基质对马铃薯疮痂病抑制效果研究初报

A STUDY ON CONTROL OVER STREPTOMYCES SCABIESOF VIRUS-FREE MICROTUBER WITH SUBSTRATUM

通过不同营养基质对马铃薯脱毒微型小薯疮痂病的抑制效果 ,从环境角度研究筛选防治疮痂病的新基质配比 ,首次提出利用工业废渣糠醛防治疮痂病的思路。结果表明 :采用蛭石 4∶火山石 1∶火炉渣 1∶草木灰 1∶糠醛渣 1的新配比基质 ,可有效抑制脱毒微型小薯疮痴病的发生 ,同时增加了基质的营养 ,所生产的微型小薯商品薯率也有明显提高 。

A new substratum formula,which can be used to control Streptomyces scabies of virus free microtubers,has been worked out through different controlling effectiveness against the disease caused by different nutritious substratum.The paper puts forard the idea of controlling S.scabies with furfural residue.The new substratum proportion is vermiculit 4:peat soil 1:slag 1:plant ash 1:farfural residue 1.The test result showed that the new substratum formula can effectively control the occurrence of S.scabies of virus free microtubers,and meanwhile increase nutrition of the substratum.The marketable rate of microtubers produced in this substratum was apparently high and the production cost was reduced.
