遵照毛主席“破除迷信,解放思想”的教导,我所在1971年试用“920”颗粒剂混播大麦,增产显著。试验结果表明;没有用“920”颗粒剂混播的亩产489.8斤,用“920”颗粒剂混播,每亩用量为50毫克的亩产592.53斤,增产20.9%;每亩用量150毫克的亩产625.1斤,增产27.6%;每亩用量300毫克的亩产741.83斤,增产 Following Chairman Mao’s teachings of “breaking superstition and emancipating the mind”, I experimented with “920” granules in 1971 to mix barley and increase yield significantly. The results showed that 489.8 kg per mu was not mixed with “920” granules, and 592.53 kg per mu was used with “920” granules per mu, with an increase of 20.9% Mg per mu 625.1 kg, an increase of 27.6%; mu yield of 300 mg per mu 741.83 kg, increase production
