山东省滨县1954年冬小麦虽已普遍丰收,但麦子穗头不大,(每穗平均重2分4厘)麦穗粒数不多(每穗粒数平均27.3粒),分(木义)少(分(木义)平均3个),因而使小麦更大丰收受到了限制,我们对如何促进小麦根部生长扩展的问题进行了摸索。今将处理方法及初步结果,介绍于下,以供各地参考;一、用过磷酸钙1斤,压成细粉,加水100斤,充分搅拌5分钟,放一夜后滤去渣子(或不滤去也行),然后放入小麦,再搅拌3分钟,浸1天,第二天捞出 Shandong Binxian 1954 winter wheat although the general bumper harvest, but the wheat spike is not large, (average weight per spike 2 points 4%) fewer grains per spike (grains per spike average 27.3), points (woody) Less (three points on average in Muyi), thus limiting the wheat harvest to a greater extent and exploring the issue of how to promote the growth and development of wheat roots. First, with superphosphate 1 kg, pressed into fine powder, add water 100 pounds, stir for 5 minutes, put the residue after filtering overnight (or not filtered Go okay), and then into the wheat, and then stirred for 3 minutes, soaked for 1 day, remove the next day
