环境条件对亚麻纤维品质的影响

品种区域试验结果显示,黑龙江省不同地区的气候、土壤环境条件差异极大,亚麻纤维强度在不同(区域)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(种植)进行优质区划,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品质。相关分析表明,土壤缓效钾和速效钾含量与纤维强度和可挠度均呈正相关,其它指标与两个品质指标间呈负相关。土壤全磷和速效磷含量与可挠度呈显著负相关,速效磷与纤维强度呈较大的负相关,有机质含量、全氮含量与之呈较大的正相关,二者与可挠度呈负相关。3个品种的纤维强度与开花前后的气象因子的关系比较复杂,开花前日照时数与强度负相关;开花后较多的积温、日照时数和降雨量有利于提高纤维的纤维强度和可挠度。

Effect of Environment Factor on Fibre Quality of Flax

The results of variety regional test indicated that the differences of environmental condition of climate and soil of different region of Heilongjiang Province are considerable.The differences of flax fibre qualit among different places or the varietyies and places-variety interactions all reach significance level extremely.Therefore it is need to establish high quality region for Heilongjiang Province,and choose the most suitable variety to be planted in the optimum region,to improve totally the flax fibre quality of Heilongjiang Province.Positive correlations were found between fibre strength or flexibility and slowly available potassium or rapidly available potassium content in different regional soil,and the relations among other indexes of soil and two quality indexes are just the opposite.A significantly negative correlation was found between the total phosphorus or rapidly available phosphorus content and flexibility,and the relationship between rapidly available phosphorus content and fibre strength is negative relations.Organic content or the total nitrogen content and fibre strength presents positive correlation,with flexibility are negative relations.The fibre strengths of 3 varieties are negative correlated with sunlight hours before blooming,and after blooming,more accumulated temperature,sunlight hours and rainfall help improving the fibre strength and flexibility.
