【摘要】 在总结“麦无二旺”和蹲苗等农民经验的基础上,经过实验看出:小麦器官生长相互关系,器官生长与同化产物积累、消耗的相互关系对子粒和产量的形成起重要作用,肥水等栽培条件通过影响体内这些关系对产量发生影响。经过几年来在生产中检验,本实验所得的一些结论对控制植株旺长,增加粒数和粒重比较有效。更多还原

【Abstract】 Experiments have been carried out in Peking in 1962--1963 with 3 varieties of winter wheat: "A. U. 183", "Peking Ⅵ" and "B. M. Ⅰ". After they have turned green in the spring, they were treated with ammonium sulphate and watered at three different stages: Stage Ⅰ, March 20th; Stage Ⅱ, March 30th; Stage Ⅲ, April 18th. The purpose is to study the interrelationship between the plant growth, organ deve- lopment, the accumulation & distribution of dry matter and carbobydrates under different treatments, and to study the effect of their relation to the growth of ears and yields.更多还原
