【摘要】 通过分析1995~2005年冬小麦灌浆期间的灌浆速率、千粒重及其与大气湿度、气温日较差等的关系发现:冬小麦在灌浆过程中灌浆速率、千粒重变化呈S型曲线,与大气湿度、气温日较差关系密切。冬小麦灌浆期间,大气湿度保持在50%~70%之间,千粒重可达38 g以上;气温日较差每增加1℃,千粒重提高0.6553 g。更多还原

【Abstract】 The paper analyses the relations between grouting velocity,thousand-seed weight and atmospheric humidity,daily range of temperature during 1995~2005.The results show they have near relations.The change curve between grouting velocity and thousand-seed weight is of the S type.Thousand-seed weight reaches over 38 g when atmospheric humidity is during 50%~70%.Thousand-seed weight has increased by 0.6553 g as long as daily range of temperature has 1℃ rise.更多还原
