Growth environment:

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. 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.

Note:

The small crown flower grows slowly at the seedling stage, if the slope scouring 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.

Mode of reproduction:

Small crown flower commonly used seed propagation, sowing, strip sowing, hole sowing, seed consumption of 0.5-1KG per mu, 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.

Main values:

This kind of flower purplish red, gorgeous, can be used as flowers and plants, in addition to ornamental, but also can be used as medicine. Corolla is a ground cover plant with strong resistance and soil fixation ability, which has fast growth and spread, strong coverage and strong stress resistance, and has a long flowering period (the flowering period is 5-June, and sporadic flowering in Qianjiang can be extended to November after flowering). It can be planted and sloping land in large quantities to prevent soil erosion. Corolla can also be planted in the garden, is a better ornamental ground cover plant.
