摘要

To study the production technology of rice seeds,with Lianjing 7 as test material,this paper explores the effects of the key rice seed production,processing and storage technologies( such as nitrogen fertilizer application and management,weeding mode in seed breeding field,temperature control of mechanical drying and water control on seed storage) on the quality of rice seeds. The results show that the optimal application proportion of tillering stage dressing and earing fertilizer is 8: 2,followed by 7 : 3; the best time of weeding is booting stage,with the highest purity; the effect of drying and germination rate is best when the temperature is controlled at 44℃ in mechanical drying process; the seed storage quality and storage costs can be guaranteed when the water content of rice seed is controlled at 18%.
