以饲草植物杂交狼尾草（ Pennisetum americanum × P．purpureum）为材料，在黄河三角洲含盐量为0．2％～0．8％的盐碱地上进行增施有机肥对杂交狼尾草产量和品质影响的研究。结果表明，和不施有机肥的对照相比，增施有机肥明显增加杂交狼尾草的产量、改善其饲草品质，其中以施用1500 kg/hm2有机肥处理的杂交狼尾草产量最高，茎叶比最小，鲜干比最大，同时粗蛋白含量最高，相对饲用价值也最大。因此，本试验条件下种植杂交狼尾草，施用1500 kg/hm2有机肥既能满足饲草高产优质的生产需求又能达到最大节约成本的目的，同时也为黄河三角洲盐碱地的开发利用奠定基础。

The forage grass hybrid Pennisetum ( P.americanum × P.purpureum) was used as experi-mental material .The effects of different amounts of organic fertilizer on its yield and quality were studied in sa-line soil with salt content as 0.2%~0.8%from the Yellow River Delta.Compared to the treatment with no organic fertilizer , the added application of organic fertilizer obviously improved the yield and quality of hybrid Pennisetum.The yield of forage grass was the highest with the lowest ratio of stem to leaves and the highest ra-tio of fresh weight to dry weight , when the application rate of organic fertilizer was 1 500 kg/hm2;meanwhile, the content of crude protein ( CP) and relative feed value ( RFV) were the highest .In conclusion , the appli-cation of 1 500 kg/hm2 organic fertilizer for hybrid Pennisetum under this experimental condition could not only obtain high-yielding and high-quality forage grass , but also save cost maximum .It provided basis for explo-ration and utilization of the Yellow River Delta .
