Potted chrysanthemum grafting technology
First, preparation before grafting 2. Selection of rootstocks: The main stems of Artemisia squamosa are erect and branched, and their herbs are used as rootstocks for many years. There are species such as Artemisia adamensis, Artemisia annua, Artemisia annua, etc. These herbs are distributed at an altitude of 2000-2900 meters and grow in valleys and forest margins. , river beach, Tanabe, and the place. 3. Transplanting rootstocks: At the end of May or early June of the summer season, Aba wormwood, Artemisia annua L. and Artemisia annua, which grows and grows healthy and free of pests and diseases, grows next to the ditch and is transplanted in pots. 4. Scion collection: Use local cultivation to grow vigorously, no pests and diseases, similar flowering time, flower shape fullness, and flower buds to harmonize chrysanthemum's twigs of the year. Immediately after harvesting, trim the scion, remove the base lateral branches and leaves, cut into the scion according to the specifications, and then graft. The scion that can't be grafted is instantly soaked in water, but it can also be connected with picking. Second, the grafting time and method 1. Grafting time: rootstock transplanting pots, etc. After the seedlings are eased, the seedlings grow into a peak period, that is, about 20 days after transplanting, they can be grafted. Grafting must be done on sunny days from 9 to 16. The grafting rate is high. 2. Select Scion: The thickness of the scion should be as thick as the rootstock. The scion is usually 8-10 cm long with 3-4 shoots. 3, Grafting method: usually using a splicing method, the scion base on both sides of the 2-3 cm long wedge-shaped, noodles require smooth and flat, on the rootstock from the main branch 8-12 cm smooth, cut off the main stock, cut The main branch of the rootstock is 2-3 centimeters in length. Then the sharpened scion and rootstock are quickly chopped in a 100ml/L7 GGR, and the spikes are immediately embedded in the rootstock, aligned to form a layer, and the plastic film is tightly bonded from top to bottom, and then the roots of the rootstock shoots are cut off and cut off. leaf. Grafting shape, according to the design requirements, such as to spherical flowers, first cut off the main top of the rootstock, triggering a large number of side branches, and other side branches to a certain extent, according to the spherical surface grafting is complete; if the tower flower, layered grafting, Graft 1 layer every 10 days until the grafting. Third, management after grafting 1. Watering: Sprinkle the water immediately after the scion, and observe it from time to time. When the soil in the pot is yellow, it should be watered. Do not cause too much or less water to cause rot and dead plants or physiological drought. It is best to spend Put plastic bags on pots to increase the humidity around the plants, which will facilitate healing of the plant's interface. 2, in addition to Meng: After grafting, the rootstock can easily grow buds, sprouts, should be erased in time, so as not to compete with the scion to compete for nutrition and water, affecting the survival rate of grafting. 3. Unbundling: After grafting for 20 days, you can loosen and tie the plastic film to survive, but you can't untie the tie, so as not to release the tie prematurely, the interface will not heal well, and it will open and crack, which will affect the survival rate. Wait until the new branch grows to about 15 cm. 4. Thinning and sparse buds: Grafting seedlings will grow many lateral branches after survival. Therefore, we must remove weak or excessive side branches as soon as possible according to design requirements to avoid competition for nutrition and affect the quality of flowers. Generally, we will leave 3-4 strong and healthy lateral branches. . After flower buds, leave 1-2 buds at the top of each branch and remove other buds. For styling grafted flowers, such as spheres, there is a sequential order when grafting. In order to make the flowering period the same, the grafting survives immediately after the survival, and then the side branches are immediately picked up and then they are plucked together with the scion after the grafting. After waiting for flowers to sit, use iron wire or bamboo sticks as a bracket, and put the iron wire ring on the ring to fix the pattern. For early flowering, it is possible to control the light during the growth period, 8-10 hours of sunshine per day, but the shading must be strict, and can not be interrupted; to postpone its flowering, you can add an electric light every day in August-September, when you need to flower, stop the light After that, you will gradually take a bud and blossom. 5. Prevention of pests and diseases: After flowering, buds are highly susceptible to aphids after flowering. After infection, the pots are lifted to the outside and sprayed with a DDV1:1500 solution with a short residual period and low toxicity. The control effect is best. Indoor use of cigarette smoke nicotine solution to control, but the cigarette soda solution should not be too strong, otherwise it will hurt the flowers, with this method to prevent both environmental protection, but also no harm to people, but also to kill aphids. Fourth, summary. Artemisia annua, Artemisia annua L., Artemisia annua L The largest diameter of single grafted chrysanthemums increased from 15 cm before grafting to 25 cm, and the size of flowers was increased by 1-3 times before grafting; the flowering stems were also significantly thickened, increasing by 8-13 mm from 6-9 mm before grafting; The height is also significantly shorter, from 75-120 cm before grafting to 67-93 cm. These have greatly improved the quality of chrysanthemums, and increased the ornamental value for people who love flowers and cultivate flowers. At the same time, grafted chrysanthemums can also enrich varieties, enrich colors, change flower shapes and postures, bring business opportunities to production farmers, and increase commodity value.

1, the choice of matrix: the use of ordinary loess and sawdust in a 2:1 ratio of mixing, and then sprayed with 0.2% potassium permanganate solution wet disinfection. 100 kg of the base plus 5 kg of cooked rapeseed cake and 1 kg of diammonium phosphate were mixed well and placed in a pot.
