中文摘要:

为了推动再生水在干旱半干旱地区的安全利用，进一步拓宽再生水的利用范围，在沧州污水处理厂采用田间试验，研究了再生水灌溉对饲用小黑麦品质的影响。结果表明，再生水灌溉能够显著增加小黑麦籽粒淀粉含量以及籽粒与秸秆中的粗蛋白含量，可以显著提高籽粒中铜、锌、磷的含量以及秸秆中钠、钾、钙、镁和磷的含量；再生水灌溉后，小黑麦籽粒中镉、铅含量与对照相比虽有显著增加，但均未超过饲料卫生标准。由此说明再生水短期灌溉对小黑麦品质无不良影响，且对其淀粉、粗蛋白、矿质元素含量等品质有一定的改善作用。但如果进行长期灌溉，要注意定期监测镉、铅两种重金属含量，防止这两种重金属在其籽粒中积累。

英文摘要:

As a new substitute water resource, reclaimed water is worth for generalizing in pasture irrigation. The influence of reclaimed water irrigation on the quality of forage triticale was studied in Cangzhou sewage treatment factory. The result showed that (1) Reclaimed water irrigation could increase the starch content in the seeds of triticale and the crude protein content in the seeds and stems of triticale significantly. (2) Comparing with that of fresh water irrigation, reclaimed water irrigation could increase the contents of Cu, Zn and P in the of the seeds of triticale and the contents of Na, K, Ca, Mg and P in the stem of triticale. (3) Reclaimed water irrigation could increase the contents of cadmium and plumbum in the seeds of triticale, but which still was less than the national standard of feed health. So the effect of reclaimed water irrigation on the quality of forage triticale was not significant in the short term, and we should monitor the contents of cadmium and plumbum in the seeds of forage triticale if it was irrigated by reclaimed water in long term.
