亚麻是我国阴山北部丘陵区的主要油料作物。历年播种面积约四百万亩左右,占全国油用亚麻的三分之一左右。但产量很低,据河北省张家口地区坝上各县1961至1965年统计,平均亩产只有41.1斤。经考察亚麻产量低的原因,除栽培条件外,主要是品种单一,尤其缺乏适宜旱地种植的中熟高产品种。为此,我所根据坝上自然条件和生产需要,明确了亚麻新品种的选育目标是:1、生育期:100—110天,比推广品种匈牙利三号,雁农一号晚熟5—10天。
Flax is the main oilseed crop in the northern hilly area of China. The sown area over the years about four million acres, accounting for about one-third of oil used in the country. However, the output is very low. According to statistics from 1961 to 1965 in counties in Zhangjiakou, Hebei Province, the average yield per mu was only 41.1 kg. After examining the reasons for the low yield of flax, apart from the cultivation conditions, the main varieties are single varieties, especially the lack of suitable medium-yielding high-yielding varieties suitable for dryland cultivation. To this end, I based on the natural conditions and production needs of the dam, a clear selection of new varieties of flax breeding objectives are: 1, growth period: 100-110 days, than the promotion of varieties of Hungary on the 3rd, Yannong One late 5-10 day.
