The invention discloses a combination fertilizer and preparation method for preventing potato blight. The fertilizer consists of the following ingredients: azoxoxyl, phenoxazole, nitrogen, phosphate fertilizer, potassium fertilizer, humic acid, complexing agent, auxiliaries and trace elements. The preparation method is to grind nitrogen fertilizer, phosphate fertilizer, potash fertilizer, humic acid, humic acid, complexing agent and trace element into fine powder by sand mill according to the proportion of formula; the reaction kettle is added to the reaction kettle according to the formula proportion of dimethylene dimethoxazole and azoxoxyl ester, and the auxiliary reaction is added. The powder added to step 1 and step 2 is mixed evenly and added in the reactor. The water is filled with suspended liquid and the finished product. The invention has a unique bactericidal mechanism, the formation of protective film on the surface of the crop and the killing of the bacteria in the membrane, the long duration, the epidemic disease caused by fungi and bacteria, the comprehensive preventive and therapeutic effect of the virus disease, and the repeated spraying of germs will not produce resistance. The suspension dosage form is controlled by slow release technology, with long duration, high adhesion rate and good safety.

一种防治马铃薯疫病的组合药肥及制备方法
本专利技术涉及农作物疫病防治
,具体涉及一种防治马铃薯疫病的组合药肥及制备方法。
技术介绍
马铃薯属茄科多年生草本植物,块茎可供食用,是全球第三大重要的粮食作物,仅次于小麦和玉米,马铃薯在我国也被列入主食系列,也越来越被人们重视,种植规模和面积不断增加,深加工技术也方兴未艾,对马铃薯品质的要求也愈加严格,种植过程中,马铃薯疫病会造成大幅度减产。其疫病可发生在叶片上,也可浸染块茎,发病严重的叶片干枯脱落,田间植株成片枯黄,块茎染病产生暗褐色稍凹陷圆形或近圆形病斑,边缘分明,皮下呈浅褐色海绵状干腐,该病近年来呈上升趋势,其危害不亚于晚疫病,马铃薯疫病导致全株枯焦腐烂,极大地影响了马铃薯的品质和产量,也是种植马铃薯的农民最为担心的问题。
