水稻干尖线虫病: 天津市双林农場自1955年以来即有水稻干尖线虫病發生。这是一种法定檢疫病害,其后逐濒蔓延,1957年感病率已达100%,减产高达12%,因此,稻谷产量有逐年下降趋势,严重的威胁着生产。为了杜絕病源,确保丰收,1958年我場痛下决心,全力以赴,将全場14万多斤稻种全部实行变温温湯浸种,徹底消灭了干尖綫虫病。一、使用的工具:这項作业无論在技术上和設 Rice dry tip nematodes: Shuanglin farms in Tianjin since 1955 that rice dry tip nematodes disease. This is a statutory quarantine disease, which then spread by the end of the line. In 1957, the prevalence rate reached 100% and the yield was reduced by as much as 12%. As a result, rice production has been declining year by year, seriously threatening the production. In order to put an end to the disease and ensure a good harvest, in 1958, I made painstaking efforts and went all out to soak up all the more than 140,000 kilos of rice seeds soaking in variable temperature warm soup that the dried tip nematodes were completely eliminated. First, the use of tools: This operation both in technology and design
