1. Strengthen fertilizer and water management All the other flowers in the hot season will enter a peak of growth in the autumn. At this time, the sun is sunny and the temperature is suitable. It is necessary to increase the co-feeding of fertilizers and water to make the flower plants have a strong vegetative body before the winter season. . For example, gerbera will have another peak of flowering between October and November. Sufficient fertilizer can ensure that the flowers bloom large and bright. Carnations, chrysanthemums, etc., should be placed on the shelves of stems and leaves in September-October. In order to ensure that the stems are thick, fertilization should increase the proportion of phosphorus and potassium fertilizers and increase the organic fertilizer. 2, pay attention to the regulation of flowering Many flowers are ready to bloom during New Year's Day and Spring Festival. Therefore, they should be cultivated or inhibited. For example, if the starry sky is a long-day flower that requires winter flowering, it must begin to fill light from the beginning of September. Normally, light hours are added between 10:00 and 2 a.m. for 4 hours for one month. Chrysanthemums are short-lived flowers that must be filled with light to delay its blossoming. The fill light also stopped filling light from mid-September to 50 days before the expected flowering. For some thermophilic flowers, such as Anthurium, Strelitzia, and Phalaenopsis, attention should be paid to warming if the average daily temperature is lower than 15°C. Lily is cultivated in autumn and winter. In addition to heating at low temperatures, it is necessary to add Light to prevent hidden buds. 3, pest control The fall pests include: Carnation, Gypsophila cynthia, Gerbera chrysogenum, Chrysanthemum larvae, Aphids, Lily pests, etc. Major diseases: Chrysanthemum patchy disease, Rose black spot, Powdery mildew, Carnation leaf spot, Gerbera spot disease, etc. Diseases should be prevented mainly, pay attention to ventilation, reduce air humidity in greenhouses, increase phosphorus and potassium fertilizers, and increase plants Disease resistance, spraying protection and prevention.
