【摘要】 纤维亚麻干物质积累与分配特点是随着生育期的进展逐渐增加,后期缓慢下降。成熟期根、茎、叶、蒴果互相之比为0.12∶1∶0.11∶0.29,纤维亚麻的生物产量与原茎产量、原茎产量与经济系数的关系均呈显著的正相关。纤维亚麻由低产变高产应当着重提高生物产量,而由高产再高产应在获得一定生物产量的基础上提高经济系数。更多还原

【Abstract】 The characteristics of accumulation and distribution of fibre flax is gradual increasing with the evolution of growing, and slow decreasing in the final period. In mature period, the ratio of root, stem, leaf and capsule is 0.21 : 1∶0.11 : 0.29. There is positive currelationship between biological yield and proper stem yield as well as between proper stem yield and economic coefficient. The effort to raise the yield from low level to high level should be stressed on the raising of biological yield, while from high level to still higher level should be put on the raising of economic coefficient on the basis of reaching certain biological yield level.更多还原
