Cultivation of miniature desk flowers

Miniature desk flower chrysanthemum small and exquisite, basin diameter is only 8 centimeters or so, plant height, but 10 centimeters, flower diameter is up to 15 centimeters, flowers than pots, placed on the desk, quite ornamental value. To cultivate miniature flowerheads, we must grasp the following five technical points: Select varieties should be selected short internodes, stout sturdy, full-fledged, leafy hypertrophy and stretch of dwarf or mesotype of large flower genus, but also to choose Excellent varieties sensitive to spraying hormones. Such as the Lingbo fairy, the clouds of the plateau, the Liuxiang, the magnificent, the spring township, the green peony and so on. Timely cuttings at the end of July and early August are the best times for cutting the flowers. The cuttings were too early, the plants grew too high and did not conform to the dwarf plant type; the cuttings were too late, the plant growth was insufficient, and the accumulation of accumulated nutrients was insufficient, the flowering was not great. The cuttings should be full-filled buds, shiny leaves, no pests and diseases, no signs of sprouting lateral buds within the leafhoppers, stalk cuttings were green meaty solid thick apical buds. Cut a bud head about 8 cm long and leave two pieces of leaf cuttings in the upper part. Or after budding, cut bud heads, leave the top three leaves, remove the lower leaves and cut them. The matrix uses clean virgin sand or mature sawdust, coal ash, and ash. After the cuttings are placed in a cool and ventilated place, spray water once every morning and evening, and spray water two or three times before and after noon to promote rooting. After the water and fertilizer management, the rooted juveniles should be planted into the miniature pot as early as possible. The proportion of potted soil is: 5 parts of garden soil, 3 parts of sawdust or coal ash, 2 parts of decomposed organic fertilizer, and appropriate amount of insecticidal and bactericidal pesticides. Due to the short incubation time, small pots and small soil, poor storage capacity and poor water storage capacity, the desk-headed chrysanthemum should be diluted with thin organic fertilizer and be treated with 0.1% urea and 0.05% dihydrogen phosphate every 10 days. Potassium mixture is sprayed on the leaf surface of the leaves until the flower buds pass through. At the same time, pour water every morning and afternoon. When the weather is high on sunny days, water is sprayed around the foliage and the basin at noon and evening. During the cultivation process, new buds sprouting between the leaves and pods must be wiped out in time. Chrysanthemum has many flower buds, only one bud at the top is retained, and the others are all removed (If there is no certainty, one or two side buds can be left to stay. When the normal bud development is normal, then side buds are removed again) to ensure that the top flower blossoms It is gorgeous and big. In addition to the budding time, it is usually appropriate to use a bud-like bean size, which is not suitable for premature or late. Hormone-controlled high plant type dwarf is the main feature of the flower. In order to prevent the chicks from being leggy, 200,000 to 400,000 times of Chlormequat spray blades, backs and stalks, especially the terminal buds, will be used continuously from 10 days after cutting. Usually spray three or five times until the bud. Pest control The desk plant is low in size, and there are not many leaves. Therefore, the leaves must be kept intact. For this purpose, the chrysanthemum seedlings are sprayed with 500 times carbendazim or 800 times thiophanate after spraying on the pot, and then sprayed once every half month. If pests are found, such as aphids, red spiders, etc., insect killer 200 times liquid and dimethoate 1000 times mixture can be used. China Agricultural Network Editor
