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 m3) 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/hm2 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.

使用有机开发的猪粪肥,使用抗性谷物纹枯病菌菌株控制小麦的锋利斑点。

研究了抗谷物纹枯病菌菌株对猪粪开发的有机肥中小麦尖锐眼斑的控制作用。有机肥料是在自建的充气静态堆肥箱(0.37立方米)中生产的,随后使用温度,湿度,pH,C / N比,氮转化率,氟-腐殖酸组成和发芽指数进行评估。综合起来,这些评估表明,处置的猪粪可以被认为是一种无害肥料。通过添加抗谷类芽孢杆菌的菌株(弯曲芽孢杆菌,解淀粉芽孢杆菌,解淀粉芽孢杆菌,地衣芽孢杆菌和Paenibacillus sp。),我们成功开发了抑制小麦尖锐斑点的生物有机肥料。我们的结果表明,施用10吨/ hm2的先进生物有机肥料的土壤显着提高了小麦的干重,促进了叶绿素和可溶性蛋白质的组成,并有效地防止了小麦出现明显的斑点。我们开发的生物有机肥料的保护率(77.1%)比经测试的市售有机肥料(34.8%)高42.3%,并且疾病指数显着低于对照和商业有机肥料(P <0.001) 。综上所述,我们开发的生物有机肥料对小麦尖眼斑的防治效果显着且很有希望。我们开发的生物有机肥料的1%)比经测试的市售有机肥料(34.8%)高42.3%,并且疾病指数显着低于对照和商业有机肥料(P <0.001)。综上所述,我们开发的生物有机肥料对小麦尖眼斑的防治效果显着且很有希望。我们开发的生物有机肥料的1%)比经测试的市售有机肥料(34.8%)高42.3%,并且疾病指数显着低于对照和商业有机肥料(P <0.001)。综上所述,我们开发的生物有机肥料对小麦尖眼斑的防治效果显着且很有希望。
