White orchid cultivation techniques
The white orchid (Mchelia alba) is also known as White Burmese Flower and Burmese Kwai. Magnoliaceae, Laughing Genus. White Orchid is the backbone tree species in the southern gardens. It is also an excellent tree species in the road. In the flowering season, it is fragrant. It makes people feel relaxed and happy. Potted plants can be arranged. In addition to wearing flowers, the flowers can also be smoked and extracted to make them one of the traditional fragrances that our people love. (I) Morphological characteristics Evergreen trees, single leaves alternate, entire, long elliptic, thin leathery, shiny surface, pale green on the back. The flower was born in the same year as the leafhopper, white or slightly yellow, hypertrophic, narrow and long linear, very fragrant. (b) The ecological habits are native to the Himalayas and the Malay Peninsula, and are widely cultivated in the south of the country. The Yangtse River basin and its areas to the north are mostly potted plants. Sexual joyful, warm, moist and well-ventilated environments are not tolerant to overcast or heat and burning. Fear of cold, winter temperatures can not be lower than 5C. Very flavour. Because the root system is fleshy and fat, it is not resistant to dryness and moisture, and it is not suitable for waterlogging. Hi is rich in humus, well-drained, loose and fertile, with acidic sandy soil, wood is more brittle, branches are easily blown off by the wind. In the Gangnam area, three new shoots are made in the year, the first time in the clearing to Guyu, the second in the rainy season, and the third before and after the beginning of the fall. The flowering period is as long as 150 days, and flowering is the most abundant from June to July. (C) propagation methods commonly used pressure strips and grafting. 1. High-pressure reproduction In June to July, select mature biennial shoots with a few severely wounded or ring-striped skins, and then close them with a bamboo tube or flower pot with a humus or moss in place, and use ropes to tie them. Always keep the pots. Wet, rooting after about 2 months, cutting off the mother plant, and planting separately. 2. Grafting and cutting can be used for grafting. According to the connection, in the months of March to March, purple magnolia, which is about 0.6 cm thick, can be selected as the rootstock basin, and it should be connected between April and September, especially from May to June. After about 50 days, the grafted parts heal, and they can be cut off from their mother plants and their management is strengthened. Cut, then use 1 to 2 year thick purple magnolia as rootstock, grafted in mid-March, 20 to 30 days, the top bud leaves, from October to November on the pot, moved into the greenhouse cultivation, when the seedlings can be up to 60 cm ~ 80 cm, faster than growing seedlings. (IV) Management of cultivation and management of white orchids is very important. It directly affects the tree posture and the yield of flowers and must be carefully maintained. The time of going out of the house is generally appropriate from the time of clearing till the valley rain. Before leaving the house, it is necessary to change basins. Generally, the young plants are changed every l to 2 years, and they can be changed every 3 to 4 years after growing up. Adding loose soil is conducive to the development of the roots. Watering is also the key to cultivate white orchids. After spring out of the house, it is better to water at noon, once every other day, but each time must be poured. In summer, the temperature rises and evaporation occurs. Water is sprayed once a day in the morning and evening, and the number of water sprays is appropriately increased in midsummer. Water can be watered in 2 to 3 days in the fall. In winter, watering should be strictly controlled and only the soil and the earth should be kept wet. For post-flowering and weakly growing plants, watering needs to be reduced to prevent shoots from growing or affecting growth. At the same time, the water temperature should not be too cold and should not be much different from that of potted soil. White orchids have lush foliage and long flowering periods. Each 10 days, a cake of water is cooked and the phosphorus and potassium fertilizers need to be added before flowering to facilitate the germination of new leaves and the promotion of flowering. In summer, it is necessary to pay attention to the location of the equipment. The ventilation is not good and it is vulnerable to spider mites and shell insects. During the growing period, diseased branches and dead branches should be cut off, and leggy branches and old leaves should be cut off to prevent tree vigor and promote flower buds. From June to July, they entered the full flowering period and took the fullest aroma of flowers in the morning.
