故麻是我县的主要油料作物,也是当地种植业中的优势经济作物。据统计1980—1983年在雷大、余湾、双岘、后梁四个寒旱山区年均播种面积9894亩,占农作物播种面积的6.2％;年均单产70斤,产量低而不稳,经济效益差。为此,我们把胡麻生产作为重点,开展了试验示范工作。通过两年来的旱作丰产试验、示范实践,初步总结出适宜当地生产水平,并能够被群众接受的旱区胡麻丰产栽培技术,逐步在生产上大面积推广,取得了较好的经济效益。1984年建立胡麻旱作丰产示范田3200亩,实打和测定320亩,平均亩产113.7斤,比前三年基础亩产70斤,提高了43.7斤,增产62.4％;1985年建立胡麻丰产示范田7037亩,实打和测定
Therefore, Ma is the major oilseed crop in our county and is also the dominant cash crop in the local farming industry. According to statistics, in 1980-1983, the average annual sown area of the four cold and dry mountainous regions of Leida, Yuwan, Shuangxian and Beiliang was 9894 mu, accounting for 6.2% of the sown area of crops; the average annual yield was 70 kg, the output was low and unstable, and the economy Poor efficiency. To this end, we put flax production as the focus, to carry out experimental demonstration. Through two years of dry cultivation experiment, demonstration practice, initially summed up suitable for local production levels, and can be accepted by the masses of flax cultivation techniques, and gradually large-scale production in the promotion and achieved good economic returns. In 1984, 3,200 hectares of flax dry farming demonstration plots were established, and 320 acres were harvested and measured. The average per mu yield was 113.7 kg, 70 kg more than the previous three years, an increase of 43.7 kg and an increase of 62.4%. In 1985, Field 7037 acres, the real fight and determination
