通过研究不同栽培模式(种植密度、施肥水平、灌水)对龙引扁豆1号与青贮玉米混种的影响,筛选出了龙引扁豆1号与青贮玉米混种的较优栽培模式.结果表明:在保证青贮玉米原高产的种植密度下,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相一致时,二者混种的生物产量最高,过密则造成严重倒伏;追施(尿素)的施用量在225~300 kg?hm‐2时增产显著;灌水处理则能显著提高混种产量,最佳的灌水时期分别在苗期和拔节期,灌水量为30 mm?次‐1.通过对种植密度、施肥水平、灌水水平等栽培模式搭配组合筛选出了龙引扁豆1号与玉米混种的较优栽培模式,龙引1号扁豆播种密度47000株?hm‐2+施肥(尿素)225 g?hm‐2+灌水2次的栽培模式组合混种增产效果最好,比对照组合增产23.28%.

The optimal cultivation mode on mixing planting of L ablab purpureus (Longyin Lentil No .1) and si‐lage maize was screened through different cultivations (planting density condition ,irrigation and fertilization level) .The results showed that biomass yield of mixture increased significantly with the plant density of L ablab purpureus increased ,under the condition that the planting density of silage maize was guaranteed ,and the value of biomass yield was the highest when planting density of L ablab purpureus and silage maize was equal ,while exceeding of the planting density of silage maize could cause serious lodging ;Fertilization had significant yield increasing between 225 ~ 300 kg?hm‐2 ;Irrigation could improve the yield significantly ,and the best irrigation stages were seedling and jointing stage respectively ,and the optimum volume was about once 30 mm ;According to planting density ,fertilization and irrigation experiment ,the optimal cultivation mode was selected in Hei‐longjiang province .There was the highest yield which was 23 .28% higher than the control ,when the planting density was 47 000 plants?hm‐2 ,fertilization volume was 225 g?hm‐2 ,and irrigation twice .
