【摘要】 作者提出玉米在有节奏生长全过程中的“双S”动态模型。第一个“S”过程是从出苗到开花授粉阶段,这一过程主要是根、茎、叶以及花器的建成。第二个“S”过程是从开花授粉到籽粒成熟阶段,这一过程光合产物的积累主要用于籽粒的增重。作者认为:“双S”生长模型揭示了玉米生长的内在规律,有助于玉米栽培管理科学化。更多还原

【Abstract】 This paper suggests a "Double S" dynamical growth model of corn. The first "S" model describes the period from the emergence of seedlings to florescence and pollination, the main processes during which are the formation of roots, stems, leaves and floral organs. The second "S" model describes the period from florescence and pollination to the mature of seed, during which the accumulation of the product of photosynthesis results mainly in the growth of seed The "Double S" model of growth reveals the inherent law of the growth of corn This theory is of extreme importance in the guidance of planting management of corn更多还原
