Method for prolonging safety storage life of taxodium auriculatum germplasm resources

Abstract

The invention provides a method for prolonging the safety storage life of taxodium giganteum germplasm resources, and relates to the field of prolonging the safety storage life of taxodium giganteum germplasm resources. The method for prolonging the safe storage period of the taxodium giganteum germplasm resources comprises the following storage steps: step 1, seed pretreatment: screening mature and full seeds, removing impurities, and spreading and airing; an electric dryer is adopted to assist in drying, so that seed coat cracking caused by exposure is avoided; disinfection treatment: soaking with a 0.3% potassium permanganate solution for 30 minutes, and quickly wiping to kill surface pathogens; 2, strictly controlling the water content, namely performing sampling detection by using a rapid moisture meter, screening the appearance and touch sense, and when the surfaces of the seeds are wet or the seeds are adhered to form clusters, possibly causing the water content to exceed the standard, and performing key detection. Through an intelligent management mechanism, full-batch detection before warehousing is strictly executed, a mechanical arm is adopted to be matched with a weighing sensor, the sub-packaging error is controlled to be + / -0.1 g, and through warehousing detection, the problem that the safety storage period is affected due to the fact that seeds which do not meet the standard specification still exist after warehousing can be prevented.
