摘  要：
运用冷等离子体种子处理技术对苜蓿种子进行非电离幅射处理,研究该技术对于苜蓿种子萌发和田间长势的影响。利用不同剂量的冷等离子体处理苜蓿种子,经过室内发芽试验和田间种植试验,调查发芽势、发芽率、发芽指数、越冬、返青、株高、分枝数、结荚数等,并进行数据分析。结果表明,经不同剂量冷等离子体处理后,种子发芽指标和田间长势均有明显变化。冷等离子体处理后放置4 d、20 d进行室内发芽试验,当供电功率为20 W时苜蓿种子的各项发芽指标均大幅提高,并且具有一致的规律性,处理后放置4 d各项发芽指标均显著高于放置20 d,说明放置时间影响冷等离子体处理效果,随放置时间增加苜蓿种子发芽优势下降。与对照相比,处理后苜蓿种子田间种植越冬性普遍增强,返青期提前,其中供电功率160 W的田间苜蓿株高、分枝数、结荚数提高幅度最大。说明该技术对苜蓿种子室内发芽和田间生长均具有重要影响,在生产上具有使用和推广价值。

摘  要：
Low-tempreature plasma( LTP) treatment of seed before sowing is the largest application of mordern physical method in agricultural production. As a conductor,plasma is known as the four states of matter,belongs to the areas of physical discipline. Low-temperature plasma stimulation plays an important role in optimizing crops in terms of activation of endogenous substances in the seeds rejuvenation,promotion of plant grown,protection against disease,and the maximization of yield. Plasma seed processing technology is the use of high energy aggregation on treating crop seeds within 20 s. The LTP plasma stimulation could improve seed germination and seedling growth. This technology was applied practically and works well now. In this paper,the effects of different intensities of LTP on Alfalfa seeds were investigated on the fourth and twentieth days after treated. The vigor,germination rate,germination index,wintering ability,returning green stage,plant height,tillers and pod growth were compared for treated and untreated seeds. The result shows that LTP could improve alfalfa seeds germination and seedling growth,and advance the reviving stage. There is a great value of using and spreading on production.
