亚麻DM(干物质)积累动态呈“S”型曲线,不同生育阶段DM积累速度呈抛物线型。DM积累与分配特点是随着生育期进展逐渐增加,后期缓慢下降。成熟期根、茎、叶、蒴果之比为0.21:1:0。11:0.29。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极显著正相关。亚麻由低产变高产应着重提高生物产量,而高产再高产在获得一定生物产量的基础上提高经济系数。
The dynamics of flax DM (dry matter) accumulation showed “S” curve, and the DM accumulation velocity was parabolic at different growth stages. The characteristics of DM accumulation and distribution gradually increased with the growth of the growth period and slowly decreased in the later period. The ratio of root, stem, leaf and capsule at maturity was 0.21: 1: 0.11: 0.29. The biological yield of flax has a very significant positive correlation with the relationship between the yield of raw stem and the yield of raw stem and economic coefficient. Flax from low yield to high yield should focus on improving biological yield, and high yield and then high yield to obtain a certain amount of biological production based on the economic coefficient.
