胡麻是我国四大油料作物之一。胡麻种子含油量一般是36.5—49.5%,高者可达50.9%,含油量仅次于花生,高于向日葵、大豆、大麻等作物。胡麻含油量是可变数,影响含油量的多少、高低的因素较多。我们通过对156份不同胡麻类型的品种材料进行含油量的测定分析,初步探明胡麻含油量与品种、经济性状、栽培条件有关系。这对胡麻的栽培、育种、引种、推广有重要现实意义。一、温差大含油量高胡麻是个耐低温作物,温 Flax is one of the four major oil crops in China. Flax seed oil content is generally 36.5-49.5%, the highest up to 50.9%, second only to peanut oil content, higher than the sunflower, soybean, cannabis and other crops. Flax oil content is variable, how much oil content, high and low factors. Based on the determination of 156 oilseeds from different flax varieties, we initially ascertained that the oil content of flax is related to the varieties, economic traits and cultivation conditions. This flax cultivation, breeding, introduction, promotion has important practical significance. First, the temperature difference between the high oil content flax is a low temperature crops, warm
