Cutting propagation method
It is usually carried out in late autumn and early winter. After the leaves fall, cut the branches from the ground 5 cm to 10 cm and cut them into cuttings of 10 cm to 15 cm. Every 50 branches are tied into a bundle and stored in a ditch (pit) in the lee of the sun. The ditch is 40 cm deep and 50 cm wide, and the tied branches are arranged vertically in the pit. In the spring of the following year, healing tissue has been formed at the base, and cutting is easy to survive. Pruning and cutting can also be done in March-April in spring. One-year-old robust branches should be selected for cutting, each with a length of 10cm ~ 15cm, and inserted into sand about 1/2. The northern area should be covered with plastic film to keep warm and moisturize, and it can take root in about 1 month.
floor
It is carried out in June and July, and the branches around the plants are bent and pressed into the soil. Because it is easy to take root, there is no need to scratch. Take root after about 1 month. After two months, it was separated from the mother plant, dug up by roots, wintered in greenhouse or cellar, and planted in the next spring.
Factory division
In February and March, the roots of plants are dug out and separated, planted in wet soil, compacted after planting, and watered once after 5 days. It grew very fast that year, and it will blossom in June of 5438+00.
Folding management and maintenance
Abundant water
Perforation fertilization is adopted, that is, uniform perforation is made near the crown. Apply urea and appropriate phosphate fertilizer before flowering. Sprinkle about 0.5kg hibiscus tricuspidata on the root of the crown, and then water it to make the color more gorgeous.
It is necessary to meet its water demand in the germination stage of spring, especially in the dry season in the north, and it is necessary to irrigate frequently. In the hot summer in Hunan, it is necessary to water more to keep moist, and places with difficult water sources can be covered with straw, which has a good moisturizing effect. As the temperature drops, watering should be reduced appropriately after autumn. Generally, when flower buds are colored, water should be properly controlled to control the growth of their leaves and concentrate nutrients on the flowers. The management of hibiscus mutabilis cultivated in Hunan is extensive, because the natural precipitation law is roughly consistent with its growth water demand, and its water demand can be basically met at other times except in midsummer.
Potted wood pods should choose a larger porcelain basin or a vegetarian burning basin. The soil in the basin should be loose and fertile, with good drainage and air permeability, and there should be enough water in the growing season. Moving to the leeward and sunny place in winter can ensure its full dormancy.
illuminate
Mufurong likes cold and sunshine. In cold areas, it should be planted in windy places. If it is too shaded, it will grow slowly and the branches will be slender, which will affect the differentiation of flower buds. It should be slightly shaded in summer. In autumn, pregnant buds need sufficient light during flowering, so insufficient light, coupled with continuous rainfall, is easy to cause falling flowers and buds.
