cultivation techniques

Planting: change jobs before germination in spring. It can be planted in southern China and potted in northern China, which is convenient for indoor wintering. When potted, a column should be erected in the center of the pot to prepare for the upward winding growth. You can also hang pots for cultivation and appreciation. Potted soil was mixed with 3 parts humus soil, 4 parts garden soil and 3 parts river sand, and a proper amount of fully decomposed organic fertilizer was added as base fertilizer. Loose soil and good drainage system are needed. Change the soil in the basin every year 1 time. After planting, water it 1 time, maintain it in the shade, and then put it in the shade for normal management after rooting and germination.

Illumination temperature: the suitable temperature for growth is 20-30℃. Shade in summer and put it in a shade shed or under a big tree to avoid direct sunlight. Direct sunlight will scorch leaves and dry aerial roots. Although Camptotheca acuminata var. Dark red is shade-tolerant, and it can grow for 2-3 months indoors in the shade, but long-term insufficient light will make the color of leaves fade, which will affect the ornamental effect. In winter, it should be moved indoors for wintering, and the temperature should be kept above 65438 03℃ before it can continue to grow, and it should be placed in a sunny place to receive more sunlight, and the minimum temperature should not be lower than 7℃.

Watering and fertilization: Pay attention to watering during the growth period, especially in the peak season, when the temperature is high and the growth is fast, water should be poured 1 time a day, and the basin soil should always be moist. If the weather is dry, spray water on the leaves and palm columns 2-3 times a day to improve the air humidity, keep the humidity of the palm skin outside the palm column, and make the stems and vines take root and grow. During the growing period, dilute liquid fertilizer should be applied 2-3 times a month, mainly nitrogen fertilizer, and appropriate Trim phosphorus and potassium fertilizer should be applied at the same time. Excessive fertilization can easily lead to overgrowth, long internodes, sparse leaves and reduced ornamental value. In winter, we should reduce watering and master the principle of wetting basin soil. Too much water and too wet will cause root rot and even death.

Shaping and pruning: for potted plants or directly cut potted plants, first erect columns in the pots, or directly hang potted plants for viewing. With the growth of plants, vines are tied to posts, and they are wound up, and the plants are treated with the core to promote branching. When the stems and vines grow to a certain height and the stems and vines at the base appear defoliation and baldness, the plants are cut in different positions in batches to promote the germination of new branches, and the new branches are gradually covered by brown columns and cultivated into columns. It can also be cultivated in hanging pots, and the plants can be cored many times to let them droop naturally. For the pruning method, see the section on shaping and pruning of green radish.
