一、设想的提出和公式的建立种子贮藏是一门新兴的学科。近年来,对贮藏方法和结果,有过一些报道,但是,稻种要贮藏多少年,种子的含水量、仓温和仓(瓶)内最佳真空度应该是多少?是一个需要解决的问题。在贮藏中,对贮藏年限与采用的种子含水量、仓(瓶)内的温度和真空度,存在一定的盲目性。 Harrington(1972年)提出,种子含水量在5～14%范围内,种子含水量每降低1%,种子寿命延长二倍;仓温在0～50℃范围内每降低5℃,种子寿命延长1倍。宿华同志在1986年《种子世界》第8期11页提出用10gp50=kv-C_(1m)-C_(2t)的估算公式。以种子含水量14%、仓温25℃,稻种可贮藏1年为例,用前者规律去推算,当种子含水量5%、仓温0℃时,稻种可贮藏16384年.
First, the idea put forward and the establishment of formulas Seed storage is an emerging discipline. In recent years, there have been some reports about the storage methods and the results. However, how many years should the rice seed be stored, what is the best vacuum degree of the seed in the seed and the temperature in the bun (bottle)? This is a problem to be solved. During storage, there is a certain degree of blindness to the storage life and the moisture content of the seeds used, the temperature and the degree of vacuum in the bins (bottles). Harrington (1972) suggested that the seed life should be doubled for every 1% decrease in water content of seed by 5-14% moisture content and by 5% reduction in seed temperature at 0-50 ° C Times Comrade Su Hua proposed the formula of 10gp50 = kv-C_ (1m) -C_ (2t) in the eighth issue of 1986 World Seed World. Taking the seed moisture content of 14%, storage temperature of 25 ℃ and rice species stored for 1 year as an example, the law of the former can be used to infer that when seed moisture content is 5% and temperature is 0 ℃, the rice species can be stored for 16384 years.
