小麦起身后期喷施不同浓度agrova可以促进小麦生长和增强小麦的抗病性。Agrova处理后小麦茎粗增加 0 .1～ 0 .2mm ,次生根平均增加 3～ 4.6条 ,小麦功能叶延迟衰退 2～ 4d。Agrova处理使小麦的小穗退化减少 ,结实率提高 ,千粒重增加 0 .6 2～ 1.94g ,小麦平均亩产增加 5 %～2 9%。处理后的小麦对小麦纹枯病有 2 4.5 6 %～ 6 9.5 9%的防治效果 In the late stage of wheat upgrowth, different concentrations of agrova can promote the growth of wheat and enhance the disease resistance of wheat. After the Agrova treatment, the stem diameter of wheat increased by 0.1 ~ 0.2mm, the average number of secondary roots increased by 3 ~ 4.6, and the delayed decline of functional leaves in wheat was 2-4 days. The Agrova treatment reduced the spikelet degeneration of wheat, the seed setting rate increased, the grain weight increased 0.626 ~ 1.94g, and the average yield of wheat increased 5% -29%. Treated wheat had control effects on wheat sheath blight from 4.56% to 6 9.59%
