沼液施入农田,不仅可以肥田,还能防治多种病害,亦可用来处理稻种,是一种不可多得的廉价农药。 一、浸种能防杂菌感染。用沼原液浸稻种48小时后,稻瘟病菌的感染率显著下降,其防病灭菌作用近于“401”液,高于石灰水灭菌效果。同时,用沼液浸种能提高稻谷的发芽率,与“401”处理作对照可高出三个百分点。 二、泼浇可防治稻纹枯病。在杂交晚稻上,在 Biogas slurry into the farmland, not only fertilizer, but also control a variety of diseases, can also be used to deal with rice, is a rare low-cost pesticides. A, soaking can prevent bacterial infection. Inoculation of biogas solution 48 hours later, the infection rate of Magnaporthe grisea decreased significantly, its anti-disease sterilization effect is near “401” liquid, higher than the lime water sterilization effect. In the meantime, soaking seeds with biogas slurry can increase the germination rate of rice, which can be increased by three percentage points compared with “401” treatment. Second, pouring water can prevent rice sheath blight. On the hybrid late rice, at
