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。
Experiments show that timely irrigation in winter than in early spring irrigation, with good drought and frost, and promote the growth of tiller and spike; wheat overwintering period of straw mulching to soil moisture and improve soil moisture regulation ability for the current season wheat growth and set of sowing corn to create appropriate Of soil moisture conditions; booting at the booting stage of wheat and Penicillium sp. Growth agent, the role of grain weight gain was significant. To take winter irrigation, overwintering straw mulching and booting, spraying growth agent during filling and other ancillary measures, can achieve the combination of soil moisture and water, seedling and tillering spikelet with grain weight gain unity, water-saving and yield-producing effect is remarkable.
