春小麦是扬黄新灌区主要农作物。春小麦生长期 3月中旬至 7月中旬自然降水量只有 80～ 10 0mm ,蒸发量大 ,只有通过灌溉来补充水分才能保证春小麦的正常生长。在当前水资源紧缺的条件下 ,如何灌溉才能达到节水、高产、稳产的目的 ,是扬黄新灌区亟待解决的问题。本文根据试验资料 ,分析了土壤水分对春小麦生长发育的影响 ,提出了合理的灌溉方案
Spring wheat is the main crop in Yang-Huang new irrigation area. Spring wheat growing season from mid-March to mid-July natural precipitation is only 80 ~ 10 0mm, evaporation, and only by irrigation to supplement the moisture in order to ensure the normal growth of spring wheat. Under the current shortage of water resources, how to achieve the purpose of water-saving, high-yielding and stable production is an urgent problem to be solved in Yanghuang New Irrigation District. Based on the experimental data, this paper analyzed the effect of soil moisture on the growth and development of spring wheat and put forward a reasonable irrigation program
