张掖耐盐碱亚麻品种筛选与示范研究

Screening and Demonstration Study on Salt and Alkali Resistant of Flax Varieties in Zhangye City

为筛选生育期适宜、丰产性好、出麻率高、纤维产量高的亚麻品种,高效开发利用张掖盐碱地;以8个亚麻品种为试验材料,以张掖市龙纺麻业提供的山丹为对照,在山丹县位奇镇进行试验;对不同品种原茎产量、种子产量以及其他农艺性状进行田间鉴定;结果表明:8个参试品种的原茎、纤维产量均较当地对照品种山丹大幅度增产,其中华亚5号产量居首,中亚麻3号稍逊,二者原茎较当地对照品种山丹分别增产94.83%和80.85%,达极显著水平;纤维较当地对照品种增产164.74%和147.32%,达极显著水平;华亚5号、中亚麻3号等2个品种(系)在张掖试点综合经济性状、丰产性表现较好,适应性及抗逆性相对较强,可在张掖作为纤维用亚麻品种示范推广.

In order to effectively develop and utilize the saline-alkali land in Zhangye,Gansu Province,flax varieties of appropriate growth period,high yield,high fiber content and resistance to salinealkali were screened.The experiment was carried out in Weiqi Town of Shandan County,using 8 flax va-rieties as experimental materials.The control variety“Shandan”was provided by Longfang Linen Industry in Zhangye City.The stem yield,seed yield,and other agronomic traits of different varieties were meas-ured.The results showed that the stem and fiber yield of the 8 varieties were significantly increased com-pared with the local control variety Shandan.Among them,Huaya 5 had the highest yield,followed by Zhongyama 3.The stem yield of these two varieties increased by 94.83%and 80.85%respectively com-pared with the local control variety Shandan,so does fiber yield by 164.74%and 147.32%respectively,both reaching a very significant level.Huaya 5 and Zhongyama 3 have shown good comprehensive eco-nomic and high-yield performance and very strong adaptability and stress resistance in the experiment,and can be utilized for demonstration planting and promotion in Zhangye.
