摘要：

摘要：通过创造性地引用节水高产栽培、因土平衡施肥等技术，基本做到了经济利用水、肥、土资源；在三年的高产实践中，实现了粮食单产保持1.4t/667m2以上水平的同时，水分生产效率达到2 kg/m3以上高水平，按土壤、肥料实际供应有效养分总量计算的养分生产效率也基本达到7 kg/kg以上，且粮食单产达到1524.75 kg/667m2时，总有效养分生产效率提升至8.07 kg/kg，较好地体现了高产高效同步。

Abstract:

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.
