在小麦的安全发育与产量丰歉上,生育速度是个至关紧要的问题.大田生长中各年之间很难看到小麦各生育时期的生长发育速度完全一致,它们特别容易随着不同年际的气候波动而或多或少地变化,造成产量不稳定.国内外已充分认识到生育速度的生产意义,把对小麦生育进程的预测做为灵活掌握田间管理时宜,确定收获适期和进行产量预报的重要基础,而且不少研究工作,已取得了肯定的进展.
Fertility is a crucial issue in the safe development of wheat and the abundance of output.During the growth of the field, it is hard to see that the growth and development rates of wheat during different growth stages are exactly the same, and they are particularly vulnerable to different years Climate change and more or less fluctuate, resulting in unstable output.While at home and abroad have fully realized the meaning of the birth rate of production, the prediction of the process of wheat growth as a flexible grasp of field management time, to determine the appropriate harvest and yield forecast Of the important foundation, and a lot of research work, has made some positive progress.
