Kangaroo flower cultivation management method: Soil preparation for bed: The kangaroo flower does not require high soil, and the soil is sandy loam and the land with irrigation conditions is better. It can be made into a bed surface of 1-2 meters and a drainage ditch is opened. Combine farming with base fertilizer (1 ton of decomposed cow dung or pig manure per acre), and apply 5 kg of ferrous sulfate per acre for soil disinfection. Planting technique: planted according to plant spacing 30 cm × 40 cm. When planting, it should not be too deep or too shallow. Generally, the neck of the seedling is flush with the ground, so that it is “not deeply buried, not exposed to the rootsâ€. After planting, pour enough root water, re-cast the next day and pay attention to check. If there is bruise and dew root, re-plant. When planting in the hot season, it needs to be shaded. If it is a potted plant, it is necessary to select the pot according to the size of the seedling. The kangaroo flower is strong in branching, and it should be considered more when selecting the pot. The base of the upper basin is 2 parts of peat soil, 1 part of garden soil and 1 part of sand. Seedling management: Watering: The roots of kangaroo flowers are very thin, and it is easy to lose water. If the topsoil is dry, it should be watered in time. It is necessary to flood the small water to prevent the water from rushing down the seedlings while keeping the bed surface moist. In greenhouse cultivation, watering should not be too diligent, and the humidity should not be too large, because the humidity is too large and it is easy to get black spot disease. Therefore, ventilation and light transmission should also be strengthened. Insufficient light, the plants are thin, the length is easy to fall, the leaves are thin and thin, not easy to flower or flowering, the flower quality is poor, and the flowering period is short. Therefore, proper maintenance of light during flowering is beneficial to prolong flowering and improve flower quality. Shading: Generally, the temperature is high in July-September, and the seedlings grow slowly. Therefore, it is necessary to take necessary shading measures. In the summer high temperature period, shading 30%-60% every day at 9:00-16:00, in suitable light. Under the conditions, the plants are erect, straight, thick and shiny, with lush flowers and long flowering period. Shade, no shading in spring, autumn and winter. Disease prevention: The main disease of kangaroo flowers is black spot disease. This disease spreads quickly. If it is not timely prevented, it can lead to devastating disasters. Can be controlled by 1000 times liquid chlorothalonil, spray once every ten days, the effect is better. Fertilization: Half a month after planting, the new leaves grow and begin to topdress. During this period, high-nitrogen compound fertilizer (30-10-10) is applied, and the concentration is 1500 times aqueous solution, which is applied every 10 days. Adult plants of flower bud differentiation stage should be treated with high-phosphorus potassium compound fertilizer (10-30-20), and the concentration of 1500 times aqueous solution should be applied every 10 days. In addition, after the flowering branches are harvested, the foliar fertilizer is applied according to the growth of the plant, and sprayed with 0.2% potassium dihydrogen phosphate. Cold protection: In winter, the plants will be dormant (some will die completely). During this period, attention should be paid to the cultivation management. No fertilizer is applied below 10 °C, and no water is sprayed at 5 °C. The night temperature after September is maintained at 13-15 °C. It is a necessary condition for flower bud differentiation and elongation, and normal flowering during the Spring Festival. For areas with temperatures below 5 °C, antifreeze protection is required. Or the kangaroo flowers will be cut off at the end of the winter at 10 cm. In this way, the frozen and pest-resistant leaves can be cleaned.
