        玉米栽培要點

         

        栽培要點 

        1、選用抗病親本(制種)或品種,積極引進高產、抗病的新品種。

         

        2、地膜覆蓋,適期早播,采用地膜全覆蓋或半覆蓋、適期早播可使玉米提早成熟,降低感病品種的穗軸和籽粒含水量,能有效減輕收獲和貯存期的病菌感染。

         

        3、及時剝掉 苞葉,防雨淋濕受潮。在剝苞葉過程中,對發現有病的果穗,應在發病與健康交接部位折去霉爛的頂端,防止病害進一步擴展,增加損失。

         

        4、早脫粒,防霉變,收獲后將病果穗挑檢出,盡早脫粒,并在日光下晾曬或在土坑上烘干,以防籽粒進一步受病菌感染霉爛。

         

        5、種子精選包衣,因玉米種子表面病菌存活時間1a以上 ,要對種子進行精選,剔除秕小病籽,用藥物種衣劑包衣。

        6、化學藥劑防治
