摘要
以甬优538种子为材料,研究了不同干燥方式对种子干燥速率及质量的影响。结果表明,干燥温度决定了干燥时间,50℃恒温烘干方式烘干种子和稻谷所需时间比袋式烘干和自然晾干方式显著缩短,由于鼓风作用,开始干燥前8 h袋式干燥方式稻谷水分散失最快;增温干燥提高了种子活力指数,对种子活力影响小,种子活力指数50℃恒温烘干方式较自然晾干、袋式普通烘干和袋式加热烘干分别提高26.3%、22.7%和14.2%,差异显著,袋式加热烘干活力指数较自然晾干和袋式普通烘干略有增加。试验明确袋式鼓风加热烘干方式能够有效缩短种子烘干时间,可以作为南方稻区小规模种子烘干方式。
In this experiment,the effects of drying method on seed quality and drying rate were studied,using rice seed of Yongyou 538 as material.The results showed that drying temperature determined drying duration,50℃constant temperature drying method significantly shortened the drying time compared to bag drying and air-blowing,the water content declined fastest in rice stack of bag drying at the beginning 8 h of the drying duration.Raising temperature drying improved seed vigor index,50℃constant temperature method increased seed vigor index by 26.3%,22.7%and 14.2%respectively,compared to air-blowing,bag ordinary drying and bag heated drying method,bag heated drying slightly increased seed vigor compared to air-blowing and bag ordinary drying.The research indicated that the bag drying method with air blowing and heating effectively shortened the drying duration time,which can provided a reference for small-scale seed drying in Southern rice area.
