　　为了获得高产、高蛋白的牲畜粗饲料，通过研究黑龙江省西部地区不同种植密度和施肥水平对龙引扁豆1号与青贮玉米混种的影响，筛选出了适合该地区的较优栽培模式。结果表明：随着龙引扁豆1号密度的增加，其混种生物产量显著增加，当龙引扁豆1号的种植密度与青贮玉米的种植密度均为60000株?hm‐2时，混种生物产量最高，平均为53359．99和56933．20 kg?hm‐2；追施尿素的施用量在300～375 kg?hm‐2增产显著；通过对种植密度和施肥水平搭配组合筛选黑龙江省西部地区龙引扁豆1号与玉米混种的较优栽培模式，龙引扁豆1号播种密度60000株?hm‐2＋施肥（尿素）375 kg?hm‐2的栽培模式组合混种增产效果最好，比对照组合平均增产16．76％。

In order to obtain livestock roughage of high yield ,high protein ,optimal cultivation modes on mixing planting of L ablab purpureus and silage maize were screened through different cultivations in western region of Heilongjiang province(planting density condition ,and fertilization) .The results showed that biological yield of mixture increased significantly with the increase of plant density of Lablab purpureus .When the planting den-sity of silage maize and L ablab purpureus were all 60 000 plants?hm‐2 ,the average value of biological yield was the highest ,achieve 55 146 .60 kg?hm‐2 .Fertilization between 300~375 kg?hm‐2 increasd yield significantly . According to planting density and fertilization ,the optimal cultivation modes were selected in Heilongjiang province .There was a better yield which was 16 .76% higher than the control in western region ,when the planting density was 60 000 plants?hm‐2 ,fertilization volume was 375 kg?hm‐2 .
