【摘要】 简要介绍了水绵的生物学特性及发生情况。室内初步研究了硫酸铜、三苯基醋酸锡及两者薯瘟锡混剂对水绵的生物活性。结果表明,三苯基醋酸锡对水绵的防除效果最好,在70ga.i./hm2剂量下对水绵的防效可达90%,其次是三苯基醋酸锡与硫酸铜混剂,再次是硫酸铜。更多还原

【Abstract】 Spirogyra communis biology character was introduced in the paper. Three chemicals bluestone, fentin- acetate, bluestone+fentin-acetate’s efficacy on Spirogyra communis was studied in greenhouse. The result showed that fentin-acetate had the best efficacy on Spirogyra communis, and then bluestone+fentin-acetate and bluestone.更多还原
