【Objective】 The objective of this experiment was to study the effects of irrigation stage and amount on water consumption characteristics and grain protein components of wheat under high-yield conditions, and to provide scientific basis for water-saving, high-yield and good-quality cultivation of wheat.

It showed that,the more irrigation water and shorter irrigation cycle,the higher the potato plants were;The time for the stalk thick beginning to attenuate is earlier than the height to attenuate for more than 10 days,and the attenuate range was larger than the plant height.
