What is the cause of the flowering of water spinach?
Ipomoea aquatica is also known as bamboo leaf vegetable, water spinach, river-crossing vegetable wèng rattan vegetable. Characteristics: Water spinach has fibrous roots, shallow roots and strong regeneration. The xerophytic type has short stem nodes, flat or nearly round stems, hollow, dark green to light green. The aquatic type has long internodes, and adventitious roots are easy to grow on the nodes, which is suitable for cutting propagation. Child leaves are opposite, horseshoe-shaped, true leaves alternate, oblong, heart-shaped or lanceolate, entire, smooth, dark green and petiolate. Cymes, 1 to several flowers, corolla funnel-shaped, completely flowered, white or light purple. Ovary has two chambers. Capsule, containing 2-4 seeds. The seeds are nearly round, thick-skinned, dark brown, and the 1000-grain weight is 32g-37g. Water spinach likes to be warm and moist, resistant to light and fat. Strong growth potential, the biggest feature is waterlogging resistance and high temperature resistance. It can grow under the conditions of 15℃--40℃ and is resistant to continuous cropping. The requirements for soil are not strict, and the adaptability is wide, so it can be planted in both dry paddy fields and ditches. It can still grow in hot and high temperature in summer, but it is not cold-resistant, and its stems and leaves will die in case of frost. It can be cultivated all year round in high temperature areas. Ipomoea aquatica is a high-temperature and short-day crop, which can be cultivated and seeded in Jianghuai Valley. Rattan salamander, on the other hand, is strict with short sunshine, so it can't blossom and seed in the Jianghuai valley, and can only reproduce asexually.
