胡麻又叫亚麻,韧皮纤维作物,属亚麻科,亚麻属,一年生草本植物。栽培种有大粒种、中粒种和小粒种三个亚种,以小粒种栽培广泛。按用途又分纤维用亚麻、油用亚麻、油纤兼用亚麻和葡萄亚种四类。雁北栽培为油用亚麻,子可榨油,油粕可作饲料。目前全区共种油料作物100万亩,胡麻就占88%。雁北地区气候凉爽,日照充足,有利于胡麻油份的形成和积累。胡麻生长期间的4—8月份平均气温在11—22℃之间,有效积温2,324℃,年日照时数2,882小时。这些自然条件与胡麻生长发育对光温的要求是一致的;其次我省胡麻主要产区土地广阔,大面积种植可以轮作倒茬;第三,十年九旱,无霜
Flax also known as linen, bast fiber crops, is a linen, flax, annual herb. Cultivars are large species, medium species and small species of three subspecies, a wide range of cultivation of small grains. Divided by the use of sub-fiber linen, oil with linen, linen and linen fibers with four subspecies. Yan North cultivation of oil with linen, child can be pressed oil, oil meal for feed. At present, a total of 1000000 acres of oil crops crop, flax accounted for 88%. Yanbei area cool climate, adequate sunshine, is conducive to the formation and accumulation of flax oil. Flax during the April-August average temperature between 11-22 ℃, effective accumulated temperature of 2,324 ℃, the annual sunshine hours 2,882 hours. These natural conditions and flax growth and development requirements of light and temperature are the same; secondly, the main areas of flax in our province is vast land, large areas can be rotated crop rotation; third, ten nine drought, no frost
