我们在研究小麦不稔症时发现:在历年小麦不结粒的地段,大豆出苗后期常发生顶芽枯萎的现象,我们称之为“芽枯病”。其分布规律及面积和小麦不稔症的分布规律及面积很相似。据我们在某连调查,常年发生面积占播种面积的1/6以上。因此大豆产量一直很低,1974年产量最高,也不过亩产123.4斤,严重 When we studied the disease of wheat, we found that in the non-grain-bearing area of ​​wheat in the past years, the phenomenon of terminal bud wilt often occurs in the post-emergence stage of soybean, which we call “bud blight.” Its distribution and area and the distribution of non-hysteria and the area is very similar. According to our survey in a certain company, the perennial area accounts for more than 1/6 of the sown area. Therefore, soybean production has been very low, the highest yield in 1974, but also yield 123.4 pounds per mu, serious
