The cultivation of carnations
First, choose seedlings. There are two kinds of carnation cuttings and tissue culture seedlings, and it is better to use virus-free tissue culture seedlings. Seedling quality requirements: 4 leaves 1 heart, stems and leaves intact, thick stems dense, dense thick green leaves, dense waxy, with a complete root system developed, no pests, no virus. Second, colonization. One month before planting, 2000-2500 kilograms of depleted livestock and poultry manure and 100 kilograms of phosphate fertilizer were planted in Mushi and deep-turned. Three days before planting, they were planted again and planted for 1 to 1.2 meters in width and 25 to 30 centimeters in height. It is about 50 cm wide. Manual weeding should not use herbicides. Before planting, use 5-7 kilograms of superphosphate, add 2-3 times the fine soil, add water and mix it with mud, and then plant it with roots. The planting is based on the shallow planting, and the rooting water is poured. The planting density is 25-30 plants per square meter. After 1-2 days of planting, a network of woven nylon net ropes is used to support the nets. A total of 3-4 layers of nets are provided. After the plant grows taller, the layers are pulled up in order and often Stalks get into the grid. Usually the first layer is about 15 centimeters away from the skull, and the other layers are about 20 centimeters apart. Planting time from October to November. Pay attention to the winter covered with 2-3 plastic film or other heating measures. Third, management. Basal fertilizer accounted for 1/3 of the total fertilizer. Topdressing requires thinner fertilizers, mainly nitrogen, phosphorus and potassium ternary compound fertilizers. Fertilization was applied once a week at the beginning of colonization and twice a week during the peak period of colonization. 25-30 days after colonization, the plants had 2-3 lateral buds with obvious leaves when they had grown out of the leaves. One month later, all lateral branches that grew after the first topping were picked and left 3-4 pairs of leaves. For the first time after the first picking, half of the side branches will be re-tipped. Take heart on sunny days. Lateral buds are continuously produced between the leaf buds during growth and must be removed in time. If it is a big flower variety, only one middle bud will be left. Pest control is conducted routinely.
