石灰抑制稻纹枯菌的效应及应用研究

稻纹枯菌是水稻主要病害稻纹枯病的病原菌 ,由于其寄主范围广 ,变异性强 ,目前常用生物和化学农药防治 ,但污染重 ,成本高。笔者着重研究了石灰对稻纹枯菌的抑制及防治效果。经 3年的应用研究 ,现已证实该方法可行 ,且经济、安全无污染 ,实用性较强。

Research on the Affection of Restraint of CaO in Controlling Pellicularia.sasakii(shirai)and its Application

It was very difficult to control Pellicularia. sasakii (shirai)in agricultural production because it had a lot of hosts and its capability of variation was very strong. The routinely methods of chemical pesticides or biological control were used now, but they can cause pollution and were very expensive.On the basis of Physic-chemical characteristic of CaO and physiological property of Pellicularia. sasakii (shirai) ,we found another method. It had advantages of rapidity, simplicity, inexpensive and non-pollution, which revealed its potential capacity for application to agricultural production.
