在大量的实测资料基础上，通过模拟计算得到了在当前气候条件下、水肥适宜的青藏高原冬小麦干物质累积动态曲线。模拟计算表明：青藏高原夏季气候温凉，小麦生育期延长，因而干物质累积时间长，高原小麦高产主要以干物质累积时间长取胜，有利的夏季温度条件是高原小麦高产的最主要原因；青藏高原冬小麦干物质潜在产量可达３２ｔ／ｈｍ２·ａ，籽粒潜在产量可达１４４ｔ／ｈｍ２·ａ，为平原的１４５倍。
Based on a large number of measured data, the dynamic curve of dry matter accumulation of winter wheat in the Qinghai-Tibet Plateau under the current climatic conditions was obtained through simulation. The simulation results show that the summer climate is cool and the wheat growing period is prolonged in Qinghai-Tibet Plateau. As a result, the dry matter accumulation time is long, and the high-yielding wheat mainly wins the dry matter accumulation time. The favorable summer temperature condition is the most important reason for the high yield of wheat in the plateau. The potential yield of dry matter of plateau winter wheat reached 32t / hm2 · a, and the potential yield of grain reached 144t / hm2 · a, which was 1.45 times of plain.
