农作物种子水分含量的高低是种子能否安全贮藏的关键因素。在目前农村各家各户不具备水分测定仪器的情况,通过眼看、手摸、牙咬、耳听等办法,可以综合判断种子水分的含量。下面介绍几种主要作物的种子含水量的感官判断方法。1.稻、麦、玉米等种子水分含量的判断如果用手插入种堆中感到有股冷气,用牙咬时较费力,发出的声音响亮,种子断面光滑,表明种子比较干燥,水分含量12%-13%;如果手掌不易插入堆中,阻力较大,咬时不费力,声音不响,种子断面粗糙,则表明水分含量较高,为15%-16%;用手搅拌种子时,若果穗的残余薄片扬起,种子过筛或从高处落到低处时发生沙沙音,这时种子水分含量为12%-14%。
The moisture content of crop seeds is the key factor in the safe storage of seeds. In the present, every household in rural areas does not have moisture measuring instruments, through the eyes, hand touch, teeth bite, ear and other methods, you can synthetically determine the seed moisture content. The following describes the sensory evaluation of seed moisture content of several major crops. 1. Rice, wheat, corn and other seeds determine the moisture content If you feel the hand into the pile of stock air-conditioning, dental bite more time-consuming, louder and louder, the seed section is smooth, indicating that the seeds are relatively dry, moisture content of 12% -13%; if the hand is not easy to insert into the pile, the resistance is larger, biting effortless, the sound is not ring, the rough section of the seed, then the moisture content is higher, 15% -16% Of the residual sheet raised, sifting the seeds or fall from a height when the occurrence of salsa, when the seed moisture content of 12% -14%.
