| 摘要: |
| 引言众所周知,粒重是构成冬小麦产量的三要素之一。因此,在穗数、粒数一定时,粒重的高低及波动可以代表一地的产量特征。从广义的库源学说来讲,籽粒是光合产物的库(sink),叶片是产生光合产物的源(Source),而茎、根则是传输系统1[1]。研究与实践表明:冬小麦最终产量是库对源的积 |

| Abstract: |
| On the basis of observation on the daily milk-filling speed of wi- nter wheat in Beijing area,mathematical simulations of the milk-fill- ing process there were made through the use of computers,and some information about the influence of weather fac ors on milk-filling and seedweight Was obtained.The practical importance the results had on agricultural production was studied and analysed.The results that this paper demonstrates may help provide agricultural weather data for raising the yield of winter wheat... |
