Embodiment 1

[0018] After 100kg of boiling water was cooled, 27g of natamycin and 550g of kojic acid were added to it to prepare a biological preservation solution. Soak 25kg of fresh day lily picked in biological preservation solution for 20-30 minutes, remove, seal and pack in PVC plastic bags, and store at room temperature for 1-2 days. After another 100kg of boiling water was cooled, 25g of natamycin, 550g of kojic acid, 150g of 40% ethephon water agent and 1.5g of ketomethyl jasmonate were added to it to prepare a greening agent. At room temperature, soak the treated day lily that has lost its flowering ability in a chlorotic agent for 1-2 hours, then fish it out, seal it in a PVC plastic bag, and store it for 2-3 days until the green color fades and turns yellow.

Abstract

The invention discloses a pretreatment method for day lily buds before flue-curing barn drying. The pretreatment method comprises the following steps: firstly utilizing cooled boiling water, natamycin and kojic acid to prepare biological preservation solution, soaking picked day lily buds in the biological preservation solution for 20 to 30 minutes, fishing out, sealing, packaging and storing for 1 to 2 days in room temperature to inhibit blooming; then utilizing the natamycin, the kojic acid, 40% ethephon aqueous solution and methyl jasmonate to prepare a chlorox; soaking the pretreated day lily buds losing blooming capacity in the chlorox for 1 to 2 hours under room temperature condition, fishing out, sealing, storing for 2 to 3 days, fading green and presenting yellow. According to the pretreatment method, biological food additives are utilized under low temperature condition, so that the problem of food security caused by chemical additives is avoided. The pretreatment method disclosed by the invention is simple, and is suitable for village farmers, small and micro enterprises and scale enterprises to use and the processing cost is low.
