研究表明,宜春市番茄青枯病抑病土壤(白泥土)作用的主导因素是该类土壤碳酸钙含量高和土壤pH值偏碱,同时,与该类土壤粘腻以及对番茄青枯病的田间蔓延的阻抑作用也有密切的关系,而与土壤中其他微生物无关。研究还表明,白泥土和碳酸钙能抑制番茄青枯病菌及诱导番茄抗青枯病。
The results showed that the dominant factors of tomato bacterial wilt disease soil (white soil) in Yichun City were the high content of calcium carbonate in soil and the low pH value of soil, The suppression of field spread is also closely related, but not with other microorganisms in the soil. The study also showed that clay and calcium carbonate can inhibit tomato bacterial wilt and tomato resistance to bacterial wilt.
