Chrysanthemum is one of the oldest traditional flowers in China. It is elegant and splendid, colorful, autumn season, the natural flowers withered, except for its proud cream. In practice, cultivation of potted chrysanthemums that are plump, dwarfed, and healthy (leaves not fall off, no pests and diseases) is a highly technical and highly detailed task in cultivation management. In order to achieve the purpose of cultivation, the management of each stage must keep up, and the management of the late planting of Chrysanthemum into flowering is particularly important. The overall requirements for the later management of potted chrysanthemums are as follows: The beginning of autumn is to set the head, the frost will be dew and the winter will be seen. 1, the sun should be sufficient. Qiuju is a typical short-day flower. After the jujube grows into plants, when receiving sunlight from different angles, the plants should not be shaded one another to meet their requirements for light. During this period, fertilization should be reduced, the amount of watering should be controlled, and the growth should be controlled. Until the middle of September, buds began pouring water. 2, fertilization should be appropriate. After budding can gradually increase the concentration of fertilizer water, to chrysanthemum dew color, chase the last time fat, available concentrated fertilizer. Do not allow the fertilizer to contaminate the chrysanthemum leaves during fertilization to prevent discoloration and shedding of the leaves and affect the plant shape. In order to make the flowers bright, we must also apply extra-root fertilizer. The foliar spray can be performed with dibasic potassium phosphate 0.05% plus urea 0.1% dilute fertilizer. When dressing fertilizers outside the roots, it can also be mixed with certain liquids to achieve the purpose of curing diseases and pests. 3, we must pay attention to plastic surgery and pest control. With the disappearance of hot weather, the growth of chrysanthemum is also accelerated. When the chrysanthemum grows to 15-20 centimeters in length, it is possible to choose to leave 5-8 branches of uniform growth, similar in height and height, and the rest are cut off and removed at any time. Axillary buds, so that the nutrients concentrated in the top buds, conducive to flower bud differentiation. After budding, according to the shape of the plant, flowering parts, timely sparse too many buds, so that a bud. When branches reach about 30 centimeters, pillars should be established to prevent lodging and damage. Chrysanthemum disease in the later stage mainly includes spot disease and powdery mildew, which can be controlled by 0.3-0.5 degree lime sulfur or carbendazim. Insect pests mainly include borerworms and silkworms, which can be sprayed with dimethoate and dichlorvos. China Agricultural Network Editor
