How to raise small crown flowers

I. selection of sites

The small crown flower does not have high requirements for the soil, and its adaptability is very strong, but the small crown flower is very afraid of stagnant water, so we also need to pay a little attention to the dredging and drainage capacity of the soil topography when selecting the site.

Second, to promote seedlings

The seeds of Corolla are small and can be sowed in spring, summer and autumn. We should go to the ground carefully before sowing. Secondly, the defect rate of Corolla is very high, so we need to do a seedling promotion, it is best to soak in warm water of 80 °. After natural cooling, the survival rate of sowing will be greatly improved after about 14 or 15 hours. ‍

II. Fertilization

The growth rate of the small crown flower is slow at the seedling stage. In order to prevent the soil erosion of the sowing soil and the healthy growth of the small crown flower, we can choose to mix with the grass of the family Gramineae. After the growth cycle, the small crown flower can absorb all the associated weeds on the ground surface, and the existence of the associated grass can be said to be equivalent to the fertilizer of the small crown flower.

After understanding how to raise the crown flower, the editor will introduce to you what is the most suitable growth condition.

Coronilla varia L. Picture of Corolla: how to raise Corolla / how to propagate Corolla Coronilla varia L. Introduction of small crown flower culture methods and matters needing attention small crown flower is a perennial herb leguminous plant with many branches and creeping growth, the stolon is more than 1 meter long and the natural plant cluster is 20-50 cm high. The root system is strong, the lateral root is well developed, and there are adventitious buds and nodules on the root. Leaves are odd-pinnately compound, leaflets alternate, 11-27 long oval or Obovate. Because the inflorescence is like a crown, and the color of the flower is changeable (that is, from pink to purplish red in the later stage), it is nicknamed variegated Corolla. Pods slender as finger-shaped, 3-12 nodes 2-3 cm long, easily broken, each node contains 1 seed; seeds slender, reniform, dark brown. The small crown flower likes light and is not tolerant to shade and has few diseases and insect pests. Strong growth and strong adaptability. Originated in Europe and southwest Asia. It has been used in China for more than 20 years and in the United States for more than 70 years. The morphological characteristics of the small crown flower is perennial herb, the root system is strong and developed, dense root nodule, its root adventitious bud regeneration ability is strong, can make the root system spread to the horizontal direction. The stem is hollow, angled, the texture is soft and creeping upward, the longest is 180cm, and the branching ability is strong; the leaf buds on the nodes are easy to germinate and form many lateral branches. Leaves odd-pinnate, alternate. Umbels axillary, flowers numerous, pink or light red, creeping growth, stolons up to more than 1 meter long, natural clusters 25-50 cm high. There are adventitious buds and nodules on the sturdy lateral roots. Corolla leaves are odd-pinnate compound leaves, leaflets alternate, 11-27 long oval or Obovate pods slender such as finger-shaped, 3-12 nodes 2-3 cm long, easy to break, each node contains 1 seed * seeds slender, reniform, dark brown. The root system is strong and developed, dense root nodule, and its root has a strong ability of adventitious bud regeneration, which can make the root spread to the horizontal direction. The stem is hollow, angled, soft, creeping upward, the longest can reach 180cm, and the branching ability is very strong; the leaf buds on the nodes are easy to germinate and form a lot of lateral branches. Odd-pinnately compound leaves, alternate. Umbels axillary, with numerous flowers, pink or reddish. The root system is well developed, and the depth of the main root is up to 80 cm after one year, and the horizontal spreading ability is strong. The lateral root penetrates more than 1 meter laterally, and adventitious buds grow on the root, which can form new plants and underground stems. From May to July, umbels are axillary, and most of them are crowned by 14 small wreaths arranged at the top of the pedicel, and the flower color changes from pink in the early stage to purplish red in the later stage, hence the name Corolla flower. Fruit maturity from August to September, pods, such as fingers, with obvious pod nodes, 2-3 cm long, a total of 3-12 nodes, easy to break, each node contains 1 seed. Seeds small and strong, slender reniform, reddish brown. The weight of 1000 seeds is 4.1g, about 240000 seeds per kilogram. The ecological habit of the small crown flower likes the warm and humid climate, but because its root tillering bud is lurking at about 20 cm below the surface, it has a strong ability to survive the cold and overwinter. the green grass period is about 220 days in Xi'an and more than 300 days in Wuhan and Qianjiang. The grass needs more water for its growth, but because of its well-developed roots, it can reach 1.4 meters in one year and 4.8 meters in two years at the foot of Shaanxi highway. There are more than 100 lateral roots per square meter, and they are more drought-resistant. Generally, they can grow normally without irrigation in a place with an annual precipitation of 400 meters and 450 millimeters. Unable to tolerate waterlogging, the root will rot and the whole plant will die after flooding for a few days. The small crown flower is not strict to the soil and can grow on the soil of PH5.0--8.2. Strong growth and strong adaptability. Native to Europe and southwestern Asia. It has been used in China for more than 20 years and in the United States for more than 70 years. The root system of Corolla is well developed. it is used for highway slope protection in Northwest China. its growth can reach 1.4 meters in one year and more than 4.8 meters in two years. There are more than 100 lateral roots per square meter with good drought resistance. generally, they can grow normally without irrigation in the area with annual precipitation of 400m / 450mm. Like sufficient light, not very resistant to waterlogging, long-term stagnant water may lead to plant death. The requirement of soil is not strict, and it can grow on pH5.0-8.2soil. Diseases and insect pests are rare. Matters needing attention in the cultivation techniques of the small crown flower grows slowly at the seedling stage. If the slope erosion problem is not considered for the time being and the management and protection is strengthened, the coverage rate can reach more than 80% within six months. In order to prevent soil erosion as soon as possible, according to different construction time and site conditions, mixed sowing of Gramineae grass can cover more than 80% of the surface in 40 days, and it will take about two years to "eat" all the associated grass species to cover the surface. Once the small crown covers the surface, it will be green and colorful for a long time. Xiao Guanhua has been on the highway in Shaanxi Province for more than ten years, and has been extended to Hunan, Hubei, Henan, Hebei, Shanxi and other places. It has been used on American highways for 60 or 70 years, and it has been well received in all aspects. The method of propagation of Corolla is commonly used in seed propagation, such as sowing, strip sowing and hole sowing. The seed consumption per mu is 0.5-1KG, and it can be sown in spring, summer and autumn. Corolla has small seeds and shallow sowing, so the soil should be carefully prepared before sowing. The hard seed rate of the seeds is as high as 70-80%. The seeds must be treated before sowing. A small number of seeds can be soaked in 15% sulfuric acid for 20-30 minutes, or soaked in warm water of 70-80 ℃, cooled naturally, and soaked for about 12-15 hours before sowing. A large number of seeds are generally crushed by a rice grinder before sowing. The germination rate is generally 40-90%, and some hard grains can not sprout until the second year. The growth of weeds is slow at seedling stage, so weeds should be weeded in time. Once established successfully, weeds can be restrained. Disease control of small crown flower, small crown flower likes light and is not tolerant to shade, and few diseases and insect pests occur. The small crown flower has few diseases and insect pests, has no main harm to citrus, peach and other fruit trees, and can provide habitat for natural enemies. The grass likes light and is not tolerant to shade and has few diseases and insect pests. Strong growth, strong adaptability, cold tolerance, drought tolerance, barren soil requirements are not strict, can grow on the soil of PH5.0--8.2. Pay attention to drainage in the rainy season. It is easy to manage and easy to cultivate. The varieties of Corolla are classified into 55 species of Pterygiaceae, which are distributed in the central sea of Europe and West Asia. There are 3 species of Corolla introduced and cultivated in China. Herbs or shrubs; odd-pinnate leaves, leaflets entire; stipules small, membranous, or large and leaflike; flowers pendulous, arranged in a stalked umbel; calyx short campanulate, lobed 5, subequaling; Corolla yellow, rarely purple, petals long stipitate; stamens 10, disomic (9mm 1), anthers homomorphic; ovary sessile, ovules numerous. Pods slender, Terete, quadrangular or slightly flattened, divided into a seed, oblong pod node; seeds transversely oblong. In 1984, the roots and buds of West German Corolla were irradiated by 60CO in Northwest University of Agriculture and Forestry, from which a new variety of Xifu Corolla was selected. The main characteristics of this variety are as follows: (1) exuberant growth, high grass yield, 1593.4 kg fresh grass per mu, 17% higher than the control West German Corolla; (2) developed root system, the thickest diameter up to 2.5cm, horizontal distribution of 3.0m; (3) low toxicity, the content of β-nitropropionic acid in hay at flowering stage is 30.3mg / g and 31.7mg / g, which is 49.5% 51.9% lower than that of the control. (4) the drought resistance and cold resistance are strong, and the growth is still exuberant in Haiyuan County, Ningxia, where the annual rainfall is 300 mm. In Pengyang County, Ningxia, the lowest temperature up to-28 ℃ can survive the winter safely, tolerate barren and saline-alkali soil, but does not adapt to acid soil and has poor moisture resistance. It was examined and approved by the National Herbage Variety approval Committee in November 1991. The market prospect of this variety has been widely popularized in China's Loess Plateau, Northeast, East China, Southwest, South China and other regions. Corolla is native to Europe, southwest Asia, southern Europe and the eastern Mediterranean. It has been used in China for more than 20 years and in the United States for more than 70 years. Corolla has been widely introduced and planted in North China, East China, Central China, Northwest and other places. The small crown flower likes light, and the suitable temperature is 15 ℃ to 30 ℃, but it has strong cold tolerance and can survive the winter safely at the low temperature of minus 34. If covered with snow, it can also survive the winter in Harbin in the northeast. It has low demand for soil, barren resistance and extensive management. it can grow well in P5.0-8.2 soil, among which it grows best in well-drained and neutral fertile soil. Corolla is resistant to drought and waterlogging and grows well in semi-arid areas with annual precipitation of 400-600 mm, but if the water is stagnant for 3-4 days, the roots rot and the plants die. Corolla is a newly introduced ground cover herbage flower with many flowers, beautiful appearance, bright color, long flowering period, dense stems and leaves, large grass coverage and long green period. the green grass period is about 220 days in Xi'an and more than 300 days in Wuhan. Corolla is suitable to be planted in Northwest, North China, Northeast and South China. Has been planted in Beijing, Shaanxi, Shanxi, Nanjing and other places, growing well. Distribution: 55 species in the world and 3 species in China. The small crown flower looks beautiful, especially when it is in bloom, the color of the flower changes from light red to purplish red. Corolla has rapid growth and spread, large coverage, strong stress resistance, long flowering period (5-June in full bloom, sporadic flowering in Qianjiang can be extended to November), and basically evergreen. It is not only grass, but also flowers are basically evergreen, which has high ornamental practical value. Application value Corolla can be used as lawn and soil and water conservation plants, can be used for soil improvement, soil and water conservation, roadsides and some unmowed places as lawns and soil and water conservation plants. Crown plant stem creeping growth, can effectively prevent Rain Water erosion, prevent soil runoff. In foreign countries, Corolla is mainly used for slope protection on both sides of roads and railways, river lifting and bank consolidation, nursing of reservoir dams, water and soil conservation of eroded slopes and so on. Forage utilization because the fresh grass of Corolla is relatively fresh and tender, with high protein content, it is also a good feed for animal husbandry. As a forage grass, Corolla has luxuriant and delicate stems and leaves, high yield and rich nutrient content. Grass and hay are not lower than alfalfa in terms of nutritional value and digestibility to ruminant livestock. Compared with alfalfa, sheep prefer to eat changeable crown flowers. However, because it contains nitropropionic acid, it is toxic to monogastric livestock and is mainly used as forage for ruminants, which is the limitation of its utilization. It can also be used for mowing hay, green feeding and grazing cattle and sheep. When green feeding and grazing cattle and sheep, in the milder climate areas, the grass can be used every year from the beginning of spring, summer and mid-summer to November-December. Note: China began to introduce in the 1970s, in the production practice, Corolla has toxins, can cause monogastric animal poisoning. According to the green manure effect, it is determined that the water content in the fresh grass of small crown flower is 75.8% Magnum N2.58% Magi P2O50.66% K2O 1.22%. In addition to the nitrogen fixation of root nodules, the cutting ability is good, and it can be cut green from May to November every year. 2000~4000kg per 667m2 fresh grass can be cut three times a year. The first green 2000kg in June, the second 1000kg in August, and the third 800~1200kg in November. The cutting time can also be carried out with the needs of orchard production. Community structure: Corolla can form a rich community as long as it is cultivated for one year. The average thickness of the community is 60~80cm, the richness is 6: 13, the branch density is 496-576 / m2, and the dominance is 75%-86.7%. Compared with the areas without crown flowers in the same orchard (control), perennial malignant weeds are significantly reduced and play a good inhibitory effect on weeds in the orchard, especially thatch, Artemisia annua and other malignant weeds. The garden use of the small crown flower is a ground cover plant with strong resistance and soil fixation ability, with fast growth and spread, strong coverage, strong resistance and long flowering period (the flowering period is 5-6 months, and the sporadic flowering in Qianjiang can be extended to November after the full flowering period). Can be planted and sloping land to prevent soil erosion. Corolla can also be planted in the garden, is a better ornamental ground cover plant. The language of the small crown flower: humility. Small crown flower divination: modesty and elegance are your characteristics. You seldom fail, in addition to your own luck, it is mainly because of your temperament. You are modest to people, have objective analysis, will not let unpleasant events occur, coupled with your temperament, has been more than half successful. Small crown maxim: women are far more infatuated with love than men. Maintenance and management of small crown flowers

Corolla is a perennial herb with strong adaptability, strong growth and less diseases and insect pests. Corolla has been used for more than 20 years in China, but it has been used for many years in the United States. So how can we raise the small crown flower well?

Small crown flower

The small crown flower likes the warm and humid climate, but because its root tillering bud is lurking at about 20 cm below the surface, it has strong cold resistance and overwintering ability. the green grass period is about 220 days in Xi'an and more than 300 days in Wuhan and Qianjiang.
