Appendix A
Several issues to be noted in seed quality inspection (supplement)
A.1 The moisture content of Kochia scoparia and Kochia scoparia seeds in the south of the Yangtze River confluence can be slightly higher than this standard, but not higher than 13%. A, 2 Non-quarantine pests and diseases shall be restricted by provinces, municipalities and administrative regions according to specific circumstances. A.3 Kochia scoparia has a short life span and can only be stored for a few months. The seed growth rate should be measured based on the seeds harvested that year. If the storage time exceeds 10 months, it will lose its seed value.
Seeds below grade A4 should not be purchased or sold, and are not allowed to be used as seeds. A.5 The inspection of various indicators must be carried out in accordance with GB2930-82 "Inspection Procedures for Pasture Seeds". Additional Notes:
This standard was proposed by the Ministry of Agriculture, Animal Husbandry and Fisheries of the People's Republic of China. This standard was drafted by the Grassland Research Institute of the Chinese Academy of Agricultural Sciences. The main drafters of this standard are Wu Baoguo, Chen Fenglin and Quan Ningyu. 232
