论文部分内容阅读
前言最近阅读了大寨大队“三结合”科研组发表的《从大寨改土的实践看土壤学理论的发展》一文,其中“对土壤学中几个理论观点的评论”,反映了我国劳动人民,特别是无产阶级文化大革命以来,在伟大领袖毛主席革命路线指引下,对农业生产和相应的科学理论所取得的丰硕成果,深表赞同。现就“人的生产劳动是耕作土壤肥力发展的决定因素”和“从土壤整体构造上研究土壤肥力”两个方面,根据向贫下中农和有关部门学习所得,做些补充说明,试作引伸论证。由于认识水平所限,错误不免,希予指正。
Preface Recently, I read a paper titled “Development of Theory of Soil Science from the Practice of Soil Improvement in Dazhai” published by the “Three Combined” Research Group of Dazhai Brigade, in which “Comments on Several Theoretical Views in Soil Science” Since the Great Proletarian Cultural Revolution, the people, especially the Great Leap Forward, under the guidance of Chairman Mao’s revolutionary line, have allotted the fruitful results of agricultural production and corresponding scientific theories. Now on the “human productive labor is the decisive factor in the development of soil fertility farming” and “from the overall structure of the soil on the study of soil fertility,” two aspects, according to the poor middle peasants and the relevant departments to learn from income, to do some supplementary explanation, test extension argument . Due to the limited level of understanding, mistakes inevitably, I hope to correct.
