施用鹅粪与化肥对牧草生物量和土壤肥力的影响

EFFECT OF GOOSE FECES AND CHEMICAL MANURE ON BIOMASS OF HERBAGE AND FERTILITY OF SOIL

在苜蓿和黑麦草人草地上施用鹅粪，与施用化肥比较，探讨不同种类肥料对牧草生物量和土壤肥力的影响。结果表明，给苜蓿施用鹅粪与施化肥比较，能提高牧草产量２５％～３５％左右，提高根系干物质量１５／～３０％左右；给黑麦草施用鹅粪，能提高牧草产量６％左右，提高根系干物质量１７％左右。同时，鹅粪可使人工草地土壤有机质含量提高１１％左右，全Ｎ、全Ｐ和全Ｋ均有很大提高。施用鹅粪对提高人工草地牧草产量和土壤肥力均有明显的促进作用。

Fertillzing goose feces in the artificial grassland of M,sativa and L.multiflorum as compared withchemical manure,the result showed that goose feces could make the yield of M. sativa increased by 25%～35%, dry matter of roots increased by 15%～30%;The yield of L. multiflorum increased by 60%, drymatter of roots increased by 17%. Meanwhile,goose feces could make the contents of soil organic matter ofthe artificial grassland increased by 11%. Full N and full P and full K all increased greatly. Goose feceshad a significant improving effect on yield of artificial grass, and fertility of soil.
