在院工宣队革委会正确领导下,在贫下中农教师的具体指导下,1971年我们在一亩二分地的棉花丰产试验田里获得了亩产皮棉302.2斤的好收成,创造了狮子山上棉花单产的最高记录。这是毛主席教育革命路线的伟大胜利,是教学,科研、生产三结合新体制结出的丰硕成果。试验田土质为面黄土,中壤偏轻,肥力中等偏上,土层较深厚,地势高燥。前作萝卜,71年元月份收获,收后至棉花移栽前,先后进行了五犁四耙一耖,拖拉机耕深1.1尺,结合深耕全层深施底肥每田土渣肥12500斤,豆饼95.3斤,过磷酸钙119斤,做到了田平、土细、底肥足,为棉花全生育期的健壮生长发育准备了良好的条件。试验田所用品
Under the correct leadership of the Academy Brigade and Revolutionary Committee of the Academy of Engineering and under the specific guidance of poor and under-trained middle school teachers, in 1971 we obtained a good harvest of 302.2 kg of lint per mu of cotton yield in a two-acre yield experiment field and created a good harvest of cotton on Lion Rock The highest record of yield. This is a great accomplishment made by Chairman Mao’s educational revolution and the fruitful result of integrating the three systems of teaching, scientific research and production. Experimental soil loess surface, medium light soil partial, medium fertility, soil depth, high terrain. Before the turnip, harvest in January 71, after harvest to cotton before transplanting, has carried out a five-harrow a rake, tractor plowing 1.1 feet deep, combined with deep plowing the entire depth of deep-seated fertilizer per mu of soil 12,500 kg, 95.3 pounds of bean cake , 119 kilograms of superphosphate, so Tianping, soil fine, at the end of foot enough for the healthy growth and development of cotton throughout the growth period prepared a good condition.
