作物种子从收获到再播种,要经过一段较长的贮藏时间。在贮藏期间,即使种子已处于休眠状态,也绝不会停止其生命活动,因此,为保证作物种子安全贮藏,应做到以下十个“注意”。 1、注意含水量高的种子不能入库。在严寒低温的情况下,含水量高的作物种子最容易受冻害,最后丧失活力。据试验,玉米含水量在28％时,经-11.8℃短时间冷冻,发芽率即严重下降;当气温下降到-28℃～-30℃时,就会全部丧失发芽能力。因此,在寒冬到来之前,一定要把作物种子的含水量降低到安全水分的标准,这是安全贮藏种子最重要的一条。一般粮食
Crop seeds from harvest to re-sowing, to go through a longer period of storage time. During storage, even if the seeds are already in dormancy, they will never stop their life activities. Therefore, in order to ensure the safe storage of crop seeds, the following ten “notes” should be made. 1, pay attention to high moisture content of seeds can not be stored. In the case of cold and low temperature, crop seeds with high water content are the most vulnerable to frost damage and finally lose their vitality. According to the test, when the moisture content of corn is 28%, the germination rate will drop seriously after short-time freezing at -11.8 ℃. When the temperature drops to -28 ℃ ~ -30 ℃, all germination will be lost. Therefore, before the onset of the winter, the water content of crop seeds must be reduced to the standard of safe water, which is the most important one for safe storage of seeds. General food
