Feeding methods in golden phoenix

The cultivation method of Jinfeng impatiens likes sunshine, is afraid of humidity, and is heat-resistant and cold-resistant. It is suitable for being born in loose, fertile and slightly acidic soil, but it is also barren. Impatiens balsamina has strong adaptability, easy survival and rapid growth after transplantation. Water once a day during the growing period and twice a day in hot summer. Pay attention to drainage in rainy days. In short, don't dry the soil and don't accumulate water. Impatiens balsamina has strong viability, good adaptability and few general diseases and insect pests. If the temperature is high and the humidity is high, spraying 800 times of 50% thiophanate-methyl wettable powder can prevent powdery mildew. If leaf spot occurs, it can be controlled with 500 times solution of 50% carbendazim wettable powder. The main pest of Impatiens balsamina is red moth, and its larvae will eat the leaves of Impatiens balsamina. If this pest is found, it can be captured and killed manually. Breeding sunny terrain and loose fertile soil can also grow in poorer soil. Reproduce with seeds. Sowing is carried out from March to September, April is the most suitable sowing time, and the transplanting time is not arbitrary. The growth period is from April to September, and the seeds germinate and grow leaves about one week after sowing in the pot. When it grows to about 8cm, 1-3 plants are cultivated in each pot. When it grows to 20-30 cm, pick the core, and after planting, top the main stem of the plant to enhance its branching ability and plump plant shape. After five leaves, apply decomposed dilute human excrement and urine every half month, and apply phosphate fertilizer and plant ash before and after pregnancy. After the flowers bloom, cut off the pedicel, and don't let the pedicel bear seeds, then the flowers will bloom more vigorously; Picking the basal flowers at any time will promote each branch to blossom one after another. It can bloom in the first half of June and last for more than two months. Before sowing, the seedbed should be watered to keep it moist. Phoenix seeds are small, so you can't water them immediately after sowing, so as not to wash them away. Cover with a thin layer of soil about 3-4 mm, and pay attention to shading. After about 10 days, the seedlings can emerge. When the seedlings grow 2-3 leaves, they should be transplanted and then planted step by step or cultivated in pots. Germination can also be cultivated in greenhouse, but before planting outdoors, seedlings should be strengthened at night. Seeds of impatiens balsamina seedling-raising technology are sown on the culture soil, lightly covered with 0.3 cm, germinated after 5-6 days, and 3-4 true leaves are planted in flowerpots or flower beds with a spacing of 30 cm. Disease control. Powdery Mildew of Impatiens A. Symptoms: The disease mainly occurs on leaves and shoots. Generally, it begins in June, and leaves are covered with white powder after July. Subsequently, small yellow spots were formed in the white powder layer, which gradually became darker and finally became dark brown. B. Transmission route: the pathogen overwinters in the residues and seeds of diseased plants. In the second year, the environment is suitable, and germs spread through wind and rain. August to September is the peak of the disease. C. control method: 1. Don't plant too densely, properly ventilate, strengthen fertilizer and water management, and enhance plant disease resistance. Remove diseased leaves and plants, destroy them centrally, and reduce the source of infection. 2. Use 15% triadimefon wettable powder 1000~ 1200 times solution or 70% thiophanate-methyl wettable powder 1000 times solution for control. Avoid spraying at high temperature above 32℃ to avoid phytotoxicity. 2. Impatiens brown spot disease. Impatiens brown spot, also known as Impatiens leaf spot, occurs all over China. A. symptoms: diseases mainly occur on leaves. At first, the diseased spots on the leaves are small yellow-brown spots, then they expand into circles or ellipses, and then turn into light brown at the center, with brown edges and inconspicuous wheel lines. On the seriously ill leaves, the diseased spots are contiguous, causing the leaves to turn yellow until the plants die. B. Transmission route: The pathogen overwinters on Impatiens remnants and soil plant fragments. In the next year, when the environmental conditions are suitable, the bacteria will spread through the wind and rain. It is easy to get sick in hot and rainy season. C. Control methods 1 Impatiens like fertile sandy loam and are not tolerant to waterlogging. Therefore, sandy loam should be planted to facilitate drainage; Potted impatiens should be watered in time after the rain. At the end of autumn, we should focus on destroying diseased leaves and plants to reduce the source of infection in the coming year. 2. Use 25% carbendazim wettable powder 300~600 times, 50% thiophanate-methyl 100 times or 75% chlorothalonil 1000 times to control the disease at the early stage. Third, Impatiens damping-off disease A. Symptoms: Pathogens mainly infect rhizomes, and the diseased parts turn black or shrink. White mold will grow on it when it is wet. After the plant is infected, the leaves wither and dry within a few days, and then the whole plant dies. B. transmission path: 1. It mainly overwinters in soil or diseased residue in the form of mycelium or sclerotia, and the mycelium in soil saprophytes and does not sleep. 2. In the field, infection mainly depends on contact, that is, the roots, stems and leaves of plants will be infected by hyphae in the soil when they come into contact with the diseased soil. Under the condition of water film, healthy leaves will get sick when they come into contact with the diseased parts. In addition, seeds, farm tools and compost containing bacteria can also spread the disease. C prevention and treatment method: at the initial stage of the disease, spray 75% chlorothalonil wettable powder 600 times, or 60% Dover wettable powder 500 times and 20% methyl chloropicrin EC 1200 times.
