栽培洋葱过程中,用正常发酵产气沼气池的沼液和水对返青后洋葱进行喷施试验。试验分别设喷施沼液1次组、2次组、3次组、4次组和喷施水对照组,每组3次重复,每组面积相同。喷施的沼液需加水,沼液∶水=3∶7。结果几组洋葱的霜霉病病情指数依次为:52,49,47,42和58;紫斑病病情指数依

During the cultivation of onions, the onions were sprayed with the biogas slurry and water from the normal fermentation biogas digester. In the experiment, the first group, the second group, the third group, the fourth group and the spraying water control group were respectively set up with spraying biogas slurry, and each group was repeated 3 times with the same area in each group. Biogas sprayed with water, biogas slurry: water = 3: 7. Results The disease index of downy mildew in several groups of onion was 52, 49, 47, 42 and 58, respectively;
