近年来各地常用402、多菌灵、石灰水等药剂,进行水稻种子消毒,但从效果看,很多地方对种子传染性病害如稻瘟病、胡麻斑病、恶苗病,在育秧阶段发病为害仍十分严重。究其原因,不是402等药剂无效,而是和浸种时温度低、浸种时间短、药剂浓度小有关. 为了探求浸种温度、时间和浓度情况,对水稻种子发芽的影响,我们作了如下试验。 In recent years, commonly used 402, carbendazim, lime and other agents for rice seed disinfection, but from the effect of view, many places of seed infectious diseases such as rice blast, flamboyant spot, Very serious. The reason is not 402 and other agents invalid, but with the soaking temperature, immersion time is short, the concentration of the agent is small.In order to explore the soaking temperature, time and concentration of rice seed germination, we made the following test.
