Leaf age index

The earlier sowing was,the longer the male ear differentiation periods and the durationu from seeding stage to last milk stage were, but the duration of ear differentiationwas steady ; The corresponding reIationship between leaf age index and spike differentiati.

本文通過對鮮食玉米“津鮮1號”在3個播期下的生育進程及穗分化觀測研究，結果表明：津鮮1號玉米生育進程因播期不同而異，播期越早，雄穩分化時間以及從出苗到乳熟末期（采收期）所經歷的時間越長，而雌穗分化持續時間穩定；3個播期葉齡指數與穩分化時期對應關系穩定，且均符合一元二次函數關系。

研究得出,葉齡與穗分化時期的對應關系因品種、播期而異;葉齡余數與主要穗分化時期的關系在適播條件下品種間十分接近;葉齡指數與穗分化的關系因品種而異,但不同播期間差異較小。

The law of population size,urbanization degree and aged index in mid-long term are obtained.

針對我國城市化步伐加快、性別比持續升高等具體現狀,引入了女嬰比等參數,改進了以往的離散人口預測模型,得出了我國人口總量、老齡化指數等在中長期內的發展變化規律,預測結果合理,為相關部門制定人口政策提供了有益的數據支持。
