| 摘 要： | 试验证明，适时冬灌比早春灌，具有良好的防旱防冻、促根壮蘖增穗作用；小麦越冬期秸秆覆盖能保墒和提高土壤水分的调节能力，为当季小麦生长和套播玉米创造适宜的土壤水分条件；于小麦孕穗和灌浆期喷翠竹生长剂，其增粒增重作用显著。采取冬灌、越冬秸秆覆盖和孕穗、灌浆期喷生长剂等配套措施，可实现保墒与节水相结合，壮苗促蘖增穗与增粒增重的统一，节水增产效果显著。

| Abstract: | This research indicated that winter irrigation of sutable time has better effect on preventing drought and freeze, promoting root growth,enhancing tiller and ear than early spring irrigation. Covering straw of over-winterling could preserve the soil moisture, provide a suitable condition for the growth of wheat and interplating corn.Spraying growth regulator at boot and filling period could increase grain number and weight of wheat significantly. The combination of winter irrigation,covering straw and spraying growth regulator could save water and raise ear and grain number of wheat by preserving soil moisture and promoting tiller.The effect of saving water and raising crop yield are significant. |
