我所早在1959年就曾进行过不同浸种方法的比较试验,以找出代替石灰水浸种的方法。结果发现,草灰水(指稻草灰水)浸种防病效果好。例如对稻瘟病防治效果:清水对照发病率33.5%;1%石灰水和5%草灰水浸种的,发病率都为12%,防效66.2%;10%草灰水浸种的发病率7%,防效80.3%。用5%和10%草灰水浸种的,相当或 As early as 1959, I conducted comparative experiments on different soaking methods to find a way to replace soaking lime water. The results showed that straw gray water (straw gray water) soaking disease prevention effect. For example, the control effect on rice blast was 33.5% in the control of clear water; the soaking rate was 12% and 66.2% in 1% lime water and 5% grass gray water; the incidence of 10% Effective 80.3%. Soaked with 5% and 10% grass gray water, equivalent or
