Winter water cultivation of scented buds technical points

Toona sinensis buds are popular health vegetables. The toona sinensis buds cultivated by using the nutrients of the eucalyptus twigs do not require chemical fertilizers or pesticides, and are pollution-free vegetables. The use of hydroponic artificial off-season production, listed before and after the Spring Festival, the price is pretty high sales, considerable benefits. Now introduce its technical points. First, prepare cuttings. Before and after mid-November, grow robust, high-yielding, and good-quality citron trees. Obliterate one or two years of fully mature, disease-free, and roughly 2.5 cm thick dense shoots, or use one-year-old or young-year twigs directly to grow and cut. A small section of about 20 centimeters is used for cutting. It is required that the upper part of each cutting must have a top bud. The cutting must be small and smooth, and do not damage the epidermis of buds and branches. Prior to cutting, insert the lower end of the cutting insert into a “9:20” (gibberellin) solution at a temperature of 20° C. and a concentration of 0.01% and soak for 10 minutes to break the dormancy, and be careful to insert with the soaking. Second, insert the bottle. Select a glass jar with a height of 10 cm and a diameter of 7 cm or a wide-mouth container equivalent to it. After washing with clean water, insert 4 to 6 sticks per bottle. The distance is even and the bottle is filled with about 400 g of clear water (in a container 80% full.) After insertion, the bottles are placed one by one on a nursery bed or on a greenhouse rack to be cultivated. Third, prepare the seedbed. Choose leeward sunny fields or empty flat grounds, press 1.2 meters wide to remove the weeds or crop rakes. After the leveling, open the drainage ditch, and place the inserted bottles in a distance of 7-10 cm. Then the shed covers the membrane and the membrane is tightly sealed around it. Greenhouses should be well-preserved insulation facilities, indoor by 50 cm layer frame to do, stay in the middle of a pedestrian road; can also use plastic greenhouse cultivation, will be inserted branches of the bottle according to the above requirements placed on a greenhouse rack or greenhouse. Fourth, post-insert management. After every 7-10 days of insertion, appropriate amount of fresh water should be added to the bottle once to prevent cuttings from drying out due to lack of water. The temperature of the shed or indoor nursery should be maintained at 25-30°C before sprouting. After sprouting, each bud should be left with a strong bud in time and the remaining bad buds removed. At this time, the seedbed temperature is maintained at 15-25°C during the day and 10-12°C at night. In case of long-term low-temperature weather such as ice and snow frost, insulation measures such as covering the roof with insulation or double arched frames shall be adopted to ensure the healthy growth of axillary buds. V. Harvesting and listing. Usually about 50 days after insertion, the shoots can be as long as 10-25 cm and the young leaves can be gradually harvested when they are purple. Premature harvesting yields are low, but too late are of poor quality. Harvesting is best carried out in the early morning hours. The whole buds will be taken off and put into small bags for every 250 grams or 500 grams, packed or bagged. About 50-100 grams of alum buds are produced per bottle. After the first harvest, the second and third crops can be cultivated in the same way.
