小麦后期(灌浆乳熟期)灌水试验从1973年开始进行定点试验,1981年又在扶风、杨陵、乾县及兴平四县(区)设置了后期不同时间的灌水对比试验。通过多年试验资料分析,后期灌水具有保墒防旱、抗御干热风的危害、促进小麦正常成熟、增粒增重及充分利用水源,达到“一水管两料”的效果。冬小麦后期灌水具有以下优点: 1.增加土壤储水,保墒防旱,水保根,根保叶,叶保籽。小麦生长后期,耗水量大,保持适宜的土壤水分是提高粒重的重要条件。根据扶风
The latter part of wheat (grouting milk ripening period) irrigation test from 1973 to carry out fixed-point test in 1981 and in Fufeng, Yangling, dry county and Xingping four counties (districts) to set the irrigation contrast test at different times later. Through many years of experimental data analysis, post-irrigation has the effect of moisture preservation and drought prevention and protection against hot and dry wind, and promotes the normal maturation of wheat, grain weight gain and full utilization of water sources, achieving the goal of “one water pipe”. Late irrigation of winter wheat has the following advantages: 1. Increase soil water storage, moisture conservation drought, water security root, leaf leaves, leaf seed protection. Late stage of wheat growth, water consumption, to maintain appropriate soil moisture is an important condition to improve grain weight. According to Fufeng
