First, the timely picking of buds is generally open at 5 to 7 pm, and the rainy days will be opened earlier. Picking usually begins 4 to 5 hours before flower buds are opened. If harvesting is too early, buds are not fully opened, affecting yield and quality; if harvesting is too late, the quality after drying is poor. Do not damage the calyx when harvesting. After harvesting, if it is not steamed in time, the buds should be kept in a cool place to avoid sunlight.
Second, the role of timely steaming and steaming is the use of steam to quickly kill the activity of the bud inside the enzyme, to prevent the process of browning due to oxidation caused by discoloration. Therefore, the afternoon of the day when the lily was collected should be steamed in time and must not be delayed until the next day. There are two steaming methods, one is steaming alone, that is, the first boiled water, and then put the bud into the steamer, steaming 8 to 10 minutes; the other is steamed with a large wooden steamer. The steaming cabinet is 2.4 meters long and the base is embedded in the stove. It is sealed at all sides and opens on the side. The inside is divided into 4 layers. Each layer can be placed with 4 bamboo sieves. Before steaming, the pot is filled with 20-25 cm deep water. After boiling, the buds are placed in a bamboo sieve. Then the bamboo sieve is placed in a steam cabinet, and the side door of the steaming cabinet is closed. Steaming can take 20-30 minutes. . The steaming time is very important, the time is too short, the buds are unripe, not easy to dry, and the dried products are not good in flavor; the time is too long, the buds are flat, black after drying, and the quality is poor. The standard for steaming is fresh and cooked inside. The buds are just soft and drooping. The color changes from yellowish green to light yellow.
Third, moderately spread the steamed buds Do not immediately dry the sieve, but should be sieved and placed in a clean, well-ventilated place to dry overnight. The buds that are usually steamed in the afternoon are sprayed until they dry the next morning. (a) Dry bamboo curtains. This method has a short drying time, and the dry finished product rate is 2%~3% higher than that of the bamboo mat exposure. Avoid direct exposure of the buds to the drying surface on the cement tarpaulin or the three-in-soil soil structure because the heat is uneven and it is easy to produce Under the phenomenon of ripening, and the color black, affecting the quality of dry products. Sun can be put away after 3 days of exposure. (b) The drying room is dry. When it cannot be dried in rainy days, it can be dried in a drying room. The temperature of the drying room was first increased to 90°C, and then the day lily was placed. Day lily absorbs heat greatly, the temperature of the drying room drops to 65°C, maintains this temperature for 10 to 12 hours, and finally naturally cools to 50°C until it is dried. Turn over 3 or 4 times during drying. Pay attention to ventilation and humidity. The entire process cannot use sulphur fumigation. (c) Dry air flow. For a large number of processing companies, closed-cycle belt dryers can be used for steam steaming, combined with air drying and dehydration, directly from the production of high-quality day-lily Huanghua dry daylily. After cooling, it is graded, measured, packaged, and finally stored in the collection or directly listed. Using this method to process daylily can overcome the problems of poor color, perishable, and sulphur dioxide residues in dehydration processing in the past. Moreover, the processing of dried daylily is fast, low in loss, bright in color, good in flavor, and long in shelf life.
In addition, lily has a low moisture content, is brittle and brittle, and should be put into a wooden or bamboo container for short-term moisture absorption and softening, so that the water content can reach 15%, which can be packaged and listed or continue to be stored.

Mulch Films are a revolution in the agriculture industry as it presents an economical and environment friendly protective solution for crops and soil. It not only maintains the quality of soil but also aids in the faster growth of plants. By reflecting light, it ensures control on growth of weeds as photosynthesis process will not be carried out.
