在中共中央“关于深耕和改良土壤的指示”和教育与生产劳动相结合的方针指示下,我们实习队自己做了小麦深翻地试验。目的是通过不同深度的翻耕与施肥措施,企图摸出小麦生长发育适宜的的翻耕深度与施肥方法;并给以科学分析研究,寻找理论根据。目前生长发育已进入三叶期。最近我们就此发育阶段的土壤含水量、空隙率、麦株根系发育及地上部分生长发育情况、植株干重、生长锥分化、地下虫害等方面假了初步小结。关于土壤化学性质及
Under the directive of the Central Committee of the Communist Party of China on “Guidelines on Deep Soil Improvement and Soil Improvement” and on the combination of education and productive labor, our internship team conducted a deep-rooted wheat experiment. The purpose is to find suitable tillage depth and fertilization methods for wheat growth and development through tillage and fertilization measures at different depths; and to give scientific analysis and research and find theoretical basis. The current growth and development has entered the clover period. In the recent developmental stages of soil moisture content, porosity, wheat root development and aboveground growth and development, plant dry weight, growth cone differentiation, underground pests and other aspects of the preliminary summary.
