Alias ​​night primrose, Amaryllidaceae Tuberose
Native to Mexico and South America
Perennial herb
Growth habit
Tuberose is warm, moist, and has a sunny environment. It requires fertile, clayy loamy soil and bogey water. There is no dormancy period in the tropics and flowering can occur throughout the year. In other regions, leaves fall asleep in winter.
Morphological characteristics
Tuberose underground with bulbous tubers, basal leaves adjoining, leaves 30-45 cm long, 18 cm wide, sparsely spiked inflorescences at top, 20 flowers per inflorescence, successively open from bottom to top, sustainable About half a month, flower white and fragrant, flowering period from July to August.
Cultivation
Select an altitude of 800 m or less and an annual average temperature of 20°C or above. The entire year is frost-free, the soil is fertile, and irrigation and drainage conditions are good. The leeward sunny plots will be planted 25-30 cm deep in the first half of the planting period, combined with site preparation, and the quality will be decomposed at each hectare. Farmyard manure (except chicken manure) 30 to 45 t, fully mixed with ploughing soil to make hoeing, hoe width 30 cm, ditch depth 20 cm, open waist groove and surrounding drains to be broadcast.
Tuberose usually reproduces with tubers, and can be bred in spring, summer, and autumn. Before the breeding, the cue balls stored in winter are taken out, the sub-balls around the cue ball are removed, and soaked in cold water overnight. Planting depth should master the principle of “deep bulb and shallow boltingâ€. Deep planting is conducive to the growth of tubers, and shallow planting is conducive to flowering. Therefore, it is advisable to plant the large balls that bloom in the year to cover the entire top buds after covering the soil. If you cultivate a ball that cannot bloom in the past, the cover should be thicker. On the prepared surface, double rows were planted with a spacing of 20 cm 15 cm and 225,000 to 300,000 plants per hectare. After planting, it poured water once.
After planting, they should be diligently watered, dry and unfavorable to emergence, over-wet and perishable, and under appropriate humidity conditions, budding can be carried out in about 1 month. When the clumps are grown, they should be soiled and properly watered. "Seedlings" to promote root development and make plants grow robustly. At the stage of pumping lotus flowers, watering should be sufficient to promote vigorous growth and bloom. Keep the soil moist in summer.
Tuberose Hi fertilizer, but not too much fertilizer, or easy to cause leaves long, flowering reduction, in addition to base fertilizer, generally in the bud after unearthing, the stems are drawn, and the application of a thin liquid fertilizer during the bud. Commonly used 2% ternary compound fertilizer (urea, superphosphate, potassium sulfate weight ratio of 1:10:3) solution root watering. Simultaneously use multiple microelement fertilizer 500 times or potassium dihydrogen phosphate 600 times liquid spray. In the later stage of pregnancy, a more effective fertilizer with more phosphorus content should be applied, and 225-375kg of ternary compound fertilizer should be applied per hectare. After application, watering and loose soil are needed to facilitate the absorption of buds. After flowering, fertilizer and water management still need to be strengthened to promote new tuber growth and flower bud formation. When tuberose is afraid of cold, when winter temperatures continue to fall, the tubers should be dug out and sun dried, and they should be packed in sacks according to size and placed in a dry place indoors for storage.
The disease is mainly anthrax.
Can be used 75% thiophanate-methyl WP 1000 times; 80% Anthraquinone WP WP 600 times; 75% chlorothalonil wettable powder 700 times and other spray control, usually with 1:1:200 times The Bordeaux mixture is used for control. The pests mainly include yellow thorax, thrips, and northern China. The yellow thorax can be treated with 10% Chlorohydrogen Chromate 200 to 300 times, and 8% edotdine 3000 times; North China For each hectare, 45 kg of 5% tert-butyl phosphate granules can be used for poisonous soil application, watered by soil after application, or irrigated with 50% phoxim EC 1000 times solution and 48% Le Siben EC 1000 times solution.
When the flower on the bottom of the fragrant inflorescence blooms 1 or 2 flowers, it can be harvested and cut from the base of the stem when harvested. One bundle per 20 branches at flower level, wrapped in soft paper
Using the latest computer graphics and image technology, the patient is placed in a virtual environment, by picking technology, make the person can see on the screen or take the form of virtual figure, according to the change of scene and in the screen prompt to do all kinds of action, to keep the screen scene pattern continues, until finally complete the training goals.
