Cultivation and culture methods of dragon spitting beads

Longtuzhu is native to tropical Africa. Now widely cultivated in various parts of our country, it is a very beautiful indoor potted flower. The flower is born at the top of the branch, the calyx is white, and when it blossoms in summer and autumn, the crimson Corolla protrudes from the white calyx, shaped like a swimming dragon spitting beads, hence the name of the dragon spitting beads. Dragon spit beads like warm and sunny, afraid of cold, dormant or semi-dormant in winter, should be placed in a room above 10 degrees and controlled watering. After the weather is warm in spring, it can be put on the balcony or in the yard, and the summer high temperature season should be properly shaded. Attention should be paid to pruning in cultivation, usually before the sprouting of new buds in early spring, leaving only 10 cm long stalks and cutting off the rest. Put in a sunny place after pruning to promote the germination and growth of new branches and leaves. Old plants cultivated for many years can be pruned in early spring combined with changing pots and blossom around May. In the whole growing season, we should also pay attention to topping and heart-picking, promote how long branches, so that the plant shape is low and plump without brackets.

When potted, we should pay attention to watering, watering too much, basin soil too wet will cause yellow leaves and fall off. At this time, if we strictly control watering and stop using fertilizer, it is also possible to gradually restore seedlings and grow new leaves. If the plant leaves turn yellow and continue to water and fertilize, it will not take a few days for the plant to die completely. Longtuzhu reproduction is very easy, can be used ramet and cuttage. There are more cuttings to propagate. The annual sturdy branches can be selected in the growing season and cut into 10 cm long cuttings, leaving 3 buds on the cuttings. The cut should be smooth, and then the cuttings should be inserted in the plain sandy soil in the basin. The depth of the cuttings is half of that of the cuttings. Keep the basin soil moist properly after cutting and cover it with a thin film pocket. It can take root in about 1 month. Longtuzhu is not only of great ornamental value, but also a folk herbal medicine. The whole plant is used as medicine to treat injuries caused by falls. Cultivation methods and matters needing attention of dragon spitting beads

Dragon spits beads

Longtuzhu can probably know from its name that this flower must be very special, and it is indeed the case. When Longtuzhu blossoms, it will spit out a dazzling little red flower at the crack at the tip of its flower, showing a lot of personality. It is a very suitable flower to be cultivated in greenhouse, but if you want to cultivate an ideal dragon spit bead, you must first understand its growth habits.

First, the growth habits of dragon spitting beads

Like warm, moist and sunny semi-overcast environment, not cold-resistant. The overwintering temperature should be above 15 ℃ and should be kept dry. Long-term lower than 10 ℃ can cause defoliation to death. If the seed is propagated by sowing or cutting, the seed life is short and it will be sown immediately after harvest.

The suitable temperature for the growth of Longtuzhu was 1824 ℃, 1830 ℃ from February to October, and 1316 ℃ from October to February of the following year. The winter temperature is not lower than 8 ℃, and the stems and leaves below 5 ℃ are easy to suffer from freezing injury. The light ones cause defoliation, and the heavy ones cause the tender stems to wither. During the vegetative growth period, the temperature can be higher, the temperature is higher than 30 ℃, as long as the water supply is sufficient, it can still grow normally. On the other hand, the temperature of reproductive growth, that is, the flowering stage, should be lower, about 17 ℃.

The soil uses a rich, loose and well-drained sandy loam. Potted soil or a mixture of peat soil and coarse sand

Second, the culture method of dragon spitting beads

1. Planting

Potted dragon spits beads, generally every 1-2 years to change the pot, the time to change the pot in early spring or after the flower fade. When changing the basin, first use broken tiles to cover the drainage hole, and then put a small amount of bone powder as base fertilizer, then load new culture soil (4 parts of rotten soil, 4 parts of garden soil, 2 parts of sandy soil), plant good plants, and leave 2-3 cm along the mouth for fertilization and watering. After changing the basin, pour through the water, put the seedlings slowly in the shade, and then move to the sunny place for maintenance.

two。 Watering

Longtuzhu is sensitive to water. Stem and leaf growth period to keep saline soil moist, but watering can not be excessive, the amount of water is too large, resulting in only long vines without flowering, even leaves yellowing, withering, root decay and death. Summer high temperature season should be fully watered and properly shaded. It is necessary to reduce watering in winter and make it dormant in order to survive the winter safely.

3. Light

Longtuzhu needs plenty of light in winter and shade when the summer weather is too hot, otherwise the leaves will turn yellow. When the light is insufficient, it will cause vine growth and do not blossom. Flower bud differentiation is not affected by photoperiod, but strong light can promote flower bud differentiation and development. It should not be kept in the dark for too long. If the temperature is above 21 ℃, the flowers will fall for more than 24 hours.

4. Soil

The soil uses a rich, loose and well-drained sandy loam.

5. Fertilizer application

Fertilizer should not be applied too much. Mature thin cake fertilizer and water should be applied every 7-10 days in flowering season, and fertilizer should be applied continuously for 3-4 times. If yellowing is found in the process of cultivation, it can be combined with topdressing and 0.2% ferrous sulfate can make the leaves change from yellow to green gradually.

III. Disease control of dragon spitting beads

Longtuzhu belongs to Verbenaceae, which can cause leaf spot disease, which is caused by the infection of half-known bacteria. At first, it was just a small brown spot. If it is not treated in time, it will produce large black spots, and the leaves will wither and yellow and die. Therefore, once found sick, should immediately use chlorothalonil 800 times liquid, foliar spray, once every 7-8 days, 2-3 times in a row, can be basically cured.

The main pests are shell insects, whitefly, etc., which can be sprayed with 1000 to 1500 times of omethoate. The leaves caused by alkali to the soil can not stretch normally, and the leaves are green and yellow, which can be irrigated with 0.2% ferrous sulfate solution. For mosaic disease and fungal disease, the diseased leaves should be removed in time, ventilation should be strengthened, and the disease can be controlled by keeping the leaves dry.

It is actually very interesting to cultivate strange flowers and plants once in a while. However, no matter which kind of flowers and plants are cultivated, they should control watering, fertilization, light and pest control.

Key points of cultivation and management of dragon spitting pearl
