为了提高油菜田周年经济效益,充分利用油菜苗期的土地、光温资源,进行套种秋马铃薯试验。结果表明,油菜套种秋马铃薯,每公顷纯收入在12000元左右,对地块周年效益增加明显。油菜的直播和移栽方式对油菜的生物学性状有明显影响;油菜的直播和移栽密度对产量有明显差异,直播地块每10000m2播22.5~30万株时产量较高,移栽地块每公顷栽12~18万株时产量较高,效益较好。
In order to improve the annual economic benefits of rapeseed field, make full use of rape seedlings of land, light and temperature resources, intercropping autumn potato test. The results showed that the rape intercropping autumn potatoes, net income per hectare at about 12,000 yuan, significantly increase the annual benefit of plots. The direct seeding and transplanting methods of rape had significant effects on the biological traits of rapeseed. The direct seeding and transplanting density of rape showed significant differences in yield. When the direct seeding plots broadcast 22.5-30 million plants per 10,000 m 2, the yield was high, Planting 120,000-180,000 plants per hectare produces high yield with good benefits.
