| 试验使用免发酵鹅粪施用于杂交狼尾草（Pennisetum americanum × P. purpureum），探讨杂交狼尾草施用免发酵鹅粪的可行性。与对照组相比，化肥、免发酵鹅粪、腐熟鹅粪处理对杂交狼尾草各农艺性状及品质均产生显著性影响。三组施肥处理中，化肥和免发酵鹅粪对杂交狼尾草各农艺性状及品质的影响差异性不显著。整体来看，在提升和改善杂交狼尾草产量、品质方面，腐熟鹅粪效果最好，第一次刈割，免发酵鹅粪效果劣于化肥，但在第二、三次刈割，免发酵鹅粪效果优于化肥。对杂交狼尾草地土壤化学性质进行测定后发现，单施化肥组土壤有机质和矿质营养含量均呈下降趋势。施用腐熟鹅粪和免发酵鹅粪肥既能保证和提高杂交狼尾草产量和品质，又能提高土壤有机质含量：免发酵鹅粪组和腐熟鹅粪组土壤有机质分别提高了8%、12%，均能保证其他矿质元素含量的稳定和提升。通过对比杂交狼尾草的生长指标，得出免发酵鹅粪并未对杂交狼尾草产生不良影响，虽然整体效果没有腐熟鹅粪好，但与化肥组提升杂交狼尾草产量和品质效果相同，而且免发酵鹅粪提升土壤肥力的效果更显著。说明用免发酵鹅粪直接施用于杂交狼尾草地是一种可行的方式。 |

| Abstract: |
| In this experiment, the fermented goose feces was applied to Pennisetum americanum × P. purpureum to explore the feasibility of applying fertile goose feces to P. americanum × P. purpureum. Compared with the control group, chemical fertilizer, fermented goose feces, and decomposed goose manure treatment had significant effects on the agronomic traits and quality of P. americanum × P. purpureum. In the three groups of fertilization treatments, the differences in the agronomic traits and quality of the chemical fertilizer and the fermented goose feces in the P.
americanum × P. purpureum were not significant. On the whole, the effect of decomposed goose feces is always the
best in improving the yield and quality of P. americanum × P. purpureum. The first mowing the fermented goose
feces is inferior to the fertilizer, but in the second and third times, it is free of fermentation. Goose feces are better than fertilizers. The soil chemical properties of the hybrid wolftail grassland were determined, and the soil organic matter and mineral nutrient contents of the single application fertilizer group showed a downward trend. Application of decomposed goose feces and fermented goose manure can not only ensure and improve the yield and quality of P. americanum × P. purpureum, but also increase the soil organic matter content: the soil organic matter in the fermented goose feces group and the decomposed goose feces group increased by 8% and 12%, respectively. All can guarantee the stability and improvement of other mineral elements. By comparing the growth indexes of P. americanum × P. purpureum, it is concluded that the fermented goose feces does not have adverse effects on hybrid Hydrangea. Although the overall effect is not good in decomposed goose feces, it has the same effect as the fertilizer group in improving the yield and quality of P. americanum × P. purpureum. And the effect of the fermented goose feces to enhance soil fertility is more significant. It is indicated that direct application of fermented goose feces to hybrid wolftail grassland is a feasible way. |
