| 摘 要： | 通过对渭北中部永寿县自然条件下小麦灌浆速度的实测,模拟得出了渭北小麦灌浆速度呈现单峰特征;干旱年灌浆速度增长快,一般正常年灌浆期长、千粒重大;渭北灌浆期干旱的主要影响是灌浆期时长。揭示了渭北小麦灌浆速度规律及其干旱的胁迫效应,为促进渭北小麦稳产提供了依据。

| Abstract: | Through the actual measurement of wheat grouting speed under natural conditions in Yongshou County which is in the middle of north Weihe River,the conclusions have been obtained through simulation that the growing speed of wheat in north Weihe River present the single peak characteristic;the growing speed is quicker during drought year,the time is longer and the 1000-grain weight is much weightier during general year.The major effect of arid in the period of grain filling in north Weihe River is the time of grain filling.It reveals the north Weihe River wheat grouting speed rule and drought stressing effect and provides some basis to promote the wheat a stable yield in north Weihe River. |
