我县位于闽东北山区,界于北纬27°08′～27°17′之间,境内山恋起伏,一般海拔高度在600～800米之间。气候特点,春暖迟,秋寒早,无霜期仅有230天,长期来以种植单季稻为主.虽有种植油菜实行一油一稻的耕作制,但过去种植白菜型本地种,栽培技术不讲究,亩产徘徊在三、五十斤。为了解决油菜低产问题,一九七八年宁德地区农科所柘荣基点引种了中国农科院油料所新培育的甘油五号在城关公社的南街大队和县良种场试种,面积20.05亩,总产4548斤,平均亩产222斤,一九七九年冬全县种植甘油五号4600多亩,占油菜总面积的70％左右,虽播栽时遇上严重秋冬干旱,后期油菜开花结
My county is located in the northeastern Fujian mountainous area, between latitudes 27 ° 08 ’~ 27 ° 17’, the territory of mountain love ups and downs, the general altitude of 600 to 800 meters. Climate characteristics, late spring, early autumn cold, frost-free period of only 230 days, long-term to single-cropping rice-based.Although rapeseed oil cultivation practice of a rice system, but the past planted cabbage-based native species, cultivation techniques pay attention to, Yield hovering in three or five pounds. In order to solve the problem of low yield of rapeseed, in 1978, Ningde Prefecture Agricultural Science Institute Rongji point introduction of the Chinese Academy of Agricultural Sciences oil cultivated glycerol fifth in the Chengguan commune South Street brigade and county seed field trial, an area of 20.05 mu , With a total yield of 4548 catties, with an average yield of 222 kilograms. In the whole of 1979, 4600 mu of glycerin was planted in the county, accounting for about 70% of the total area of rape. Although rapeseed had severe drought in autumn and winter, Knot
