Screening and Demonstration Study on Salt and Alkali Resistant of Flax Varieties in Zhangye City
In order to effectively develop and utilize the saline-alkali land in Zhangye,Gansu Prov-ince,flax varieties of appropriate growth period,high yield,high fiber content and resistance to saline-alkali 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.
