Water hyacinth grows in shallow water and fertile soil ponds, water depth of about 30 centimeters is appropriate. China's provinces mostly use the mother plant to prevent wintering, stocked in the pond in the spring. High temperature season, breeding rapidly. Suitable temperature is 15 to 30 ℃, below 10 ℃ will stop growing. Usually planted in shallow water or potted. Because of the poor cold tolerance of this species, it should be protected before frost, transferred to the cold room water maintenance, the next year into the pond. Potted plants should make the root system slightly rooted in the soil, and in the growing period of quantitative replenishment of organic fertilizers, the supply of sufficient light, can make its growth strong, flowering more and big.
Water hyacinth in the Pearl River Basin can be natural overwintering, the Yangtze River Basin winter need to protect the overwintering. There are several ways to protect the overwintering
(1) Move the seedlings to the side of the pond with the wind to the sun, and cover with plastic film.
(2) Put in spring water or flowing water and use the water temperature to keep them alive.
(3) Move the seedlings to the field where they will be kept, then slowly sprinkle water to make the roots sink into the mud, flood them with water before the frost and snow come, and drain the seedlings for sunshine immediately after the frost and snow. In North China must take the natural solar greenhouse or sun beds to keep seeds. To the next spring when the temperature reaches 13 ℃ or more will be overwintered water hyacinth seedlings moved to large areas of water, at least 5000 kg per mu. Water hyacinth like group, in order to avoid the wind and waves and dispersal, available draft grass handle, wooden frame or bamboo circle, etc., and later with the growth of water hyacinth and constantly enlarged circle into a piece so far. Also use the water on both sides of the river stocking, leaving the middle of the boat channel, so that neither affect navigation, but also a large increase in green fodder. Water hyacinth in addition to asexual reproduction, but also available seed reproduction.
