Based on years of practical experience in production, we have explored a new breed of herbal flowers that are different from traditional ones. The introduction is as follows. First, sowing propagation Seed treatment. Seed sowing should use seeds full, high vitality, high germination rate of seeds. A bunch of red seeds need to be stirred in warm water at 60°C for 20-30 minutes before sowing. Soak in water for a while, rinse off the pods, rinse with clean water, filter the water, and air dry. It can also be soaked in trisodium phosphate and gibberellin solution, washed and air-dried. 2. Matrix selection. Peat, vermiculite and perlite are all good substrates. Peat and vermiculite were mixed 2:1 and sieved. The matrix can also be self-mixed, and the rotten organic fertilizer, stove ash, and garden soil can be mixed and sieved, and the inorganic fertilizer can not be incorporated, otherwise it will cause no seedling emergence or death after emergence. 3. Determine the tray. According to the size of the seed to determine the plug. On the market there are 72 points, 128 points, 288 points, 293 points and other specifications, a string of red, marigold, Zinnia sows can choose 72 points, petunia, cockscomb, aster can choose 128 points. For used trays, they must be cleaned, sterilized, and dried before they can be used again. 4. sowing. Fill the matrix with the matrix and gently scrape the excess matrix with glass or wood. Do not press hard. Use your fingers to gently press down on the substrate-mounted tray (the depth depends on the size of the seed, usually 1-3 mm), then carefully place the seeds into the tray, 1 capsule per well, and gently cover Fine layers of soil are suitable for the smaller cells. 5. Water spray. Spray water promptly after sowing and spray to the bottom of the tray to seep out. Very small seeds (such as petunias) do not need to be covered with soil, and they cannot be sprayed from above. They must be soaked from below. After soaking, the seed is covered with a piece of white paper to prevent it from being washed away when the water is sprayed and kept moist. When the seeds germinate, the paper is rotten and does not affect the germination of the seeds. Care must be taken when watering, must be poured thoroughly. The soil moisture at the initial stage of sowing may be larger, so as to ensure the water swelling of seeds, the moisture in the later period should not be too much, and the soil can be moist. 6. Germination. After sowing, the trays are moved into the greenhouse for germination. The greenhouse should be shaded properly and keep the room at high temperature and humidity. General temperature control at 25-30 °C, relative humidity above 95%. Different varieties, budding time is slightly different. When the young shoots emerge, they can be removed from the greenhouse and cultivated for 7-10 days. When the seedling height is 5-6 cm, they can be transplanted into the nutritional bowl or pot for conventional cultivation. Second, cutting propagation Prepare before plugging in. (1) Build a seedbed. Choose a well-lit, flat, well-watered plot of land with a rectangular pool of bricks with a height of 30 centimeters. The length and width are determined according to the convenience of cutting, spray pipe setting, and the number of seedlings. The bottom of the pool is covered with a layer of bricks. The pool is filled with coarse sand and flattened. The thickness is not less than 15 cm. (2) Install sprayer. Install a water pipe parallel to the seedbed at a height of 80 cm above the bed, and connect the lower branch pipe to install the sprinkler. According to the range of the nozzle and the water pressure, the density of the nozzle is adjusted to ensure that the cutting seedlings can fully fog. (3) take the net. Use bamboo poles or wooden sticks according to the size of the seedbed to take a 1.8m to 2.6m high shelf and cover the shade net. 2. Harvesting of cuttings. Choose robust plants without pests and diseases, stop fertilizing and stop water for 3-5 days before harvesting, and strengthen light to make it semi-starved to enhance adaptability after cutting. A string of red, chrysanthemum, and marigold flowers that are easy to root at the node should be selected as close to the tip as possible. The cuttings are 7-10 cm long. Most of the leaves are removed and the base is shaved 45 degrees with a blade. The slope is generally 0.5 cm below the point. 3. Cutting time and method. The cuttings are generally made during May-August. Before plugging, insert the matrix with 0.5% potassium permanganate solution to disinfect, then perforate on the inserting bed according to the designed density (generally 800-1000 strains per square meter), and insert the treated cuttings into the holes. With finger compaction, the cuttings and the matrix close, avoid hanging. The cutting depth is preferably 1/3 of the cutting length. 4. Plug in management. Immediately after cutting, spray and pour the seedbed. Spray it for 2 minutes every 5-10 minutes during the day and stop spraying on cloudy days and nights to keep the cuttings moist. General color leaf grass, marigold can be rooted for 6 days, a string of red, National Chrysanthemum 9-10 rooting. After the juvenile roots emerged, the water spray time was gradually reduced and the seedlings were cultivated. After 1 week, they could be transplanted and entered the routine management. Third, the division breeding Dutch chrysanthemum, National Chrysanthemum can also use the ramet method to reproduce. The ramets are generally selected in the shade on a cloudy afternoon in mid-May. The temperature of the early ramets is low and the seedlings are slow; if they are too late, they will affect the growth. When dividing plants, the sprouts should be divided into individual plants and watered immediately after planting. After the soil is slightly dry, the cultivator will be cultivated to increase the temperature of the soil, enhance the permeability of the soil, and shorten the time for seedling easing.
