编辑同志:时下,在有些地区农村的水稻田,已出现纹枯病的迹象,加上当前气温还较高,湿度还较大,水稻纹枯病很有司能会继续蔓延。据了解,现在有些农户缺乏科学管理知识,对农药使用和保管也缺乏经验。为此,想借贵报一角,介绍这方面的知识,供农民参考。防治水稻纹枯病与农田科学管理和药物防治相结合进行。农田管理最要紧的是合理施肥和科学灌水。在水稻生长后期要严格控制氮肥施用量,增施磷钾肥,以防止水稻生长过旺,贪青晚熟。在灌水上,要坚持干干湿湿,防止满水灌溉。如发现病情,要适时喷药防治。水稻进入孕穗期发病,可用多菌灵喷治,药液要尽可能均匀 Editing Comrades: Nowadays, there are signs of sheath blight in paddy fields in rural areas in some areas. In addition, the current temperature is still high and the humidity is still relatively high. Therefore, there is a great risk that rice sheath blight will continue to spread. It is understood that some farmers now lack scientific management knowledge and have no experience in the use and custody of pesticides. For this reason, I would like to borrow a corner of your newspaper to introduce this knowledge for reference by peasants. Prevention and control of rice sheath blight and farmland scientific management and drug control combined. Farm management is the most important is the rational fertilization and scientific irrigation. In the late rice growth stage, we must strictly control the amount of nitrogen fertilizer, increase the phosphorus and potassium fertilizer to prevent over-growth of rice, greed green late. In irrigation, we must insist on wet and dry, to prevent water full of irrigation. If found disease, timely spraying prevention and treatment. The incidence of rice into the booting stage, available carbendazim spray, liquid should be as uniform as possible
