Introduction to the Propagation method of alpinia officinalis

Alpinia officinalis has beautiful flowers and beautiful leaves, so it is an indoor foliage plant with great ornamental value. Now, many flower friends will make alpinia angustifolia into small and medium-sized potted plants and watch them in brighter places such as living rooms, offices and halls. In addition, alpinia officinalis can not only be ornamental, but also has a certain medicinal value, and the economic value is relatively high.

Alpinia angustifolia

The ramet propagation of alpinia angustifolia is that the mother plant is taken out of the flowerpot, shaking off the excess potted soil, separating the root system as much as possible, and cutting it into two or more plants with a sharp knife. Each plant should have a considerable root system, and its leaves should be properly pruned to facilitate survival.

The temperature of sowing and propagation is 25Mui / Fahrenheit, which is 30 degrees Celsius, and it sprouts 20 days after sowing.

Alpinia angustifolia was put into a pot and then irrigated with root or watered once. Because its root system is greatly damaged and its water absorption capacity is very weak, it takes about 3-4 weeks to recover new roots. Therefore, it is necessary to control watering within 3-4 weeks after ramet to avoid rotting roots, but the transpiration of its leaves is not affected. In order to maintain the water balance of leaves, it is necessary to spray the leaves once or three times a day. Don't fertilize it these days. After the split, also pay attention to the sun is too strong, should be placed in the shade shed for maintenance.

Introduction of alpinia officinarum L. Culture method of alpinia officinalis

Alpinia officinalis has a relatively high ornamental value, its dark green leaves have irregular golden stripes, in the sun will seem to give the leaves plated with a layer of gold, very eye-catching.

Introduction of alpinia angustifolia

Shape: alpinia angustifolia Latin name is Alpinia zerumbet, alias alpinia officinalis, variegated leaf peach, colored leaf ginger, spotted moon peach, etc., about 1 meter high, dark green leathery leaf long oval-shaped lanceolate, 50-60 cm long, 10-15 cm wide, with irregular golden longitudinal stripes, bright color, such as proper maintenance, golden stripes connected into large pieces, is even more dazzling. It blossoms from June to July, the flower posture is elegant, the flower fragrance is attractive, the panicle is raceme, drooping.

Function: potted alpinia angustifolia is suitable for hall decoration, outdoor cultivation embellishes the courtyard, pool or corner, with a unique style. The ornamental effect of alpinia officinarum is very good on the side of the landscape, the edge of the green space and the courtyard.

Culture method of alpinia officinalis

Habits: like high temperature, humid environment, not resistant to cold, afraid of frost and snow. Like the sun, but also a little shady. Grow well in fertile loam.

Soil: when cultivating alpinia officinalis, we should choose loose soil with good drainage.

Reproduction: commonly used ramet and sowing reproduction. Ramets are propagated in spring and summer and plants with underground roots are dug up to cut off the aboveground stems and leaves. Keep 1/3 of the stem length, cut the rhizome 4-5 cm, each section with 2-3 stems, directly potted or planted in the open field. After planting, it was temporarily placed in a semi-shady place for maintenance, and the normal management was restored after the germination of new buds. The temperature of sowing and reproduction is 25-30 degrees Celsius and germinates 15-20 days after sowing.

Temperature: the optimum growth temperature of alpinia angustifolia is 18 ℃-30 ℃. Avoid cold frost. The overwintering temperature needs to be kept above 10 ℃. In winter, the temperature drops below 4 ℃ and goes into dormancy. If the ambient temperature is close to 0 ℃, it will die of frostbite.

Lighting: alpinia angustifolia is afraid of strong light, so it needs to be preserved in semi-shade, or give it 70% shade. If it is too shady, the leaves will not be bright enough. For indoor maintenance, put it in a brightly lit place as far as possible, and move to outdoor semi-shade or shade for a month every one or two months to accumulate nutrients and restore growth. If you put alpinia officinalis in a semi-shady place in midsummer, the leaf markings will be more obvious.

Moisture: alpinia officinalis likes a humid climate, requiring the relative air temperature of the growing environment to be 60-75%. When breeding, we should pay attention to keep the soil moist and avoid being too dry. In summer and autumn, we should often spray water on the leaves of alpinia officinalis to increase air humidity; in winter, alpinia officinalis is dormant, so we should water less and follow the principle of dry rather than wet.

Fertilization: alpinia angustifolia requires more fertilizer and water, but is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potassium fertilizer. It is required to follow the fertilization principle of "frequent application of light fertilizer, less amount and more times, and complete nutrition". Fertilizing once a month during the growing period, mainly phosphorus and potassium fertilizer.

Pruning: open-field cultivation needs to often remove dense stems and leaves and cut off broken stems and leaves to keep the plant shape beautiful. After 4 years of cultivation, the underground rhizome should be dug up again, the old rhizome should be removed, and the plant should be renewed.

Change the pot: due to the strong tillering ability and rapid growth of alpinia officinalis, the pot is changed every 1-2 years, the leaves are dull and too high, and the stems and leaves are replanted.

Diseases and insect pests: the main diseases are leaf blight and brown spot, so we should pay attention to timely treatment. At the initial stage of the onset of leaf spot, Bordeaux solution was sprayed 2-3 times every 10 days, and brown spot occurred. 70% methyl topiramate wettable powder 1000 times solution could be used to control the disease.

The above is the relevant introduction of this article, I believe you have a simple understanding of this after reading it, if necessary, you can continue to pay attention to the No. 1 home network for more information.

How to raise alpinia officinalis how to cultivate alpinia officinalis

Alpinia officinarum is a perennial shrub plant, which is suitable for breeding alpinia officinalis and ornamental alpinia officinalis. The flower color of alpinia officinalis is more gorgeous and beautiful, and it blossoms more in summer and autumn. Next, let's take a look at the culture method of alpinia officinalis.

Culture method of alpinia officinalis

I. breeding method of alpinia officinalis

The propagation mode of alpinia officinalis is mainly by cutting, which can be divided into two types: water cutting and ramet. When cutting, you should choose the stronger branches, but at the same time, the luxuriant part of the top branches should be kept at about ten centimeters after simple cutting. The cut at the lower end should be kept at half a centimeter, and then the plant cuttings should be inserted into the river sand for planting. Before planting in the soil, all the leaves should be basically removed, and a few pieces can be retained at the top.

2. the culture method of alpinia officinalis-watering

Alpinia officinalis likes the environment of semi-shade. To grow alpinia officinalis, you need to control the wettability of the soil, and the temperature of the soil should be between 15 and 25 degrees. Although alpinia angustifolia likes wet soil, it also has strong drought resistance, so it is also dry and wet, which is more conducive to plant growth.

Third, the culture method of alpinia officinalis-- fertilization.

The fertilization of alpinia officinalis should be carried out when the surface of the basin soil is already dry, so as to ensure that the soil can fully absorb the fertilizer. Alpinia officinalis should not be fertilized too much when the pots have just been changed or the stems and leaves are not so strong.
