溶液培养是作物营养生理研究中的一种重要手段。但在连作晚稻生育初期,正值梅雨季节,培养过程中极易遭受霉菌的污染。去年入秋前,气候反常,长期高温阴雨,甚至在水稻生育中,后期也出现了污染情况,严重影响试验工作的开展。为控制霉菌的生长,我们将杀菌剂托布津添加在培养液中,取得了较为明显的效果。 Solution culture is an important method in crop nutrition physiology. However, even in the early stages of late rice growth, is the rainy season, the cultivation process susceptible to mold pollution. Last autumn before entering the autumn, the climate anomalies, long-term high temperature and rainy weather, even in rice growth, the latter also appeared in the pollution situation, seriously affecting the test work. In order to control the growth of the mold, we added the fungicide Topazin in the culture medium and achieved the obvious effect.
