Carnation cultivation techniques
Carnations have higher requirements for cultivation techniques and are now described as follows: When planting, the first thing to do is to pay attention to the cultivation of substrates. Field cultivation requires a certain degree of permeability, and a large amount of organic fertilizer must be used to make the soil loose and fertile and reach a certain gap. Degree, and then level the land and build a rake to prepare for planting. The transplanted seedlings generally planted in March can be planted in Daejeon in May. The seedlings transplanted in May can be planted at the latest in June. Early colonization can flower early. The seedlings planted in May can bloom in the middle and late September. The seedlings planted in June should bloom from October to December. Plant spacing is 2525 cm, or 3030 cm, and the number of colonization per acre is about 7000-10000 strains. It can also be planted in mud or pots. Carnations are better than fat. The principle of fertilization is to apply thin fertilizer. In the initial stage of planting, the soil nutrient requirements are low and can be applied once a week. In the intensive growing season from August to September and April to May, more fertilization is needed, which can be done twice a week. In general, fertilization is applied once every 5 days in the early spring and once every 10 days in the winter. Carnations are required to keep the soil moist and achieve a certain degree of permeability. Therefore, there should be no accumulation of water in the rhizosphere, and the summer soil should be kept moist. After planting, when the plant grows to a height of about 20 cm, it is necessary to strip off too many lateral buds. The first stripping is usually done in July and the second stripping and pruning is done in September. How much to leave buds when peeling buds, according to the strength of the plant growth may be set, generally retain 6-7 base buds. After two exfoliation and pruning, the plants were shaped. The types of carnations currently used need to enter the greenhouse for winter. It is generally planted in greenhouses in late October. When transplanting, the plants must carry mudballs and strip unnecessary shoots from their bases. The density planted in greenhouses can be planted more densely than in open fields. After entering the greenhouse, watering, fertilization, and a few times are required. The first time the water is poured, it must be filled with water and the fertilizer should be applied after the flower is collected. After entering the greenhouse, the nylon mesh should be used to pull the grid so that each strain is in a grid so that the plants do not fall down. The grid increases with the growth of the plant and can generally increase to 3-4 layers. Carnations have a lot of diseases and pests, especially disease, including blight, virus disease, leaf spot disease and rust disease. In order to prevent diseases, disease-free cuttings and tissue-cultured virus-free vaccines should be selected. If a diseased plant is found at the seedling stage, the diseased plant must be removed, sprayed, and soil sterilized. The pests are mainly spider mites, aphids, night robbers, cockroaches, etc. They can be sprayed or trapped. Soil and other media must be disinfected with steam or chemicals. The tube can be inserted into the deep surface of the soil and the soil surface can be covered with human steam or drug vapors for disinfection. Exposing the soil and media to sunlight can also achieve the purpose of disinfection. In addition, defoliants, eggs, insect hosts, and weeds should also be removed to control the vectors that infect pests and diseases.
