Abstract

The field experiments were carried out to study the different water treatments’ influences on water consumption and yield of winter wheat in two different planting patterns (conventional flat planting and ridge tillage furrow irrigation planting). The results showed that,compared with the conventional flat planting pattern,in ridge tillage furrow irrigation,the water consumption in the whole stages reduced 26.26~31.92mm;spike grain number and grain weight grew by 6.09% and 3.79%,respectively;yield increased 150.57~237.63kg/hm2;and the water use efficiency (WUE) improved about 9.43%~10.39%. The water consumption and yields showed positively correlation with water treatments,but the WUE increased firstly and then decreased as the increase of moisture control limit. The ridge tillage furrow irrigation was determined as the more appropriate planting pattern for winter wheat,and the highest WUE was obtained in L-70 water treatment,which reached 1.91 kg/m3,and yield reached 7589.96 kg/hm2.
