1961年到1962年调查总结了农民固有的淹稗经验,并进行了淹稗试验。试验引用了生产中较有成效的四种淹稗方法(即红光法、砂沟法、长兴法、太阳法),并在红光法的基础上加入晒田环节的综合法等五种方法(处理见表)。此外,为研究水温对灭稗效果 From 1961 to 1962, the survey summed up the peasants’ inherent experience of flooding barnyardgrass and carried out the flooding barnyardgrass experiment. The experiment cites five methods of flooding barnyardgrass (ie, red light method, sand gully method, Changxing method and solar method) which are more effective in production and five methods of integrating sunning field on the basis of red light method (See the table). In addition, to study the water temperature on the barnyardown effect
