通过大田和盆栽试验，筛选出四种对小麦雨后青枯逼熟有较强防御作用的化学制剂：SMZ-TMP、黄腐酸、磷酸二氢钾和粒重保。这几种制剂不仅可以防御青枯，而且可以促进小麦灌浆和增加粒重。其适宜浓度除SMZ-TMP为4mg／L外，其余都在1500～2500mm／L范围内。
Through field and pot experiments, four kinds of chemical agents were screened for their strong defensive action against wheat bran, such as SMZ-TMP, fulvic acid, potassium dihydrogen phosphate and grain weight. These preparations not only can prevent the chlorosis, but also can promote wheat grain filling and increase grain weight. The appropriate concentration except SMZ-TMP 4mg / L, the rest are in the 1500 ~ 2500mm / L range.
