The method of ramet propagation of Guangdong evergreen

Evergreen has luxuriant growth and well-developed roots, which consumes a lot of nutrients every year. Therefore, it is necessary to turn the basin and change the soil year after year, from February to March. The germination of evergreen is strong, and the tiller buds are easy to be produced at the base, and these new tiller buds can be propagated. Ramet can be combined with turning the pot and changing soil at the same time, the clumpy mother plant can be taken out from the flowerpot, shake off the attached soil, cut according to its natural gap, 3 trees in each clump, smear the incision with plant ash after cutting, and then planted in Yixing purple sand basin of suitable size, evergreen has strong regeneration ability, grows fast after ramet, and can be divided again after 4 years.

Ramet and cuttage culture techniques of Guangdong evergreen alias: coarse rib grass, bright silk grass, Guangdong evergreen. Araceae, a genus of alpinia in Guangdong. It is originally from Guangdong and the Philippines. (1) morphological characteristics: perennial evergreen herbs. The plant height is 40-70 cm, the stem is erect and unbranched, and the internodes are obvious. Leaves alternate, ovate-lanceolate or long oval, dark green, glossy. Petiole long, base sheathlike. The Buddha's flame is light green. It blossoms in late summer and early autumn.

(2) habits: sexual preference for warm, humid and slightly acidic soil environment, shade tolerance, fear of direct light, not resistant to cold. The winter temperature is not lower than 12 ℃. (3) cultivation management: Guangdong Wannianqing prefers a shady and humid environment and is afraid of direct sunlight. It can grow in a shaded place for many years, and the leaves will turn white and wither after a short period of exposure. The suitable temperature for growth is 20-28 ℃, and it is not cold-resistant. It should be kept above 8 ℃ in winter. If the temperature is too low, it is vulnerable to freezing damage. As soon as the leaves fall, they die. Summer high temperature season needs to water every morning and evening, in addition, should also spray water to the surrounding ground, in order to improve air humidity. Watering in spring and autumn should be dry and wet, and watering should be controlled in winter. if the basin soil is too wet at this time, the leaves will easily turn yellow and cause root rot. During the growth period, the basin soil should not be too dry, otherwise the lack of water will easily make the leaves yellow and withered. Liquid fertilizer with more nitrogen and potassium is applied every 15 to 20 days in spring and autumn, and fertilization should be stopped in midsummer. Guangdong evergreen likes loose, fertile, well-drained cultivation substrate and is not tolerant to salt and alkali. The basin soil can be mixed with rotten leaf soil, garden soil and a small amount of river sand. The basin is usually changed once a year or two. The mother plant that has been growing for many years is often creeping and its posture is poor, so it should be renewed by cutting. Guangdong evergreen can also be hydroponically cultured. Cut the stem and insert it into water, continue to culture in a water bottle after rooting, or wash the soil from the root after taking off the pot, then soak it in a transparent glass vase, change the water every 2-3 days, and change the nutrient solution every 10 days. It can also be used with potassium dihydrogen phosphate and ammonium sulfate, diluted by 1000 to 1500 times with water. (4) Culture: ramet and cuttage culture can be used. 1. Ramet culture: ramet can be combined with changing pots in spring. Plant from the pot, the stem base part of the branch cut, slightly dried after the pot, watering should not be too much. 2. Cutting culture: it can be carried out from May to June or September. Select a sturdy tender stem, cut down a section of 12 cm 15 cm long from the top, cut off the lower incision at 0.6 cm below the node, apply plant ash to prevent decay, dry and insert it into a clean plain sand with a depth of 4 cm to 5 cm, keep the basin soil moist and maintain 80% air humidity. Under the condition of 20 ℃ at room temperature, it can take root for 3 weeks after planting. When the root is 2-3 cm long, it can be planted in a pot. Can also cut 15 cm of the apex stem, the top leaves 3 to 5, directly inserted into the water, 2 days after a change of water, can also take root from the node. (5) Diseases and insect pests: bacterial leaf spot and anthrax are often harmed during the growing period, which can be sprayed with 50% carbendazim 600 times solution.
