Rubber tree cultivation techniques
The Ficous elastica is also known as the Indian and Indian rubber trees. Sankoh, genus. The rubber leaves are bright and evergreen. They are common foliage plants and are suitable for potted plants. South China can be cultivated as a landscape tree and street trees. (A) Morphological characteristics and variants Evergreen trees, whole plants smooth, with milk. The leaves are broadly long-handled, thickly leathery, light green, oblong or oblong, full. Young shoots red, bracteate. Cultivated varieties are: Phnom Penh rubber tree (var.aureo-marglnalus), leaves with golden edges, more obvious autumn. Mosaic rubber tree (var.uariegata) with yellow and white markings on the leaf mask. (b) The ecological habits are native to India and Malaysia. They prefer warm and humid weather. Fertile soil is required. Hi light, can also be tolerant to yin, not cold, winter temperatures below 5C ~ 8C vulnerable to freezing damage. The suitable temperature is 20C to 25C. (c) Breeding method Bars and bars can be used. Cutting season is not limited, the temperature can be carried out above 15 °C, the most suitable from May to September. Spring and summer cuttings, selection of 2 years of strong branches for cuttings, autumn insertion can be used for cuttings when robust branches. When inserting, it is necessary to insert the matrix after the glue at the cut-off point is coagulated, or it is dried with charcoal powder and ash. The multiple shoots were inserted into the matrix 1/3 to 1/2. Single bud cuttings were all inserted into the substrate, slightly revealing the top of the stem. Summer can be applied with full-light spray seedling method, generally rooting for 30 days, transplanting after 50 days. The bead can be grown in summer and full, every year the thick branches, circling 0.5 cm to 1 cm, and then paste with mud on the girdling place, about 2 cm in thickness, the outside wrapped with a plastic film to maintain the humidity until After cutting roots into the soil, it is an independent seedling. (d) cultivation techniques rubber trees are mostly greenhouse pots. Potted seedlings should be placed half shade. Seedlings need to be changed every spring. Adult plants can be changed once every 2 to 3 years. During the growth period, cooked cakes and water are applied every 2 weeks. In the summer, watering is needed several times a day. Fall and winter should be reduced watering. At the end of autumn, you must move into a greenhouse or indoors to prevent freezing.
