| 摘 要： | 莜麦全生育期耗水量和各生育阶段耗水量都与供水量密切相关，随着供水量提高，全生育期总耗水量和各阶段平均每天耗水量均增加，籽粒产量和生物产量也同步增加．莜麦籽粒产量对水分最为敏感的时期是孕穗期，其次是开花至灌浆期，这些阶段缺水，籽粒产量会大幅度减少；生物产量主要表现为前期缺水，后期供水时，产量较高，而对某一时期缺水较不敏感．

| Abstract: | Based on analyzing the situation of water consumption during the Jixibei Dry-land Naked oafs growth period and the regularity of the local rainfall, we can hereby adjust the Naked oat seeding time in order to realize the synchronization between water requirement for Naked oafs growth and rainfall, so as to make the best use of the rainfall and increase in the yield. The results showed that the first stage which the yield of seed was sensitive to the lack of water was Booting and second ones are Flowing and Grain filling. So its biological yield was related to supplying amount of water. |
