Magnolia indications function hurricane, Tongqiao, headache, nose and nose stuffiness is not pain, toothache embolism, its cultivation techniques points: First, cultivation 1, climatic soil: Xinyi should be cultivated warm and dry sunny slopes. It is best to use loose, fertile black sand with plenty of humus. 2. Planting: (1) Seed breeding. Equinox and Equinox can be sowed: first, turn on, fertilize (fertilizer or compost), make oysters, make a seedbed, mix seed and ash, and soak in warm water for 3-5 days. Remove skin and then soak in warm water for one and a half days. After it is out, cover with straw, often sprinkle water, and maintain a certain temperature, until the species crack, drilled in the seedbed, after sowing cover soil about 3 cm, light pressure: generally two years after transplanting. When transplanting, 23-meter spacing was established and the basal fertilizer was applied to plant the seedlings into the soil. (2) Cutting method. Select strong branches for more than two years and cut into 60-70 cm long cuttings. After the rain in summer and autumn, cut the seedlings in a cloudy day (about 30 cm into the soil). Second, the collection is generally taken when the buds have not been released in the early spring of February to March, and the branches are cut and dried. Third, pest control l, root rot: seedlings are more severe, adult plants also occur. The roots became black at the beginning and gradually rotted, with the above-ground parts drying to death. It usually begins in early June and is severe in July and August. The terrain is low and the incidence of regular water plots is severe. Control methods: Strictly quarantine, ban the afforestation of diseased seedlings, and find out that the diseased plants should be immediately unplugged and burned, eradicate diseased soil, and disinfect the soil with quicklime to prevent the spread. 2, the moth: the newly hatched larvae eat mouth meat, resulting in irregular holes in the leaves, affecting photosynthesis. Control methods: Hand-picked cysts in winter and spring. In the hatching period and young stage, spraying dipterex or 50% marathon emulsion 100 times or 80% dichlorvos EC 800 times in early evening has better control effect.
