摘要
研究结果显示,增施氮肥促进了亚麻的干物质积累,增加了植株的茎粗和株高,对茎上各个组织(表皮皮层,韧皮部,木质部及髓腔)的生长均有促进作用,从而显著提高了亚麻的原茎产量,同时,由于增施氮肥降低了亚麻的出麻率,导致亚麻纤维产量提高不显著;在对增施氮肥的反映方式和程度上。
Nitrogen nutrition accelerates growing of the plant height and diameter of stem, thus the straw yields of fibre flax are significantly increased by the adding nitrogen fertilizer. A correlation and path coefficient analysis of the components of flax straw yield was conducted and the results showed that plant height and diameter of stem take main effect on straw yield. Analysis of anatomical structure of stem showed that the thickness of each tissue of fibre flax stem and the numbers of fibre cell and fibre bundle in transversesection of stem were increased by adding nitrogen fertilizer. But the fibre percentage was decreased thus the increase of fibre yield was not significant.
