Effects of Cultivation Methods on Water Consumption Yield and Water Use Efficiency of Winter Wheat
To study the effects of different cultivation methods and irrigation schedules on growth
yield
and water use of winter wheat
three cultivation modes were conducted with field experiment in Shandong province:Traditional Cultivation (TC)
Ridge Cultivation (RC)
and High and Low Cultivation (HLC)
three levels of irrigation quota (900 m3/hm2
720 m3/hm2
540 m3/hm2) were set up in RC and HLC respectively
while there was only 900 m3/hm2 irrigation quota for TC. The changes in soil moisture
water consumption
and water use efficiency (WUE) of winter wheat in the three cultivation methods were studied. The results showed:the soil water content of winter wheat at different growth stages was significantly different under different cultivation methods
and the ability of storing rainfall in RC method was better than the other two methods. The cultivation methods had significant effects on the water consumption characteristics and water use efficiency of winter wheat
and there was a significant positive correlation between winter wheat yield and water consumption (R2=0.86
P<0.01). Compared with RC and TC
the wheat of HLC developed vigorously
with higher number of panicles and grains per mu. The total water consumption under HLC method was 14.16% and 19.90% higher than that of TC and RC respectively
while the yield of HLC was 22.63% and 27.37% higher than that of TC and RC respectively. Furthermore
the WUE of HLC was 7.69% and 6.87% higher than that of TC and RC. Overall
HLC cultivation can significantly improve the yield and WUE of winter wheat
and it could be an ideal water-saving and high-yield cultivation method in the study area.
