１９９３～１９９４年在中国农业大学科学园进行了冬小麦节水灌溉试验。通过对干物质积累、分配动态观测表明：供水较多、供水较早的处理，干物质累积总量及根、冠生长量较大。根量最大值出现在开花期，在此之前，根、冠同步增长并呈正相关；之后，由于根系不断衰亡出现负相关关系。土壤水分不足，分配到根系的干物质比例及根冠比（Ｒ／Ｓ）增大，拔节期及其之前的土体水量对Ｒ／Ｓ影响较大，之后的对Ｒ／Ｓ影响很小。冬小麦在扬花与拔节期对水分条件较为敏感，其中扬花水显得更为重要，应特别注意加强扬花、灌浆期水分管理。
1993 to 1994 in China Agricultural University Science Park winter wheat water-saving irrigation experiments. Dynamic observation of dry matter accumulation and distribution shows that more water supply, earlier treatment of water supply, total dry matter accumulation and larger root and crown growth. The maximum root volume appeared in the flowering period. Before that, the root and the crown increased in a synchronous manner and positively correlated with each other. Later, there was a negative correlation due to the decay of the root system. The soil moisture was insufficient, the proportion of dry matter distributed to the root system and the root / shoot ratio (R / S) increased. The water content of soil before and after jointing had a greater effect on R / S, and had little effect on R / S afterwards. Winter wheat flowering and jointing stage of the water conditions are more sensitive to flowering water is more important, should pay special attention to enhance the flowering, filling water management.
