由Xanthomonas campestris PV.oryzae引起的水稻白叶枯病,是威胁水稻高产、稳产的重要病害之一。由于缺乏高效低残毒农药,常因此病而造成稻产的严重损失。多年的生产实践证明,鉴定、选育抗病品种用于生产,是根本控制白叶枯病危害的经济有效措施。目前,我国水稻白叶枯病抗病育种所用抗源大多为外引籼型,而本研究则以地方粳稻品 Bacterial leaf blight caused by Xanthomonas campestris PV.oryzae is one of the most important diseases that threaten the high yield and stable yield of rice. Due to the lack of efficient and low residual pesticides, often caused by this disease caused serious losses of rice production. Years of production practice has proved that the identification and selection of resistant varieties for production are the economic and effective measures to fundamentally control the harm of bacterial leaf blight. At present, most of the resistances used for disease resistance breeding of rice bacterial blight in China are external indications, while in this study, local japonica rice

金银花的花蕾由黄变白时即要采收.辽南一般在6月10~20日采第一茬花,7月5~23日采第二茬花.过早过晚采收对质量都有影响.一天中最适的采收时间是上午露水干后(花蕾有露水不易干)
