一、抑病土壤的发现和定义: 早年植病学家发现某些植物病害在不同田里发生轻重不同,报道最多的有小麦全蚀病和多种作物的镰刀枯萎病。1899年Atkinson发现美国Alabama州棉枯萎病在沙质土壤中重,粘质土壤中轻;1917年澳大利亚Perkins报道小麦全蚀病在新垦地上连作25年后病害消失。 First, the discovery and definition of disease-inhibiting soil: Early plantologists found that some plant diseases in different fields have different severity, the most reported wheat eclipse and a variety of crops sickle Fusarium wilt. In 1899, Atkinson found that cotton blight in the state of Alabama in the United States was heavier in sandy soil and lighter in clayey soils. In 1917, Perkins reported that the eclipse of wheat was lost after 25 years of continuous cropping on newly reclaimed land.
