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。 In this paper, the effect of biogas slurry in controlling wheat scab was studied and compared with the control and carbendazim. The conclusions are as follows: 1. The incidence of control of wheat scab in the biogas slurry produced by normal operation decreased by 20.71 %, The relative control effect increased 44.88%, and carbendazim control effect is quite. 2 biogas control of wheat scab, not diluted in full bloom wheat flour acres spray 50 kg best. 3. Biogas slurry control of wheat scab, without investment, easy to promote, to avoid the use of pesticides caused by environmental pollution.
