Non-toxic seedling raising aqueous solution for tobacco seedling raising link

Abstract

The invention discloses a non-toxic seedling raising aqueous solution for a tobacco seedling raising link. The non-toxic seedling raising aqueous solution comprises 2-10wt% of double-chain quaternaryammonium salt and the balance of water, the double-chain quaternary ammonium salt is didecyl dimethyl chloride / ammonium bromide or octyl decyl dimethyl chloride / ammonium bromide or dioctyl dimethyl chloride / ammonium bromide or alkyl dimethyl benzyl chloride / ammonium bromide; the disinfection method for non-toxic seedling raising in the tobacco seedling raising link comprises a seedling raising site, a seedling raising disc, a sowing site, a seedling raising greenhouse film, a greenhouse frame, a leaf cutting tool and worker disinfection. The non-toxic seedling raising aqueous solution for thetobacco seedling raising link is specially prepared for tobacco seedling raising, has remarkable effects of preventing diseases in the tobacco seedling stage and cultivating disease-free strong seedlings, cannot generate toxic by-products, and cannot cause harm to human bodies and the environment.

Description

technical field [0001] The invention relates to the technical field of agricultural disinfection, in particular to a non-toxic seedling-raising water agent used in the process of tobacco seedling raising. Background technique [0002] Tobacco virus disease, commonly known as tobacco mosaic disease, is the most widely distributed and most common disease in tobacco production. Tobacco virus disease can occur from the seedbed stage to the adult plant stage in the field. The primary infection sources at the seedling stage are mainly soil miscellaneous fertilizers, mixed disease hybrids in seeds, wind and other hosts that are man-made and disease-carrying. After the seedlings are infected, small wounds are produced on the leaves by rubbing to cause re-infection. The disease in the field mainly comes from diseased seedlings, diseased soil and other poisonous plants, etc., and the virus invades the disease through agricultural activities. After the tobacco is infected with the vi...

Problems solved by technology

Common tobacco seedlings are sterilized with 8-10% chlorine dioxide powder. Years of repeated use lead to enhanced drug resistance of bacteria, and the bactericidal effect is not obvious; and the chlorine gas produced will cause harm to the human body and cause inhalation damage; chlorine gas chemistry Lively in nature, unstable at high temperature, prone to fire and explosion
