The suppressive effects of soil bio-solarization, which is a new method of soil disinfestation that combines soil bio-fumigation with soil solarization, against the sclerotial viability of Stromatinia cepivora and the subsequent control of white rot disease of onion and garlic were evaluated. Soil was bio-fumigated with fresh amendments of cow manure, chicken manure, horse manure, cruciferous plant residues, or Allium waste, at 30,000 kg/ha. After bio-fumigation, the soil was irrigated and covered with a 200 μm transparent plastic sheet for 60 days. Plots that received fresh amendment and remained uncovered and untreated served as controls. Solarization alone increased the maximum soil temperature to 55.3 °C, 50.3 °C and 46.3 °C at 10, 20, and 30 cm depths, respectively, which led to significant reductions (98.0%, 89.3%, and 62.7%, respectively) in the sclerotial viability of S. cepivora. Soil bio-solarization with cruciferous plant residues or Allium waste resulted in the strongest negative effects on the sclerotial viability of S. cepivora, with reductions of 100.0%, 98.7%, and 87.3% or 100.0%, 99.3%, and 87.7%, at 10, 20, and 30 cm depths, respectively. Compared to the non-treated control, these treatments significantly reduced the incidence of white rot disease in onion and garlic, which led to increases in onion and garlic yield in fields that were heavily infested by S. cepivora.

土壤生物增溶法降低了头孢菌(Sromatinia cepivora)的菌核活力并控制了洋葱和大蒜的白腐病

评价了将土壤生物熏蒸与土壤日光化结合起来的一种新的土壤杀虫方法,即土壤生物增生抑制菌头孢菌Strromatinia cepivora)的菌核生存能力以及随后对洋葱和大蒜白腐病的防治效果。用牛粪,鸡粪,马粪,十字花科植物残留物或葱属的新鲜改良剂对土壤进行生物熏蒸废料,30,000公斤/公顷。生物熏蒸后,将土壤灌溉并用200μm透明塑料板覆盖60天。接受新修正并仍未发现和未处理的地块作为对照。仅靠日晒,在10、20和30厘米深度处,最高土壤温度分别升高到55.3°C,50.3°C和46.3°C,这导致土壤最大温度显着降低(分别为98.0%,89.3%和62.7%)。S的硬化能力。头孢属。用十字花科植物残留物或葱属废弃物对土壤进行生物固溶处理头孢链霉菌的菌生存力具有最强的负面影响,在10、20和30厘米深度处分别减少100.0%,98.7%和87.3%或100.0%,99.3%和87.7%。与未处理的对照相比,这些处理显着降低了洋葱和大蒜中白腐病的发生率,这导致了严重受塞氏链球菌感染的田间洋葱和大蒜产量的增加。
