栽培面积和产量 近十年来,瑞典油料作物(油菜)面积徘徊在16万公顷左右,约占可耕地总面积的6%,其中约有1/3种植冬油菜,1/3春油菜和1/3春性白菜型油菜。最近几年,冬性白菜型油菜面积很小。 表1列示1986,1987年油菜收获面积、产量、种子含油率和种子叶绿素含量。冬油菜面积取决于秋播和越冬条件。1985年秋,冬油菜的播种面积为4.6万公顷,1988年秋为6.1万公顷。最近两年冬季非常寒冷,1985—1986年和1986—1987年间分别有18.3%和21.5%的播种面积因受寒害而改种其它作物。表内种子产量数值已按合水量18%的标准调整,种子含油率是以占干物重的百分比计算的。
Cultivated area and output In the last decade, the area of Swedish oil crops (canola) hovered around 160,000 hectares, accounting for about 6% of the total arable land, of which approximately one-third were planted with winter rapeseed, ½ spring rapeseed and 1 / 3 spring cabbage rape. In recent years, winter cabbage rapeseed area is very small. Table 1 shows the harvest area, yield, seed oil content and seed chlorophyll content of canola in 1986 and 1987. Winter rapeseed area depends on the autumn sowing and winter conditions. In the autumn of 1985, winter rape sown area was 46,000 hectares, compared with 61,000 hectares in autumn 1988. In the recent two years, the winter was very cold. From 1985 to 1986 and from 1986 to 1987, 18.3% and 21.5% of the planted area were planted with other crops due to chilling injury. Table seed yield values have been adjusted according to 18% of the amount of water standards, seed oil content is calculated as a percentage of dry weight.
