摘　　要：通过对比方法对"玉米田养鹅"处理(RGICF)农田植株营养价值及营养输出量进行分析。结果表明,RGICF处理地上部植株干物质含量和粗纤维含量分别低于对照,粗蛋白、粗脂肪、灰分含量分别高于对照,除灰分指标处理间差异显著(P<0.05)外,其他指标处理间差异不显著(P>0.05)。RGICF处理碳氮营养比明显低于对照,处理间差异不显著(P>0.05);RGICF处理田间植株干物质含量、粗纤维、钙和磷输出量分别低于对照,粗蛋白、粗脂肪、灰分输出量分别高于对照,上述指标处理间差异均不显著(P>0.05)。RGICF处理每公顷地上植株数量载畜量为8.62个牛单位,低于对照0.64个牛单位;地上植株粗蛋白载畜量为3.96个牛单位,高于对照0.09个牛单位。因此,RGICF处理明显提高田间地上植株的饲用营养价值,增加CP载畜量。The nutritional value and nutrient output of plant in the cornfields of raising geese (RGICF)were an- alyzed.The results showed that the dry matter content,crude fiber content of the aboveground plants in RGICF were lower than that in the CK,while the crude protein(CP),crude fat and ash content in RGICF were higher than that in the CK.Except the difference was the significant for ash indicators between the treatments(P<0.05),the differences among other indicators were not significant(P>0.05).The ratio of carbon to nitrogen nutrition in RGICF was significantly lower than 2.41 in CK,and the difference between treatments was not significant(P>0.05).The output of dry matter,crude fiber,calcium and phosphorus in the field of RGICF treatment were respectively lower than that of CK,while the CP,crude fat and ash output were respectively higher than that of CK,and there was no significant difference among the above indexes(P>0.05).The amount of carrying capacity was 8.62cattle unit/ha in RGICF,which was 0.64 lower than the CK,but the CP of the aboveground plants was 3.96cattle unit/ha,which was 0.09cattle unit/ ha higher than that in the CK.So RGICF treatment significantly improved the feeding nutritive value of the aboveg- round plants in the field,and increased the CP carrying capacity.
