中文摘要：

于2011年在内蒙古武川县研究了沙地改良剂对土壤水分及燕麦产量和品质的影响。结果表明，沙地改良剂能够明显提高0—60cm土层土壤含水量，其中以12000kg／hm2施用量效果最佳；施用量6000kg／hm2、12000kg／hm2、18000kg／hm2和24000kg／hm2沙地改良剂土壤水分利用效率较对照分别显著提高了14．50％、25．70％、13．28％和5．86％；不同用量沙地改良剂处理较对照增产显著，当施用量为12000kg／hm2时，燕麦籽粒产量和生物产量最高，达4884．4kg／hm2和13001．3kg／hm2，施用量为18000kg／hm2时次之；沙地改良剂对燕麦籽粒粗蛋白、赖氨酸和β-葡聚糖含量影响显著，均以12000kg／hm2施用量时效果较佳，施用量过大或过小都不利于燕麦品质的提高。

英文摘要：

The effects of different amounts of sandy soil amendment on soil water, oat yield and quality were studied in Wuchuan County of Inner Mongolia in 2011. The results showed that sandy soil amendment could improve significantly the soil water content of each layer in 0 - 60 cm depth, and the amount of 12 000 kg/hm2 was the best. Compared with CK, the WUE of the amount of 6 000 kg/hm2, 12 000 kg/hm2, 18 000 kg/hm2 and 24 000 kg/hm2 increased by 14.50%, 25.70%, 13.28% and 5.86%. Oat yield was significantly affected by sandy soil amendment, and when the amount was 12 000 kg/hm2, the grain yield and biological yield all were the highest and when 18 000 kg/hm2, it was the second. Sandy soil amendment had siginficant effect on crude protein, lysine and β- glucan content, and the amount of 12 000 kg/hm2 was the best. Excess or lack of application amount were all bad for the increase of oat quality.
