氮硒肥配施对油用亚麻非结构性碳水化合物及产量和品质的影响
Effects of Combined Nitrogen and Selenium Fertilizer Application on Non-structural Carbohydrates,Grain Yield and Quality of Oil Flax
摘要
Abstract
To investigate the effects of combined nitrogen and selenium fertilizer application on non-structural car-bohydrates,yield,and quality of oil flax,this study utilized Longya 11 as the test material.A two-factor split-plot field experiment was conducted to examine the effects of nitrogen fertilizer(N0:0 kg/ha,N1:75 kg/ha,N2:150 kg/ha)and se-lenium fertilizer(Se:0 g/ha,Se1:30 g/ha,Se2:60 g/ha)on oil flax non-structural carbohydrates,grain yield and quality of oil flax under dryland conditions.The results showed that the content of soluble sugar of stems and leaves decreased gradually with the advancement of growth,while the content of starch of stems was the opposite.Under the same selenium fertilizer level,nitrogen fertilization significantly increased the soluble sugar and starch content of stems and leaves,dry matter accumulation,branch number,valid fruits,seed number grain,yield,and seed protein and oleic acid content,and the N2 level had the highest value,and the increase was greater at maturity stage.Under different nitrogen application levels,the combined application of N1 or N2 and selenium fertilizer significantly increased the soluble sugar and starch content of stems and leaves,the dry matter accumulation,branch number,valid fruits,seed number,1000-seed weight,grain yield,protein,oil content,lignans,and oleic acid content.Among the treatments,N2Se1 treatment significantly in-creased soluble sugar,starch content of stems and leaves and dry matter accumulation at maturity,and the valid fruits,seed number,and the 1000-grain weight were significantly higher than those of other treatments,which were 12.35％,3.89％,4.18％significantly higher than those of N2Se0 treatment,respectively.The oleic acid content of seed of N2Se1 was significantly higher than that of other treatments by 2.44％—25.64％,and the seed yield reached 1 700.50 kg/ha.The results showed that the combined application of 150 kg/ha nitrogen fertilizer and 30 g/ha selenium fertilizer could significantly increase the non-structural carbohydrate content and dry matter accumulation of oil flax stems and leaves in the test area,increase seed yield and oleic acid content,and improve quality.关键词
