The effects of Rhizoctonia cerealis resistant strains to control wheat sharp eyespot in pig manure developed organic fertilizer were investigated. Organic fertilizer was produced in a self-built aerated static composting box (0.37 m) and later assessed using values of temperature, moisture, pH, C/N ratio, nitrogen transformation, fluvic- and humic acid composition and germination index. Together, these assessments indicated that disposed pig manure could be considered as a non-hazardous fertilizer. By adding R. cerealis resistant strains (Bacillus flexus, B. amyloliquefaciens, B. amyloliquefaciens, B. licheniformis and Paenibacillus sp.), we were successfully able to develop wheat sharp eyespot inhibiting bio-organic fertilizer. Our results showed that soil applied with 10 t/hm of the developed bio-organic fertilizer significantly improved the dry weight of the wheat, promoted chlorophylls and soluble protein composition and effectively prevented the wheat from sharp eyespot. The protection rate (77.1%) of our developed bio-organic fertilizer is 42.3% higher than the tested commercially available organic fertilizer (34.8%), and the disease index is significantly lower (P < 0.001) than both the control and commercial organic fertilizer. In conclusion, the prevention and control effects of our developed bio-organic fertilizer on wheat sharp eyespot were both significant and promising.
研究了抗立枯丝核菌菌株对猪粪有机肥中小麦纹枯病的防治效果。有机肥在自建的充气静态堆肥箱（0.37 m）中生产，并通过温度、水分、pH 值、C/N 比、氮转化、黄腐酸和腐殖酸组成和发芽指数进行评估。这些评估表明，处理过的猪粪可以被认为是一种无害肥料。通过添加抗立枯丝核菌菌株（解淀粉芽孢杆菌、解淀粉芽孢杆菌、地衣芽孢杆菌和蜡样芽孢杆菌），我们成功地开发了抑制小麦纹枯病的生物有机肥料。研究结果表明，土壤施用 10 t/hm 的开发生物有机肥料显著提高了小麦的干重，促进了叶绿素和可溶性蛋白质的组成，有效地防止了小麦纹枯病的发生。与市售有机肥（34.8%）相比，我们开发的生物有机肥料的防治效果（77.1%）提高了 42.3%，病情指数显著低于对照和市售有机肥（P<0.001）。综上所述，我们开发的生物有机肥料对小麦纹枯病的防治效果显著且有前景。
