摘要
在鄂尔多斯地区,对准格尔苜蓿进行再生水和自来水混合灌溉试验,同时研究在正常灌水量80%和60%的条件下喷施植物抗蒸腾剂的影响,测定准格尔苜蓿的产草量、粗蛋白质含量及中性洗涤纤维含量指标,分析再生水和自来水混合灌溉的适宜比例和灌水量。结果表明,再生水和自来水2∶1混合灌溉能明显增加准格尔苜蓿产草量,施用抗蒸腾剂可以节约20%的灌水量。
Field experiment of reclaimed water and tap water mixed irrigating on Zhunger alfalfa was conducted in Ordos,the effect of antitranspirant under the condition of the normal irrigation amount of80%and 60% on drought resistance were studied,the yield,CP and NDF were tested,and proportion and amount of reclaimed water and tap water mixed irrigation were studied.The results indicated that mixed water irrigation of reclaimed water and tap water in ratio of 2∶1could obviously increased yield,applying antitranspirant could save irrigation water by 20%.
