Abstract: Water-saving high-yield cultivation and balance fertilization decision technology was used in order to utilize water, fertilizer and land resource economically. In three years high-yield experimentation, grain yield was upper 1400 kg/667m2, water production efficiency was also higher than 2 kg/m3 and nutrient supplied practically by soil and fertilizer production efficiency was more than 7 kg/kg at the same time. When grain yield was 1524.75 kg/667m2, the total nutrient production efficiency was up to8.07 kg/kg, high yield grew in step with high efficiency.
