Storage and fresh-keeping of cut lily flowers
After the cut flowers leave the mother, the life activities such as transpiration and respiration of branches and leaves are still going on, so the water in the body is constantly lost and the organic matter is constantly decomposed and reduced. If you can not replenish water and nutrition in time, slow down the rate of water loss, flowers will wither in a short time, reduce or lose the commercial value of cut flowers. Therefore, the storage and preservation of fresh cut flowers is very important, which generally includes three contents, namely, pretreatment, storage and after-sale bottle insertion, promotion and preservation. ① pretreatment: cut flowers after harvest need to be pretreated immediately, main

Preparation and processing of Sweet Potato starch
Sweet potatoes can be divided into two types: fresh sweet potatoes and dried sweet potatoes. Starch produced by fresh sweet potato generally belongs to manual production in rural areas, while sweet potato starch factories mostly use dried sweet potato as starch raw material, so it belongs to industrial production. 1. The technological process of producing starch from fresh sweet potato is as follows: raw material selection-washing-crushing-grinding and filtration-mixing-skimming and sitting-skimming-pulping-drying. The production process is as follows: (1) selection of raw materials: due to different sweet potato varieties, their quality and starch content are also different, even if the same variety is in different producing areas.

Seed selection and seed treatment of licorice
Ural Glycyrrhiza uralensis with high content of glycyrrhizic acid and glycyrrhetinic acid was selected. Seed treatment licorice seed coat is hard, impervious, impervious, not easy to germinate, untreated seed germination rate is only 30%-40%, while after skin-breaking treatment, the germination rate can reach more than 90%, so the seeds must be pretreated before sowing. The method adopted is as follows: soak the seeds in 60 ℃ water, cover them with wet cloth for 4 ~ 6 hours to absorb water and expand, dry and then sow.
