Ecological habits of Calystegia

Calystegia prefers mild and humid climates, but is also tolerant of harsh environments and is adapted to sandy soils. Calystegia occurs in coastal areas as a dominant or companion species to sandy, gritty, or gravelly soils, sometimes in single communities on gravel soils of granite, gneiss, or schist near the coast, especially on hillsides where sea spray is common. It is an indicator plant for saline-alkali soil in coastal areas of China with moderate climate.

How Calystegia propagates

Propagation of roots, buds and seeds

In the field, asexual propagation is the main one. The underground stem is brittle and easy to be broken, and new plants can grow from each broken body with nodes. Seedling emerges in spring in North China, flowering in summer, and fruiting from in autumn. The seedlings appear in spring in the Yangtze River Basin, and the flowering period is in spring.

The distribution region of Calystegia

Calystegia is distributed throughout the country; Calystegia is distributed throughout Ethiopia, Asia, Malaya and mainland China.

Calystegia is suitable for moist and fertile soil, but also tolerant of barren, drought. Because of the rapid spread of underground stems, they often form single dominant communities, which do serious harm to farmland and become malignant weeds in some areas. It mainly harms spring wheat, cotton, beans, sweet potatoes, corn, vegetables and fruit trees, especially wheat. Calystegia not only directly affects the growth of wheat, but also leads to lodging of wheat and hinders mechanical harvesting.It is the host of the baby ground tiger.

Plant hazards of Calystegia

Damage reason

Because of the rapid spread of underground stems, Calystegia often forms single dominant communities, which do serious harm to farmland and become malignant weeds in some areas. It mainly harms spring wheat, cotton, beans, sweet potatoes, corn, vegetables and fruit trees, especially wheat. Calystegia not only directly affects the growth of wheat, but also leads to lodging of wheat, which hinders mechanical harvesting. It is the host of small ground tiger. 

Chemical control

In the wheat field, herbicides such as green melon, Liguolong, 2 methyl 4 chlorine, Baicaodi, Pai cao Dan, and giant star should be used. Bean field application of Saike, Guangmiling, Pusst, Huwei, weed burning and other herbicides; You should kill the Calystegia in the corn field.
