摘要
本文研究沼液防治小麦赤霉病的效果,并与对照和多菌灵进行比较,得出下列结论: 1.采用正常运行的沼气池生产的沼液防治小麦赤霉病发病率比对照下降20.71％,相对防治效果提高44.88％,与多菌灵防效相当。 2.沼液防治小麦赤霉病,以不稀释在小麦盛花期亩喷50公斤效果最好。 3.沼液防治小麦赤霉病,不需投资,便于推广,避免使用农药造成的环境污染。
The control of wheat gibberella disease by using biogas slarry studied during 1987-1990. 1. Using biogas slurry, produced from normal biogas plant, was controled wheat gibbe- rella disease. The incidence of wheat gibberella disease has decreased 20.71% as less as that of check. The control effectiveness of liquid biogas was same to carhendazim (Bavistin). 2. The non-dilute biogas slurry was applied 50kg per mu at wheat anthesis. It will be better that sprays were applied at early-and mid-anthesis. 3. Useng biogas slurry to control wheat gibberella disease was easy to extend and avoid pollution by using chemicals.
