮而提高,但植株组织中硼的含量却因施氮而降低。在严重缺硼的条件下,施硼显著地促进了氮的吸收和蛋白质的合成,而在轻度缺硼的条件下,施硼对氨的吸收影响不显著,但仍在一定程度上影响着游离氨基酸的含量。

Abstract:用a-(4-氯苯基)异戊酸和有机磷农药中的杂环醇(或酚)合成的非环丙烷类型的拟除虫菊酯的14个品种,对桃蚜、棉带卷叶蛾和柑桔红蜘蛛进行了毒力试验。结果表明,编号Ⅲ、Ⅵ、Ⅶ、Ⅹ、Ⅺ、ⅩⅦ和ⅩⅧ7个品种对桃蚜有良好的效果,死亡率均在80%以上。编号Ⅲ、Ⅵ、Ⅶ3个品种不但对桃蚜,棉褐带卷叶蛾有良好的毒效,对红蜘蛛也表现了相当的毒力,是许多拟除虫菊酯品种所没有的。它们的效果不低于高效有机磷的毒力。而且对人没有难闻的气味和刺激性。

Abstract:本文运用经典的房室分析法进行磺胺嘧啶对15只鸡静注、内服单剂量(0.2g/kg)和多剂量动力学研究,应用重氮化一偶合比色法测定血药浓度。试验除指出静注、内服的药时曲线符合无吸收二室开放模型和有吸收一室开放模型外,还对主要特征参数作了统计和表述。最后根据试验结果及药效学资料拟定的鸡连续静注、内服磺胺嘧啶钠的方案。
