| 摘 要： | 本文阐明了掖单13等3个品种在公顷产量13.7t～15.9t条件下,N、P、K在体内的浓度,分布、移动的动态变化规律;建立了N、P、K吸收动态数学模型;查明了N、P、K吸收量、消耗系数、生产效率,不同生育阶段的吸收效量、速率、比例,最快吸收速率及其出现时间;分析计算了穗部和籽粒三要素的来源;明确了掖单13、掖单20、西玉3号春玉米品种在高产条件下N、P、K营养方面的共性与个性.

| Abstract: | In this paper,the changing law of N.P.K.consistency,distribution and movement in plant was expounded on CV.Yedan No.13 and other three varieties of 13.7-15.9t/hm 2 yield.The dynamic mathematical model of N.P.K.absorption was established.We made clear the absorption quantity,consumption coefficient and productivity of N.P.K.The quantity,speed and ratio of N.P.K.absorption during different stage,the fastest speed of absorption and its appearing time was made clear,too.We analyzed and computed the source of N.P.K.in seed and tassel.And the general character and individuality of N.P.K.nutrition was made clear on spring maize with CV.Yedan No.13 and No.20.and Xiyu No.3 under high-yield condition. |
