遵照伟大领袖毛主席关于“备战、备荒、为人民”和“必须把粮食抓紧”的教导,我们在1973年试制出74-1号叶肥,并开始进行肥效试验。1974年与河北省邯郸市轻化局化工研究所协作,研究出各种不同类型的叶肥,并在河北邯郸、张家口、石家庄、保定等地以及我校教学基点和农场进行田间肥效试验。1975年5月,在河北省科委和邯郸地、市科委的领导下,又在邯郸市召开了叶肥的鉴定会议,广大贫下中农、科研单位和农业院校报告了试验结果,并在各县、社、队组织生产,进一步在大田作物、果树、蔬菜及药用植物上进行试验。 Following the teachings of Chairman Mao, the great leader, on “preparing for war, preparing for famine, for the people,” and “grasping the grain must be tight,” we tested the leaf fertilizer 74-1 in 1973 and started the fertilizer test. In 1974, with Handan City, Hebei Province Bureau of Chemical Industry Institute of Light Chemical collaboration, developed a variety of leaf fertilizer, and in Handan, Hebei, Zhangjiakou, Shijiazhuang, Baoding and other places and our school teaching base and field fertilizer test. May 1975, in Hebei Province Science and Technology Commission and Handan, Municipal Science and Technology Commission under the leadership of another held in Handan City appraisal conference leaves fertilizer, the vast majority of poor and middle peasants, research institutes and agricultural colleges reported the results of the experiment, and in The counties, communities and teams organized their production and further experimented on field crops, fruit trees, vegetables and medicinal plants.
