鹅粪与化肥对牧草产量及其营养成分的影响

在苜蓿Medicagosativa和黑麦草Loliummultiflorum人工草地上分别施用鹅粪、化肥进行比较试验,探讨不同肥料种类对牧草产量及其营养成分的影响。结果表明:施用鹅粪与施用化肥相比,苜蓿产量和粗蛋白含量分别提高29 4%和11 2%,黑麦草提高6 2%和13 9%;2种肥料对牧草纤维成分虽有一定的影响,但差异均不显著(P>0 05);在人工草地上施用鹅粪能显著提高牧草产量和粗蛋白含量,改善其营养。

Organic and inorganic fertilizer influence differences on the yield and nutrient components of forages

Goose faeces and inorganic fertilizer (nitrogen, phosphorous and potassium) were applied to Medicago sativa and Lolium multiflorum cultivated pasture swards to compare their effects on the yield and nutrient components of two forage types. Compared with inorganic fertilizer, goose faeces increased the M. sativa yield and crude protein content by 29.4% and 11.2%, respectively, and L. multiflorum Lam yield and crude protein content by 6.2% and 13.9%, respectively. Difference in fertilizer type did not result in any significant differences in the fibre component within the same forage species (P>0.05). The yield and crude protein content of cultivated pasture can be improved by applying goose faeces, improving the pasture's nutritive value.
