Morphological characteristics of firecrackers cultivation techniques of firecrackers

Firecrackers are beautiful flowers, firecrackers bloom luxuriantly, lasting red, flowers like firecrackers, is an ideal hanging green plant on the balcony. Warm ground can blossom all the year round, and it has been seen during the Spring Festival, and it is more beloved. Let's take a look at the knowledge of firecrackers and bamboos.

1. Introduction of firecrackers

Firecrackers are bright red in color, and a large string of drooping Yan is quite spectacular, such as firecrackers. The warm ground blossoms continuously all the year round, and it has been seen during the Spring Festival and is more beloved. Can be potted furnishings, can also be used in flower beds, mountains and rocks, grass. Firecrackers are slender, drooping, luxuriant, long-lasting and red, the flowers are like firecrackers, it is an ideal hanging greening plant on the balcony, and can be used in the greening cultivation of balcony flower ponds, dam tops, slopes and so on. Firecrackers, also known as "firecrackers", "auspicious grass", originated in Mexico and Central America. Firecrackers belong to Scrophulariaceae, and firecrackers belong to perennial herbs. Under suitable conditions, it can blossom all the year round.

Second, the morphological characteristics of firecrackers

Firecrackers are multi-branched tufted semi-vine flowers, about 1m high, the stem is erect at the beginning, the apex is bent and drooping due to the action of gravity. Branchlets whorled, slender, nodes conspicuous. Leaves ovate or linear-lanceolate, mostly reduced and minute. Large panicles consisting of Cymes with many flowers, drooping downward; flowers bright red, Corolla tubular, slightly 2-lipped, ca. 2.5cm. Capsule globose. The flowering period is mainly from March to June, and the warm ground often blossoms all the year round. Firecrackers are 60-100 cm high, with slender stems and branches, longitudinally angled, green, whorled at nodes and many branches. Leaflets opposite or whorled, mostly reduced to scales. Cymes, Corolla long tube-shaped, red, apex inconspicuously two-lipped, upper lip 2-lobed, lower lip 3-lobed.

3. Cultivation techniques of firecrackers

1. Cultivation environment

Firecrackers like light-positive plants, like warm, high-temperature and humid climate, suitable for planting in sunny and ventilated places, and the soil should be sandy loam with good drainage. Strong vitality, exuberant growth, easy cultivation. Most of them are planted in courtyards, fences, flower doors and fences for vertical greening.

two。 Cultivation substrate

Firecrackers planted in the ground require a deep soil layer and good soil permeability. Strong adaptability, the general soil can also grow normally. The seedlings of planting strips were planted in the same year and blossomed the next year. Fertilizer and water must avoid drought, keep the soil moist, and water twice a day in the hot season. Apply dilute liquid fertilizer 1-2 times a month. Plastic maintenance and vertical greening need to set up brackets to guide growth. Do not turn over the vines during the growth period, so as not to damage the tendrils, resulting in poor growth and poor flowering.

3. Key points of cultivation

Firecracker bamboo culture should choose an environment with sufficient light and heat and plenty of fertilizer and water. The cultivation environment is too shady, the plant growth is slender, light long branches without flowering; while the climate is too hot and dry, the plant growth will appear premature senescence. The cultivated soil should be loose, fertile and rich in organic matter. in the peak growing season, liquid fertilizer should be applied 1-3 times a month, the early too thin and dense branches should be pruned, and the plant height should be controlled to prevent the plant from growing excessively.

4. Potted plant management

(1) Upper basin

When a small seedling is installed in a basin or a large plant that has been raised for several years is transferred to a basin, a coarse-grained substrate 2-3 cm thick is first put into the basin bottom as a filter layer, and a fully mature organic fertilizer is sprinkled on it as a base fertilizer with a thickness of about 1-2 cm, then covered with a thin layer of matrix, about 1-2 cm thick, and then put into the plant to separate the fertilizer from the root system and avoid root burning.

(2) pruning

Firecrackers in winter plants into dormancy or semi-dormancy period, to thin, disease and insect, withered, too dense and other branches cut off.

(3) change the basin

As long as it is properly maintained, it will grow very fast, and when it grows to a certain size, we should consider changing it to a larger basin so that it can continue to grow vigorously. The culture soil and composition ratio for basin change can be selected as follows: vegetable garden soil: slag = 3RU 1; orchard soil: medium coarse river sand: sawdust = 4RU 1RU 2; or one of paddy soil, pond mud, rotten leaf soil.

(4) take off the basin

Put the flowers that want to change the pot on the ground, first pat the four sides of the basin with a slap, so that the root system is shaken and separated from the basin wall, put the flowerpot upside down on the left hand, gently clamp the plant with the index finger and middle finger of the left hand, hold the edge of the basin with the wrist and fingertip, hit the bottom of the basin with the right hand, and then use the mother finger to top the root soil down from the bottom hole to let the plant come off. After taking it off, gently pat the basin soil with both palms to let the excess soil fall off.

The above is the knowledge of firecracker bamboo. I hope I can help you.
