摘　　要：黑龙江省不同地方的气候、土壤环境条件差异极大,亚麻原茎产量、纤维产量和纤维含量在不同地点间、品种间和两者的互作均达到极显著水平,因此有必要对黑龙江省亚麻进行高产区划分,选择适宜的品种在适宜的区域种植,全面提高黑龙江省亚麻纤维的产量。相关分析显示,土壤全磷含量与原茎产量、纤维产量和纤维含量均存在较大的正相关关系,而与速效磷含量不相关;酸碱度与3者均呈负相关关系;另外有机质含量与3者均呈正相关关系,全氮与原茎产量呈正相关关系,与其他指标不相关,碱解氮含量与产量不相关,速效钾含量与纤维含量呈著负相关。对3个品种的分析显示,碱解氮、速效磷和酸碱度对纤维产量的直接通径系数均为正值,而速效钾是负值。The differences of environmental condition of climate and soil of different region of Heilongjiang Province are great. Flax straw yield among different place or the variety and the interaction between place and variety all reached significance level extremely, fibre yield and fibre content so on. The results showed that carry on high yield zoning to Heilongjiang Province, and choose the most suitable region, to improve totally the flax yield of Heilongjiang Province. Positive content of total phosphorus of soil and the straw yield, fibre yield or fibre content of rapidly available phosphorus and them was independent. They variety to be planted in correlations were found content, and correlation were negative with pH the optimum between the between the of soil, and positive with organic matter of soil. Total nitrogen content was positive correlation with straw yield, and was independent with other index. It was independent that the alkali-hydrolyzable nitrogen content with the yield, the content of rapidly available potassium and fibre content was high negative relations. The analysis on three varieties showed that the direct path coefficients of alkali-hydrolyzable nitrogen, the rapidly available phosphorus and pH to fibre yield were positive, and the rapidly available potassium＇s was the negative value.
