在冬小麦生育期降水量不少于１４０ｍｍ、上层厚度１ｍ以上的无水浇条件地区，利用旱作栽培技术，即增施磷、钾和锌肥，发挥旗叶节以上绿色器官的光合能力，则可获得４９５０ｋｇ／ｈｍ２左右的籽粒产量，旱作栽培小麦植株各营养器官１４Ｃ同化物对籽粒的贡献为８３．７３％，对照为７５．３１％；旱作栽培小麦旗叶节以上器官对籽粒的贡献为５２．０３％，对照为５６．６１％。旱作栽培小麦旗叶的脯氨酸含量及旗叶节以上各主要器官叶绿素含量均显著高于对照。
In the areas with no water with less than 140mm of precipitation during the growth period of winter wheat and above 1m in thickness of the upper layer, the photosynthetic capacity of green organs above the flag leaf stage is utilized by using dry cultivation techniques, that is, adding phosphorus, potassium and zinc fertilizer The grain yield of 4950kg / hm2 could be obtained. The contribution of 14C assimilate of vegetative organs of dry-cultivated wheat plant to grain was 83.73% and the control was 75.31% The contribution was 52.03% and the control was 56.61%. The proline content of flag leaf and the chlorophyll content of all major organs above flag leaf node in cultivated wheat were significantly higher than those in control.
