在毛主席革命路线的指引下,去年我校高中化学、农业两科的教师,面向农业生产开门办学,开设土壤诊断专业课,受到贫下中农的欢迎,在农业生产上取得了一定的成绩。现将试验小结简报如下:试验田概况试验田选在余杭县石鸽公社沈家大队第八生产队,是该公社50％以上低产田的低丘陵红壤母质水稻土中具有代表性的一块田。早稻产量在300斤/亩左右,晚稻产量只有100～200斤 Under the guidance of Chairman Mao’s revolutionary line, last year, teachers from the two branches of chemistry and agriculture in our high school opened their doors to agricultural production and opened soil-based diagnostics courses. They were welcomed by poor middle peasants and made some achievements in agricultural production. The brief summary of the experiment is as follows: Summary of Experimental Fields The experimental field was selected as the eighth production team of the Shenjia Brigade of the Stone Pigeon Company in Yuhang County. It is a typical field in the red soil parent material paddy soil of more than 50% of the low-yielding fields of the commune. Early rice production in 300 kg / mu or so, late rice production is only 100 to 200 pounds
