Study on the effect of different cleaning process on the quality of sugar beet monogerm seeds
[Objective]In order to effectively improve the processing quality of sugar beet monogerm seeds pelleting and explore the cleaning process of monogerm seeds,provide theoretical reference for seed pelleting of sugar beet monogerm.[Methods]By setting different test parameters,the effects of original seed size classification,grinding times,grinding conditions,specific gravity screening and water selection on the quality of sugar beet monogerm seeds were compared and analyzed.[Results]The graded treatment of original seeds could improve the uniformity of beet seed grain size and significantly improve the germination rate,compared with the original seeds without graded treatment(P<0.05).After screening and grading,the germination rate of the polished and regrinding seed was significantly higher(P<0.05)than that of the original seeds(particle size 4.75-5.25 mm),and the germination rate of the grinding twice was the highest 89.30%,which was significantly higher than that of the regrinding once and other polished seeds(P<0.05).The 1 000-grain weight and peeling rate of the seeds after grinding treatment were significantly different from that of the original unpolished seeds(P<0.05).The screening results of different grinding conditions indicated that in the grinding intensity treatment,the germination potential and germination rate of different grinding intensity grades of 2.0-2.5 mm,2.5-3.0 mm,3.0-3.5 mm were significantly different(P<0.05),and the frequency of 35 Hz was significantly higher than that of 40 Hz(P<0.05).The frequency of 35 Hz,time 3 min and 45 Hz and time 1 min had high germination rate,which was suitable for sugar beet monogerm seed grinding.The specific gravity screening results show that the germination rate and 1 000-grain weight of specific weight 2 were the highest,at 85.00%and 9.62 g.In them,the germination rate was significantly higher than that of other seeds except for specific gravity 3(P<0.05),and the 1 000-grain weight was significantly higher than that of other treatment(P<0.05).In water selection test,it showed that the germination potential and germination rate after water selection+back drying 18 h were the highest,with 91.25%and 92.75%respectively,which were significantly higher than other drying conditions(P<0.05),and the water content at this time was 10%.[Conclusion]After a series of cleaning processes such as impurity removal,grading,polishing,specific gravity screening,and water selection,the germination rate of the original seeds of sugar beet monogerm seeds can be effectively improved,which is helpful for the promotion and application of sugar beet monogerm seeds pellet technology.
