| 摘要: |
| 引言应用电子计算机对1973—1979年、北京地区23个样本组的冬小麦灌浆资料进行了数学模拟,得到了天气、气候因素对灌浆、粒重影响的若干信息。其中,有关天气影响的分析已作了报导[1]。本文仅就全生育期中的气候影响做探讨,以为提高冬小麦产量提供农业气候依据;同时,也为千粒重的农业气象予测寻求了途径。一、灌浆进程的模拟与气候信息方程的确定, |

| Abstract: |
| Mathematical simulations of the seed-filling process of winter wheat show that the annual change of one-thousand-grain weight is not only influenced by climate in the seed-filling period but interfered by early-stage climatic factors as well.This paper demonstrates that the filter-separation method was used and informations on climatic influence on the change of one-thousand-grain weight were obtained.The results may help provide agricultural climatic data for raising the yield of winter wheat as well as fi... |
