加工工艺对包壳大白菜种子质量的影响

Effects of Technological Process on Quality of Encrusted Chinese Cabbage Seeds

摘要: 对大白菜种子进行包壳处理可有效改善种子播种性能。采用四种方法测定了大白菜包壳种子的发芽，不同方法测定结果之间存在明显差异。采用8种包壳材料对种子进行包壳，在增重5倍条件下，不同材料包壳种子的发芽、大小、裂解时间和颗粒强度存在差异。测定了两种包壳材料不同包壳倍数种子的发芽和其它质量指标，结果表明随包壳种子的增大，种子发芽下降，裂解时间和颗粒强度也发生变化，但是两种包壳材料的影响不同。试验结果还表明，在一定范围内，包壳种子表面着色对种子质量没有明显影响。

Abstract: Encrusting of Chinese cabbage (Brassica rapa ssp. Pekinensis) seed could improve its sowing performance. The germinations of encrusted seeds are tested by four methods; there are obvious differences among the germination results by different methods. Eight materials are used for encrusting treatment. The effect of treatments on seed quality of encrusted seeds with 5 times weight increase is different. The effect of weight increase is also tested. The germinations of encrusted seeds are decreased as weight increased, and the splitting time and granulate strength are also affected by weight increase, and there is a difference between the effects of treatments by 2 materials. There is no obvious effect of film coating on seed quality within the limits of weight increase.
