摘　　要：通过对贵草1号多花黑麦草的不同密度和施肥量对其鲜草产量和牧草高度的影响研究,结果表明:在不同密度和施肥量条件下,贵草1号多花黑麦草的产量和生长高度有显著差异,当施基肥为有机肥1000kg/667m2+尿素10kg/667m2,行距为20cm时,贵草1号生长速度最快,平均高度最高,达到64.2cm,鲜草产量最高,达到3164kg/667m2。Effects on grass yield and height of Guicao 1 annual rye grass on different density and fertilization were studied. The results showed： in different density and fertilization, grass yield and height of Guicao 1 annual rye grass had marked difference. When fertilization was organic fertilizer 1000kg/667m2＋ urea 10kg/667m2 and row pitch 20cm, the Guicao 1 annual rye grass growth speed was fastest, average height was 64.2cm. the grass yield reached highest 3164 kg/667m2.
