《四川农业科技》新辟《农广校学用园地》专栏时,正逢我省数逾十万的农广校第二届农学专业的学员《土壤肥料学》结业。作为农广校四川分校的辅导教师,特在这一园地讨论这一题目,主观意图是想帮助广大学员将所学的肥料学理论知识运用到农业生产实践中去,使施肥更加科学合理,不但增产更要增收。由于这是一个大题目,限于篇幅,不可能很全面充分的讨论,只能根据我省具体情况,提出一些粗浅建议。但愿本文的内容能对学员们有某种参考价值。合理施肥才能增产增收。在所有的农业增产措施中,据认为,十九世纪中后期西欧的农业飞跃和本世纪五十年代至今的全球性农业飞跃,约有50％是增施化肥和改进施肥技术的结果。要做到合理施肥,就必须用肥料学等有关学 When “Sichuan Agricultural Science and Technology” opened up a new column for “Agricultural University campus”, it coincided with the completion of “Soil and Fertilizer Science” course of the second agronomy major of Agricultural Science and Culture University with more than 100,000 in our province. As an adviser to ABC’s Sichuan branch, this special topic is discussed in this garden. The subjective intent is to help the majority of trainees to apply the theory of fertilizer science learned to agricultural production practice so as to make fertilization more scientific and reasonable. More production but also income. Since this is a big issue, due to space limitations, it is impossible to fully and fully discuss it, and we can only make some superficial suggestions based on the specific conditions in our province. I hope the contents of this article can have some reference value for the students. Rational fertilization in order to increase production and income. Of all the agricultural stimulation measures, it is believed that about 50% of the agrarian leaps in Western Europe in the mid- to late-nineteenth century and the global agricultural leaps from the 1950s to the present are the result of increased fertilization and improved fertilization techniques. To achieve reasonable fertilization, we must use fertilizers and other related studies
