Abstract

The chestnut preservative contains plant growth regulator, such as MH, NAA and 2, 4-D, bactericide, such as DEC and TBZ, and filming agent, such as MS. The chestnut preservative has the functions of preventing rot, keeping freshness, preventing germination and preventing water loss. Chestnut after processed with the chestnut preservative may be stored at normal temperature for over 5 months and cold stored for over 7 months.
