油菜和紫云英混作，在相同的土壤肥力环境条件下进行试验，研究油菜和紫云英混种的7个不同用种量（即混作密度）对油菜植株于物质积累、分枝特性以及产量结构的影响。结果表明：以油菜2．1kg／hm~2，紫云英6、75kg/hm~2混作散播为较适宜的混作种植密度。在这种组合密度下既可以获得较高的油菜产量和紫云英产量，还能为后茬作物增产提供较高的土壤肥力，为实现持续增产打下良好的基础。

Dry matter, branch character and yield components of rape were studied with seven levels of plant densities of mix-cropping system of rape with milk vetch. The results indicated that higher yield of rape and milk vetch could be formed with the appropriate mix-cropping density of 2. 1 kg/hm^2 of rape seeds weight and 6.75 kg/hm^2 of milk vetch seeds weight. At the same time,the mix-cropping density helped to improve fertilizer condition for l...
