为了探讨南方地区杂交水稻种子小包装的安全贮藏。我们于1990～1991年利用不同含水量的种子装袋进行了试验。 1 材料和方法供试种子是本公司1990年全州咸水制种基地收获的汕优64,种子质量为1级,种子装袋含水量设置4种水平:11%、12%、13%、14%。包装材料选用无毒的塑料袋,每袋定量为0.5公斤,袋口用钢锯片加热密封,置于仓内贮藏10个月(1990年10月～1991年8月)后,依《农作物种子检验规程》(国标)测定种子发芽率。每一样品作3次重复,重复间误差超过允许差范围的,再作2次重复,用重复间误差在允许范围内的平均数作为所测得的发芽率。
In order to explore the safe storage of hybrid rice seed packaging in southern China. We experimented with bagging of seeds of different water content from 1990 to 1991. 1 Materials and methods The seeds tested were Shanyou 64, which was harvested from the statewide saline water seed production base of the Company in 1990. The seed quality was Grade 1 and the seed bagging water content was set at 4 levels: 11%, 12%, 13% 14%. Packaging material selection of non-toxic plastic bags, each bag of quantitative 0.5 kg, with a hacksaw bag heat sealing, storage in the warehouse for 10 months (October 1990 ~ August 1991), according to “crop seeds Test procedures ”(GB) Determination of seed germination rate. Each sample was repeated 3 times, the error between the repeated exceeds the allowable difference range, and then make two repetitions, with the average error between the repeated error within the allowable range as the measured germination rate.
