1烘干的意义种子在收获后,一般含水分都较高,大多数品种的种子流动性及离散性较差,种子的水分含量越高则流动性及离散性越差,容易粘连或板结,采用机械设备清选时容易造成清选设备堵塞,掺杂在其中的杂质不易被清选出去,因此,种子的水分太高不适于机械设备精选,需要精选前进行烘干处理。并且,种子如果不及时进行烘干处理,遇到早霜冻、连绵阴雨等气候,就会造成种子的霜冻、霉变及发热变质,影响种子的发芽率和活力,不能保证种子的质量,因此收获后的种子急需进行
1 The meaning of drying seeds after harvest, the general moisture content is higher, most varieties of seed liquidity and dispersion is poor, the higher the moisture content of the seeds the poorer the liquidity and dispersion, easy adhesion or compaction, When the mechanical equipment is used for cleaning, it is easy to cause the cleaning equipment to be clogged. The impurities in the cleaning equipment are not easy to be cleaned out. Therefore, the high moisture content of the equipment is not suitable for the selection of machinery and equipment. Moreover, if the seed is not dried in time, the frost, mildew and fever met the frost, mildew and other weather conditions, affecting the seed germination rate and vitality, can not guarantee the quality of seeds, so the harvest After the seeds need to be carried out
