融雪剂胁迫对早熟禾发芽及幼苗生长的影响分析

Effect of Snow Melting Agent Stress on Poa Pratensis Germination and Seedling Growth

通过培养实验,研究了氯盐和醋酸盐两类融雪剂对早熟禾发芽及幼苗生长的影响。结果表明:融雪剂影响植物种子萌发,且随融雪剂浓度的升高,植物种子的受害率升高,醋酸盐类融雪剂对早熟禾种子的危害程度低于氯盐类融雪剂;融雪剂还影响植物幼苗生长,随融雪剂浓度的增加,苗高和根长逐渐下降,幼苗受害率升高,幼苗形态变化与种子受害率变化表现出一致性,两类融雪剂均会对幼苗的生长产生抑制,且抑制程度相差不大。因此,建议要高度重视融雪剂使用对环境和植物的影响,尽量使用机械和人工除雪方式,减少融雪剂的使用量及使用浓度。

Through culture experiments,the effects of chloride and acetate snow melting agents on Poa pratensisgermination and seedling growth were studied.The results show that snowmelt affected the germination of plant seeds,and with the increase of snowmelt concentration,the damage rate of plant seeds increased,the harm degree of acetate snowmelt to Poa pratensis was lower than that of chloride snowmelt;Snowmelt also affects the growth of plant seedlings,with the increase of snowmelt concentration,the seedling height and root length gradually decrease,and the seedling damage rate increases,the changes of seedling morphology are consistent with the changes of seed damage rate,the two kinds of snow melting agents can inhibit the growth of seedlings,and the degree of inhibition is not different.Therefore,it is suggested to pay attention to the impact of the use of snow melting agents on the environment and plants,and try to use mechanical and artificial snow removal methods to reduce the amount and concentration of snow melting agents.
