承德地区坝上,无霜期100天左右,历年种植胡麻20万亩以上。由于种性增产潜力小,一般平均亩产在30公斤左右,致使我区油脂供应长期以来不能自给,每年要从外地调入500万公斤。1982年引进加拿大育成的托尔(TOWEY)油菜,经过试验、示范,单产比胡麻成倍增长,效果十分显著。1990年在围场、丰宁县推广6.61万亩,平均亩产达到98.6公斤,最高达294公斤,比对照1万亩胡麻的平均亩产26公斤.增产72.6公斤,亩增收50.20元,不但提高了本区油脂供应能力,而且为农民脱贫致富创造了条件。
Chengde dam, frost-free period of about 100 days, over 200,000 acres of planted flax over the years. Due to the small potential for increasing productivity, the average yield per mu is about 30 kg, resulting in the long-term lack of supply of oil in our region. Each year, 5 million kg should be transferred from the rest of the country. Introduced into Canada in 1982 Toll (TOWEY) rape, after testing, demonstration, doubled yield more than flax, the effect is very significant. In 1990, in the paddock and Fengning County, 66,100 hectares were popularized, with an average yield of 98.6 kilograms and a maximum of 294 kilograms, an average yield of 26 kilograms per hectare of flax, an increase of 72.6 kilograms and an increase of 50.50 yuan in mu, District oil supply capacity, but also to create conditions for farmers to get out of poverty.
