Chervil Profile

Chervil, an annual herb, is one of the common farm weeds. It often grows in farmland such as wheat, corn, soybeans, cotton, etc., and affects the normal growth of crops. It may also become a host and source of infection for many pathogens and pests.

Chervil morphological characteristics

Chervil is 30--45cm high, with many branches and hairless stems. It is triangular-ovate in the basal leaf, expanded into a membranous sheath at the base, with 3--4 pinnate divisions and the final lobes are linear to filamentous. The stem leaves of chervil are often divided into three pinnately. The terminal and lateral compound umbels have no general pedicels or slightly short stalks; no bracts, white or green-white petals, ovoid. The fruit is heart-shaped and ovoid, and the split fruit has 5 edges, round edges, and a very short style. Chervil is an annual herb, 70-120 cm tall. The stems usually have long bristles that are folded outward. Its lower stem leaves are broadly ovoid, 10-20 cm long and 5-10 cm wide, with three-out pinnate divisions. Once the pinna is broad and triangular-lanceolate, 2.5-7 cm long and 1.5 wide. Its petiole is 2.5-7 cm long, with a sheath at the base, which is often hairy. The compound umbels of chervil are terminal or axillary, and the involucre is usually absent. The small involucral bracts of chervil 2-6, linear, 1.5-4 mm long, 1-1.5 mm wide, 1 vein, sparsely marginal eyelashes; small umbels have 9-13 flowers, of which 4-8 male flowers. The flower stalk of chervil is 1-2 mm long; the petals are white, light yellow or light blue-purple, obovate, with a small tongue folded inward at the top. The filaments and petals of celeriac are the same lengths, and the anthers are ovoid. The style of chervil is shorter than the base of the style. The double-hanging fruit is linear and oblong, 7-9 mm long and 1.5-2.5 mm wide, with a beak-shaped tip. The stalk is 3-6 mm long. The flowering and fruiting period of chervil is generally from July to September.

Chervil growth habit and growing environment and distribution

Chervil is produced in Yunnan (Dali, Weixi), Sichuan (Leipo, Hongxi), Tibet. It grows under mountain stream forests and roadside grasslands; altitude is 2100-2800 meters, distributed in Nepal and India. Chervil's origin is on the Caribbean island of Dominica; it is widely distributed in Japan, Malaysia, Indonesia, Oceania, and America.
The current distribution of China is mainly in Zhejiang, Shanghai, Jiangsu (southern), Fujian, Taiwan, Guangdong, Hong Kong, Guangxi, Hubei, and Hunan.

Chervil efficacy and role

Nutritional analysis

The leaves of chervil contain Anthriscusin, carotene, vitamin C, iron, magnesium, and other elements.

Therapeutic effect

Chervil is sweet and has the smell of parsley. The long leaves in the half shade are more scented. It has the effect of stimulating circulation, relieving joint pain, and has a certain auxiliary treatment effect on mucositis.

Chervil Cultivation

Biological characteristics

Chervil is an annual herb, usually growing in fields, wastelands, lawns, roadsides, and often mixed with other weeds. It is also common in farmland. Its flowering period is from April to May, and its fruiting period is from June to July.

Introduce proliferation causes and harm

It was discovered in Hong Kong at the beginning of the 20th century that seeds were often mixed with imported vegetables, especially chervil and carrot seeds. This species is one of the common farmland weeds. It often grows in farmland such as wheat, corn, soybeans, cotton, etc., affecting the normal growth of crops, and may also become a host and source of infection for a variety of pathogens and pests.

Control Method

Chervil has small seeds, and the depth of seed burial has a greater impact on the rate of seedling emergence. Deep plowing the ground before planting is an effective method to prevent the number of seedlings. Fine field management and timely intertillage and weeding are also the main methods to control the harm of chervil. Chemical control methods often choose herbicides such as atrazine and grass cleansing.
